A spindle motor assembly includes a spindle motor, a disk for storing data, the disk being installed on the spindle motor, and a disk clamp for fixing the disk to the spindle motor. The disk clamp includes a hollow formed in a central portion thereof, a coupling portion formed around an external circumference of the hollow and including a plurality of screw insertion holes into which clamp fastening screws to be coupled to the spindle motor are inserted, and a pressing portion formed around an external circumference of the coupling portion to press the disk. The coupling portion includes a first region and a second region that are asymmetrical with respect to each other, the plurality of screw insertion holes are formed in the first region only, and a thickness extension portion or a through hole is formed in at least a portion of the second region.
