Abstract
An air bearing slider for supporting an electrical magnetic transducer over a rotating magnetic disk has a slider body and first and second side rails. The slider body has 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 have a convex crown ranging between about 0.50 micro inches and about 3.0 micro inches. An interface surface of the slider facing the surface of the magnetic disk has a three-dimensional roughness average ranging between about 0.20 micro inches and about 0.60 micro inches. The three-dimensional roughness average is an average of depth variations across the surface of the slider and is dependent upon crown, camber, twist, flatness, cylindrical sag, profile variations and edge blend of the air bearing slider.
