In a magnetic recording medium including a nonmagnetic substrate on which a magnetic layer, a protection film, and a lubricant film are successively tacked, the lubricant film is formed by quantitatively controlling an amount of a lubricant in consideration of a surface coverage ratio of the lubricant film relative to the protection film and an average thickness of the lubricant film. Preferably, the surface coverage ratio is selected between 0.55 and 0.985 while the average thickness is not smaller than 0.4 time an attenuation length of a photoelectron which is emitted from a predetermined element and which is attenuated in the lubricant film. To this end, an X-ray photoelectron spectroscopy is used to evaluate the lubricant film.
