    Abstract: A magnetic recording disk comprises a magnetic layer consisting of a binder and magnetic particles, a silicon substrate and abrasion-resistant material formed on the silicon substrate. The abrasion-resistant material is in the form of elevations which protrude from the silicon substrate and whose surface is coplanar with the surface of the magnetic layer. The abrasion-resistant elevations are formed on the substrate in a predetermined uniform distribution either after the surface of the substrate has been blanket doped and/or covered with a layer comprising aluminum as a main component, by tempering and optionally oxidizing; or after the surface of the substrate has been selectively doped, by etching off the undoped regions of the surface of the substrate.

    Abstract: The lacquer contains a white pigment with a grain size bigger than all other pigments in the lacquer. This white pigment either changes its color itself under the influence of heat, or under the influence of heat with a substance coacting with the pigment. Preferably used is a natural or synthetic hard polymer, or in particular, calcium carbonate with an admixture of approximately 10% sodium glycolate.

    Abstract: The method of producing pyrolytic SiO2 on the surface of a substrate comprises mixing SiH4 and NOCl in an atmosphere of carrier gas, and passing the gas mixture over the heated substrate. With this process, precipitation of SiO2 on the walls of the reaction chamber is avoided.
