Abstract
An optical disk apparatus is provided, in which the optical disk tray can slide smoothly in and out, and the insertion and removal of an optical disk is facilitated, and wherein inadvertent scratches are not produced on the optical disk surface, and flying pieces of optical disk damaged during rotation are completely prevented from exiting the apparatus. By dividing a protrusion for preventing a damaged optical disk from flying out of the apparatus into a first protrusion and a second protrusion, with one protrusion provided on an optical disk tray and the other on a support member, any possibility of the optical disk flying out of the apparatus can be completely prevented, even if the height of each of the first and second protrusions is lowered. Because the second protrusion is lowered, the protrusion will not catch on the optical disk tray or the optical disk, and so a smooth sliding operation of the optical disk tray can be ensured.
