ABSTRACT:
A coated metal-substrate disk for magnetic-recording applications is disclosed having a first coating selected from the group consisting of nitrides, carbides, or borides of titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, or tungsten, or the group consisting of aluminum nitride, silicon nitride, or silicon carbide on the metal substrate and a magnetic-recording material coating on the first coating. The first coatings are applied by evaporative reactive ion plating or by reactive sputtering.
