    Abstract: The magnetic recording medium consists essentially of a polymeric substrate, a coherent, magnetic thin metal film applied to the surface of the substrate by a PVD method and, if required, a protective layer formed on the thin metal film. In order to achieve a large residual induction component in the plane of the film, in particular high residual induction in the transverse direction, the thin metal film contains a noble gas or noble gas mixture, preferably argon. During the coating of the polymeric substrate with the magnetic metal or with the magnetic alloy, the noble gas is fed directly and preferably tangentially to the substrate surface at a specific noble gas flow of from 1.0.multidot.10.sup.4 to 6.0.multidot.10.sup.4. In the plane of the thin metal film, the ratio of residual induction in the longitudinal direction to that in the transverse direction is from about 0.9 to about 1.8.
