摘要

A magnetic recording medium has a construction in which on a non-magnetic support member are successively stacked a seed layer made of a non-magnetic material that is mainly composed of Cr, a keeper layer made of an NiFe-type soft magnetic material, an intermediate layer made of a non-magnetic material that is mainly composed of Cr and a recording layer made of a magnetic material that is mainly composed of Co.
