ABSTRACT:
A control system and method for a disk drive comprising first and second actuator arms. The control system comprises first and second stages and a reset system. The first stage displaces the first arm. The second stage displaces the second arm relative to the first arm. The second stage defines a displacement offset when the disk drive begins a seek operation. The reset system discharges at least a portion of the displacement offset over time.
