ABSTRACT:
The air bearing surface of an air bearing slider is configured with a taper formed at the slider leading end and a rail that is formed with a base and two legs. One leg extends from the base partially toward the trailing end. The other leg extends from the base to the trailing end and is integrally formed of a rectangularly shaped section and one or more polygon-shaped sections. Inner and outer recesses are defined and separated by the rail, such that the slider is effectively insensitive to changes in ambient pressure, particularly from variations in altitude, so that a substantially constant flying height can be maintained.
