Abstract: Magnetic recording media are produced by dispersing pulverulent magnetic material in a mixture of a solvent, an organic polymer binder, a dispersant and other conventional additives, with the aid of a conventional dispersing apparatus and using a particular ceramic grinding medium, applying the resulting dispersion in the form of a layer on a base and then compacting the layer.
