[Scope of Claim for Utility Model Registration] Recording is performed by storing a disk, which is a recording medium, in a cartridge made of upper and lower halves molded from synthetic resin, and rotating the disk with the disk suspended approximately midway between the upper and lower halves. In a disk cartridge configured to perform playback, the wall thicknesses of the upper and lower halves of the cartridge are adjusted such that the gap between the upper and lower inner surfaces of the upper and lower halves of the cartridge is large at the outer circumference and gradually becomes smaller toward the center. A disk cartridge characterized by being formed into a shape that gradually becomes thicker from the outer circumferential side to the center side.
