置。 A disk drive device that rotatably drives an information recording/reproducing disk supported by a turntable and a clamp member, wherein the clamp member is provided with a magnet, and the turntable is made of a non-magnetic material that is lighter than a magnetic material. It is made of a magnetic material, and has a built-in disc-shaped magnetic plate in its center that cooperates with the magnet of the clamp member to generate a magnetic attraction force to support the disc, and is located opposite to the clamp member of the turntable. A disk drive device characterized in that a magnet is disposed on the side of the turntable in cooperation with the disk-shaped magnetic plate to apply a magnetic attraction force to the turntable in the direction of the rotational axis and in the radial direction.
