| titleOfInvention | Magnetic recording media |
| abstract | (57) [Problem] To provide a magnetic recording medium in which electromagnetic conversion characteristics, particularly high-density recording characteristics are remarkably improved and have excellent durability, and an error rate particularly in a high-density recording region is remarkably improved. To provide. In a magnetic recording medium having a magnetic layer formed by dispersing a ferromagnetic metal powder in a binder on a support, the magnetic recording medium has an areal recording density of 0.013 to 0.5 Gbit /. A magnetic recording medium for recording a signal of cm 2 (0.08 to 3 Gbit / inch 2 ), wherein the coercive force of the magnetic layer is (1.43 to 3 Gbit / inch 2 ). 2.86) × 10 5 A / m, and the ferromagnetic metal powder is composed of at least Fe and Co, and Al / (Fe + Co), the atomic ratio A of 3.0 to 10.0%, the atomic ratio B of the total of the rare earth elements / (Fe + Co) is 3.0 to 15.0%, and A magnetic recording medium, wherein the atomic ratio B / atomic ratio A, which is the sum of the rare earth elements / Al, is 1.3 to 2.0. |
