    Abstract: PURPOSE: To obtain the titled magnetic recording medium having excellent traveling stability and resistance to wear and corrosion by using a perfluoroalkylcarboxylic acid ester and naphthols as a protective layer.
    CONSTITUTION: A ferromagnetic metallic thin film is formed on a nonmagnetic carrier, and the protective layer consisting essentially of a perfluo roalkylcarboxylic acid ester and naphthols is coated on the ferromagnetic metal lic thin film to obtain the medium. The perfluoroalkylcarboxylic acid ester to be used is expressed by the formula, C
    n F
    2n+1 COOR (where n is a 6W10 integer and R is a 1W25 C hydrocarbonic group), and can be easily synthesized by the reaction of a perfluoroalkylcarboxylic acid with the corresponding alcohol. α-naphthol, etc., can be exemplified as the naphthols to be used. The compounding ratio by weight of the perfluoroalkylcarboxylic acid ester to the naphthols is preferably controlled to 10/2W10/10.
