Japanese Patent JP2826728
Kind Code:
B2
Abstract:
PURPOSE:To decrease an initial error rate by coating an adhesive layer on substrates and sticking the substrates to each other in a vacuum atmosphere. CONSTITUTION:An optical recording medium having the tight sticking structure in which two sheets of the substrates 7, 9 are stuck to each other by disposing an information recording layer part 3 formed on one main plane of the substrate 7 on the inside surface is produced. A stage for coating the adhesive agent on the substrates and a stage for sticking the substrates to each other in the vacuum atmosphere are included in the above-mentioned production process. For example, the substrate 7 consists of a polycarbonate substrate 1, a silicon nitride film 2, a magneto-optical recording layer 3 and a silicon nitride film 4, and the substrate 9 consists of a polycarbonate substrate 6 and a silicon nitride film 8 and is tightly stuck to the substrate 7 via a UV curing type adhesive agent layer 5. Incorporation of air bubbles into the adhesive layer is thereby entirely obviated and the initial error rate in the case of reproducing the transmitted light is lowered.
