Abstract
A head disk assembly for a hard disk drive employs a rotary actuator apparatus including a pivot shaft that defines an actuator axis of rotation. A pivot bearing assembly including a pivot bushing having a plurality of fingers supports rotation of the actuator about the pivot shaft. Each of a plurality of fingers has a bearing end that is in sliding contact with the pivot shaft. The fingers are formed from a material in a shape that provides the stiffness and low coefficient of friction necessary for the desired pivot bearing performance.
