ABSTRACT:
A sputter-deposited wear-resistant protective coating for magnetic-recording alloy thin films is disclosed. The protective coating includes a protective layer and an interfacial adhesion layer. The protective layer is preferably titanium diboride or amorphous nitrided carbon, and the interfacial adhesion layer is preferably titanium, but can alternatively be other metals, such as zirconium or hafnium, which share characteristics similar to titanium. More broadly, the protective layer may be a nitride, carbide, or boride, or mixture thereof, of titanium, zirconium, hafnium, tantalum, vanadium, niobium, tantalum, chromium, molybdenum, or tungsten, and the interfacial adhesion layer may be the corresponding metal of the protective layer compound.
