<p>PROBLEM TO BE SOLVED: To provide an optical disk capable of reducing the number of components while preventing deformation of a tray.SOLUTION: The optical disk comprises: a drive unit support member for supporting a rotation drive unit that drives an optical disk to rotate; and a tray for receiving the optical disk in a loading state, the rotation drive unit and the tray being formed with an identical member and separated from each other by a slit excluding a part thereof. A connection part connecting the drive unit support member and the tray is formed at any part of the slit in an extension direction of the slit. The drive unit support member and the tray are handled as one integrated article and thus the number of components can be reduced. By separating the drive unit support member and the tray with the slit, even when disk insertion operation is repeated on the rotation drive unit, the tray is prevented from getting deformed. Thus, the tray does not deform after a long period of use.</p> |
