Abstract: 1. A flexible magnetic recording medium which comprises a polyethylene terephthalate film as the base, a magnetic layer which is applied to one side of the base and consists of anisotropic magnetic material dispersed in an organic binder, and a conductive backing coating which is one the side of the base opposite to the magnetic layer and consists of non-magnetizable conductive and non-conductive solids finely dispersed in a binder, wherein the binder for the backing coating consists of a mixture of (a) from 20 to 45 parts by weight of a linear saturated polyester resin, (b) from 10 to 45 parts by weight of a polyurethane resin, (c) from 15 to 45 parts by weight of a polyphenoxy resin, and (d) from 5 to 30 parts by weight of a linear polyesterurethane resin.
