ABSTRACT:
The magnetic recording medium has a magnetic layer of a ferromagnetic metal thin film over at least one surface of a non-magnetic base, in which a phosphoric monoester compound which is represented by R.sub.1 --OPO(OH).sub.2, a florine-containing fatty acid ester compound which is represented by R.sub.2 --COO--R.sub.3, and a fluorinated hydrocarbon in which some of the hydrogen atoms of a hydrocarbon having from 14 to 40 carbon atoms have been replaced by fluorine atoms, are present on the magnetic layer. R.sub.1 is a hydrocarbon group having from 8 to 26 carbon atoms. R.sub.2 and R.sub.3 are each a hydrocarbon group having from 8 to 26 carbon atoms, or a fluorinated hydrocarbon group in which some or all of the hydrogen atoms of a hydrocarbon group having from 8 to 26 carbon atoms have been replaced by fluorine atoms. R.sub.2 and R.sub.3 may be the same or different from each other. At least either one of R.sub.2 and R.sub.3 contains fluorine atoms.
