PROBLEM TO BE SOLVED: To provide a discrete track magnetic recording medium which prevents corrosion without degrading the recording/reproducing characteristics. SOLUTION: This magnetic recording medium has recording regions including patterns of a magnetic material corresponding to servo signals and recording tracks, non-recording regions including an oxide of the magnetic material formed between the recording regions, and a protective film formed on the surfaces of the recording regions and the non-recording regions, in which the protective film has a larger thickness on the recording regions than on the non-recording regions.
