<p>A vertical magnetic recording medium is provided with a magnetic recording layer having a granular structure containing Co, and an auxiliary recording layer, and in the vertical magnetic recording medium, noise of electromagnetic conversion characteristics is reduced. The vertical magnetic recording medium is provided with, on a nonmagnetic substrate, a first magnetic recording layer (20a) having a granular structure wherein a nonmagnetic grain boundary section is provided between columnar magnetic particles containing at least Co; a nonmagnetic layer (22) arranged on the first magnetic recording layer (20a); a second magnetic recording layer (20b), which is arranged on the nonmagnetic layer (22) and has a granular structure wherein a nonmagnetic grain boundary section is provided between columnar magnetic particles containing Co; and an auxiliary recording layer (24) arranged on the second magnetic recording layer (20b).</p> |
