The present disclosure includes methods of using a sacrificial, protective head overcoat during the manufacture of sliders. In some embodiments, the final trailing edge topography of the transducer devices is formed before applying the sacrificial, protective head overcoat. In some embodiments, the final trailing edge topography of the transducer devices is formed after removing the sacrificial, protective head overcoat.

Method of forming one or more sliders

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+/&#x2212;50 milliVolts or less as measured according to Kelvin Probe Force Microscopy (KPFM).

One or more sliders that include a protective overcoat that extends across the entire air bearing surface

The present disclosure relates to kiss lapping sliders after patterning an air bearing surface pattern, followed by applying a protective overcoat to the air bearing surface. The present disclosure also involves related sliders.
