Abstract
A slider comprises an air bearing surface having a leading edge at a first end of the air bearing surface; a trailing edge at a second end of the air bearing surface, wherein the first end is opposite to the second end; a first region adjacent to the trailing edge, wherein the first region comprises one or more transducer elements; and a second region adjacent to the first region and the leading edge. The air bearing surface has a protective overcoat layer as an outermost layer, wherein the protective overcoat layer extends across the entire air bearing surface. The air bearing surface comprises a lapped surface and a plurality of milled surfaces, wherein a surface potential difference between the lapped surface and a milled surface is 0+/−50 milliVolts or less as measured according to Kelvin Probe Force Microscopy (KPFM).
