Abstract
An apparatus includes a slider body having a leading edge and an opposite trailing edge, as well as a top face and a bottom face each extending between the leading edge and the trailing edge. The slider body further includes a plurality of protrusions extending from the bottom face, a first recess defined on one of the protrusions, and a sacrificial layer deposited on the slider body in the recess. A bottom surface of the sacrificial layer extends at least as far from the bottom face as bottom surfaces of the plurality of protrusions. In another aspect, a first blocking feature is located at a first uptrack edge on an air bearing surface of a slider, with the first blocking feature being substantially continuous along the first uptrack edge and protruding outwardly from the air bearing surface to reduce particle interaction with the air bearing surface.
