Abstract: The invention relates to a process for the production of magnetic recording media by dispersing pulverulent, magnetic material in a mixture of solvents, organic polymer binders, dispersants and further customary additives in a stirred ball mill, followed by aftertreatment in a ball mill filled with grinding media, application of the resulting dispersion as a layer on a substrate and subsequent solidification of the layer.

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.
