Description

FIELD OF THE INVENTION

[0002] The present invention generally relates to digital information storage systems, and more particularly to a disk drive interface.

BACKGROUND OF THE INVENTION

[0003] Optical storage media such as compact disks (CDs), read-only memory compact disks (CD-ROMs), and digital versatile disks (DVDs) have become an information storage standard for personal computer information handling systems. Thus, most personal computers are provided with a CD-ROM or DVD drive for reading compact disks or DVDs. When a CD-ROM drive or DVD drive has not been integrated within a personal computer, an external CD rewritable (RW) drive is typically used as a peripheral device to a personal computer to provide storage and retrieval of data to/from optical storage media.

[0004] However, rapid technological advances have continually produced optical storage media drives, internal and external, having increased operating speeds and improved features, and it appears likely that this trend will continue. As a result, older and slower CD-ROM drives rapidly become obsolete when personal computer users purchase newer and faster CD-ROM drives, thereby causing a surplus of older and slower drives to accumulate. The same trend is certain to occur for digital versatile disk drives and for other optical storage media drives.

SUMMARY OF THE INVENTION

[0005] Accordingly, the present invention is directed to an interface for a disk drive. In one embodiment of the invention, the interface may be an adapter for providing stand-alone use of an optical storage media drive such as a compact disk or digital versatile disk. The adapter may receive an optical storage media drive that was originally designed for operation in conjunction with a computer system wherein the computer system controls the operation of the drive. However, instead of being utilized in conjunction with a computer system, the optical storage media drive is utilized in conjunction with the adapter of the present invention wherein the adapter controls operation of the drive. The adapter and the optical storage media drive, in combination, provide a system which is capable of reading and playing optical media independently from the computer system. Such an adapter comprises a housing for receiving the optical storage media drive and a circuit disposed within the housing for interfacing with the optical storage media drive wherein the optical storage media drive may read an optical storage medium completely independent of the computer system.

[0006] In a second aspect of the present invention, an interface may be provided for an external optical storage media drive to provide direct data transfer from a storage media to optical disk. According to an embodiment of the invention, an interface may be in the form of a data port that allows coupling of storage media to the external optical storage media drive. Instruction included within the interface of the present invention may enable direct data transfer from flash memory to an optical disk inserted within the optical storage media drive. In alternative embodiments of the present invention, a data port interface of the present invention may be fitted within a receptacle for housing a conventional external optical storage media drive or may be may manufactured within a stand-alone external optical storage media drive.

[0007] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention as claimed.

[0008] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate an embodiment of the invention and together with the general description, serve to explain the principles of the invention.

DETAILED DESCRIPTION

[0022] Reference will now be made in detail to the presently preferred embodiment of the invention, an example of which is illustrated in the accompanying drawings.

[0023] Referring now to FIG. 1, an illustration of an optical media drive such as a CD-ROM or DVD drive utilized in a personal computer system is shown. The personal computer system 100 generally comprises a housing 102 that contains the electronic components of the computer system. The housing 102 provides a series of drive bays 104 in which peripheral storage media drives (106, 116) may be installed such as an optical storage media drive 106 and floppy disk drive 108. The computer system 100 further comprises a display device 110, keyboard 112 and graphical input device 114. The optical storage media drive 106 is typically provided with the personal computer system 100 for reading computer readable data encoded on an optical storage media such as a compact disk. A compact disk (CD) is storage medium having a plastic substrate embossed with a pattern of pits that encode signals (e.g., audio or data) in an optically readable digital format. The disk is coated with a metallic layer to enhance its reflectivity and is read in an optical storage media drive or CD player that reflects a laser beam off of the disk as it rotates and detects fluctuations of the reflected intensity due to the presence or absence of the pits.

[0024] Referring now to FIG. 2, the replacement of the optical storage media drive of FIG. 1 with an advanced optical storage media drive is shown. A typical optical storage media drive 106 is constructed to have a size and shape to fit into a standard sized drive bay 118 found in most personal computers. The housing 102 of the computer system 100 is designed to modularly receive a number of peripheral storage media such as hard disks, floppy disks, optical storage media drives, PC-CARD drives, etc. such that the user may install a particular combination of storage media drives as desired. As faster and more advanced optical storage media drives are developed, the user may replace the old optical storage media 106 drive with a newer model drive 116. Since the housing 102 of the computer is designed to be modular, replacing an old optical storage media drive 106 merely involves disconnecting the internal cabling and unfastening the drive from the housing, and then connecting the new drive 116 to the same cabling and installing the new drive in the same drive bay 118.

[0025] Referring now to FIG. 3 an adapter designed to receive an optical storage media drive in accordance with the present invention will be described. The adapter 200 as shown in FIG. 3 is designed to receive an optical storage media drive 106. The adapter 200 provides a housing 202 having a bay 204 similar to the bay 118 of the computer housing 102.

[0026] The bay 204 of the housing 202 includes a connector 206 for electrically connecting the adapter 200 with the optical storage media drive 106. Bay 204 may include an additional connector 208 for supplying operational power from the adapter 200 to the optical storage media drive 106, for example. Connector 244 receives the audio output signal (left and right channel signals) from drive 106. Connectors 206, 208 and 244 preferably facilitate rapid connection to optical storage media drive 106 which is inserted and fastened into bay 204. Adapter 200 includes a display 210 for displaying operational information such as track selection, program length, etc. of the material recorded on an optical storage disk inserted into the optical storage media drive 106. The display may also display related information such as the last selected command (e.g., play, pause, stop), for example.

[0027] In an alternative embodiment, the display 210 may be of sufficient size and construction to allow the full screen viewing of video in the case where the drive 106 is a DVD or similar type of video drive wherein the video output of the drive is capable of being displayed on the display 210. Adapter 200 further includes user interface and control buttons 212, 214 and 216 for controlling the operation of adapter 200 and optical storage media drive 106. Adapter 200 may include a volume control 218, line level output jacks 222, and an on-off switch 220. Adapter 200 further provides a power jack 224 for receiving power from an external power supply 228 having an appropriate plug 230 for mating with jack 224. Adapter 200 also provides an audio output jack 236 providing an output signal for driving a pair of headphones 232 or external speakers 238, each of which having an appropriate plug 234 and 238 for mating with jack 236. The speakers may be driven by the output signal provided by jack 236, or the speakers may contain a separate amplifier amplifying the output signal of the jack 236 to a greater level. Additionally, adapter 200 may include a digital output jack 432 for supplying a digital signal to an external device such as a receiver or amplifier capable of receiving a digital signal to maintain signal fidelity. The digital signal provided at jack 432 may be electronic or optical and may include data, audio or video information. Adapter 200 may include a handle 240 which may be positioned to facilitate carrying of the adapter 200 by hand or function as a stand when placed on a surface to provide stability.

[0028] Referring now to FIGS. 4A-C, top, bottom and side elevations of the adapter of the present invention are shown. The top view of 4A illustrates the display 210 and user interface keys 212, 214 and 216. Button 212 may be designated to control opening or closing the disk tray (not shown) of the optical storage media drive for inserting and removing optical storage media (e.g., compact disks). Program select keys 214 are included to control and select program information for a compact disk inserted into the optical storage media drive. Control keys 216 provide play control functions for the playing of a particular track on the compact disk, for example play, pause, stop, search forward, search reverse, etc.

[0029] FIG. 4B illustrates in further detail the control and interface features of the adapter 200. A volume control 218 controls the playback amplitude level of the compact disk selection. Output jacks 222 provide a line level output signal for driving an external device such as a preamplifier, surround sound processor, receiver, etc., and may be RCA-type jacks, for example. On/off switch 220 connects or disconnects power from the internal components of the adapter 200 and optical storage media drive 106. Jack 226 provides a signal for driving a pair of headphones or small speakers, and may be a suitable standard ⅛ inch jack. Power jack 224 receives power from an external power supply which converts ac power into dc power. The digital output jack 432 provides a digital output signal for connection to an external digital device. A strap or loop 246 may be provided for facilitating carrying of the adapter, for example by passing the user's belt through loop 246.

[0030] FIG. 4C shows a bottom view of the adapter 200. A battery compartment 242 may be included to provide operational power from batteries during portable use.

[0031] Referring now to FIG. 5, a block diagram of the system of a typical optical storage media drive is shown.

System 300 also includes a microcontroller 304, servo control circuit 306, RF amplifier and EFM (eight-to-fourteen modulation) demodulator 308, and a processor which is typically a digital signal processor 310. Digital signal processor 310 may be utilized to decode the information stored on the optical storage media (not shown) inserted in drive 106.

[0032] System 300 may also include a digital to analog converter 312 and low pass filter (LPF) 314 for providing an analog output signal 316. Further, system 300 includes an interface controller 318 for providing integrated drive electronics/AT attachment (IDE/ATA) or small system computer interface (SCSI) or the like control of the optical interface controller 318 through digital control 320 from a host computer (not shown) in which the optical storage media drive is utilized (‘AT’ refers to the architecture of a specific model of personal computers (PC) known as the PC-AT introduced by International Business Machines Corporation circa 1984 adopted as an industry standard and being synonymous with personal computers having an industry standard architecture (ISA) bus. Digital control 320 may be data, control, address, audio or video signals, for example. Further, a memory 322 is provided which may be a random access memory for storing executable instructions of digital signal processor 310 or as a data buffer, for example. Normally, the optical storage media drive is utilized in a host computer system such as computer system 100 of FIG. 1 wherein operation of the optical storage media drive is controlled by the computer system including providing operational power thereto. The adapter components of the present invention, as discussed in further detail with respect to FIG. 6, provide operation and control functions of the optical storage media drive in lieu of computer system 100. When optical storage media drive 300 is installed in bay 204 of adapter 200 shown in FIG. 3, connector 244 receives analog output signal 316 of drive 300, and connector 206 couples with digital control 320.

[0033] Referring now to FIG. 6, a block diagram of the circuitry of the adapter of the present invention is shown.

[0034] A filter 410, such as a low pass filter, may be included to filter the output signal from the optical storage media drive which may be optionally bypassed 412. A user interface 414 allows for the user to control the playback functions of the optical storage media drive. User interface 414 may include control circuits (not shown) in conjunction with buttons 212, 214216 and display 210 of FIG. 4A to control the operation of the optical storage media drive 106 of FIG. 3. Power may be supplied to the adapter components 200 and to the optical storage media drive from a battery 420 or from an external power supply 422. A regulator 418 may be further included with the adapter components 200 to provide regulated power and may provide voltage or current regulation or a combination thereof.

[0035] A power amplifier 426 may be included in the adapter 400 for providing a signal of sufficient magnitude to drive one or more speakers 236. Alternatively, one or more speakers 236 may be included within the adapter 400 such that external speakers would not be required. A line level preamplifier 428 may be included to provide a line level output 222 to an external device such as an amplifier or sound processor (not shown). Interface circuit 430 may provide a digital output signal at jack 432. The digital signal may be electronic or optical and may be audio, video or combined signal.

[0036] Alternatively, output jack 432 may provide an analog video output signal through appropriate modification of interface circuit 430 in the case where an analog video output signal is desired. The analog video output signal may be an RF modulated or base band composite video output signal for driving the input of an appropriate video device such as a television, VCR or camcorder, etc., which in conjunction with audio outputs 222 provides combined video and audio playback of an appropriate optical storage disk (e.g., DVD). Thus, system 300 of FIG. 5 and the adapter circuit components 200 of FIG. 6 together provide a system which is capable of playing appropriately formatted optical storage media as a stand-alone unit.

[0050] It is contemplated that many forms of compact flash are not readable without the use of an additional adapter device. However, compact flash memory 1110 may include a compact flash memory storage coupled with an adapter, the adapter being coupled to the external optical storage media drive 900 via a data port of the present invention.

[0051] Referring to FIG. 12, a flow diagram representing a process 1200 for copying data from a storage media to an optical disk in accordance with the present invention is shown. Execution of process 1200 may be implemented by the optical storage media drive 910 of FIG. 9 and receptacle assembly 1000 of FIG. 10. Steps of process 1200 may be in the form of a program of instructions through a software, hardware, or firmware implementation. Process 1200 may begin upon the receipt of a connector within a data port of an optical storage media drive of the present invention 1210. According to a wireless implementation, the process 1200 may begin upon the enablement of a wireless connection between the storage media and the optical storage media drive of the present invention.

[0052] The next step may be the verification of the presence of an optical disk within the optical storage media drive 1220. If an optical disk is not present within the drive of the optical storage media drive, an alert to a user may be initiated 1230. Alternatively, the disk drive may open to allow insertion of a disk and to signal to the user that an optical disk is necessary.

[0053] Upon the receipt of an optical disk 1240 and/or a verification of the presence of an optical disk 1220, a determination of an amount of space occupied by the desired amount of data for copying within the storage device may be completed 1250. A determination of whether the amount of available storage space on the current optical disk within the optical storage media drive may support the desired amount of data for copying from the storage media be completed 1260. If the available storage space on an optical disk will not support a desired data transfer, an alert may be provided to a user that one or more additional optical disks may be required to support the desired transfer

[0054] If the optical disk has enough storage space to support copying of the desired amount of data, the desired amount of data may be copied to optical disk 1280.

[0055] An advantageous aspect of the external optical storage media drive 900 and process 1200 of the present invention is the direct copying of data from a storage media to an optical storage disk within an external optical storage media drive 900 of the present invention. Direct copying may refer to data transferred from a first device, for example a storage media, to a second device, such as an optical storage disk, without passing through a computer or requiring resources of a computer to control the data transfer. Advantageously, data may be copied to an optical storage disk by an external optical storage media drive 900, the external optical storage media drive 900 being uncoupled to a computer. Thus, copying of data may be executed without requiring processing support of a computer.

[0056] It is believed that the present invention and many of its attendant advantages will be understood by the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the components thereof without departing from the scope and spirit of the invention or without sacrificing all of its material advantages. The form herein before described being merely an explanatory embodiment thereof. It is the intention of the following claims to encompass and include such changes.
