On-cartridge encryption key storage for cartridge-based library
A secure cartridge-based storage system includes a set of read/write control electronics on a control board adapted to removably couple with each of a plurality of storage cartridges. The read/write control electronics are adapted to transmit a public key to a target storage cartridge in response to a read/write command received from a host device. The target storage cartridge includes and encryption circuit that authenticates the transmitted public key against a stored public key, accesses a locally-stored encryption key responsive to successful authentication of the public key; and utilizes the locally-stored encryption key to encrypt or decrypt data of the read/write command that is in transit between the storage media and the control board.
Reservation-based management of movable components
Techniques for management of movable devices are disclosed. A system receives a request for an operation associated with a position on a rail. The system selects a component on the rail to execute the operation. The system identifies a rail segment that extends from the component's initial position to the position associated with the operation. The system requests a reservation of that rail segment. If the reservation is obtained, then the system applies electrical signals to move the component along the rails segment to the rail position associated with the operation. The system may also identify one or more other components, physical cells, etc. to reserve, in order to complete the operation.

Robotic confirmation of column straightness
A computer-implemented method includes identifying a lower calibration target of a column of an automated tape library and identifying an upper calibration target of the column. The method includes calculating at least one slot position between the upper calibration target and the lower calibration target. For at least some of the calculated slot positions, the method includes performing a check including identifying an actual slot position corresponding to the calculated slot position. The actual slot position is located by a robotic accessor. The method includes comparing the calculated slot position to the corresponding identified actual slot position and determining whether the calculated slot position is within a predefined range of the corresponding identified actual slot position. The method includes outputting a result of the determination.
DATA STORAGE LIBRARY WITH MEDIA ACCLIMATION DEVICE AND METHODS OF ACCLIMATING DATA STORAGE MEDIA
A system, method and apparatus to acclimate a data storage component from a first environmental setting to a second environmental setting is disclosed. In one embodiment a system having a data storage library with a plurality of data storage cartridges and at least one media acclimation device having one or more storage locations which are sized to accept one or more data storage cartridges therein is disclosed. The at least one media acclimation device is configured to gradually acclimate the one or more storage locations from an external environmental condition to an internal environmental condition. In another embodiment, a method of acclimating a data storage library component is disclosed. The system, method and apparatus may optionally further include at least one environmental conditioning unit for conditioning the internal environment within the library.

Predetermined placement for tape cartridges in an automated data storage library
Embodiments for predetermining optimal demount position for demounting data storage cartridges in an automated data storage library by a processor. A selected demount position may be predetermined, while performing one of a plurality of robotic movements by an accessor, for each mounted data storage cartridge for demounting data storage cartridges in the automated data storage library. The selected demount position is recalculated for each mounted data storage cartridge for demounting the data storage cartridges while performing a subsequent demount operation, where the selected demount position is determined according to the recalculation prior to a demount command being issued. Accordingly, the idle time of the accessor during a demount operation may be reduced.

Disk cartridge data storage library
A data storage disk cartridge library includes a media drive having a clean internal environment, a disk cartridge bay positioned adjacent to the media drive, and a disk cartridge positioned in the disk cartridge bay and having clean compartments for housing a clean disk trays supporting clean magnetic recording disk media. The media drive has a disk tray extractor including a seal plate positioned at times flush with a surrounding shroud, and a set of pins for extending through the seal plate and a disk tray and for moving to a tray locking position. The seal plate covers a disk tray faceplate to physically isolate the faceplate from the clean portion of the disk tray, the corresponding clean compartment, and the clean environment of the media drive. The shroud is configured to cover surfaces of the disk cartridge adjacent to the faceplate.
