ABSTRACT:
A disc cartridge can prevent a disc from being damaged, and smoothly enable a disc rotation, by forming a protruding supporting member to have a predetermined height from an inner surface of a casing receiving the disc, and by preventing the disc from interfering with an outer surface of the casing or other components. The structure of the disc cartridge includes the casing receiving the disc, and a disc holder disposed separably at the casing, having tension arms elastically holding the disc, and guiding the disc into or out of the casing, the protruding supporting member having a predetermined height from the inner surface of the casing and being contacted with a non-recording region of the disc, which height is equal to or greater than a sum of a vertical deflection of the disc due to gravity, a vertical deflection of the tension arms, and an air gap which must be maintained between surfaces of the disc and flanges of the tension arms.
