Abstract
Abstract The air bearing surface of a self-loading magnetic head slider (10) has a front section (16), two side rails (12,14) and a recessed section (18) there-between. The air bearing surface has a convex curved shape in longitudinal section to provide very small spacing between the trailing end of the slider, which supports magnetic transducers (24,26), and a moving magnetic medium thereunder.
