ABSTRACT:
An air bearing slider is provided for supporting a magnetic transducer and the slider comprises a pair of coplanar side rails disposed on the sides of an air bearing surface of the slider to form a recessed section between the side rails which is open at both the leading and trailing ends of the slider. The side rails have a tapered height section at the leading end and a width that decreases to a break point located between the ends. The air bearing structure produces a combined pressure profile which causes the slider to fly with the leading end at a desired pitch angle relative to a moving magnetic medium, with the minimum spacing between the slider and the magnetic medium at the trailing end, where the magnetic transducer is mounted.
