MULTILAYERED INFORMATION RECORDING MEDIUM AND PROCESS FOR PRODUCING SAID MULTILAYERED INFORMATION RECORDING MEDIUM, AND APPARATUS FOR PRODUCING MULTILAYERED INFORMATION RECORDING MEDIUM AND SCREEN CONSTITUTING SAID PRODUCTION APPARATUS FOR PRODUCING MULTILAYERED INFORMATION RECORDING MEDIUM

摘要

This invention provides a process for producing a multilayered information recording medium comprising two or more information recording parts and a resin layer disposed between the information recording parts, wherein the assembly is disposed on a signal substrate. The production process comprises a first step of forming a predetermined information recording part on one main side of the signal substrate and a second step of feeding a resin-containing coating material onto a screen comprising a coating region with a plurality of first holes and a removal region with a plurality of second holes, passing a part of the fed resin-containing coating material through the plurality of the first holes by sliding a squeegee on the screen to form a coating material layer onto the predetermined information recording part, and curing the resin contained in the coating material layer to form the resin layer. The production process is characterized in that the first step and the second step each are carried out by a predetermined number of times. In each second step, at least a part of the resin-containing coating material remaining, on the screen, uncoated onto the predetermined information recording part is passed through the plurality of second holes for removal from on the screen.
