ABSTRACT:
A chemically adsorbed film containing fluorocarbon groups is formed on an optical recording medium. Thus, an excellently water- and moisture-proof optical recording medium can be obtained. The optical recording medium is obtained by forming a chemically adsorbed film composed of fluorocarbon chain surface active material. The chemically adsorbed film is chemically bonded via siloxane covalent bonds. In the method of manufacture, an optical recording medium, e.g., an optical recording 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 group at the other end in a non-aqueous solvent or a gaseous phase condition, thereby chemically bonding the chlorosilane-based straight chain surface active material to the surface of the substrate via covalent siloxane bonds.
