An optical disk (10) of the present invention has a substrate (11) included anresin-impregnated paper, in which resin is impregnated into paper, or resin-coated paper,nin which the paper surface is coated with a resin, and a recording layer (13) formed on atnleast one side of the substrate (11). This type of optical disk (10) has performance equalnto that of conventional optical disks and has a minimal effect on the environment duringndisposal. In addition, a manufacturing method of an optical disk of the presentninvention has a recording layer sheet fabrication step in which a recording layer sheet isnfabricated by forming tracks on a recording layer base material,nand a recording layer sheet lamination step in which a recording layer (13) included thenrecording layer sheet is provided on a substrate (11) included resin-impregnated paper ornresin-coated paper by laminating the recording layer sheet with the resin-impregnatednpaper in which a resin is impregnated into paper or the resin-coated paper in which thensurface of the paper is coated with a resin. This type of manufacturing method of annoptical disk allows optical disk (10) to be produced inexpensively. |
