Abstract:
1. A method for forming a micro-texture on an air bearing surface of a magnetic read/write slider, the method comprising: (a) positioning sliders arranged in arrays on a tray, each slider having a pole tip facing upward; (b) loading the tray into a processing chamber, which is then evacuated to a preset pressure; (c) introducing a processing gas containing oxygen into the processing chamber; (d) exposing the sliders to an etching means in the atmosphere of the processing gas to etch the surface of the slider so as to form the micro-texture composed of a plurality of clear two-step structures, wherein the step of the two-step structure has a height ranging from 10 to 50 angstroms and a distance between adjacent steps ranging from 0.2 to 3 micrometers.
