ABSTRACT:
A magnetic storage medium includes a substrate, a protective film, and a lubricant film. The substrate includes a magnetic body. The protective film is formed on the substrate and constituted by a carbon thin film having dangling bonds formed on a surface thereof. The lubricant film is coated on the protective film and bonded to some of the dangling bonds. An adsorption site ratio (density of dangling bonds/density of functional groups of lubricant film) which is a ratio of the density of the dangling bonds to the density of functional groups of the lubricant film exceeds 1.
