An opening and closing device comprises a disc tray, a mounting shaft and a jukebox manipulator. The disc tray is mounted on the mounting shaft. A positioning structure is provided between the disc tray and the mounting shaft. The mounting shaft is mounted on an outer circumference of a jukebox rotating cage. The jukebox manipulator is mounted on a manipulator driving unit. A side of the manipulator driving unit is provided with an optical drive, the jukebox manipulator is provided with a driving plate structure and the disc tray is provided with a driving lever. When the jukebox rotating cage rotates, the disc tray can revolve around the rotating shaft of jukebox rotating cage and can rotate around the mounting shaft. With the assistance of in-place bumping post which is provided by a side of the jukebox rotating cage, the positioning structure can locate the rotation of disc tray at a fixed static angle.

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.

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.

An opening and closing device of rotating cage type jukebox disc tray including a first disc tray carrying discs and an opening and closing mechanism of disc tray including a first linkage mechanism and a first driving device is provided. The first linkage mechanism includes a first linkage bar, a first sliding member and a second linkage bar. The second linkage bar is slidingly disposed on the first sliding member which is slidingly disposed on the first linkage bar. When an end portion of the second linkage bar is connected to a first ear portion on a lateral side of the first disc tray, the first driving device drives the first sliding member to slide on the first linkage bar, leading the second linkage bar to slide on the first sliding member and thereby leading the first disc tray to rotate around a first fixing post.
