Information recording medium and method of manufacturing same

摘要

Two substrates (202) are simultaneously produced by an injection molding apparatus (12), and the injection-molded substrates (202) are alternately arranged and cooled by a cooling apparatus (14). The cooling apparatus (14) has a feed screw mechanism (250) for feeding the alternately arranged substrates (202) in one direction while cooling air is being applied to the substrates (202). An information recording medium which includes a substrate (202) is manufactured on a production line having a single injection molding apparatus (12) for simultaneously injection-molding two substrates (202) and four dye solution coating machines (38) for forming a dye recording layer (204) for recording information on each of the substrates (202).
