Abstract:
1. A method for positioning a read/write head in a hard disk drive, comprising: a) providing a disk having at least one side with a plurality of tracks, each of said tracks having a servo field, said servo field having servo bits; b) reading said servo bits to provide a position signal for positioning a read/write head; c) determining a magnitude of a difference in position between an initial and a subsequent position of the read/write head on a track, said subsequent location to occur after said read/write head has moved one revolution from said initial position on said track, said initial and subsequent position being offset laterally; and d) generating a compensation signal based on said initial position, said subsequent position and said difference; e) combining said position signal and said compensation signal to provide acompensated position signal for positioning said read/write head.
