ABSTRACT:
Embodiments of the invention provide an air bearing surface protection film having good corrosive resistance, electrical insulative property and mechanical wear resistance in the state of an extremely thin film. In one embodiment, an air bearing surface protection film having good corrosive resistance, electrical insulative property and mechanical wear resistance in a state of an extremely thin film is obtained by disposing a thin silicon nitride film having high density, high electric resistance, chemical stability and high adhesion with a substrate as a lowermost air bearing surface protection film and disposing a film comprising tetrahedral amorphous carbon and nitrogen as an uppermost air bearing surface protection film.
