ABSTRACT:
A magnetic recording medium including a substrate, a first seed layer provided on the substrate, a second seed layer provided on the first seed layer and formed of the same material as that of the first seed layer, and a plurality of crystal layers provided on the second seed layer and including a magnetic recording layer. A normal to a crystal lattice plane preferentially oriented in a given direction in each grain composing one of the first and second seed layers is inclined from a normal to the upper surface of the substrate.
