PROBLEM TO BE SOLVED: To provide a magnetic recording medium, which prevents the occurrence of exfoliation between a magnetic layer and a protective layer, even if sliding is repeated, and also provide its manufacturing method. SOLUTION: A metal thin-film type magnetic recording medium 10 has a magnetic layer 2 and a carbon protective layer 4 on its nonmagnetic base material 1. In this case, the film thickness of a metal oxide layer 2a on the surface layer of the magnetic layer 2 is to at most 5 nm. The vacuum deposition of the magnetic layer, the etching of the metal oxide layer by an ion gun and the formation of a carbon protective film by a CVD method are carried out consecutively in an environment which isolated from external air.
