Abstract
A negative pressure air-bearing slider comprises a slider body having a surface with a leading edge, a trailing edge and first and second side edges. First and second side rails are positioned along the first and second side edges, respectively. The side rails each form an air-bearing surface which develops positive pressure during flight. A raised crossed rail is positioned near the leading edge and extends between the side rails. A negative pressure cavity trails the cross rail and is positioned between the side rails. A first isolation channel and a first isolation separating rail are positioned between the first side rail and the negative pressure cavity. A second isolation channel and a second isolation separating rail are positioned between the second side rail and the negative pressure cavity. The isolation channels and the isolation separating rails terminate prior to the trailing edge of the slider.
