摘要: A silent seek servo controller is used in a low profile miniature disk drive to minimize acoustic noise and the problems associated therewith. The of this invention reduces generation at expense performance. Since minimizes noise, helps eliminate vibrations within computer. one mode continuous position that accelerates decelerates actuator using smooth, completely symmetric acceleration trajectory. Specifically, for time t, accelerated one-half time, i.e, t/2, decelerated other half t. peak occurs t/4 deceleration 3t/4. symmetry each phase assures any generated by uneven eliminated.
