PURPOSE:To increase the magnetic flux density of the titled recording medium and to further reduce the thickness of the thin film by forming the substrate with Mn or V, and forming the magnetic layer with a Co-base alloy. CONSTITUTION:The magnetic recording medium consists of the substrate layer formed on a substrate and consisting of Mn or V and a magnetic layer formed with a Co-base alloy contg. <=35atom% Ni or <=20atom% Cr or <=45atom% total amt. of Ni and Cr. When a layer consisting of an element selected from Si, Ge, and Ti is provided between the substrate layer and the substrate, uniform crystal growth of the metal in the substrate layer is promoted. With this constitution, the magnetic flux density is increased, and the recording medium with a thin film can be obtained.
