Abstract: [Problem] An object is to provide a perpendicular magnetic recording medium that can realize both improvement in crystal orientation and refinement of crystal grain size and can achieve a higher recording density and a higher SN ratio, and a method of manufacturing the same. [Solution] A perpendicular magnetic recording medium 100 of the present invention is a perpendicular magnetic recording medium 100 having a base plate 100, and a laminate film including a first ground layer 150a provided on the base plate 100, a second ground layer 150b provided on the first ground layer 150a, and a main recording layer 160 provided on the second ground layer 150b and containing a magnetic material having a granular structure, wherein the magnetic material which constitutes the main recording layer 160 contains a CoCrPt alloy, and a material which constitutes the second ground layer 150b contains an Ru—Co oxide alloy.

Abstract: A perpendicular magnetic recording medium is used for information recording of a perpendicular magnetic recording type. The perpendicular magnetic recording medium includes a substrate, a soft magnetic layer, an underlayer, and a magnetic layer having a multilayered structure including a plurality of magnetic layers. The soft magnetic layer, the underlayer, and the magnetic layer are formed on the substrate. At least one of the magnetic layers includes CoPt magnetic grains containing oxide. The oxide includes at least one material selected from the group consisting of SiO2, TiO2, Cr2O3, Ta2O5, WO3, CoO, and Co3O4.
