PURPOSE:To obtain a magnetic recording medium having excellent high reproduction output by having he multi-layered structure of ''Permalloy'' films separated by >=1 layers of Ti films on a non-magnetic substrate, forming >=1 layers of the Ti films in the form of discontinuous films and forming a vertically magnetized Co-Cr film on the ''Permalloy'' films. CONSTITUTION:The ''Permalloy film'' 4 and the thin Ti film 6 are formed on the substrate 1 consisting of a heat resistant high polymer film, etc. by stopping once deposition then starting deposition again without depositing continuously the Ti over the entire layer to the entire film thickness. The ''Permalloy'' film 4 is again formed thereon and the vertically magnetized Co-Cr film is formed thereon. The ''Permalloy films'' are otherwise separated by the plural Ti films and the multi-layered structure is made by forming the ''Permally'' film 4 on the substrate 7, the Ti film 8 deposited continuously in the thickness direction, the film 4, the Ti film deposited again after stopping once the deposition in the thickness direction, the film 4 and the film 2. The magnetic recording medium which has excellent recording and recording characteristics and is suitable for high-density recording is thus obtd.
