    摘要： A method of producing a coated magnetic recording medium comprises a step of coating a nonmagnetic substrate with a magnetic paste layer mainly composed of acicular or granular magnetic particles and a resin binder, a spontaneous drying step for a specific period for inducing leveling of coated surface and spontaneous volatilization of solvent without applying magnetic field from outside after coating the magnetic paint, a first orientation step for dissipating the aggregated particles by a sudden change in magnetic field while inducing magnetic moment in magnetic particles by a strong DC magnetic field inside the coated surface and in a longitudinal direction of the medium for arraying the magnetic particles in the coated surface in the longitudinal direction, and a successive second orientation step for suppressing the magnetic repulsive force among particles while arraying the magnetic particles by a DC magnetic field in the coated surface in the longitudinal direction.

    摘要： A method and apparatus for producing a magnetic medium having a uniform orientation of magnetic particles over the entire width of the medium. Correcting magnets are provided which produce a magnetic field which linearizes the main orienting magnetic field in regions where the main magnetic field diverges outwardly toward edge portions of the medium. The correcting magnets may be disposed along either a straight or curved line diverging outwardly from the edges of the support of the medium, or they may be disposed parallel to the edges of the medium and having a varying magnetic field strength in the downstream direction of the medium with respect to its direction of conveyance.

    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.
