Magnetic recording medium |
摘要 |
A magnetic recording medium is disclosed which comprises a support and formed thereover a magnetic layer having a multilayer structure comprising at least two vapor-deposited metal films each made up of columns, each vapor-deposited metal film having a degree of column curvature of 20% or lower, and any of said vapor-deposited metal films which is closer to said support having a higher degree of column curvature than any of said vapor-deposited metal films which is closer to the surface. The magnetic recording medium enables high-density recording, is excellent especially in output characteristics and C/N characteristics, and has a balance between longitudinal-direction magnetic characteristics and vertical-direction magnetic characteristics.
