A disk magazine according to the present disclosure is a disk magazine equipped with a resin-made disk tray that houses a plurality of disks in a stacked state and a tray holder that houses the disk tray. An opening is provided on one side surface of the tray holder so that the disk tray can be inserted into and extracted from the opening. A sliding member is mounted to a front wall of the disk tray so as to protrude more upward than a top surface of the disk tray. The front wall serves as a side where the disk tray is inserted into the opening. The sliding member is constituted of a resin material different from a resin material that constitutes the disk tray.

Utilities (e.g., systems, apparatuses, methods) that reduce robotic assembly contention in media element storage libraries by rotating (e.g., flipping, swinging, etc.) a robot arm of a first robotic assembly mounted over a first of first and second spaced storage arrays in a storage library into a first position between the first storage array and a central reference plane disposed between and parallel to the first and second storage arrays to allow a robot arm of a second robotic assembly to slide or otherwise move past the robot arm of the first robotic assembly (e.g., in a direction along or parallel to an x-axis parallel to the first and second storage arrays), even when the robot arms of the first and second robotic assemblies are disposed at the same height (e.g., along a z-axis that is perpendicular to the x-axis) within the storage library.

A data storage library system includes a first data storage library and a second data storage library, and at least one pass-through mechanism coupling the first data storage library to the second data storage library, wherein the at least one pass-through mechanism is configured to enable data storage cartridges to be transported between the first data storage library and the second data storage library. The environmental conditions within the first data storage library are controllable to maintain operational conditions conducive to at least one of reading and writing of data on a plurality of data storage cartridges. The environmental conditions within the second data storage library are controllable so as to gradually transition the environmental conditions between ambient environmental conditions and operational conditions within the first data storage library. Associated methods for transporting components between the first and second data storage libraries are disclosed.

An optical disc apparatus includes: a controller configured to acquire information of an access result and access positions on an optical disc when an optical disc drive unit configured to optically access an optical disc optically accesses the optical disc; and a storage configured to store the information acquired by the controller.

A disc tray includes a bottom wall including an outer periphery and an inner rib supporter supporting the lowermost disc from below. The bottom wall is thickened from the outer periphery toward the inner rib supporter. The lowermost disc includes a data recording area, an inner rib, and an outer rib. When the lowermost disc is stationary, the outer rib of the lowermost disc and the upper surface of the bottom wall are separated by a gap. When the lowermost disc is inclined in such a manner that part of the outer rib of the lowermost disc comes into contact with the upper surface of the bottom wall, the data recording area of the lowermost disc and the upper surface of the bottom wall are separated by a gap greater than thickness of the outer or inner rib.

The present disclosure relates to a storage and transfer apparatus for mass transfer of a plurality of data discs to trays of a plurality stacked disc drives. The storage and transfer apparatus may store a plurality of discs with the disc hold pins retracted and the telescopic sections collapsed over each other. In such a configuration, the stored discs may lie in contact with each other. The storage and transfer apparatus may transfer the plurality of discs to the trays of the plurality of stacked disc drives with the discs holding pins extended and the telescopic sections extended relative to each other.

A disc cassette includes a curved portion configured to hold multiple discs. A platform portion abuts the curved portion. A movable bale is configured to maintain discs securely in the disc cassette except when rotated off the discs.

Embodiments disclosed herein provide systems, methods, and computer readable media to handle unsuccessful movements of removable storage media in an automated removable media system. In a particular embodiment, a method provides receiving one or more user provided parameters that indicate one or more types of unsuccessful media move operations that should be reported as successful. The method further provides receiving a first request to move a first item of removable storage media from a first position in the automated removable media system to a second position in the automated removable media system and initiating a first move operation of the first item from the first position to the second position by at least one changer device. The method then provides determining that the first move operation resulted in one of the one or more types of unsuccessful media move operations and indicating that the first move operation was successful in response to the first request.

Utilities (e.g., systems, apparatuses, methods) that reduce robotic assembly contention in media element storage libraries by rotating (e.g., flipping, swinging, etc.) a robot arm of a first robotic assembly mounted over a first of first and second spaced storage arrays in a storage library into a first position between the first storage array and a central reference plane disposed between and parallel to the first and second storage arrays to allow a robot arm of a second robotic assembly to slide or otherwise move past the robot arm of the first robotic assembly (e.g., in a direction along or parallel to an x-axis parallel to the first and second storage arrays), even when the robot arms of the first and second robotic assemblies are disposed at the same height (e.g., along a z-axis that is perpendicular to the x-axis) within the storage library.

Embodiments of the present invention provide a drive storage system, method, and computer program process for automatically replacing drives. In one embodiment, one or more computer processors receive a request for a new drive. One or more computer processors direct an exchange robot to obtain the new drive from a drive repository and to proceed to a location of a used drive. One or more computer processors then direct the exchange robot to remove the used drive from the location and to insert the new drive into the location of the used drive.
