METHOD AND MACHINE FOR MANUFACTURING STACKED MULTILAYER OPTICAL RECORDING DISK MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing machine of a multiplayer optical recording disk medium consisting of several signal recording/reproducing layers stacked by using light or heat, which can manufacture a disk having light transmissive layers of even thickness with less bubbles and wrinkles and form the reflector layers and recording layers using a general use sputtering machine and also with tilting stabilized after manufacturing.;SOLUTION: This invention includes a film forming process to form at least one or more reflector films and recording films on a first plastic disk base plate having grooves at least on one of its surfaces, a sticking process 310 to stick at least two light transmissive films on the first base plate, a transfer process 320 to transfer grooves on the light transmissive films, a curing process 350 to cure the transmissive films with ultraviolet ray, a stamping process 340 to stamp out the stuck transmissive films into discs, and a stock/transfer process 350 to stock the stamped optical recording media or to transfer them to the film forming process.;COPYRIGHT: (C)2002,JPO
