Abstract

With asymmetric read heads such as some magnetoresistive read heads it is difficult to center the head over a track with amplitude or phase sensitive servoing. This problem can be overcome by providing burst detectors to detect signals so that centering tracks can be quickly recognized as the head crosses an edge of a track.
