ABSTRACT:
An air bearing slider design exhibiting reduced altitude sensitivity and requiring only two etch depths for ease of manufacture. The slider includes a support structure having a leading and trailing step surface disposed thereon. The leading step surface has two side rails joined together at the leading edge and extending toward the trailing edge, forming a negative pressure pocket therebetween. A front pad is formed on the leading step surface and a trailing pad is formed on the trailing step surface. The side rails have a length that is selected for creating a predetermined negative pressure. The trailing and leading step surfaces preferably have a height above the support structure of between 0.5 .mu.m and 5 .mu.m. Preferably, the front and rear pads have a height above the leading and trailing step surfaces respectively that is less than the height of the step surface above the support structures. The side rails may extend substantially to trailing edge. The trailing step surface may include trailing step surfaces adjacent the trailing edge designed to vary the effect of the negative pressure pocket.
