ABSTRACT:
The present invention provides a method for forming a carbon protective film and a method for producing a magnetic recording medium, that decreases the generation of particles in a plasma CVD apparatus thereby improving flatness of the surface of a carbon protective film, and also can manufacture a magnetic recording medium having high recording density and excellent recording/reproducing characteristics; a magnetic recording medium; and a magnetic recording/reproducing apparatus using the magnetic recording medium.
