The field of the invention relates generally to data storage media, and more specifically, to housing solid state storage in tape cartridges.
Computer systems typically include a combination of software, such as programs and data, and hardware, such as semiconductors, transistors, chips, circuit boards, data storage media, and processors. An example of data storage media is magnetic tape. Typically magnetic tape is wound on a reel, which may be located within a portable cartridge. Another example of data storage media is solid state storage (SSS). Unlike magnetic tape which stores data magnetically, solid state storage stores data electronically.
According to embodiments of the invention, a tape cartridge adapted to house solid state storage may be provided. The cartridge may include a cartridge housing. The cartridge may also include a reel located within the cartridge housing, wherein the reel includes one or more radial grooves adapted to hold one or more solid state storage elements. According to other embodiments, the cartridge may also include one or more solid state storage elements held within the reel, wherein each solid state storage element includes a first electrical connector.
According to embodiments of the invention, a method of assembly of a tape cartridge adapted to house solid state storage may be provided. The method may include providing a reel adapted to hold one or more solid state storage elements. The method may also include placing one or more solid state storage elements within the reel, wherein each solid state storage element includes a first electrical connector. The method may also include placing the reel within a cartridge housing. According to other embodiments, the method may also include mating the cartridge housing to a cartridge receiver, wherein the cartridge receiver includes a second electrical connector adapted to electrically connect to the first electrical connector, and a mechanism adapted to rotate the reel.
Data storage cartridges, such as tape cartridges, typically include a type of data storage media, such as magnetic tape, and are usually inserted into a separate data storage drive so that data may be read from and/or written to the data storage medium. Such cartridges are convenient means of storing large quantities of data which are accessed occasionally. They are particularly useful in automated data storage libraries which can contain large numbers of the cartridges in a storage system. The storage library may also contain an automated retrieval system to access a cartridge when needed and deliver the cartridge to the data storage drive. Historically, these data storage libraries were developed with cartridges containing magnetic tape, since magnetic tape was the most economical data storage medium at the time. However, a disadvantage of magnetic tape is the linear fashion in which the tape is read from and written to, i.e. the tape must be wound back and forth to access different section of data. Other data storage medium, such as solid state storage, allow for quick read/write capability to the entire data storage. Due to advances in the technology of solid state storage, it has become economical to use solid state storage in place of magnetic tape. However, in the interest of continuing to utilize already existing data storage library structures, it may be desirable to adapt the same or similar cartridges which previously housed magnetic tape, to house solid state storage.
Embodiments of the invention provide a tape cartridge adapted to house solid state storage. The cartridge may include an upper and lower cartridge housing. The cartridge may contain a reel similar to a reel designed to hold magnetic tape. The reel may have a number of radial grooves or slots designed to hold a solid state storage element, such as a universal serial bus (USB) flash drive. Each solid state storage element may include an electrical connector protruding outward from the reel. The cartridge housing may also include a means to access the connectors of the solid state storage elements in order for an external electrical connector to be inserted into the cartridge and connected to the solid state storage elements. The reel may be rotated in order for all of the solid state storage elements within the reel to be accessed by the external electrical connector.
Referring to the drawings, wherein like numbers denote like parts throughout the several views,
Each set of grooves 114 may hold a solid state storage element 120. Each solid state storage element 120 may include an electrical connector 122. An example of a solid state storage element is a USB flash drive. Other examples of a solid state storage elements include NAND flash memory, read-only-memory (ROM), and electrically-erasable, programmable, read-only-memory (EEPROM). The elements 120 may be inserted into the grooves 114 of the reel 106 so that the connector 122 is directed away from the center of the reel 106. Each set of grooves 114 may contain a retention device (not shown), such as a clip or magnet, which may be disengaged in order to remove the solid state storage element 120. In various embodiments, a part of the retention device may be located on the reel 106 and a corresponding part may be on the solid state storage element 120. For example, if the retention device is two magnets, then one magnet may be located on the outer surface of the cylindrical core 108, and another magnet may be located on the surface of the solid state storage element 120 which faces the outer surface of the cylindrical core when the solid state storage element is placed into the grooves 114 of the reel 106. In other embodiments, the retention device may be a clip located on the outer surface of the cylindrical core 108, and a tab located on the surface of the solid state storage element 120 which faces the outer surface of the cylindrical core and engages the clip when the solid state storage element is placed into the grooves 114 of the reel 106.
The upper housing 102 may include an aperture 124 through which an external connector may be inserted in order to connect to the connector 122 of the solid state storage element 120. In various embodiments, the aperture 124 may be of large enough to facilitate the removal and replacement of the solids state storage element 120. In an assembled position, the reel 106 may include the ability to be rotated within the cartridge 100 by an external mechanism which enters the cartridge 100 through a hole 118 in the lower housing 104. By selectively rotating the reel 106, each solid state storage element 120 may be aligned with the aperture 124 so that an external connector may be connected to it. Each set of grooves 114 and each solid state storage element 120 may have a form of individual labeling, such as a barcode, to enable identification of each solid state storage element 120 and its location. A barcode may also be located on any surface of the reel 106, and each set of groves 114 may have its own barcode to enable identification. A barcode reader (not shown) may be located with the cartridge 100 or it may be located outside the cartridge 100 and read the barcodes through the aperture 124. The barcode may also serve to ensure proper alignment of the reel 106 so that each solid state storage element 120 may be properly accessed.
Block 304 may contain the operation of placing the reel within a cartridge housing. The cartridge housing may consist of an upper and lower housing such as the cartridge 100. The cartridge housing may have an aperture such as the aperture 124 located in a position so as to allow an external connector to enter the cartridge housing and connect to a connector of a solid state storage element positioned nearest to the aperture. In various embodiments, the method of assembly 300 may include inserting the cartridge into a cartridge receiver. The cartridge receiver may be the cartridge receiver 202. As previously mentioned, the cartridge receiver may have a recess which holds an electrical connector adapted to mate with the electrical connectors of the solid state storage elements.
Block 306 may contain the operation of placing one or more solid state storage elements within the reel. The solid state storage elements may be the solid state storage elements 120 or any other similar solid state storage element. Any number of solid state storage elements may be placed within the reel. Each solid state storage element may include an electrical connector such as the electrical connector 122. Examples of electrical connectors used in conjunction with solid state storage elements are USB 1, USB 2.0, and USB 3.0
