<p>A disk cartridge is provided which houses an optical disk (2) rotatably. It includes a cartridge body (5) having formed therein a head opening (13) through which a part of the optical disk (2) is exposed to outside, and a shutter member (15) supported movably on the cartridge body (5) to uncover and cover the head opening (13). A first concavity (37) is formed on a side of the cartridge body (5) over which the shutter member (15) slides and in a region opposite to a region where the shutter member (15) is moved, across the head opening (13), a bent portion (36) is formed along one lateral side of the shutter member (15) to close a gap resulted between the shutter member (15) and first concavity (37) when the shutter member (15) has been moved to a position to cover the head opening (13), and a second concavity (38) deeper than the first concavity (37) is formed at a part of the first concavity (37), adjacent to the head opening (13)</p> |
