ABSTRACT:
A disc cartridge capable of preventing a recording surface section of a disc from being contacted with an inner surface of a casing so that the disc may be free from any damage. The disc cartridge includes steps or sheet-like members provided on the inner surface of the casing in a manner to be inwardly projected from the inner surface. The steps or sheet-like members are positioned so as to be engaged with a non-recording surface section of the disc to support the disc thereon, so that a clearance may be defined between the recording surface section of the disc and the inner surface of the casing.
