ABSTRACT:
A process for producing a magnetic recording medium includes coating a nonmagnetic substrate with a magnetic paint and applying a rotating magnetic field for orientation to the raw fabric with magnetic paint in a yet unsolidified state on the substrate, in which a magnetic field is applied to the above raw fabric so that the magnetic lines of force may pass from the back face to the front surface or from the front surface to the back surface of the raw fabric before application of the rotating magnetic field for orientation, thereby effecting preliminary orientation.
