ABSTRACT:
A flexible disk drive in which the head moves in an arc, as the head is selectively moved to access the data at the various concentric data tracks of a disk. Concomitant with this approximate arcuate movement, the head is azimuth-rotated, such that its gap has a predefined, optimum azimuth orientation to each of the individual disk tracks, for example, the head's gap is normal to the track's center line at each head position.
