Abstract
A process for producing a magnetic recording medium is disclosed. The process comprises coating a magnetic coating composition comprising a ferromagnetic powder, a binder, and an organic solvent on either a non-magnetic support or a roller or band having a mirror surface to form a magnetic layer on the non-magnetic support or the roller or band, respectively, drying the magnetic layer so as to have a solvent content of from 0.05 to 10% by weight, contacting the magnetic layer on the support or the roller or band with a roller or band having a mirror surface or a non-magnetic support, respectively, and separating the magnetic layer from the roller or band. The resulting magnetic recording medium has smooth surface, high electromagnetic properties, and good durability.
