Abstract

PURPOSE: To obtain a magnetic recording medium featuring the excellent video and audio characteristics by providing the magnetic layer containing the ferromagnetic powder, the nonmagnetic layer and the ferromagnetic metal thin film layer each onto the nonmagnetic substrate.
CONSTITUTION: Magnetic layer 7 composed of the ferromagnetic powder (such as Co content iron oxide) and the binder is provided on nonmagnetic substrate 6, and then nonmagnetic layer 9 and the ferromagnetic metal thin film (such as Co evaporation film) 8 are provided on layer 7. Thus the magnetic recording medium is obtained. Layer 9 is composed of the organic substances such as the epoxy, polyethylene terephtalate, etc. with its film thickness set preferably to 500W3000Å or so.
