Optisches Informationsaufzeichnungsmedium, Verfahren und Klimatisierungssystem zu seiner Herstellung

摘要

Disclosed is a method for producing an optical disk (D) of the heat mode type comprising, on a substrate (202), a dye recording layer (204) capable of recording information by being irradiated with a laser beam, and a light-reflective layer (208) formed thereon. When a dye solution for forming the dye recording layer (204) is applied onto the substrate (202) while rotating the substrate (202), the number of revolutions of the substrate (202) is increased during the process in which the dye solution is applied to the inner circumferential side of the substrate (202). The dye recording layer (204) is formed on the substrate (202) by humidifying the process atmosphere to form the dye recording layer (204) by using water having a specific resistance of not less than 0.15 M OMEGA . Accordingly, it is possible to further efficiently achieve the uniform film thickness of the dye application surface and the formation of the application surface (dye recording layer) on which no error occurs. Thus, it is possible to provide the optical information-recording medium having good preservation performance as well.
