A magnetic recording medium having a magnetic layer on a non-magnetic support, whereby an organic fluorine compound given by the following general formulae (1) or (2) is formed on said magnetic layer:l formula (2) where Rf1, Rf2 and Rf3 each represents a fluoroalkyl group, Y1, Y2 and Y3 each represents -O-, -OCO-, -COO, -NHCO-, or -CONH-and may be the same or different; R1 represents =CH2, =CH(CH2)kCH3, or =CHCH=CH2, and k is a number from 0 to 2; R2 and R5 each represents H, and R2 is not present in case the carbon to which R2 is bonded has double bond. R3, R4 or R6 each represents H or a hydrocarbon group, which may have double bond. A, B and X each represents (CH2)k, and k is a number from 0 to 2, and b is a number of 0 or one or higher. Rf1, Rf2, Rf3, Y1, Y2, Y3, A, B, X, R4, R5, R6, k, n, and m may be the same or different, and these may be cis type or trans type.
