According to one embodiment, a method of manufacturing a magnetic recording medium includes depositing a magnetic recording layer on a substrate, forming masks on areas corresponding to recording regions of the magnetic recording layer, partially etching the magnetic recording layer in areas not covered with the masks with an etching gas to form protrusions and recesses on the magnetic recording layer, modifying the magnetic recording layer remaining in the recesses with a modifying gas to form non-recording regions, and forming a protecting film on an entire surface.
