装置。 a turntable having a support surface that directly supports a metal hub in the center of an information recording disk; a chuck magnet disposed on a surface of the support surface that faces the metal hub; and a positioning device that protrudes from the turntable and is formed on the metal hub. It is equipped with a drive pin that engages with the hole and a support means that supports the drive pin on the turntable side, and magnetically chucks the metal hub of the information recording disk through the spindle shaft fitted in the center of the turntable. In a disk chucking device for rotationally driving an information recording disk by a rotational driving means, the supporting means is formed of a member made of a spring material whose rigidity in the twisting direction is greater than the rigidity in the bending direction, and one end side of the is fixed to a turntable, and a drive pin is provided upright on the other end.
