ABSTRACT:
A method of producing a magnetic recording medium comprises forming a magnetic layer by applying a magnetic film forming liquid onto a continuously running non-magnetic support, applying a magnetic field onto the magnetic film forming liquid before the magnetic film forming liquid has dried, and then drying the magnetic film forming liquid. A non-magnetic undercoating layer is formed on the support simultaneously with the step of forming the magnetic layer by simultaneously applying to the support a non-magnetic undercoating forming liquid and the magnetic film forming liquid. The magnetic field is applied before both the magnetic film forming liquid and non-magnetic undercoating forming liquid have dried.
