Magnetic recording media, magnetic recording media fabrication method, and fabrication equipment |
摘要 |
A magnetic recording medium fabrication device includes a cooling drum around which a substrate runs while being cooled thereby, an ion gun arranged upstream to a vapor deposition station for kicking out particles absorbed on the plane of the substrate, a cooling body arranged between the cooling drum and ion gun for absorbing kicked out particles and a vapor deposition device for depositing a magnetic layer on the substrate at the vapor deposition station. The magnetic particles forming the magnetic layer that have residual magnetization vectors within +/-10 DEG of the easy axis direction including the magnetic anisotropy of the medium are greater than or equal to 70% and less than or equal to 90% of the total amount of magnetic particles.
