<p>The present invention relates to a disk drive seek control system which is capable of rapidly moving a transducer (18) from an initial position to a target position above a data storage medium (12). The system applies control to an actuator motor means (20) based on projected transducer velocity at a future servo sample time. This allows the system to significantly reduce transducer velocity profile. In addition, the system utilizes dynamically adapted feed forward deceleration current during a deceleration portion of the seek cycle to further reduce velocity errors during the seek cycle, the system significantly reduces the length of time required for settling the transducer (18) on the track (14) of the disk (12) after the seek cycle has ended.</p> |
