ABSTRACT:
An alternating "A/B" servo burst pattern for measuring and compensating for offset of the track centerline due to differential magnetic influence to the servo pattern, and a switching network to alternate the output of the servo system demodulators between the inverting and non-inverting terminals of a differential amplifier so that electrical distortion is minimized.
