Abstract: The discs comprise a non-magnetic base material, a magnetic layer applied thereto on at least one side, based on a magnetic material finely distributed in an organic binder matrix, and a friction-reducing carbon layer, situated on the surface of the magnetic layer.

Abstract: The recording tape or carrier consists essentially of a non-magnetic base and a thin layer of metallic and magnetic material deposited on the top, with a surface layer and a protecting layer of amorphous carbon which contains some hydrogen. This surface layer is produced in a vacuum chamber by means of a ''sputtering'' process with a carbon target.

Abstract: For cleaning or smoothing the surface of a material web (2), the latter is passed over at least one blade (4), the web being pressed against the blade edge (10) by means of a vacuum. The opening (9) of a vacuum chamber (8) formed next to the blade (4) is adjustable with respect to the blade edge (10), so that different flows and forces can be set.
