Abstract
A magnetic recording medium such as an audio-tape or a video-tape comprising a flexible support and a magnetic recording layer provided on one surface of said support, which is characterized in that the total of the thickness of said magnetic recording layer (dM) and the thickness of said support (dB), namely dM plus dB, is not larger than 14 .mu.m; the ratio of the thickness of said magnetic recording layer (dM) to the thickness of said support (dB), namely dM/dB, is in the range of 0.6-1.0; and said magnetic recording medium has F-3 tensile strength in the range of 6.0-8.5 kg/mm.sup.2.
