ABSTRACT:
An air bearing slider for supporting a magnetic transducer comprising a pair of coplanar side rails on the sides of an air bearing surface of the slider and a center rail along the central region of the air bearing surface to form recessed areas between the rails which extend from the leading to the trailing end of the slider. All the rails have a tapered section at their leading ends. The side rails have a width that does not exceed the width of the side rails at the leading end, and the side rails extend only part way to the trailing end of the slider. The width of the center rail is small at the leading end and greatest at the trailing end of the slider, where the transducer is supported.
