ABSTRACT:
A hard protective material and method for forming the medium having the formula C.sub.x N.sub.y. The medium may be formed as a protective film on a magnetic recording disk in a sputtering apparatus such as a magnetron apparatus. The amount of nitrogen in the film may be affected by controlling the collisions of the sputtered material between the target and deposition substrate by controlling the bombardment of the substrate by electrons. The films exhibit properties indicative of a textured morphology on a nanoscale which enhances the retention of lubricant overcoats.
