ABSTRACT:
A cartridge body has a disc storing portion for rotatably storing an optical disc, and a disc inlet/outlet port. A lid member for opening/closing the port is mounted on the cartridge body. The port includes a mid portion through which a center portion of the disc passes and a pair of end portions positioned on both sides of the mid portion through which peripheral portions of the disc pass. The width of the port gradually decreases from the mid portion to both end portions. The disc storing portion includes a center region facing the center portion of the disc, a first region extending from the center region to the port, and a second region extending from the center region in a direction opposite to the port. The first region has a cross-sectional shape equal to that of the port, and the second region is formed such that its width decreases in the radial direction from the center portion of the disc toward outer peripheral portions of the disc.
