Claim:
A disk clamping apparatus for securing a data storage disk to a spindle motor of a hard disk drive, comprising: A hub body including a flange along an outer periphery of the hub of the spindle motor; and a clamp, having a hollow portion in a center of the clamp, to engage an upper end portion of the hub, and including a hook for snapping onto the flange along an inner periphery of the flange and a pressing portion, along an outer periphery of the clamp, to contact with an upper surface of the disk for pressing the disk in a vertical direction, wherein when the clamp is coupled to the hub a deformation of the clamp snaps the hook onto the flange and the pressing portion presses the disk in the vertical direction using a resilient force generated from the deformation of the clamp, wherein the clamp further comprises a cap formed around the hook and covering a top of the hub.
