ABSTRACT:
A method and apparatus for increasing recording density in zone bit recording on a magnetic recording disk without increasing track density by maximizing the data density the at disk's outer track. A magnetic recording head is attached to a parallelogram shaped slider such that the head's gap-to-radius skew and the slider rail skew changes continuously as the slider moves in an arcuate path from the disk's inner track to the disk's outer track. The parallelogram slider is designed to reduce the loss of data density at the outer track by minimizing the head's gap-to-radius skew while maximizing the rail skew angle at the outer track to maintain an essentially constant low fly height across the disk.
