Abstract

A read/write apparatus which enables setting and removal of a read/write compact disk within a limited space of the apparatus includes a turntable 83 having a cap portion 123 that permits a center hole h of a read/write compact disk to be fitted therearound. Clips 124 are capable of advancing and retreating from a rim of cap portion 123 of turntable 83. A setting/removing lever 136 is provided in such a manner that setting/removing lever 136 is capable of rotating by a specified angle with respect to turntable 83. A head 85 which is capable of moving parallel to the radius of the read/write compact disk to perform reading or writing of the read/write compact disk is provided. Head 85 has a stopper 145 which catches a catching portion 139 of setting/removing lever 136 at a position head 85 approaches closest to turntable 83. Cap portion 123 is provided with a setting/removing device 125. During forward rotation of turntable 83, setting/removing device 125 catches stopper 145, thereby causing clips 124 to advance. During reverse rotation of turn table 83, setting/removing device 125 catches stopper 145 and which enables clips 124 to retreat.
