Abstract: A process and apparatus for the manufacture of magnetic recording media, in which, immediately before the magnetic dispersion is applied to a base, the dispersion is subjected to shear by means of a disc rotatably mounted in a housing, by introducing it at the center of rotation of the disc and forcing it through a gap formed between the face of the disc and the wall of the housing, which gap tapers toward the rim of the disc.

Abstract: Magnetic recording media in which, following application of the magnetic dispersion to a web of tape base material, the magnetic particles are oriented in a preferred direction and the magnetic dispersion is dried to fix the magnetic particles in their oriented position. To assist the orienting action of the orientation magnet, a blanket is located between the latter and the coating device, which blanket is caused to make sliding contact with the applied magnetic layer.

Abstract: Laminated magnetogram carrier consists of (1) flexible polyethylene terephthalate having a thickness of 4-36 mu m, (2) opt. a bond-promoting intermediate layer, and (3) a magnetic, image-registering layer consisting of a finely divided magnetic pigment in a binder. Layer (1) possesses an average surface roughness (Rz) of 0.05-0.20 mu m, and a max. point roughness (Rt) of is not >200 of the average surface roughness. Gives video signals having a low grass noise and a satisfactory mitte value. Percentage of reject carriers is greatly reduced.
