    摘要： A magnetic recording medium is disclosed which is excellent in video and audio signal output as well as in S/N ratio. The recording medium comprises first and second magnetic layers provided on a support in this order from said support and the first magnetic layer has a SFD value of from 0.38 to 0.60 and the second magnetic layer has a SFD value of from 0.30 to 0.45, wherein SFD is defined as follows:SFD=.DELTA.H/Hcwhere .DELTA.H is a half-width of magnetic field at the extreme value of differential coefficient of a magnetic induction-magnetic field hysterisis curve, and Hc is a coercive force of a magnetic material.
