The magnetic recording medium has satisfactory sensitivity and frequency characteristics, freedom from output variation in the high-frequency region, and excellent running properties at ordinarily temperature and ordinary humidity with a reduced rate of running stop.

Magnetic recording medium

A method of making a substrate for a magnetic recording medium comprises the steps of applying a radiation-polymerizable compound at least to one surface of a base sheet, closely contacting a surface of a transfer member with a surface of a coating layer thus formed of the radiation-polymerizable compound, exposing the coating layer to a radiation from the side of the base sheet or the transfer member, whichever is permeable to the radiation, and separating the transfer member form the surface of the coating layer. The surface of the transfer member is adjusted so that the arithmetical mean deviation at a cut-off value of 0.25 mm and at a measuring length of 80 mm is within the range of 0.001 .mu.m to 0.050 .mu.m, and the ratio of the maximum height at a cut-off value of 0.25 mm and at a measuring length of 20 mm to the arithmetical mean deviation is within the range of 5:1 to 20:1.
