ABSTRACT:
A method is described for preparing a magnetic recording medium comprising a non-magnetic support having provided thereon a magnetic layer containing a compound which is cross-linkable or polymerizable by radiation exposure, which comprises conducting a corona discharge treatment on a surface of a support, coating an aqueous dispersion of hydrophobic polymer on the surface of the support to form an undercoat layer, providing a magnetic layer on the undercoat layer, and exposing the magnetic layer to radiation.
