ABSTRACT:
In forming a vertical magnetization type recording medium, a first soft magnetic film layer is formed on each side of a film-shaped support by vacuum deposition or sputtering at a temperature of 30.degree. C. or lower, a second soft magnetic film layer is formed on each of the first soft magnetic film layers, and a vertical magnetization film layer essentially containing Co-Cr is formed on each of the second soft magnetic film layers. The thickness of the first soft magnetic film layer on one side of the support may be made different from that of the first soft magnetic film layer on the other side so that curling of the recording medium is substantially eliminated.
