A library device includes: a housing for accommodating a magazine to be able to be put in and out, wherein the magazine has slots for accommodating recording medium cartridges to be able to be put in and out; an accessor for conveying the recording medium cartridge ejected from the slot to the magnetic tape drive; and a cartridge jump-out preventing mechanism for preventing the recording medium cartridge from jumping out to a moving path of the accessor. The cartridge jump-out preventing mechanism includes: an elastic pushing mechanism which can push the recording medium cartridge into the slot by using an elastic force when the magazine is inserted into the housing; and a latch mechanism which can hold the recording medium cartridge so that the recording medium cartridge does not jump out of the slot when the recording medium cartridge is completely accommodated in the slot.

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.

Utilities (e.g., systems, apparatuses, methods) that reduce robotic assembly contention in media element storage libraries by translating (e.g., displacing) a robot arm of a first robotic assembly mounted over a first storage array of a storage library away from a central reference plane as the robot arm is being pivoted into a first position adjacent the first storage array to allow a robot arm of a second robotic assembly to slide or otherwise move past the robot arm of the first robotic assembly, even when the robot arms of the first and second robot arms are disposed at the same height (e.g., along a z-axis) within the storage library. For instance, a pivot member of the robot arm may be mounted on a carriage that is configured to translate between the first and second storage arrays in response to the pivot member being pivoted about a pivot axis.

A multi-rack assembly with an inter-rack gear track system comprising a first rack, a second rack, and at least one intermediate rack positioned between the first and second racks and releasably interconnectable with each other. A segmented gear track extends from the first rack to the second rack. A compression segment is slidably coupled to the first rack and positioned against a biasing member. A clamping segment is slidably coupled to the second rack, and an intermediate segment is slidably coupled to the intermediate rack. A clamping mechanism moves the clamping segment against the intermediate segment forcing the compression segment against the biasing member and clamping the compression segment, the intermediate segment, and clamping segments together.

A disc device according to the present disclosure is a disc device for supplying a disc to each of a plurality of disc drives, and includes a carrier for retaining a plurality of discs in a stacked state, for separating one disc from the retained plurality of discs above a tray that is ejected from an arbitrary disc drive, and for placing the separated one disc on the tray. The carrier includes a first support claw that is capable of moving forward and backward below the plurality of discs, a second support claw that is capable of moving forward and backward into and out of a gap between a bottom disc and a disc that is adjacent to the bottom disc, among the plurality of discs, and a separation claw that is capable of moving forward and backward into and out of the gap and of pushing the bottom disc downward, where the bottom disc is separated from the retained plurality of discs by moving the first support claw, the second support claw, and the separation claw forward and backward, and pushing the bottom disc downward by the separation claw.

An apparatus includes one or more disc media cassettes configured to store multiple disc-based media. Multiple disc drives are configured to read and write data to the multiple disc-based media. A robotic delivery device is configured to transport a selected disc-based media to and from at least one disc drive of the multiple disc drives, and to transport the selected disc-based media directly to a spindle on the at least one disc drive.

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.

An apparatus includes a first jaw device, a second jaw device, and a disc sensor configured to sense presence of a storage disc between the first jaw device and the second jaw device. The first jaw device and the second jaw device form a gripper device configured to clamp a particular portion of a storage disc including an arc segment along an outer edge of adjacent surfaces of the storage disc.

A library system includes a plurality of drive modules for reading and writing storage media, typically magnetic tapes. The library system includes: (i) a picker for loading and unloading cartridges into, and out of, the drive modules; and/or (ii) a label printing drive integrated into the library system. The label printing drive receives a cartridge in the same way any of the drive modules receives a cartridge. The picker loads the cartridge in an identical way as the other drive modules and the label printing drive.

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.
