Embodiments for passive retraction of a hub clamp in an optical disc drive. The optical disc drive may comprise a spindle hub coupled to an optical assembly. The optical disc drive may further include a disc clamp assembly configured to hold an optical disc on the spindle hub, the disc clamp assembly including a hub clamp partially comprised within a clamp carriage. The hub clamp of the optical disc drive may be biasedly drawn toward the spindle hub when in a first position and biasedly drawn toward the clamp carriage when in a second position. The bias may be generated by at least one ferromagnetic material integrated into the hub clamp and at least one ferromagnetic material integrated into the spindle hub.

A system includes a library compartment, a player and a gas generator. The library compartment houses a plurality of data storage disks. The player is external to the library compartment and comprises a head that is configured to interact with at least one of the plurality of data storage disks. The gas generator is fluidly connected to the player. An embodiment includes a partition between the library compartment and player, the partition including a selectively openable interlock. In an embodiment, the player has a negative fluid pressure relative to the library compartment. A method of controlling an environment in a disk player is also described. The method includes detecting a composition of a fluid environment in the disk player and detecting a pressure of the fluid environment in the disk player.

A mover replacement system for removing a media mover, movable between an operating position and a removable position, from within a media library includes a module housing and a service tray. The module housing forms at least a part of a library housing. The service tray is removably positionable within the module housing. The service tray is configured to releasably retain the media mover when the media mover is in the removable position so that the service tray and the media mover are movable as an integral unit out of and into the module housing. The service tray includes a tray body and at least one locking mechanism that is movable relative to the tray body between a retracted position when the at least one locking mechanism is positioned not to engage the media mover, and a fully extended position when the at least one locking mechanism is positioned to retain the media mover relative to the tray body.

An apparatus with a housing which stores a plurality of data storage magazines, where each data storage magazine includes a plurality of data storage devices. The housing includes a movable carriage, the movable carriage configured to selectively couple a set of data storage devices held by a particular data storage magazine to a host device. The housing also includes a motor configured to move the movable carriage within the housing to enable the movable carriage to communicatively couple the set of data storage devices held by the particular data storage magazine to the host device

The disc device comprises disc selector spindle that hold discs in a stacked state, separate lowermost disc from other discs, and supply separated lowermost disc to drive unit. The disc selector spindle includes first, second, and third support claws that move to storage position at which each support claw is stored inside center hole of disc and protrusion position at which each support claw protrudes in a region located in the vicinity of inner diameter of disc in plan view. First support claw moves to storage position and protrusion position independently of the movements of second support claw and third support claw. Second support claw is disposed so as to be shifted from third support claw in a stacking direction of disc by a thickness of one disc, and to move from storage position to protrusion position at a timing different from a timing of third support claw.

A disc storage device rack includes: an accommodation space surrounded by left and right side plates and upper and lower partition plates and configured to accommodate a disc storage device; a guide portion provided on the side plates and configured to fit to a guided unit provided in the disc storage device to guide a sliding operation of the disc storage device; and a shutter provided on each end surface of the side plates so as to be slidable in an up-and-down direction and configured to open an opening of the guide portion when the disc storage device is pulled out from the accommodation space or when the disc storage device is pushed into the accommodation space.
