PURPOSE:To obtain a magnetic recording medium having a high recording density and high reliability by including a lubricant inside the magnetic recording film and a protective film, and providing the thin film of the lubricant on the protective layer. CONSTITUTION:The magnetic recording layer consisting of a metallic magnetic alloy is formed on a substrate, and the protective film is formed on the magnetic recording film. The magnetic recording film and the protective film internally contain a lubricant, and the thin layer of the lubricant is provided on the protective film. Consequently, when pores exist on the magnetic recording film and the protective film, and the lubricant exists in then, the internal lubricant compensates the reduction of the lubricant layer on a surface according to the reduction of the lubricant layer on the surface. Thus, the magnetic recording medium for the high density recording having excellent durability and corrosion resistance can be obtained. |
