ABSTRACT:
A magnetic recording disk contains a sector servo pattern for use in a disk file with a multiple element head. The pattern of servo signals is a plurality of segments spaced along radially extending sectors, the sectors being equally angularly spaced around the disk surface. For data track following by the head as the disk rotates, elements of the multiple element head are alternately switched into the servo system so that each element reads the servo signal in the data track in which it is aligned.
