Abstract
A disk drive pivot assembly has a locally deformable internal sleeve that is equipped with two small deformable zones where the sleeve makes contact with the actuator comb bore. The zones can be in the shape of two rings with a rectangular or circular cross-sectional shape. The material may include zinc, magnesium, copper, or aluminum, or their alloys. These materials are relatively soft and have a relatively low stiffness compared to the comb bore. The thickness of the rings may range from approximately 0.25 to 1.0 mm, and they may be attached via shrink fit or adhesive bonding.
