ABSTRACT:
A disc cartridge includes a cartridge main body composed of a lower shell, in which a first opening that enables disc access for a disc-like recording medium in a housed state is formed, and an upper shell, a disc tray that is rotatably provided inside the cartridge main body and formed so that the recording medium can be mounted thereon, and a single shutter member disposed between the lower shell and the disc tray. A second opening, which enables disc access for the recording medium when the second opening overlaps the first opening in a thickness direction of the disc cartridge, is formed in the disc tray. The disc tray closes part of the first opening in a restricted state where the disc access is restricted, and is capable of opening the part of the first opening in a disc access state by being rotated inside the cartridge main body and causing the shutter member to slide. The shutter member closes another part of the first opening in the restricted state so as to close the first opening in concert with the disc tray, and in the disc access state the shutter member is caused to slide by the disc tray so as to be capable of opening the other part of the first opening.
