摘要 |
A magnetic recording medium suitable for high density recording comprising a substrate and a magnetic layer wherein the magnetic layer comprises a binder resin and ferrite magnetic powder comprising hexagonal system plate particles having such magnetic anisotropy that a magnetic anisotropy constant K1 corresponding to the vertical magnetic component and a magnetic anisotropy constant K2 corresponding to the horizontal magnetic component, both derived from Fourier analysis of a magnetic torque curve measured in a plane including the C axis of the hexagonal system, satisfy following equations: 0.5<K1/K2<5 and K1>0, The magnetic recording medium is suitable for use in high density recording. |
