Abstract

A disc cartridge for receiving a disc includes a case which accommodates the disc and at least one centering spring which prevents deviation of the disc in the case. Thus, a gap in which the disc moves in the disc cartridge is restricted so as to reduce a length in which a disc clamp of the disc contacts a disc clamp guide inside a disc drive system. Accordingly, the height of the disc clamp is reduced so as to reduce the thickness of the disc cartridge and miniaturize the disc cartridge.
