1. A spindle motor comprising:
a base; a bearing housing supported on the base; a bearing provided within the bearing housing; a rotating shaft rotatably supported by the bearing; a stator fixed to the bearing housing and wound by at least one coil; a rotor including a rotor yoke fixed to the rotating shaft, and a magnet installed on the rotor yoke facing the stator; a turntable positioned on the rotor yoke, rotating together with the rotating shaft, and mounting a disk on an upper surface thereof; a center guide member formed of a plastic material, into which the rotating shaft is inserted at an upper side of the turntable to be capable of rising and descending thereon, the center guide member for supporting the disk; an elastic member for elastically supporting the center guide member; and a back yoke fixed on the rotating shaft at an upper side of the center guide member, for preventing a disengaging of the center guide member from the rotating shaft. |
