摘要： A film type multilayer magnetic recording medium comprised of a film applied to a substratum in which coating film needle-shaped magnetic grains are orientated with their longitudinal axes perpendicular to the film surface in a multilayer state and having a film thickness of 1.1 to 2.0 times the average length of the grains, has an excellent property, because the angular ratio (Br Bs) of both horizontal and vertical components respectively are 0.6 or more. As a result, it is possible to attain a high density recording. The film type multilayer magnetic recording medium of the present inventions is manufactured by applying a fluid film forming material, in which neddle-shaped magnetic grains are dispersed to form a coating film having the thickness of 1.1 to 2.0 times the average length of the magnetic grains on a substratum, and then drying or hardening the film forming material in a magnetic field orientated perpendicularly toward the film surface.

摘要： 57 An apparatus and method are provided for magnetically disorienting magnetic particles in a magnetic layer of a web coated recording medium that is designed to be used in the manufacture of flexible disks. Disorientation is achieved by subjecting the particles in a fluid pigment carried on a linear web to a rotating magnetic field that projects into the plane of the fluid layer and is rotated about an axis perpendicular to the plane. The interaction of the rotating field with the magnet particles also has a smoothing effect on the outer surface of the magnetic layer.

摘要： A magnetic printing master prepared by:
1. coating a layer on a flexible support sheet; 2. prestructuring the coating in a periodic manner, and 3. laminating the CrO 2 -coated sheet onto a second adhesive-coated, support sheet, such as 3-7 mil polyester. The resulting film may be imaged by selective demagnetization and toned. Known transfer technology may then be used to provide a printing plate.

摘要： @ An electron beam irradiation apparatus comprising an electron beam source which is capable of generating electron beam and irradiating it in one direction, a first magnet member having a through hole and being disposed allowing the electron beam irradiated from said electron beam source to pass therethrough, a second magnet member which is disposed opposing to the first magnet member through a gap which allows a target to pass therethrough and has the polarity different from that of the first magnet member, a target supporting/shifting means which allows the target to pass through said gap and cooling means which cools said both magnet members in which a base material coated with a paste of magnetic particles is used as the target and vertical orientation of the magnetic particles and hardening of the paste can be simultaneously conducted.

摘要： The invention concerns a device for applying magnetic dispersions to non-magnetic substrates, the device being optimised by a magnet which is disposed opposite the discharge slot of an extrusion caster and is covered at an angle by a soft iron bar. The inlet edge of the soft iron bar is disposed practically opposite the discharge slot. A curved guide member in front of the soft iron bar improves the sliding behaviour of the substrate during application.

摘要： The invention concerns a method and device for producing magnetic recording media with a disoriented particulate magnetic layer applied to a non-magnetic layer carrier. For the purpose of disorientation, the magnetic layer containing magnetically anisotropic pigments, after being applied to the layer carrier, is first oriented perpendicular to the plane of the magnetic layer by means of a unipolar magnetic field constant in time. The still-liquid magnetic layer is then passed into a field-free space where the layer is disoriented before it starts to dry. The device according to the invention comprises a magnetic arrangement which is mounted in a mirror-symmetrical manner either side of the layer carrier and generates a unipolar magnetic field oriented perpendicular to the plane of the magnetic layer. According to the invention, disc-shaped magnetic recording media can be produced from particulate magnetic layers without any portion of the reading voltage amplitude being dependent on orientation.
