Abstract

Track seeking is the process of moving a recording head over several tracks on magnetic disk to the desired track. Current seek methods move the head either open loop or with velocity feedback to the desired track, then switch to position feedback to hold the head on track. The timing of that switch in feedback modes is critical and position error transients often occur during the transition time.
