A rotor magnet is attached to the inner peripheral portion of a hub to attach a magnetic disk or the like and a stator is provided in the outer peripheral portion of a bearing housing so as to face the rotor magnet, thereby forming a rotating mechanism. A magnetic pre-load mechanism is provided and a spindle is pressed to one side of a radial bearing, thereby stabilizing the rotation.
