Claims

[Scope of utility model registration request]

a turntable; a turntable protruding from a disk supporting surface of the turntable and reciprocatingly movable in a direction substantially perpendicular to the disk supporting surface, the turntable being fitted into a center hole of the information recording disk; a centering member for aligning the centering member; a bias force applying means for applying a bias force to the centering member in the protruding direction; a support member that is provided movably in a plane substantially perpendicular to the disk supporting surface and supports the press member rotatably and movably within a predetermined range in the direction of the rotation center axis; , an information recording disk playing device including a magnet for applying a disk pressing force to the pressing member, and a driving means for moving the supporting member, wherein the driving means moves the supporting member as far away from the disk supporting surface as possible. After moving from the first position to the second position closest to the disk holding surface to the first position or any third position between the first and second positions, the disc is once returned to the second position. An information recording disk performance device characterized in that the information recording disk performance device is moved to the third position again, and when the supporting member is in the second position, the supporting member presses the downwardly curved portion against the disk supporting surface.
