ABSTRACT:
A magnetic field orientation for producing a magnetic recording medium is made by using plural moving magnet which are driven in a direction parallel to the running direction of a nonmagnetic base film having a magnetic layer thereon; thus the time period during which the magnetic particles in the magnetic paint coated on the nonmagnetic base receive orientation can be varied independent from coating velocity.
