Within the vacuum atmosphere containing oxygen a cylindrical rotary can and an evaporation source are disposed in opposed relationship and in such a way that the normal line constructed at the center of the evaporation surface of the evaporation source will not intersect the axis of the cylindrical rotary drum. The beam of the evaporating ferromagnetic substance is directed to and impinged against the substrate transported along the rotary drum at right angles to the direction of transport thereof.
