A process for producing a perpendicular magnetic recording medium comprises forming metallic nuclei or a seed layer on a non-magnetic substrate, and forming a soft magnetic under layer on the metallic nuclei or the seed layer by means of electroless plating. The soft magnetic under layer is formed while an external parallel magnetic field is applied to the non-magnetic substrate, and the substrate is rotated such that the substrate is maintained parallel to the parallel magnetic field.
