1. 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°

    to +30°

    , 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.
