| titleOfInvention | Magnetic recording medium |
| abstract | [57] [Summary] [PROBLEMS] To maintain a high C / N ratio and a low error rate even in a high-density recording area even when the recording environment and the reproduction environment are different, and excellent Providing a magnetic recording medium having running stability. A magnetic recording medium having a nonmagnetic layer containing nonmagnetic powder and a binder on at least one surface of a nonmagnetic support and a magnetic layer containing ferromagnetic powder and a binder in this order. The ferromagnetic powder is a ferromagnetic hexagonal ferrite powder having an average plate diameter of 5 to 40 nm or a ferromagnetic metal powder having an average major axis length of 20 to 100 nm, and the nonmagnetic layer and the magnetic layer of the nonmagnetic support are provided. The center surface average roughness of the obtained surface is 0.1 to 4.0 nm, the number of protrusions having a height of 273 nm or more is 0 to 10/100 cm 2 , and the MD direction and TD direction of the magnetic recording medium Expansion coefficient is −15 × 10 −6 to 15 × 10 −6 / ° C. and humidity expansion coefficient is −15 × 10 −6 to 15 × 10 −6 /% RH It is. |
