徴とするデイスク駆動装置。 It has a chuck magnet on its mounting surface, a turntable with a spindle shaft and a drive pin protruding from the mounting surface, and a motor for rotationally driving the turntable, and a tracking hole and a positioning hole are drilled therein. In a disk drive device that records or reproduces information by loading an information recording disk having a metal hub onto the mounting surface of the turntable, the drive pin is rotated so that the metal hub of the information recording disk rides on the tip of the drive pin. When a part of the metal hub is regulated by the turntable, the other part is formed at a height regulated by the inner surface of the information recording disk storage case facing the turntable, and is fixed to the turntable. A disk drive device characterized by:
