1. A magnetic disk drive device for rotary driving a magnetic disk, the magnetic disk drive device comprising:
a drive motor for rotary driving the magnetic disk, the drive motor comprising a motor hub which has motor hub support portion with a screw-type motor hub engaging portion and with a motor hub support surface for supporting the magnetic disk at a first magnetic disk surface; a clamp disk comprising a clamp disk support portion with a screw-type clamp disk engaging portion complementary to the motor hub engaging portion so that the clamp disk and the motor hub are connectable to each other via a screw engagement between the motor hub engaging portion and the clamp disk engaging portion, and with a clamp disk support surface for supporting the magnetic disk at a second magnetic disk surface opposite the first magnetic disk surface, the clamp disk support surface facing the motor hub support surface when the clamp disk and the motor hub are in screw engagement, thereby allowing the magnetic disk to be supported between the motor hub and the clamping disk in a clamping manner by being clamped in between the motor hub support surface and the clamp disk support surface.
