Air bearing surface of head core slider, and method of manufacturing it.

摘要

The present invention discloses texturing of the slider air bearing surfaces (18a,18b) of the magnetic heads in disk drives to reduce striction that retards take-off and displaces critical lubricant in a magnetic head system. One embodiment 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 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 anti-striction properties. A variety of controlled and reproducible patterns as well as a controlled depth of pattern may be utilized. <IMAGE>
