    Abstract: PURPOSE: To provide a method for producing a magnetic recording medium of a thin layer metallic layer type of which the desirable magnetic bearing on a tape surface coincides with an average recording direction. CONSTITUTION: At the time of depositing the vapor jet 7 of a magnetic material generated from an evaporator unit 6 housing the magnetic material in a reduced pressure chamber 1 by evaporation on a base 2, the center line of the evaporator unit is moved transversely in the axial direction of a drum with respect to the center line of the base surface and is arranged. The direction of the vapor jet is controlled by a shutter 9, the which the specific direction is imparted to the magnetic material deposited by evaporation.
