摘要：
A magnetic recording medium comprising a nonmagnetic support having provided thereon a magnetic layer comprising ferromagnetic particles dispersed in a binder, said magnetic layer having therein or on its surface a fluorine-containing oligomer surfactant which has a side chain having a poly(alkylene oxide) structure, a side chain terminated with a perfluoroalkyl group, and a side chain derived from an ester of acrylic or methacrylic acid with an aliphatic alcohol.
