Abstract
An apparatus for producing a substrate sheet for optical recording media includes a device for continuously forming an ultraviolet-curable resin layer on at least one of i) a roll stamper having thereon a preformat pattern corresponding with preformatting information and ii) a substrate sheet; a means for bringing the substrate sheet into close contact with the roll stamper having the ultraviolet-curable resin layer; a device for curing said ultraviolet-curable resin layer to fix it on the substrate sheet; a device for peeling from the roll stamper the substrate sheet having the cured ultraviolet-curable resin layer; and a device for removing an ultraviolet-curable resin remaining on the surface of said roll stamper, provided after the means for peeling the substrate sheet.
