Magnetic recording medium |
abstract |
PROBLEM TO BE SOLVED: To be manufactured at a low cost with excellent productivity, and even when combined with GMR head reproduction, has high output, low noise, high S / N ratio, and excellent high density characteristics. To provide a magnetic recording medium excellent in recording stability. A magnetic recording medium in which a magnetic layer in which hexagonal ferrite is dispersed in a binder is provided on a nonmagnetic support and a signal having a recording wavelength of 0.1 to 0.3 μm is recorded. Is 3 × 10 −18 to 10 × 10 −18 ml, and the perpendicular magnetization demagnetization represented by the following formula after DC magnetization in the vertical direction and storage in a 60 ° C. environment for 24 hours is 3 or less. A magnetic recording medium characterized by the above. Perpendicular magnetization demagnetization = residual magnetic flux density after storage (Br) / residual magnetic flux density before storage (Br) [Selection figure] None |
