Abstract
A turn table in an optical disk apparatus in accordance with the present invention is provided with a mount section for use in a mini disk (MD) at the top portion thereof and another mount section for use in a compact disk (CD) at the base portion thereof. This arrangement makes it possible to drive optical disks of different types by the use of the same turn table. Below the turn table, are installed an optical pickup and a base plate that is provided with switches for discriminating whether the MD in question is dedicated solely to reproduction use or is used for both recording and reproduction, and positioning pins for the MD. The optical pickup is also allowed to move in the radial direction of the disk by support members. The optical pickup, the support members and the base plate are integrally moved up and down between a station close to the MD and a station close to the CD. This arrangement eliminates the necessity of an adapter that enables optical disks of different types to be appropriately placed on the turn table, and makes the optical disk apparatus compact by integrating various mechanisms.
