ABSTRACT:
Magnetic recording media for perpendicular recording are produced by coating a non-magnetic substrate by a PVD method with a cobalt-containing, ferromagnetic metal layer which has magnetic anisotropy perpendicular to the plane of the layer, by a process in which the temperature of the substrate is increased by external heating during coating.
