The magnetic recording medium comprising a magnetic layer comprising a ferromagnetic powder and a binder on a nonmagnetic support, wherein a photosensitive layer comprising an organic dye and a nonmagnetic pigment is provided between said nonmagnetic support and said magnetic layer, said magnetic layer has an optical transmittance α equal to or higher than 30 percent at an absorption peak wavelength of said organic dye, and a product Br·δ of a residual magnetic flux density Br and a magnetic layer thickness δ ranges from 0.005 to 0.05 T·μm. The magnetic recording medium comprising a nonmagnetic layer comprising a nonmagnetic powder and a binder and a magnetic layer comprising a ferromagnetic powder and a binder in this order, wherein a photosensitive layer comprising an organic dye and a nonmagnetic pigment is provided between said nonmagnetic layer and a magnetic layer, and said magnetic layer has an optical transmittance equal to or higher than 30 percent at an absorption peak wavelength of said organic dye. By jointly providing an optical recording layer and a magnetic recording layer on the same surface of a support, recording capacity is improved and outputs of magnetic recording signals and optical recording signals and high S/N are obtained. |
