Abstract
A disk spacer interposed between a plurality of disks that are rotatably installed on a spindle motor and has a ring shape to maintain an interval between the disks. The center of an inner circle defined by an inner circumferential surface of the disk spacer is not congruous with the center of an outer circle defined by an outer circumferential surface thereof to produce mass eccentricity.
