Abstract
A process for producing a magnetic head slider with at least one rail having an air bearing surface. The process includes the steps of disposing a non-metallic film on a work surface to be shaped of a magnetic head slider material so as to be in intimate contact with the work surface, patterning the non-metallic film disposed on the work surface into at least one predetermined rail shape, shaping the work surface of the magnetic head slider material utilizing the patterned non-metallic film as a mask, and stripping off the patterned non-metallic film utilized as a mask which remains on the work surface of the slider material so as to provide at least one shaped slider rail of the magnetic head slider.
