ABSTRACT:
A servo control method of a disk recording system for detecting position of a head using a digital servo control method in which a disk contains an embedded burst recording region comprising four servo bursts. The servo control method contemplates on reading track identification information and servo burst information on the disk recording medium, determining whether a track on which the head is positioned is one of an odd and even track from the track identification information and the servo burst information, and generating an odd/even information bit and first and second position error signals in accordance with the determination; generating seek information from addition/subtraction to and from the odd/even information bit and the first and second position error signals; and correcting the track identification information in correspondence with the seek information and outputting a current position error signal.
