(57) [Abstract] [Purpose] To obtain a metal thin film type magnetic recording medium excellent in running property, durability and storability. [Structure] In a magnetic recording medium having a ferromagnetic metal thin film on a non-magnetic support, a carbon film may be formed on the ferromagnetic metal thin film according to the following general formula (1) or general formula (2). It has a surface layer containing at least one of the fluorine compound represented, the surface layer further rust inhibitor, A magnetic recording medium which may contain an extreme pressure agent. Formula (1) Rf-Rh-COO- (R 1 O) n -R 2 General formula (2) Rf-Rh-COO- (R 1 O) n -R 3 -Rf However, Rf: (CF 3) a CF 3-a (CF 2) b, a: 1 to 3 a + b: 1 to 11, n = 1 to 8, R 1 : an alkylene group having 1 to 4 carbon atoms, R 2 : an alkyl group or alkenyl group having 2 to 26 carbon atoms, R 3 , Rh: Alkylene group or alkenylene group having 2 to 14 carbon atoms |
