ABSTRACT:
A disk drive that has a plurality of heads coupled to one or more disks. The heads have air bearing surfaces that compensate for a radial crown and a radial camber of an adjacent disk to maintain a flying height at a relatively constant level across the disk surface. By way of example, the air bearing surfaces may have crown and camber sensitivities that are opposite in sign from the crown and camber sensitivities created by the disk. The opposite sensitivities offset the sensitivities of the disk to maintain an essentially constant flying height as the head moves across the surface of a disk.
