MANUFACTURING METHOD FOR MULTILAYERED STRUCTURE TYPE OPTICAL RECORDING MEDIUM, MANUFACTURING DEVICE THEREFOR AND MULTILAYERED STRUCTURE TYPE OPTICAL RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To manufacture a multilayered structure type optical recording medium having a light transmission layer having uniform thickness and free from a bubble and a wrinkle.

SOLUTION: A manufacturing device for the multilayered structure type optical recording medium consists of a fixed part 31 provided with a core pin 35 and a supporting stand 34 vertically movably supporting the core pin 35 and a movable part 32 provided with a stamper 36, a nichrome ribbon 38 for heating the stamper 36 and a supporting stand 37 supporting them and is so constituted that melt adhesion of the light transmission layer and a recording layer on a substrate 11 fixed to the fixed part 31 to each other and groove transfer of the light transmission layer can be simultaneously performed by disposing a light transmissive thermoplastic resin 33 for forming the light transmission layer between the recording layer and the stamper 36 of the movable part 32.
