ABSTRACT:
A multi-disk player according to the invention has a disk table which comprises (1) a large size disk mounting section on which a large size disk is mounted, (2) a turn table rotatable about an axis which is a predetermined eccentric distance away from the axis of the large size disk mounting section. The turn table includes thereon a plurality of small size disk mounting sections on each of which a small size disk is placed. The eccentric distance is determined such that the axis of each small size disk mounting section is made to coincide with the axis of the large size disk mounting section by rotating the turn table.
The player having such an arrangement has a disk driving device whose circuit structure is simplified, and solely plays a plurality of types of disks having different diameters such as CDs and LDs.
Further the player plays a disk arbitrarily selected from a plurality of small size disks and successively plays a plurality of small size disks.
