Abstract

PURPOSE:To simultaneously realize the thinning and large capacity of a device by providing a magnet facing the ferromagnetic body provided on the edge surface of a turn table rotary shaft at a holder to pressure a disk on a turn table. CONSTITUTION:To the edge part of a rotary shaft 13 to fix a table 14 to turn a turn table 14 where a disk 12 is mounted, a ferromagnetic body screw 17 is screwed. With a holder 19 equipped with a magnet 18 facing the screw 17, the disk 12 is directly pressured to the table 14. Consequently, the thickness between the magnet 18 and the screw 17 at the time of clamping a disk 14 can be set small regardless of the thickness, etc., of the disk, the disk is directly pressed without being influenced with dust, etc., and a clamping device can be thinned. Simultaneously, the turn table and holder diameter can be made into the necessary small diameter in order to convert magnet absorption force to the rotational direction friction torque of the disk and the large capacity of the disk can be realized.
