A disc grabbing device including a body, a drive shaft, a first cam, a second cam, multiple first movable parts and multiple second movable parts are provided. The drive shaft is rotatably disposed in the body. A first cam and a second cam are disposed on the drive shaft, and rotate together with the drive shaft. The first movable parts are disposed in the body and correspond to the first cam, and move to a disc hold position or a disc release position along with the rotation of the first cam. The second movable parts are disposed in the body and correspond to the second cam, and move to a disc release position or a disc hold position along with the rotation of the second cam.

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.

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.

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.

A disc device of the present disclosure includes a plurality of magazine units aligned in height direction of the disc device. Each of the magazine units includes a plurality of magazine holders each storing at least one magazine, a rail that is slidable in depth direction of the disc device along a side of a housing of the disc device and has higher stiffness than the magazine holders, and a box-shaped handle mounted to a front end of the rail to extend in width direction of the disc device. The plurality of magazine holders is arranged in depth direction of the disc device. The rail holds the plurality of magazine holders at one side of the magazine holder. The handle extends from the front end of the rail toward a free-end side of the magazine holders and includes a recessed engagement portion that admits a finger in depth direction of the disc device and enables the finger to engage when each of the magazine units is pulled out in depth direction of the disc device.

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.

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.

A conventional checking methodin which all of the optical disks are selected one by one from the plurality of optical disks stacked in a thickness direction and accommodated in a magazinetakes lots of time for checking. To solve the problem above, the optical disk device has a magazine, a disk drive, and a disk carrier device. The magazine accommodates a plurality of optical disks stacked in the thickness direction of the optical disks. The disk drive checks at least a recording surface facing an inner wall of the magazine of any optical disk of the optical disks accommodated in the magazine. Of the plurality of optical disks stacked and accommodated in the magazine, the disk carrier device takes out an optical disk positioned at an end in the thickness direction and whose recording surface faces the inner wall of the magazine, and carries it to the disk drive.

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.

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.
