(57) [PROBLEMS] To reproduce a magnetic recording medium using fine hexagonal ferrite using an MR head, which has a short wavelength output and good C / N and stable recorded magnetization. To provide a magnetic recording medium and an effective recording method for the same. In a magnetic recording medium, a nonmagnetic layer in which nonmagnetic powder is dispersed in a binder is provided on a support, and a magnetic layer in which ferromagnetic powder is dispersed in the binder is further provided. Plate diameter is 10-30 nm, coercive force Hc is 135-400k A magnetic layer containing hexagonal ferrite powder that is A / m and the temperature coefficient of Hc at 25 to 75 ° C. is −0.16 to −0.44 (kA / m) / ° C. A characteristic magnetic recording medium. A recording method in which when recording a magnetic signal on the magnetic recording medium, magnetic recording is performed while heating the recording portion and the front thereof. |
