Abstract: The invention relates to a process for the production of magnetic recording media by preparing a dispersion of anisotropic magnetic materials in the solution of an organic binder using dispersants and further conventional additives, applying the dispersion as a layer on a nonmagnetic substrate and solidifying the the applied magnetic layer, the cylindrical milling container used being provided with an anchor-like or spiral stirrer and being filled with grinding media whose specific gravity is lower than that of the magnetic material.
