Abstract
A manufacturing device of an optical recording medium having a plurality of recording layers formed on a substrate is provided. The manufacturing device includes a vacuum pre-treatment chamber(52), a plurality of recording layer forming chambers (54, 56) each for forming a recording layer by vapor-depositing an organic pigment material, a reflective layer forming chamber (58), and a vacuum post-treatment chamber (60). Each of the recording layer forming chambers has at least one recording layer forming unit (84, 86), and the reflective layer forming chamber has at least one reflective layer forming unit (88).
