ABSTRACT:
A magnetic storage medium includes a seed layer made of non-magnetic and amorphous Co—Cr—W, an intermediate layer having a crystalline structure, which is made of a non-magnetic material on the seed layer and has a c-axis oriented in a thickness direction of the seed layer in a hexagonal close-packed structure, and a recording layer made of mainly a magnetic material on the intermediate layer and having information magnetically recorded therein.
