1. A method of forming one or more sliders, wherein the method comprises:
a) providing a substrate comprising one or more slider intermediates, wherein each slider intermediate has an air bearing surface and comprises a transducer region, wherein the transducer region comprises one or more transducer devices;
b) forming a final trailing edge topography in the transducer region;
c) after the forming, applying a sacrificial protective head overcoat to cover the air bearing surface, wherein the sacrificial protective head overcoat comprises at least one sacrificial protective head overcoat layer;
d) after applying the sacrificial protective head overcoat, patterning the air bearing surface of each slider intermediate to form an air bearing pattern;
e) after the patterning, removing the sacrificial protective head overcoat to expose the final trailing edge topography; and
f) after removing the sacrificial protective head overcoat, applying one or more final protective head overcoat layers to cover each final trailing edge topography and air bearing pattern and form the one or more sliders.
