ジ。 In an optical disk cartridge comprising a main body having a disk storage hole for storing an optical disk medium and a hub for holding the optical disk medium, the hub is slightly larger than the optical disk medium. The main body has a large diameter and includes a magnetic material on at least a part of its outer periphery, and the main body has a first receiving part and a second receiving part formed on the inner wall of the storage hole so as to have a substantially stepped cross section; The first receiving part supports the outer peripheral part of the optical disk medium, and the second receiving part is provided with a magnetic material, and the hub is supported by magnetic action with the magnetic material provided on the hub. An optical disk cartridge characterized in that the optical disk medium is held between a hub and a main body by adsorption.
