Abstract

A disc cartridge having a disc for recording information signals and a main cartridge body member for rotatably housing the disc. The disc cartridge is designed to be loaded on a recording and/or reproducing apparatus. The main cartridge body member has, on its one surface, a label area for bonding a display label indicating the recording contents of the information signals, while having, on its other surface, a spindle hole for rotating the disc by the recording and/or reproducing apparatus. The main cartridge body member has a design parameter discriminating hole extending along the back side opposite to the front side in the cartridge inserting direction. The recording capacity or design parameters of the disc housed within the main cartridge body member may be discriminated by detecting the design parameter discriminating hole.
