A magnetic recording medium includes a nonmagnetic granular layer that has a granular structure in which a plurality of nonmagnetic grains made of a nonmagnetic material are separated from one another by a Cr oxide. The magnetic recording medium further includes a magnetic granular layer that is formed on the nonmagnetic granular layer and has a granular structure in which a plurality of magnetic grains made of a magnetic material are separated from one another by a nonmagnetic material.
