The present description is directed to moving a cartridge including a storage medium within a shuttle complex that includes numerous shuttle connections, and a plurality of library strings connected by at least one shuttle connection. Each shuttle connection has a car able to move within the shuttle connection and each library string has at least one cartridge including a storage medium. The shuttle complex identifies a library string that contains the access-cartridge (LSAC), identifies whether there is a drive within the LSAC that has a second cartridge mounted therein which comprises only inactive data chunks, removes the second cartridge from the drive within the LSAC if an elapsed time since the drive within the LSAC most recently accessed the second cartridge exceeds a predetermined time period threshold, and mounts the access-cartridge to the drive within the LSAC.

A method for the recognition of spatial proximity relationships in a modular system having module assemblies, each module assembly having a transmitter and a receiver arranged so that the transmitter of a first module assembly corresponds to the receiver of a second module assembly, and each of the module assemblies having a network connection for connection via a communication network to other of the module assemblies, includes: automatically requesting and allocating a network address for each of the respective network connections via the communication network so as to enable an addressing of the module assemblies via the network; and determining spatial proximity relationships of the module assemblies by triggering and evaluating the transmitters and receivers using the communication network via the network connection.

A computer-implemented method, according to one embodiment, includes: maintaining a reference count and an access count for each of a plurality of objects stored in an optical media storage system, using the reference count and access count to create a popularity metric for each of the plurality of objects, for each medium having one or more of the plurality of objects, creating a medium popularity metric based on the popularity metrics of the one or more objects on the respective medium, and using the medium popularity metric of each respective optical medium to arrange the optical media in the optical media storage system. Other systems, methods, and computer program products are described in additional embodiments.

A magazine management device stores a plurality of magazines in which a plurality of optical discs is housed. The magazine management device includes a case that supports the plurality of magazines, a plurality of partitions that divides the case so as to form a plurality of regions in which the magazines can be stored one by one, an antenna that transmits a radio wave for asking a radio identifier provided to the magazine for a response and receives a radio wave of the response transmitted from the radio identifier, and an arithmetic processor that receives information obtained from the radio wave of the response received by the antenna.

A computer-implemented method, according to one embodiment, includes: maintaining a reference count and an access count for each of a plurality of objects stored in an optical media storage system, using the reference count and access count to create a popularity metric for each of the plurality of objects, for each medium having one or more of the plurality of objects, creating a medium popularity metric based on the popularity metrics of the one or more objects on the respective medium, and using the medium popularity metric of each respective optical medium to arrange the optical media in the optical media storage system. Other systems, methods, and computer program products are described in additional embodiments.

A system and method for transporting one or more data storage cartridges between data storage library strings, including a plurality of data storage libraries, a plurality of shuttle connections coupled to the plurality of data storage libraries, and a plurality of shuttle cars movably housed within each of the plurality of shuttle connections. The system also includes at least one system controller, wherein the at least one system controller is configured to receive host commands and control movement of the shuttle cars between the plurality of data storage libraries, and the at least one system controller is configured to control movement of each of the shuttle cars such that at least one shuttle car is associated with each of the plurality of data storage libraries during operation of the system.

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.

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.

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 such that each predetermined selected demount position is stored in a lookup table of predetermined selected demount positions for a subsequent demount operation. The idle time of the accessor during a demount operation may be reduced.
