A magnetic recording medium suitable for high density recording having improved erasing characteristics is produced by a method comprising the steps of forming an under coat layer containing an electrically conductive material on at least one surface of a substrate, applying a magnetic paint containing hexagonal system ferrite magnetic powder on the under coat layer and drying the applied magnetic paint to form a magnetic layer having a thickness of not larger than 0.7 .mu.m.

Magnetic recording medium

A magnetic disc which comprises a non-magnetic support substrate and a magnetic layer thereon consisting of a magnetic coating comprising ferromagnetic powder, a binder, an aliphatic acid ester having a melting point not higher than 10.degree. C. and an aliphatic acid ester having a melting point from 15.degree. to 60.degree. C., the magnetic coating having improved lubricity and durability.
