ABSTRACT:
The present invention discloses texturing of the slider air bearing surfaces of the magnetic heads in disk drives to reduce stiction that retards take-off and displaces critical lubricant in a magnetic head system. One embodiment of the present invention utilizes nonuniform etching of chemically identical components of a ferrite slider material due solely to random crystal orientation relative to the exposed surface. Another embodiment of the present invention utilizes a photoresist of a type used in making printed circuit boards, to form a pattern. Subsequently, the surface may be etched to form the antistiction properties. A variety of controlled and reproducible patterns as well as a controlled depth of pattern may be utilized.
