ABSTRACT:
The magnetic recording medium includes a seed layer and a magnetic recording layer formed on the seed layer. The magnetic recording layer is provided with a plurality of laminated layers and a noble metal layer. The laminated layer includes a transition metal element layer and a platinum group element layer. The noble metal layer is interposed between the laminated layers. The magnetic recording medium satisfies the relational expression 0<Y/X≦1.0, where X is the thickness of the seed layer, and Y is the sum total of the thickness of the noble metal layer in the magnetic recording layer.
