Abstract
PURPOSE:To prevent the generation of deposits to a head and to improve traveling durability by cleaning the surface of a protective layer, then providing a lubricating layer contg. an org. lubricant thereon. CONSTITUTION:The surface of the protective layer essentially consisting of carbon is cleaned by at least one selected from an alkaline detergent, neutral detergent and org. solvent at the time of providing a thin magnetic metallic film on a nonmagnetic substrate and providing the above-mentioned protective layer and the lubricating layer contg. the org. lubricant. One of >=two kinds selected from Cr, Mn, Mo, Nb, Ta, Ti, V, and W are incorporated as the additive metals into the protective layer and the content thereof is adequately specified in a 0.5-5% range.
