ABSTRACT:
A spindle motor and a mounting device for mounting a disk in a spindle motor are provided. The mounting device allows for a reduced number of parts, a reduction in product cost, a disk to be smoothly slid and securely mounted to a turntable, and prevents deforming of a disk during mounting. A center guide member is formed of a plastic material, into which the rotating shaft is inserted at an upper end of the turntable, so that it is capable of rising and descending thereon. The center guide member supports the disk. A back yoke is fixed at an upper side of the center guide member on the rotating shaft, to prevent disengaging of the center guide member from the rotating shaft. An outer portion of the center guide member gradually widens toward a lower end thereof, so that the disk can be inserted more securely.
