Abstract
An optical disk polishing device which includes: a disk holder for rotatably holding an optical disk, the disk holder installed in a lower fixed portion; a cylindrical buff disposed in parallel with the surface of the optical disk and perpendicular to a rotary shaft of the disk holder in an offset manner; a drive motor to rotate the buff; and an upper opening-and-closing portion normally urged to an open state to the lower fixed portion by a spring or other member. The device makes it possible to clean a readout surface of the optical disk in a short period of time, and to be offered at a low price owing to the simple and small-sized structure thereof.
