US 2008/0076845 A1 · Method of Manufacturing Optical Information Recording Medium

Abstract

The present invention provides a method of manufacturing an optical information recording medium having a cured layer of an ultraviolet-curable resin, including a treatment of irradiating a layer of the ultraviolet-curable resin with ultraviolet rays emitted from light emitting diodes having a light emitting wavelength peak of 380 nm or less to cure the ultraviolet-curable resin.

A method of manufacturing an optical information recording medium having a cured layer of an ultraviolet-curable resin, comprising a treatment of irradiating a layer of the ultraviolet-curable resin with ultraviolet rays emitted from light emitting diodes having a light emitting wavelength peak of 380 nm or less to cure the ultraviolet-curable resin,

wherein an end surface of the layer of the ultraviolet-curable resin is irradiated with ultraviolet rays emitted from a light emitting diode provided at an outermost circumferential side.

Dependencies are inferred from the claim text.
