Abstract
A magnetic head manufacturing method. In one embodiment, a wafer including magnetic head devices formed on the surface thereof are cut out into individual sliders. Photoresist is applied on the air bearing surfaces of the sliders and is then baked. The surface tension causes the photoresist at the peripheral regions of the air bearing surface to taper and become rounded or thinned. The air bearing surface is then uniformly dry-etched such that the peripheral regions of the air bearing surface are rounded in a tapered shape.
