A magnetic recording film, which has excellent slip durability, is run-proof and wear-proof as well as self-lubricating, is obtained by forming a chemically adsorbed film composed of straight carbon chain surface active materials having different carbon numbers, the chemically adsorbed film being chemically bonded via siloxane covalently bonds. In the method of manufacture, a magnetic recording medium, e.g., a hard disk, is contacted with a solution which is made by dissolving a straight carbon chain surface active material having a chlorosilyl group at one end and a fluorocarbon or hydrocarbon group at the other end in a non-aqueous solvent, thereby chemically bonding the chlorosilane-based straight chain surface active material to the surface of the magnetic recording medium via siloxane covalently bonds.
