Abstract:
A disk drive includes a spindle motor attached to a disk drive base. The spindle motor includes a hub that rotates about a spindle rotation axis. An annular disk is mounted on the hub. A clamp is attached to the hub. The clamp has a body portion that is stamped from a metal sheet. The clamp also includes an annular rib that protrudes from the stamped sheet metal body portion towards the annular disk. The annular rib includes an annular contact surface that may be lapped to enhance flatness and that contacts the annular disk. The annular rib also includes inner and outer side walls that are each normal to the annular contact surface.
