A method for preparing the air bearing surface of a slider for etch patterning including the steps of applying a first thin film to a carrier, applying a second thin film to the carrier, the first thin film and the second thin film separated by a recess, each of the first and second thin films having respective first and second air bearing surfaces, applying an adhesive film over the first and second thin films, depositing a fluid in the recess, the fluid held in the recess by the adhesive film, curing the fluid, and removing the adhesive film. The method of the invention may also include coating the first and second air bearing surfaces with an etch mask, developing the etch mask, and patterning the first and second air bearing surfaces.

The present invention discloses a slider having an alumina overcoat layer that is etched so as to be tapered, sloped, inclined, recessed, or faceted with respect to the air-bearing surfaces of the slider. The present invention also relates to a method for eliminating overcoat protrusions by etching away portions of the alumina overcoat layer at row level. Preferably, photolithographic techniques are used at row level to both etch the air-bearing surfaces of the slider and to etch away potential protrusion regions of the alumina overcoat.
