Abstract: Magnetic recording media contain a nonmagnetic substrate and a magnetizable layer, the magnetizable layer containing ferromagnetic pigments and a system of polymeric materials, wherein the system of polymeric materials containsa) from 3 to 35% by weight of a polymer containing ionic or ionogenic groupsb) from 5 to 97% by weight of a polymer XIV which contains basic groups, and has a molecular weight of from 30000 to 2000000.

Abstract: The heat sealing film and a magnetic transfer strip contain an adhesive layer comprising thermoplastic, immiscible binder components. One component is spherical, amorphous and embedded in finely distributed form in a homogeneous layer of the other, highly crystalline components in such a way that the spherical component protrudes hemispherically from the layer. The spherical binder is a glassy solid up to at least 60.degree. C. and above 80.degree. C. is plastically deformable. The hemispheres protruding from the adhesive layer produce a uniform, fine roughness of the surface. Both heat sealing film and magnetic transfer strip are nonblocking up to at least 60.degree. C. and heat-sealable at temperatures greater than 80.degree. C. The adhesive layer imparts to a magnetic recording medium a uniform thickness of the adhesive joint and a permanent, temperature-resistant adhesive force.

Abstract: Flexible magnetic recording media consisting essentially of a web-like nonmagnetic substrate, a magnetic layer applied to one main side of the web-like substrate and a backing layer formed on the opposite main side of the substrate from a polymeric binder, at least one filler, at least one auxiliary pigment and a polyolefin having a spherical particle shape.

Abstract: Disk-shaped magnetic recording media essentially consisting of a flexible substrate, a thin ferromagnetic metal film applied to one or both sides and a protective or antifriction layer present on this metal film and essentially consisting of carbon, a process for the production of these recording media and information stores containing these recording media.

Abstract: Magnetic recording media consist of a flexible disk-shaped nonmagnetic base, a cobalt/chromium layer applied thereto and suitable for vertical recording, and a friction-reducing layer of amorphous carbon present on this alloy layer.
