Abstract: The present invention provides an apparatus and methodology that allows a host computer to control a data storage device that is remotely located relative to the host computer utilizing the same software that is used to control data storage devices that are locally or directly connected to the host computer. In one embodiment, a host computer is provided that includes a virtual adapter that is capable of converting unencoded SCSI command related information from an operating system into encoded SCSI command related information that is capable of being transmitted over a network to a remotely located SCSI data storage device, i.e., a SCSI data storage device that is separated from the host computer by more than the distance set forth in the SCSI specification. The virtual adapter is also capable of decoding encoded SCSI command related information received from a remotely located SCSI data storage device into unencoded SCSI command related information that is suitable for processing by the operating system.

Abstract: The present invention provides an architecture for a data cartridge library that has a high data density footprint, i.e., is capable of storing data cartridges such that the density of data stored per area of floor space is high. In one embodiment, the architecture includes a plurality of shelves with each shelf capable of holding at least one data cartridge drawer that holds cartridges such that the face of the cartridges stored therein are substantially parallel to a side of the library.

Abstract: The present invention is directed to a data cartridge library system that realizes a reduced cost by reducing the number of certain components, especially expensive components, that are needed to perform certain functions within the library. With respect to certain functions, a reduced cost is realized by using lower precision compenentry in combination with componentry that compensates for lower precision while still providing a reduced component cost with respect to a given function. In one embodiment of the invention, a data cartridge picker is provided that: (1) uses a single electro-mechanical device for the functions of grasping a data cartridge, retracting a grasped cartridge from a drive/storage location, inserting a grasped cartridge into a drive/storage location, and releasing a grasped cartridge once position in a desired location; (2) is capable of compensating for variations in cartridge positioning; (3) has a gripping mechanism that.

Abstract: The present invention provides a data cartridge holder that is capable of accommodating a plurality of 8 mm tape cartridge. The holder includes retaining structure for engaging a discontinuity located between the door and the side of an 8 mm cartridge to retain the cartridge in the holder. Also included in the holder are orientation structure that inhibit the insertion of an incorrectly oriented 8 mm cartridge into the holder. The cartridge holder further includes a mounting structure that permits the holder to be removably mounted in a tape library. A dust cover is also provided that can be attached to the holder when, for example, the holder is mounted in a tape library and thereby prevent the dust cover from being lost or misplaced.

Abstract: The present invention provides an apparatus and method for monitoring the read/write reliability of data storage devices contained within a data cartridge library system. The data cartridge library system includes multiple player/recorder devices. In accordance with one aspect of the invention, the data cartridge library computer queries a player/recorder device after it has been involved in a read/write operation. In one embodiment, the information queried is the Write and/or Read ECC Error Rates. In another embodiment, the Write and/or Read ECC Error Rates are assessed to determine whether the subject player/recorder device is experiencing read/write problems and whether remedial action is warranted. In another embodiment, the subject player/recorder device is tested using a certified test cartridge and a known data pattern.
