ABSTRACT:
A magnetic recording medium produced by treating a magnetic recording medium which comprises a non-magnetic substrate and a magnetic layer formed on said substrate in an atmosphere kept at a temperature of at least 50.degree. C., with applying a tension of 1 gf. or less per 10 mm width to said magnetic recording medium in a treating time which is in a range on or above a line having a slope of at least 5000 in terms of .DELTA.ln(L)/.DELTA.(1/T) and passing a point of 0.5 second at 100.degree. C., when ln(L) is Arrhenius plotted against an inverse of an absolute temperature T (1/T), which medium has suppressed change of magnetic properties with time and improved corrosion resistance.
