The present disclosure relates to systems and methods for removable memory cartridges and docking stations compatible with media drive slots, such as slots designed for slim-line optical media drives.
Laptops and servers typically contain one or more dedicated slots or expansion slots for receiving optical drives. The attach rate of optical drives, however, is declining, and many laptops and servers are being ordered without an optical drive, and thus, the dedicated slot is unused. Previous solutions addressing these unused slots have included systems by which an optical drive slot can be occupied by a hard disk drive (HDD) or solid-state memory module, which uses the same electrical interface and communication protocol used by an optical drive. Such memory module has a similar form-factor, dimensions, and other features that allow it to be inserted, electrically coupled, mechanically retained, and ejected like an optical drive.
However, these systems are mounted as fixed drives and do not provide a user-friendly method facilitating, for example, interchangeability and expandability. For example, such systems do not provide drive letter or device persistence, they can be relatively large and bulky, and they provide limited shock and vibration resistance.
Thus, there exists a need in the art for systems and methods for removable memory cartridges and docking stations compatible with unused media drive slots, such as slots designed for slim-line optical media drives. There also exists a need in the art for systems and methods for removable memory cartridges and docking stations that provide expandable storage capacity via interchangeable, removable memory cartridges and permit drive letter or device persistence.
The present disclosure, in one embodiment, relates to a system for data storage. The system may include a removable memory element having data storage devices, and a docking station in electrical communication with a host device and configured for receiving the removable memory cartridge so as to put the host system in communication with the data storage elements of the removable memory cartridge. In one embodiment, the system may further include a memory cartridge configured for receiving the removable memory element from the docking station. The memory cartridge may include shock protection features. In additional or alternative embodiments, the removable memory element may include shock protection features. In some embodiments, the docking station can be dimensioned to fit a standard slim-line media drive slot. In further embodiments, the docking station may include a receiving bay with no top or bottom walls, and the removable memory element may have a height substantially equal to a height of the docking station. The data storage devices of the removable memory element may be hard disks, solid state devices, or any suitable combinations thereof.
In additional embodiments, the system may include a media drive adapter including a data cartridge drive bay configured to accommodate a removable data cartridge, a data cartridge connector configured for data communication with the removable data cartridge when the removable data cartridge is positioned within the drive bay, and a media drive connector configured for data communication with a host system when the media drive adapter is positioned within a media drive slot coupled to the host system.
The removable data cartridge may be configured as a first data storage medium, and the media drive slot may be configured for a second data storage medium, different from the first data storage medium of the removable data cartridge. The media drive adapter may be operated to provide data communication between the host system and the removable data cartridge when the media drive adapter is positioned within the media drive slot coupled to the host system, and the data cartridge is positioned within the drive bay.
In particular examples, the first data storage medium of the removable data cartridge may comprise a magnetic data storage medium and the second data storage medium may comprise an optical data storage medium, for which the media drive slot is configured on the host system. For example, the removable data cartridge may comprise a magnetic disk and the media drive slot may comprise an optical disk drive slot configured for an optical disk drive.
The media drive adapter may also include an ejection mechanism for ejecting the data cartridge from the drive bay, for example based on an eject or dismount command from the host system, or a based on a control input from an eject or mount/dismount button or switch on the media drive adapter itself. The ejection mechanism may include a motor and gear assembly coupled to a cam mechanism, configured for ejecting the removable data cartridge from the drive bay based on the ejection or mount/dismount command from the host computer, or from a user. In addition, the cam mechanism can also be configured for locking the removable data cartridge into the drive bay when the removable data cartridge is inserted into the media drive adapter.
Embodiments of a data storage system may include a removable data cartridge inserted into the media drive adapter. The data storage system may incorporate a damping mechanism coupled between an outer housing of the removable data cartridge and an inner side of the drive bay. The damping mechanism may include one or more resilient members configured to suspend the removable data cartridge within the drive bay, and to provide at least partial mechanical isolation between the drive bay and the removable data cartridge.
In data storage configurations for host systems, a data storage device may include a media drive adapter positioned within a drive slot configured for an optical data storage device. The media drive adapter may include a drive bay and a media drive connector coupled to the drive slot, where the media drive connector is operable for data communication with a host system coupled to the drive slot.
A removable data cartridge may be positioned within the drive bay. The removable data cartridge may include a magnetic data storage medium and a data cartridge connector coupled to the media drive adapter, so that the media drive adapter is operable to provide data communications between the host system and the removable data cartridge via the media drive connector and the data cartridge connector.
Depending on configuration, the media drive adapter may include a cam mechanism operable to lock the removable data cartridge into the drive bay when the removable data cartridge is inserted into the media drive adapter. An ejection mechanism may also be provided, operable to operate the cam mechanism to eject the removable data cartridge from the drive bay, for example based on an eject signal from the host system via the media drive connector, or based on a user input via an eject button or other mount/dismount control feature on the media drive adapter. The device may also include a motion isolation mechanism, for example a mechanism with a resilient damping member operable to suspend the removable data cartridge within the drive bay, with the outer housing of the removable data cartridge spaced from the inner sides of the drive bay to reduce vibrations and provide at least partial mechanical isolation.
While multiple embodiments are disclosed, still other embodiments of the present disclosure will become apparent to those skilled in the art from the following detailed description, which shows and describes illustrative embodiments of the disclosure. As will be realized, the various embodiments of the present disclosure are capable of modifications in various obvious aspects, all without departing from the spirit and scope of the present disclosure. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not restrictive.
While the specification concludes with claims particularly pointing out and distinctly claiming the subject matter that is regarded as forming the various embodiments of the present disclosure, it is believed that the embodiments will be better understood from the following description taken in conjunction with the accompanying Figures, in which:
The present disclosure relates to novel and advantageous systems and methods for removable memory cartridges and docking stations compatible with media drive expansion slots, such as slots designed for slim-line optical media drives. For example, the present disclosure relates to removable memory cartridges and docking stations which are compatible with slim-line DVD slots resident on, for example, late model servers and personal computers.
As discussed above, most server and personal computer chassis contain at least one dedicated mounting slot for an optical disk drive. With the advent of, for example, network based software updates, the necessity of optical media for server installations has been diminished. As a result, many optical slots in modern server installs are shipped unpopulated. Similarly, the attach rate of optical drives is declining in personal computers, and many laptops, for example, are being ordered without an optical drive, thus leaving an unused media slot.
Accordingly, an opportunity exists to fill such media slots with higher capacity removable storage elements.
The stationary cartridge receptacle 102 may be sized and dimensioned such that it is compatible with standard dimensions of a mounting slot for a media drive, such as slots designed for slim-line optical media drives. A traditional slim-line media expansion slot has maximum cross-section dimensions of 12.7 mm×128 mm, or 9.5 mm×128 mm, or other cross-section dimensions. Accordingly, in one embodiment, a stationary cartridge receptacle 102 may be sized and dimensioned such that it is compatible with a media expansion slot having a height of about 12.7 mm and a width of about 128 mm. However, the stationary cartridge receptacles disclosed herein are not limited to being compatible with such dimensions, and the stationary cartridge receptacles may be dimensioned to be compatible with any suitable or desirable dimensions. The stationary cartridge receptacle 102 may be installed in a media drive expansion slot by means similar to those used for optical media drives, and in some embodiments may be “plug and play,” as understood by those skilled in the art. In this regard, the stationary cartridge receptacle 102 may include one or more suitable connectors 106 or connecting means, such as but not limited to a serial ATA (SATA) connector, for operably connecting the stationary cartridge receptacle with the remaining components of the host computing device, such as the processing components, via a bus. While generally intended to be left in a media drive expansion slot for an extended period of time, the stationary cartridge receptacle 102 may be installed temporarily or permanently in the media drive expansion slot. In this regard, the stationary cartridge receptacle 102 may include an eject latch 108, permitting relatively easy removal from the media drive expansion slot. The stationary cartridge receptacle 102 may also include other additional features, such as but not limited to indicator lights 110, etc.
As illustrated in
As indicated above, a removable memory cartridge 104 may be removably positioned partially, substantially, substantially entirely, or entirely within the receiving bay 112 of the stationary cartridge receptacle 102. As such, the removable memory cartridge 104 may be sized and dimensioned such at least a portion of the removable memory cartridge 104 will substantially easily fit and be accepted by the receiving bay 112. In a particular embodiment, as indicated above, the removable memory cartridge 104 may have substantially the same size and dimensions as the receiving bay 112, although slightly smaller than the receiving bay, thereby permitting the removable memory cartridge to fit substantially, substantially entirely, or entirely within the receiving bay. The removable memory cartridge 104 may include data storage or memory elements or devices, such as hard disk drives or solid state devices, and any other hardware and software desired for controlling the data storage devices or providing data storage management. As mentioned above, slim-line slots may have a maximum height of 12.7 mm, 9.5 mm, or other height; such height can provide sufficient clearance for a removable memory cartridge 104 to contain a suitable number of for example, 12.5 mm, 9.5 mm, or 7 mm, 2.5″ (63.5 mm) hard disk drives. However, as technology increases and sizes decrease, it is appreciated that any suitable number, type, and size of hard disk or other drives at any suitable size may be used. Similarly, the removable memory cartridge 104 may additionally or alternatively include any suitable amount of solid state memory devices, which again may increase as technology increases and sizes decrease. The removable memory cartridge 104 may include one or more suitable connectors 118 or connecting means, such as but not limited to a SATA connector, for operably connecting the removable memory cartridge 104 with the stationary cartridge receptacle 102, via connector 114 of the receiving bay. Other suitable connectors also may be used.
In some embodiments, the removable memory cartridge 104 may also include shock and/or vibration protection for the memory elements contained therein. Shock and/or vibration protection may be provided to protect against shock and/or vibration in the x, y, and/or z coordinate directions.
In some embodiments, one or both of the stationary cartridge receptacle 102 or removable memory cartridge 104 may include release devices, such as but not limited to mechanical release mechanisms, that permit the removable memory cartridge to be relatively easily removed or ejected from the stationary cartridge receptacle. In additional embodiments, the release devices may include an actuator 120, such as but not limited to a button or other tactile means, for actuating the release device such that the removable memory cartridge 104 may be released or partially or substantially ejected from the stationary cartridge receptacle, and removed therefrom.
The cartridge receptacle (or media drive adapter) 102 may also include one or more associated control features 121, including, but not limited to, eject and mount/dismount buttons, data formatting and security switches, and similar control features. The indicator lights 110 may be provided in a variety of faun to present related operational or status information, including, but not limited to, light emitting diode (LED) indicators and other visual display elements for indicating the mount/dismount or eject status of removable data cartridge 104, and/or additional operational or status information such as the data read/write status, security status, media format and storage capacity of data cartridge 104.
Similar to the embodiment of
The stationary docking station 202 may include alignment features 214, which may serve to align the removable memory element 206 as it is received by the receiving bay 210. In one embodiment, the alignment features 214 may extend from the stationary docking station 202 to assist in the insertion process of the removable memory element 206. Generally, during operation of the system 200, wherein the removable memory element 206 is positioned within the receiving bay and being accessed through the stationary docking station 202, and in idle states, the alignment features 214 will normally be retracted within the stationary docking station 202, generally within or near the receiving bay 210. The alignment features 214 may actuate and extend out form the stationary docking station 202 upon commencement of the insertion process for the removable memory element 206. While generally illustrated as having two extension arms that extend and retract for assisting in the insertion process for the removable memory element 206, the alignment features 214 as shown are provided for illustrative purposes, and the actual implementation of alignment features 214 may differ from those shown, and in some embodiments for example, may reside instead on the memory cartridge 204 or removable memory element 206. Similarly, in other embodiments, the alignment features 214 may include fixed structures, such as but not limited to grooves, notches, etc., as opposed to structures that extend and retract, to assist in the insertion process of the removable memory element 206.
The memory cartridge 204 may act as a carrying case and/or a protective shell for the removable memory element 206. The memory cartridge 204 may, in some embodiments, include shock and/or vibration protection for the removable memory element 206 contained therein, such as but not limited to shock and/or vibration bumpers 218 or an internal cradle element 218 that can be configured for cradling the removable memory element 206, and which may be composed of a material and design suitable for providing protection for the removable memory element from shock and vibration. In this regard, shock and/or vibration protection may be provided to protect against shock and/or vibration in the x, y, and/or z coordinate directions.
As indicated above, a removable memory element 206 may be removably positioned partially, substantially, substantially entirely, or entirely within the receiving bay 216 of the memory cartridge 204 and may be transferred to a position partially, substantially, substantially entirely, or entirely within the receiving bay 210 of the stationary docking station 202. As such, the removable memory element 206 may be sized and dimensioned such at least a portion of the removable memory element 206 will substantially easily fit and be accepted by either receiving bay 210, 216. In a particular embodiment, as indicated above, the removable memory element 206 may have substantially the same size and dimensions as the receiving bays 210, 216, although slightly smaller than the receiving bays, thereby permitting the removable memory element to fit substantially or entirely within the receiving bays. The removable memory element 206 may include data storage or memory elements or devices, such as hard disk drives or solid state devices, and any other hardware and software desired for controlling the data storage devices or providing data storage management. As mentioned above, a traditional slim-line slot has a maximum height of 12.7 mm or 9.5 mm, or other maximum height; such height can provide sufficient clearance for a removable memory element 206 to contain a suitable number of, for example, 7 mm, 2.5″ (or 63.5 mm) hard disk drives. However, as technology increases and sizes decrease, it is appreciated that any suitable number, type, and size of hard disk drives at any suitable size may be used. Similarly, the removable memory element 206 may additionally or alternatively include any suitable amount of solid state memory devices, which again may increase as technology increases and sizes decrease. The removable memory element 206 may include one or more suitable connectors 220 or connecting means, such as but not limited to a SATA connector, for operably connecting the removable memory element 206 with the stationary docking station 202, via the connector 212.
To remove the removable memory element 206 from the stationary docking station 202, the memory cartridge 204 may again be positioned adjacent to the receiving bay 210 of the stationary docking station. An eject mechanism of the stationary docking station 202 may be actuated, thereby causing the removable memory element to be ejected from the receiving bay 210 and into the receiving bay 216 of the memory cartridge 204. As with the insertion operation, in one embodiment, the alignment features 214 may be extended toward and into the memory cartridge 204. In further embodiments, the alignment features 214 may align with, operably couple with, or otherwise attach with the latching alignment receptacles 222 in the memory cartridge 204. The alignment features 214 may assist in accurately positioning the removable memory element 206 relative to the receiving bay 216 of the memory cartridge 204, and may guide the ejected removable memory element into the receiving bay of the memory cartridge. Once the removable memory element is positioned at least partially within the memory cartridge 204, the alignment features may be retracted back into the stationary docking station 202.
In another embodiment, illustrated in
The stationary cartridge receptacle 302 may be sized and dimensioned such that it is compatible with standard dimensions of a mounting slot for a media drive, such as slots designed for slim-line optical media drives. As discussed above, a traditional slim-line media expansion slot has maximum cross-section dimensions of 12.7 mm×128 mm, 9.5 mm×128 mm, or other dimensions. Accordingly, in one embodiment, a stationary cartridge receptacle 302 may be sized and dimensioned such that it is compatible with a media expansion slot having a height of about 12.7 mm or 9.5 mm and a width of about 128 mm. However, the stationary cartridge receptacles disclosed herein are not limited to being compatible with such dimensions, and the stationary cartridge receptacles may be dimensioned to be compatible with any suitable or desirable dimensions. Additionally, in some embodiments, the stationary cartridge receptacle 302 may be particularly configured to enable the use of expanded capacity 12.5 mm thick HDDs. In this regard, the 12.7 mm (or other) height of the standard slim-line media expansion slot form factor restricts the maximum thickness of a removable memory cartridge which can inserted into the stationary cartridge receptacle. For example, in the case of 2.5 inch form-factor HDDs, the 12.5 mm height of the drives would nominally not have enough clearance to fit into a stationary cartridge receptacle designed for a slim-line media expansion slot, such as that of the embodiment of
The stationary cartridge receptacle 302 may be installed in a media drive expansion slot by means similar to those used for optical media drives, and in some embodiments may be “plug and play,” as understood by those skilled in the art. In this regard, the stationary cartridge receptacle 302 may include one or more suitable connectors or connecting means, such as but not limited to a serial ATA (SATA) connector, for operably connecting the stationary cartridge receptacle with the remaining components of the host computing device, such as the processing components, via a bus. While generally intended to be left in a media drive expansion slot for an extended period of time, the stationary cartridge receptacle 302 may be installed temporarily or permanently in the media drive expansion slot. In this regard, the stationary cartridge receptacle 302 may include an eject latch, permitting relatively easy removal from the media drive expansion slot. The stationary cartridge receptacle 302 may also include other additional features, such as but not limited to indicator lights, etc.
As illustrated in
The receiving bay 306 may include one or more suitable connectors or connecting means, such as but not limited to a SATA connector, for operably connecting the removable memory cartridge 304 with the stationary cartridge receptacle 302. The stationary cartridge receptacle 302 may include one or more electrical components provided, for example, in a printed circuit board assembly interconnected between the connector and the connector of the stationary cartridge receptacle, discussed above. The electrical components, such as the printed circuit board assembly, may be used to, for example but not limited to, translate communications received by the processing components of the server or personal computer to communications that would be understood by the removable memory cartridge 304 or to perform data storage management tasks.
As indicated above, a removable memory cartridge 304 may be removably positioned partially, substantially, substantially entirely, or entirely within the receiving bay 306 of the stationary cartridge receptacle 302. As such, the removable memory cartridge 304 may be sized and dimensioned such at least a portion of the removable memory cartridge will substantially easily fit and be accepted by the receiving bay 306. In a particular embodiment, as indicated above, the removable memory cartridge 304 may have substantially the same width as the receiving bay 306, although slightly smaller in width than the receiving bay, thereby permitting the removable memory cartridge to fit substantially or entirely within the receiving bay. The removable memory cartridge 304 may include data storage or memory elements or devices, such as hard disk drives or solid state devices, and any other hardware and software desired for controlling the data storage devices or providing data storage management. As mentioned above, a traditional slim-line slot has a maximum height of 12.7 mm or 9.5 mm, or other height; such height can provide sufficient clearance for a removable memory cartridge 304 to contain a suitable number of, for example, 7 mm, 2.5″ (63.5 mm) hard disk drives. However, as technology increases and sizes decrease, it is appreciated that any suitable number, type, and size of hard disk drives at any suitable size may be used. Similarly, the removable memory cartridge 304 may additionally or alternatively include any suitable amount of solid state memory devices, which again may increase as technology increases and sizes decrease. The removable memory cartridge 304 may include one or more suitable connectors or connecting means, such as but not limited to a SATA connector, for operably connecting the removable memory cartridge 304 with the stationary cartridge receptacle 302, via the connector of the receiving bay.
In some embodiments, the removable memory cartridge 304 may include shock and/or vibration protection for the memory elements contained therein. In one embodiment, shock and/or vibration protection may be incorporated in a ring or circumference 314 of shock and/or vibration protection material or coating partially or fully circumferentially surrounding the removable memory cartridge 304. However, other variants of shock and/or vibration protection are contemplated by, and within the scope of the present disclosure. As indicated above, this may permit shock and/or vibration protection against shock and/or vibration in the x, y, and/or z coordinate directions.
In some embodiments, one or both of the stationary cartridge receptacle 302 or removable memory cartridge 304 may include release devices, such as but not limited to, mechanical release mechanisms, that permit the removable memory cartridge to be relatively easily removed or ejected from the stationary cartridge receptacle. In additional embodiments, the release devices may include an actuator or control mechanism 316, such as but not limited to, a button or other tactile means, for actuating the release device such that the removable memory cartridge 304 may be released or partially or substantially ejected from the stationary cartridge receptacle, and removed therefrom.
In some embodiments, a cost effective means for securing removable memory cartridges from counterfeit products may be desirable. In such embodiments, it would also be desirable that such means for securing removable memory cartridges does not alter the stored information or data format of the stored information in any manner. Additionally, such securing means can be designed to permit secure personalization so that third-parties can build data storage devices containing an OEM (original equipment manufacturer) secret without concern for the theft of that secret.
In one embodiment, the prevention of counterfeit removable memory cartridges can be accomplished by using a crypto-authentication system. For example, in one embodiment, the prevention of counterfeit removable memory cartridges can be accomplished by embedding, into the removable memory cartridges, authentication chips designed to securely authenticate them. Each chip, for example, may contain a preprogrammed serial number or other unique number, which is guaranteed to be unique or may otherwise be configured to particularly identify a removable memory cartridge or that a removable memory cartridge is not counterfeit. In one embodiment, the authentication chips may be the type of crypto-authentication devices manufactured by Atmel Corporation of San Jose, Calif., including the AT88SA102 family of chips.
As illustrated in
The authentication is cryptographically strong, and provides a cost effective solution to assure device authentication. The authentication is substantially transparent in operation, without interfering with operation of the hard drive or other removable data storage device.
This contrasts with other, less cost effective techniques, which may interfere with device operation, for example self-encrypting drives and other device implementations that can interfere with serial (or parallel) advanced technology attachment (SATA or ATA) and serial (or parallel) small computer system interface (SAS or SCSI) devices. Depending on application, the authentication system is also configurable to prevent access to unauthorized parties or unauthorized storage devices (cartridges), and to reduce security risks and malware exposure potential by preventing unauthorized replacement of hard drives and other removable storage media.
In one implementation, for example as shown in
Authentication device 305 may also be operable to calculate or determine secure hash algorithm (SHA) values, including, but not limited to, SHA-256 and other SHA family cryptographic hash function values. In these implementations, system security may utilize the ability of authentication device 305 to store a key, for example a unique, securely stored private key.
In one method of operation, a root key, such as a 256 bit random key created from a strong source of entropy, is stored in authentication device 305 of docking station 302, for example in a protected area of memory in authentication device 305. The root key can be concatenated with a unique HDD serial number or other medium identifier to generate a secure key, which is stored in authentication device 305 of data cartridge 304, for example in a read-only area of memory in authentication device 305. The root key and the secure key are utilized to authenticate data cartridge 304, as described below.
In operation of method 350 a root key is stored in the docking station authentication device (step 351), for example in a secure storage area, and a secure key is stored in the data cartridge authentication device (step 352), for example in a read only storage area. The authentication device on the data cartridge identifies the data cartridge to the authentication device on the docking station (step 353), for example by sending a unique serial number, drive characteristics, or a combination of such identification data.
The authentication device on the docking station concatenates the ID data with the root key (step 354), for example using a secure hashing algorithm such as SHA-256, or other cryptographic calculation, and transmits a random number, nonce, or other challenge information to the authentication device on the data cartridge (step 355). The authentication device on the data cartridge responds by concatenating the cartridge ID (or other results of identification, step 353) with the nonce (step 355) using a secure hash engine algorithm such as SHA-256, or other cryptographic calculation, and sends the results as a response to the authentication device on the docking station (step 357).
The authentication device on the docking station compares the nonce (or other challenge information) with the response from the authentication device on the data cartridge (step 358). If the results match, the data cartridge is authenticated (step 359A), and data communications with the host device are enabled (that is, authentication is successful). If the results do not match, the data cartridge is not authenticated (step 359B), and data communications with the host device are not enabled (that is, authentication fails).
Host system 320 may comprise a host computer, data processor, data storage system, or other computing or data processing apparatus configured for data communications with the media drive slot 318. The media drive slot 318 may be configured for a DVD, ODD, HDD, or other data storage medium or device, as described above, and the data cartridge 304 may be configured as a HDD, tape drive, optical disk, tape cartridge, flash drive, or other data storage medium.
In one particular embodiment, for the example, the media drive slot 318 may be provided as a DVD, ODD or other optical media drive slot (or expansion slot) configured for use with an optical data storage medium, and the removable data cartridge 304 may be configured as a hard disk drive, tape cartridge, or other magnetic data storage medium. Thus, docking station or sled 302 may function as a media drive adapter for use within media drive slot 318, as configured for a one type of data storage media. The media drive adapter is further configured to accept removable data cartridge 304, as configured for another, different type of data storage medium, and to place removable data cartridge 304 in data communication with host system 320 via media drive slot 318.
As shown in
The media drive adapter 302 also includes a media drive connector (e.g., connector 106 of
Depending on embodiment, the outer sides or housing 322 of the removable memory cartridge 304 may be variously configured to align or fit with the sides 324 of receiving bay 306 for receiving the cartridge 304 in the receptacle 302, for example with the cartridge 304 retained between the bottom 326 of the receiving bay 306 and a top or cross-member 328, as shown in
The stationary memory cartridge receptacle mechanism 302 of
The receptacle or docking station 302 provides a media drive connector 208 for communicatively coupling or connecting the receptacle 302 into a drive bay or media expansion slot on the host data storage system or host computer. A micro motor or motor assembly 332 (dashed lines) and a (e.g., small) gear reduction system 334 are coupled to a cam push lock or latch 336. The cam push lock 366 is able to eject the cartridge 304 to a precise location, for removal from receptacle 302 while receptacle 302 is positioned in the ODD bay or media expansion slot.
The motor assembly 332, reduction gearing 334, and cam push lock or latch 336 are operable based upon an eject command from the host system, for example as provided via connector 208. Alternatively, receptacle 302 may be configured for ejection and removal of cartridge 304 based on a direct user command, with or without an override based on the host system's prevent (or allow) eject status, as communicated over connector 208 or other command or data path. The direct user command may be provided by an external control feature 121, as described above, or based on a biasing switch device or other mechanism sensitive to a force or push on cartridge 304, and configured to trigger the ejection mechanism based on such an input.
As shown in
The mechanical isolation or damping members 344 may be positioned between the outer case 322 of data cartridge 304 and the inner sides 324 (and/or 326 and 328) of the drive bay 306, inside the docking station or media drive adapter 302. The shock absorbing, damping, anti-vibration and mechanical isolation characteristics of damping members 344 may be selected by utilizing a resilient material in construction, such as a rubber, plastic, polymer or composite material with suitable durability and mechanical damping properties. Thus, the mechanical isolation members 344 may form a resilient mechanical coupling between the data cartridge 304 and the media drive adapter 302 to suspend the data cartridge 304 within the drive bay 306.
As shown in
The suspension members 342 and mechanical isolation (or resilient damping) members 344 also allow the system 300 full use of the sway space inside the drive bay 306 of media drive adapter 302, substantially in or along the (e.g., flat) plane of the hard drive or other data cartridge 304. This distinguishes from the use of shock absorbing material or systems inside the cover 322 of the data cartridge 304, where placing material between the internal drive and the enclosure or cover 322 may reduce the overall available travel, as compared to the externally damped design of
By attaching suspension members 342 and/or motion isolation or bumper members 344 in the form of protrusions from the sides of outer housing 322 of the data cartridge 304, as shown in
The systems and methods for removable memory cartridges and docking stations compatible with different media drive slots, including a stationary cartridge receptacle and a removable memory cartridge, as disclosed herein enable a variety of benefits and advantages. As can be recognized from the foregoing, such benefits and advantages include, but are not limited to, persistent enumerations of a fixed drive letter or target, safe eject mechanisms and services that can prevent data loss, authentication of removable memory cartridge provenance, application of encrypted data storage elements such as those in accordance with the OPAL Storage Specifications, additional shock and drop protection for, for example, sensitive memory elements like HDDs, and spanning of multiple removable memory cartridges permitting expanded capacity.
For example, in traditional systems addressing the media slots wherein an optical drive slot is occupied by a HDD or solid-state memory module, which can be inserted, electrically coupled, mechanically retained, and ejected like an optical drive, each time the unit is inserted into the optical drive slot, a drive letter is assigned. As the same drive or numerous different drives are coupled and ejected from the drive slot, the drive letters are reassigned. Accordingly, there is no drive letter or device persistence. In contrast, because the systems disclosed herein include a stationary cartridge receptacle or stationary docking station that may be kept coupled with the drive slot, the systems disclosed herein permit drive letter or device persistence between the same or different removable memory cartridges/elements.
In the foregoing description, various embodiments of the present disclosure have been presented for the purpose of illustration and description.
