Method and apparatus for disk drive seek control

摘要

A disk drive seek control system device to reduce track pitch. When data is recorded, an offset value is added to the position of a read head element along the width of a track corresponding to an offset DELTAw between the read head element and a write head element. The value of the offset depends on the yaw angle theta of the head. When data is read, the position of the read head element is chosen to be either the position of the write head element during write operations, or the midpoint between the position of the write head element and the read head element during write operations, or the center of a track.
