Abstract
Provided is an information recording medium manufacturing device of the type in which a radiation curable layer-forming liquid resin is injected into a gap between a planar stamper carrying an information recording signal pattern to be transcribed and a planar flexible carrier member having at least one signal pattern carrying surface through means, for injecting the liquid resin, then the liquid resin is uniformly developed all over the surface of the carrier member by pressing a holding plate against the carrier member, and is set by irradiating radiant rays so as to form a transfer layer, thereby to obtain an information recording medium by separating from the stamper the carrier member united with the transfer layer. According to the present invention, the information recording medium manufacturing device further comprises means for shifting the stamper from a carrier member mounting section, sequentially through a radiation curable liquid resin injecting and pressing section and a radiant ray irradiating section, to a carrier member separating section, and then returning the same to the carrier member separating section.
