摘要：
A thin metallic layer type magnetic recording medium having thin metallic layers in a structure comprises a layer in which a tilt angle of a metallic particle direction to the normal line to said substrate gradually increases depending upon an increase of a distance from said substrate; and a layer in which a tilt angle of a metallic particle direction to the normal line to said substrate gradually decreases depending upon an increase of a distance from said substrate.
