ABSTRACT:
A method of manufacturing a multilayered recording medium. A transmissive stamper with a depression protrusion contour contacts a protection layer on a supporting base. The transmissive stamper is then irradiated with ultraviolet rays to cure the protection layer and the transmissive stamper is subsequently removed. A recording layer is deposited on the cured protection layer. Further, another recording layer is deposited on the transmissive stamper. Next, an intermediate layer is formed on the recording layer deposited on the transmissive stamper and thereafter, the intermediate layer is attached to the recording layer on the cured protection layer. Then, the transmissive stamper is irradiated with ultraviolet rays to cure the intermediate layer. Thereafter, the supporting base is removed from the protection layer. These steps produce a multilayered optical recording medium.
