Abstract: PURPOSE:To improve the adhering efficiency of ferromagnetic metal by filling oxygen gas in a vacuum tank, arranging a coil in the course of a ferromagnetic metal vaporizing passage and flowing amplitude modulated wave or frequency modulated wave through the coil. CONSTITUTION:The numeral 24 designates a coil which is arranged in the course of vaporizing passage of ferromagnetic metal 23 between a back roller 19 and a vaporization source 22, and amplitude modulated wave or frequency modulated wave is energized by a power source 25. Accordingly, a DC voltage is applied to the back roller 19, and amplitude modulated wave or frequency modulated wave is flowed in the coil. Thus, several % of the metal 23 is ionized in the course of vaporization and is adhered to a strip 15. In this case, the speed of adhering the metal 23 to the strip 15 is periodically varied by the operation of a signal flowing through the coil 24. Since oxygen is filled in a vacuum tank 11, the metal 23 and its oxide are alternately laminated on the surface of the strip 15 by the variation in the adhering speed, thereby obtaining a magnetic recording medium having high coercive force.
