Abstract

The present invention relates to an improved method for preparing a magnetic recording method having excellent magnetic orientation comprising the steps of (1) dispersing ferromagnetic fine particles which are plate-shaped and which have an axis of magnetization perpendicular to the plates of the particles in a binder and (2) coating a magnetic coating layer on a non-magnetic support wherein the method comprises, after coating the magnetic coating layer and before drying it, subjecting the surface of the magnetic layer to a magnetic field from the direction perpendicular to the support to produce a magnetic orientation while contacting the surface of the magnetic layer with a flexible smoothening sheet.
