ABSTRACT:
A magnetic recording medium which has dynamic range (I) of 70 dB or more and dynamic range (II) of 45 dB or more in control of a thickness of a magnetic layer and magnetic characteristics wherein said dynamic range (I) is given as a difference between an output at 3% input level of third harmonic wave output at a wavelength of 237.5 .mu.m in the optimum bias recording by a head having a recorded width of 1 to 1.1 mm based on an output of the original signal and a reproduced output calibrated by auditory sense calibration at non-signal recording in the bias and said dynamic range (II) is given as a difference between a saturated output at a wavelength of 4.75 .mu.m under the same condition and the reproduced output calibrated by the A-curve calibration at non-signal recording in the bias.
