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.

A disc cassette includes a curved portion. The curved portion includes multiple ribs that define multiple disc slots. The disc slots are configured to hold multiple discs that are spaced apart by the ribs. The disc cassette further includes multiple index features positioned on an inside edge of the curved portion. The index features are configured to allow alignment of a kicker device of a disc retrieval unit (DRU) to a disc of the disc cassette to lift the disc into a disc gripper device without disturbing one or more other discs of the disc cassette that are adjacent to the disc.

Provided is a disc storage device including: a casing capable of storing a stacked body including one or a plurality of disc-like recording media and a spacer interposed between the disc-like recording media and an inner surface of a bottom plate; a position regulating unit that regulates a storage position of the stacked body inside the casing; and a plurality of through holes formed in an area of the bottom plate of the casing where the spacer is provided, in which the spacer is adsorbed to tips of pins to be inserted through the through holes.

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.

Apparatus for data storage in a cartridge library archival system. In some embodiments, a plurality of portable data storage cartridges are provided. Each cartridge has a sealed housing which encloses at least one head-disc interface (HDI) with a magnetic data transducer adjacent a rotatable data recording medium. An access station has control electronics configured to transfer data signals between a memory and the transducer of a selected cartridge loaded to the access station. The access station further has an external voice coil motor (VCM) configured to engage and advance the transducer of the selected cartridge across a recording surface of the medium. A transport mechanism can be used to automatically load the cartridges to the access station. Multiple cartridges can be loaded sequentially or concurrently to support various data transfer operations.

A disc cassette includes a curved portion configured to hold multiple discs. The disc cassette further includes a bottom side including track connectors configured to position the disc cassette relative to one or more track portions that hold the disc cassette in place. The disc cassette is slideable along the one or more track portions.

A disc storage apparatus includes: a case including an opening on an upper surface of the case and capable of storing N rows of stacked M disc-shaped recording media (N and M each indicate a positive integer of two or greater); a tray cover configured to slide from a rear end of the case and cover the opening; and a locking mechanism configured to lock a state of the opening being covered.

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 conveyance robot apparatus includes modules positioned in a row; a robot for conveying each of the modules and loading and unloading a magazine tray from one of the modules; a pinion mounted on the robot; racks that are slidably supported on the modules and can mesh with the pinion; and a rack connecting mechanism for connecting adjacent racks to each other.

Provided is a disc archive apparatus, including: a tray conveying robot that selects a specified disc tray and conveys the specified disc tray; a rotatable turn table, the disc tray conveyed by the tray conveying robot being placed on the rotatable turn table; a disc conveying picker for placing the discs from the disc tray placed on the turn table into the plurality of drives of the disc drive; and a controller that controls an operation, in which the controller performs a control operation including performing processing including recording or reproduction on/from the disc taken out from a disc tray currently placed on a first area of the turn table, rotating the turn table thereafter, and performing processing including recording or reproduction on/from a next disc tray placed on a second area of the turn table.
