摘要： A magnetic recording medium comprises:
a base film; a non-magnetic undercoat layer on said base film, said undercoat layer comprising a binder resin and non-magnetic acicular particles containing iron as a main component and from 0.05 to 50 % by weight of titanium, calculated as Ti, based on the total weight of the particles, which titanium is present within the particles; and a magnetic recording layer on said non-magnetic undercoat layer, said magnetic recording layer comprising magnetic particles and a binder resin.
