摘要：
The magnetic recording medium of the present invention comprises a ferromagnetic metallic thin film formed on a non-magnetic support, whereby a protective layer is formed on the ferromagnetic metallic thin film, said protective layer contains at least one type of thiouracil cyclic compounds having hydrocarbon group and at least one type of fluorine compounds having hydrocarbon group, or at least one type of tetrazaindene cyclic compounds and at least one type of fluorine compounds having hydrocarbon group, and no rusting occurs even when it is repeatedly run.
