A spindle motor assembly usable with a hard disk drive includes at least one data storage disk, a spindle motor to drive the disk, the spindle motor having a hub on which the data storage disk is fixed, and a clamp member to fix the data storage disk to the hub by pressing the data storage disk axially toward the hub. When the clamp member presses a first location of the data storage disk and the hub has a supporting center corresponding to a second location of the data storage disk, the first location is closer to a center of the data storage than the second location.
