Abstract
Positioning a transducer over a magnetic recording medium for sequential track seeking operations includes performing a data transfer operation on a current track. During the data transfer operation, a next track is identified for the transducer to be moved in a sequential access pattern and movement of the transducer is initiated toward the next track before completion of the data transfer operation on the current track. A feed-forward control signal is determined based on a feed-forward profile including an acceleration table, which is applied to a microactuator configured to move the transducer by applying a voltage to move the transducer in anticipation of the next track position based on a predefined seek profile, and completing the data transfer operation on the current track during a period of latency in the movement toward the next track, such that a portion of the data transfer and the seek operation overlap in time.
