摘要：
A magnetic recording medium comprising a substrate and a magnetic layer thereon, the magnetic layer
(a) being a continuous magnetic layer made mainly from iron oxides, and (b) having not less than 0.5 of ratio between perpendicular-to-plane residual magnetization and in-plane residual magnetization of said magnetic layer, M V 'M H . A process of manufactuing a magnetic recording medium comprising a substrate and a continuous magnetic layer made mainly from iron oxides formed thereon and having not less than 0.5 of ratio between perpendicular-to-plane residual magnetization, M v , and in-plane residual magnetization, M H , of magnetic layer: M V /M H , comprising causing particles to be component of said magnetic layer to fly and be deposited on said substrate.
