Abstract
This letter presents the idea of using the distances along the time-optimal state trajectory for the feedback parameters in the computer disk file servo. The method allows smooth switching between saturated control efforts and can eliminate the common overshoot problem. Due to the nature of the feedback information, the method achieves both track accessing and track following with a single stage of control
