ABSTRACT:
A disk for use in a dedicated surface track following servo system has a plurality of radially spaced circumferential tracks on which synchronizing, position, and track region identifying transition pairs are recorded together with guard transition pairs between the synchronizing and position transitions pairs and between the position and track region identifying transition pairs. The guard and position transition pairs each bridge two adjacent tracks and are separated radially and circumferentially from track to track in repetitive staircase fashion.
