PURPOSE:To provide the magnetic recording medium of a ferromagnetic metallic thin film type for obtaining a high reproduced output and high C/N ratio in a wide recording frequency range, i.e., from a long wavelength to a short wavelength. CONSTITUTION:A lower magnetic layer 2, a nonmagnetic intermediate layer 4 and an upper magnetic layer 3 are successively provided on a nonmagnetic base body 1 and the ratio t/d of the thickness (t) of the nonmagnetic intermediate layer and the thickness (d) of the upper magnetic layer is regulated to 0.1 to 0.3, by which the magnetic recording medium affording the high reproduced output and the high C/N ratio from the long wavelength to the short wavelength is provided. |
