PURPOSE:To miniaturize a whole disk player by providing concentrically two kinds of turntables, and sharing a disk clamp mechanism for both turntables. CONSTITUTION:With respect to a shared rotation driving source containing a spindle 11h, the first and the second two kinds of turntables 12, 14 are provided concentrically, and also, so that the second turntable 14 of the outside is always separated from the moving path of a pickup, and provided with a first pressing member 63 by which a disk clamp mechanism presses the disk against the first turntable 12, and a second pressing member 64 for supporting this first pressing member 63 so as to be freely rotatable, and also, freely movable in the rotary axis direction of the spindle 11h, and pressing the disk against the second turntable 14. Since both turntables are provided concentrically, the player can be miniaturized easily, and also, its cost can be reduced.
