Title:
PRODUCTION OF OPTICAL RECORDING MEDIUM
Document Type and Number:
Japanese Patent JP3713773
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make it possible to execute the formation of intermediate films having a sure required thickness and having the thickness uniform in the respective parts and the formation of an information surface.
SOLUTION: A liquid resin is arranged on at least either of a substrate 1 constituting an optical recording medium or stamper 40 forming the information surface. Next, the optical recording medium is obtd. by a rotary spreading stage of the liquid resin 30 which aligns the substrate 1 and the stamper 40 across the liquid resin 30 and spreads the liquid resin 30 between the substrate 1 and the stamper 40 by integrally rotating the substrate 1 and the stamper 40 in this state.
