摘要： 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.

摘要： A clamping plate includes a circular-plate-shaped main plate and a cylindrical outer wall formed by bending an outer edge portion of the main plate. The clamping plate moves due to being pulled by magnetic attraction by a disc rotating mechanism to clamp a disk-shaped recording medium to the disc rotating mechanism. At least one of a convex that protrudes outward in a radial direction of the main plate and a concave that is depressed inward in the radial direction is formed in the outer wall.

摘要： A cartridge accommodates a recording medium etc, and includes an opening and a shutter for opening and closing the opening. The shutter surface is formed with a hole with which an external drive member engages for driving the shutter. An inner side peripheral surface of the hole, upon which at least the drive member impinges when opening and closing the opening, is constructed of a bending portion continuous from the shutter surface. The bending portion can be worked as a continuous surface by punching out a prepared hole so as to leave a portion corresponding to the bending portion and thereafter bending it. A resinous protection layer having a thickness more than 12 &mgr;m is provided on the shutter surface upon which the drive member impinges when engaging with the hole.
