A magnetic recording medium and a method for the manufacture thereof are disclosed that are less likely to result in head crushing even if high-hardness slider materials are used, and which is formed with a carbon protective layer that has good anti-CSS characteristics. The carbon protective layer is formed using a sputtering gas mixed with methane at a greater amount than predetermined to form a carbon protective layer in which diamond bonds are present at a higher ratio than graphite bonds, and polymeric bonds are present to an adequate degree. A magnetic recording medium having such a carbon protective layer shows a very high durability in a CSS cycle test.
