PURPOSE: A disk cartridge and its fabricating method are provided to control a disk to an appropriate height within a case by raising an inner rib supporting the disk and to prevent a mutual interference between the disk and a disk holder by controlling the height of the disk. CONSTITUTION: A case(21) is provided with an inner rib(21a) to maintain the height of a disk(10) at the combining position between the disk(10) and a tension arm(2). The tension arm(2) holds the disk(10) through a receiving opening formed at the case(21) and guides the disk to the inside of the case(21).
