Abstract
Servo control apparatus including a recording head to read first and second servo data bytes stored across a track on opposite sides of a track centerline, a servo demodulator to count the first and second bytes and produce a resultant count representing any offset of the head relative to the centerline, a head positioner to move the head, and a microcomputer which controls the head positioner to position the head in response to the resultant count. The invention is implemented digitally, is simple and inherently compensates for expansion or contraction of the track to accurately center the head.
