ABSTRACT:
A movable head support arm establishes a curved path and orientation for the head along a memory disc such that the head gap is maintained tangential to the path. A variable delay of the track reference, established as a function of track position, is developed to insure coherence of stored information from track to track in the direction of the head path.
