Abstract
A longitudinal magnetic coated recording medium comprises at least plane magnetic particles each having an easy magnetization axis perpendicular to the major surface thereof, preferably mixed with other particles, and dispersed in a magnetic film formed on a nonmagnetic substrate, having a orientation angle of -30.degree. to +30.degree.. A process for producing such a recording medium comprises the step of orienting the plane magnetic particles by applying at least a magnetic field approximately in parallel to the surface of the magnetic film.
Claims10
A longitudinal magnetic coated recording medium, comprising:
- a nonmagnetic substrate having a magnetic film formed thereon including a magnetic film plane;
- and
- plane magnetic particles, each having an easy magnetization axis perpendicular to a major surface thereof and dispersed in said magnetic film, the orientation angle of said particles being in the range of from-30.degree. to +30.degree., said orientation angle being determined by an angle where the ratio of residual magnetization to saturation magnetization Mr/Ms, is largest, and said orientation angle being defined as the angle between the magnetic film plane and said easy axis of magnetization.
