| abstract | (57) [Summary]n[PROBLEMS] To significantly improve electromagnetic conversion characteristics, especially high-density recording characteristics. It has both good and excellent durability and high-density recording area. Recording media with significantly improved error rates in the To provide.nA substantially non-magnetic lower layer and a strong magnetic layer are formed on a support. Magnetic metal powder or ferromagnetic hexagonal ferrite powder A magnetic recording medium in which magnetic layers dispersed in a binder are provided in this order. In the recording medium, the magnetic recording medium has a surface recording density of 0. 2-2Gbit / inch Two Wherein the dry thickness of the magnetic layer is 0.05 to 0.25 μm and φm is 8.0 × 1 0 -3 ~ 1.0 × 10 -3 emu / cm Two And the resistance of the magnetic layer The magnetic force is 1800 Oe or more, and the surface of the magnetic layer Long wavelength spatial frequency intensity of 10 to 2 μm of roughness (I L ) And a short wavelength space of 1 to 0.5 μm of the surface roughness of the magnetic layer. Inter-frequency strength (I s ) Ratio (I L / I s ) Is less than 1.5 A magnetic recording medium. |
