PROBLEM TO BE SOLVED: To provide a method for manufacturing a magnetic disk with which a magnetic disk equipped with a thin film carbon-based protective layer having enhanced adhesiveness between itself and a lubricating layer and sufficient mechanical hardness is obtained. SOLUTION: In the method for manufacturing the magnetic disk: an adhesion layer 2, a soft magnetic backing layer 3, an underlayer 4, a nonmagnetic intermediate layer 5, a magnetic recording layer 6, a carbon-based protective layer 7, and a lubricating layer 8 are sequentially formed on a substrate 1, wherein nitriding treatment is conducted to the carbon-based protective layer 7 by using a mixed gas of gaseous nitrogen and a rare gas having ionization energy larger than that of the gaseous nitrogen after deposition of the carbon-based protective layer 7.
