デイスクとの接触部分に集中して正確な複製に困
難を伴うばかりか、固化した樹脂が紫外線を遮つ
て接触部分の固化を困難にした。 Various methods have been proposed for duplicating video disc records that record video information at a high density, and a method using an ultraviolet curing resin has been proposed as a manufacturing method. In this manufacturing method, a liquid ultraviolet curing resin is applied to the surface of the master disk and cured by irradiating it with ultraviolet light. However, in the case of such a manufacturing method, because the applied resin solidifies while undergoing a volume change from the surface due to irradiation, all the distortion due to the volume change is concentrated in the area in contact with the master disk, making it difficult to reproduce accurately. Not only was this difficult, but the solidified resin blocked ultraviolet rays, making it difficult to solidify the contact area.
そこで、本発明は、マスターデイスクとの接触

んど接着しない材料を用いるものとする。 Hereinafter, the present invention will be explained according to an illustrative embodiment. In this embodiment, a glass master 2 on which a photoresist film 1 has been formed is exposed and irradiated with optically modulated laser light, and a transparent photoresist master 3 is formed by development processing.
In order to facilitate the peeling work in the photoresist master forming step a to form a resin master and the following resin master forming step, a thickness is applied to the surface of the photoresistor master 3.
A metal vapor deposition step b in which a thin silver vapor deposited film 4 with a thickness of 300 to 400 Å is formed, and a transparent resin plate 6 that becomes a substrate by applying an ultraviolet curing resin 5 (357 ultraviolet curing resin manufactured by Loctite) to the surface of this vapor deposited film 4. a resin master pasting step c in which the resin master is pasted, a resin master forming step d in which the resin master 7 is peeled off after solidifying the resin by irradiating ultraviolet rays from the glass substrate 2 side, and an ultraviolet curing resin 8 is pasted on the resin master 7. (manufactured by Toagosei Chemical Industry Co., Ltd.)
a duplicate disk attaching step e in which a transparent resin plate 9 is attached by applying UV3264), and a duplicate disk forming step f in which a duplicate disk 10 is formed by irradiating ultraviolet rays from the resin master 7 side to solidify the ultraviolet curing resin. Consists of. The vapor-deposited film 4 is sufficiently thin to allow ultraviolet rays to pass through, and both of the ultraviolet curing resins are transparent in a solidified state, and the ultraviolet curing resin 8 on the replication disk 10 side is highly resistant to the transparent resin plate 9. A material that adheres to the transparent master 7 but hardly adheres to the transparent master 7 is used.
上述せる如く、本発明によればマスタデイスク
