ABSTRACT:
Improved configurations of Negative Pressure Air Bearing Flyers ("NPAB") for use with the rotary actuator of a "Winchester" disk drive lessen slider roll, provide for constant, low slider flying height and a short take-off regardless of skew. One set of configurations uses two isolation channels cut into the NPAB to isolate the side rails from the central negative pressure cavity. Another set of configurations divides the negative pressure cavity into two cavities and provides openings in the leading crossbar to decrease the pressure in the cavity near the upstream rail while increasing it at the downstream rail. Another configuration provides an increased leading taper for fast take-off in combiantion with a pressure relief channel anterior the negative pressure cross rail to maintain negative pressure in the cavity.
