Abstract: A magnetic head slider having a protective coating on the rails thereof, the protective coating comprising a thin adhesion layer and a thin layer of amorphous hydrogenated carbon. The protective coating is deposited on the air bearing surface of the slider after the thin film magnetic heads are lapped to a chosen dimension, but before the pattern of rails is produced on the air bearing surface. The protective coating protects the magnetic head during the rail fabrication process and in usage in a magnetic recording system protects the magnetic head from wear and corrosion damage.

Abstract: A thin film magnetic head (10), having a predetermined cut-off frequency is constructed of alternating first (22) and second layers (24), the first layers (22) comprised of a magnetic material and the second layers (24) comprised of a resistive material. The resistivity of the second layers (24) is chosen so that the head's cut-off frequency exceeds the head's required frequency response. The resistivity of the second layers is chosen to be considerably less than any level of resistivity which falls within the insulation regime.
