Abstract
PURPOSE:To protect the surface of a ferromagnetic metallic film against corrosive environment and to prevent the corrosion thereof by forming a protective layer of a metal contg. either of tungsten or molybdenum on the surface of the ferromagnetic metallic film. CONSTITUTION:The protective layer 3 contg. at least either of the tungsten or molybdenum is formed on the surface of the ferromagnetic metallic film 2 of a magnetic recording medium formed with the ferromagnetic metallic film 2 essentially consisting of Co on a nonmagnetic substrate 1. The protective layer 3 consisting of the acid salt, etc., of the cobalt and tungsten on the surface of the ferromagnetic metallic film 2 is chemically stable as a salt and is structurally dense. The ferromagnetic metallic film 2 is thereby effectively protected against the corrosion.
