摘要：
A compact disk player has a polycarbonate turntable, and a clamper (201) for clamping a compact disk on the turn table. The turn table is made of the same material (polycarbonate) as the compact disk and includes a disk body, a central hub projected from the disk body to receive a center hole of a compact disk and a peripheral annular portion formed integrally with the disk body.
