摘要：
A disk cartridge is provided which includes an optical disk (2), a cartridge body (5) having formed therein a head opening (13) through which a part of the optical disk (2) is exposed to outside in a range between the inner and outer radii thereof, a shutter member (15) supported movably on the cartridge body (5) to uncover and cover the head opening (13), and a two-way forcing mechanism (38) to force the shutter member (15) toward any selected one of positions to cover and uncover the head opening (13). The two-way forcing mechanism (38) forces the shutter member (15) toward any selected one of the positions to cover and uncover the head opening (13) correspondingly to a position of the shutter member (15) relative to the head opening (13).
