摘要:
A library manager to determine a relay-point library string when a particular cartridge (specific cartridge) is moved to an empty drive (target drive) for mounting. A method for determining a relay-point library string includes: receiving a command to mount a cartridge in a library string located on one side of the relay-point library string; searching for the target drive among library strings, and finding the target drive in a library string on the other side of an interposed relay-point library string relative to the library string in which the specific cartridge is located; selecting a relay-point library string based on predetermined conditions to move the specific cartridge using shuttle connections to the found target drive; and searching to determine whether or there is a newly available drive in a relay-point library string other than the selected relay-point library string before the selected cartridge reaches the selected relay-point library string.

A method for preventing overwriting of data, e.g., on a magnetic medium, includes receiving a write command to write to a magnetic tape. A determination is made as to whether a current location of the magnetic tape is at a block at a beginning of tape. A determination is also made as to whether data corresponding to the write command is at least one of: a size and type specified for the block. Execution of the write command is disallowed when the data corresponding to the write command is not of the specified size and/or type.

Provided is a medium delivery control apparatus that can prevent the wear of a means relating to the delivery of a recording medium and extend the life of the delivery means. The medium delivery control device controls a medium delivery means for connecting, disconnecting and delivering the recording medium with respect to a deep cell, and includes a first detection recording means for detecting and recording the storage or non-storage of the recording media and the identity of the recording media being stored for each deep cell, a second detection recording means for detecting and recording the number of insertions and removals of the recording medium for each deep cell, a storage point candidate searching means for searching for a storage point candidate cell on the basis of the recording of the first detection recording means, a number-retrieval determining means for retrieving the number of insertions and removals of the recording media at the retrieved storage point candidate cell and determining whether the number exceeds a threshold on the basis of the recording of the second detection recording means, and a medium-delivery control means for controlling the medium delivery means such that the recording medium is delivered to the retrieved storage point candidate cell if the threshold is not exceeded.

摘要:
A library device comprises a cell, a drive, and an accessor. The cell is capable of accommodating a plurality of cartridges. The drive performs a recording or reproduction of data between the cartridges and the drive. The accessor carries the cartridges between the cell and the drive. The cell is provided with a first rack gear which extends in a direction in which the accommodated cartridges are arranged. The accessor comprises an accessor base and a feed block. The accessor base comprises a second rack gear. The second rack gear extends in the extension direction of the first rack gear. The second rack gear is formed in correspondence with the first rack gear. The feed block comprises a pinion gear, a driving unit, and a holding unit. The pinion gear is meshed with the first and second rack gears. The driving unit drives the pinion gear. The holding unit holds the cartridges.

Provided is a method of removing a cartridge, that is to be removed, that is housed in a deep side of a cell and stuck on a wall surface of the cell without increasing the number of components. In order to remove the cartridge stuck on the wall surface of the cell, the method includes a pressing step and a releasing step. In the pressing step, a picker mechanism is abutted on a latch lever, and then moved so as to move the latch lever from an engaged position to a released position. This presses the latch lever to increase the urging force of the urging unit. In the releasing step, after the pressing step, the picker mechanism is moved away from the cell to release the urging force of the latch lever spring.

Calibration of an automated data storage library having a plurality of storage slots configured to store at least one data storage cartridge. An element is placed in one of the plurality of storage slots having a known location, the element having similar external dimensions as a data storage cartridge having a fiducial mark thereon. The fiducial mark is sensed, and the position of the fiducial mark is calibrated with respect to the known location of the storage slot. The element comprises an exterior shell having similar external dimensions as a data storage cartridge; and the fiducial mark located on the exterior shell comprises at least one contrasting edge defining a specific calibration location on the element.

A media cartridge autoloader is disclosed which includes a main module including a media cartridge picker that pulls in a media cartridge via a mail slot and ejects the media cartridge via the mail slot. A media drive selectively receives the media cartridge. First and second media cartridge transport magazines transportably store the media cartridge. The main module further includes a stopper mechanism that inhibits the media cartridge from being fully reinserted when inserting the media cartridge is attempted in a state where the media cartridge has been ejected so as to at least partially protrude outside of the mail slot. The stopper mechanism contacts a lower part of a rear side of the media cartridge to stop the media cartridge in a state where a front side of the media cartridge is at least partially ejected through the mail slot.

There is disclosed a media cartridge autoloader. The media cartridge autoloader includes at least one mail slot through which a media cartridge is inserted and ejected, at least one media drive into which the media cartridge is loaded, at least one media cartridge storage section that stores the media cartridge, and a media cartridge picker. The media cartridge picker includes a turntable that supports the media cartridge and rotates to change the orientation of the media cartridge, a turntable rotating mechanism that rotates the turntable, and a media cartridge transporter that transports the media cartridge between the turntable and one of the mail slot, the media drive and the cartridge storage section. The turntable is provided with a media cartridge stopper member that stops the media cartridge inserted manually from the mail slot.
