Abstract
A self-loading air bearing disc head slider supports a transducer proximate a rotating disc. The slider includes a slider body having 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 first and second side rails each form an air bearing surface. A cross rail is positioned at the leading edge and extends between the first and second side rails. The cross rail includes a relief or 'notch' which is recessed from the air bearing surfaces. The relief minimizes debris collection at the leading edge and reduces pitch angle. The leading edge can include a leading edge taper with a relief which communicates with the relief in the cross rail.
