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 raised side rails are positioned along the first and second side edges, respectively. The side rails each form an air bearing surface with an inside and an outside edge extending between the leading edge and the trailing edge. A raised cross rail is positioned near the leading edge and extends between the side rails. A negative pressure cavity is positioned between the side rails, trailing the cross rail. A first isolation channel is disposed between the first side rail and the negative pressure cavity. A second isolation channel is disposed between the second side rail and the negative pressure cavity. Intermediate surfaces extend along only a portion of the inside edges of the airbearing surfaces formed by the first and second side rails. The intermediate surfaces are recessed from the air bearing surfaces and are raised from the isolation channels.
