Abstract:
A method for fabricating a honing head, having an array of depressions, used for burnishing a planar disc to be used in data recording and reproduction, using photolithographic techniques, comprising the steps of:applying a photoresist material to a bearing surface in a pattern defining an array of planar geometries; exposing the bearing surface to a light source, creating a mask in the form of an array of planar geometries, wherein the array of planar geometries are unmasked and define the surface topography of the bearing surface; exposing the head to plasma rays, wherein the unmasked array of planar geometries will be milled to a desired depth; and applying a diamond-like-carbon coating to all surfaces of the head.
