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 contacts a top surface of the hub. The clamp includes first and second pluralities of openings therethrough. The clamp is attached to the hub by a plurality of fasteners, each of the plurality of fasteners passing through one of the first plurality of openings. Each of the second plurality of openings has a closed outer periphery within the clamp. Each of the first plurality of openings is disposed directly between the spindle rotation axis and a corresponding one of the second plurality of openings.
