ABSTRACT:
A system includes a control module and an estimating module. The control module controls a speed of an actuator arm when the actuator arm moves from a parked position to an edge of a rotating storage medium and generates an arm control signal. The estimating module estimates a force to move the actuator arm based on the arm control signal and the speed, and generates an estimated force signal that adjusts the arm control signal.
