Abstract:
A disk drive is disclosed comprising a microactuator configured to actuate a head over a disk, and control circuitry comprising a first digital accumulator responsive to a first register. The first digital accumulator generates at least one of a velocity command and a position command for the microactuator, and the control circuitry configures the first register in order to limit at least one of a velocity and an acceleration of the microactuator.
