Abstract
A disc head slider supports a transducer relative to a data storage disc. The slider includes a slider body having a disc-facing surface with a leading slider edge, a trailing slider edge, and first and second slider corners at opposing ends of the trailing slider edge. First and second rails are disposed on the disc facing surface about a central recess and form first and second bearing surfaces, respectively. The central recess has a depth measured from the first and second bearing surfaces. First and second recessed surfaces are positioned between a trailing edge of the first and second rails and the first and second slider corners, respectively, and are generally coplanar with the central recess. Third and fourth recessed corner surfaces are positioned at the first and second slider corners, respectively, and are recessed from the first and second recessed surfaces.
