ABSTRACT:
A perpendicular magnetic recording medium includes: a substrate; a soft magnetic film formed on the substrate; a non-magnetic film including an amorphous interlayer formed on the soft magnetic film and made from a metallic material selected from terbium, gadolinium, dysprosium, tantalum, hafnium, and combinations thereof, a buffer layer formed on the amorphous interlayer and having a face-centered cubic structure, and a seed layer formed on the buffer layer and having a hexagonal crystal structure; and a granular magnetic recording film formed on the seed layer.
