Title:
OPTICAL DISK ULTRAVIOLET IRRADIATING DEVICE AND OPTICAL DISK ULTRAVIOLET IRRADIATING METHOD
Document Type and Number:
WIPO Patent Application WO/2005/086150
Kind Code:
A1
Abstract:
An optical disk ultraviolet irradiating device effectively using electric power and having a long life and an optical disk ultraviolet irradiating method are disclosed. The optical disk ultraviolet irradiating device (14) for irradiating and curing an ultraviolet radiation-curing resin (A) applied to a disk substrate (D) with ultraviolet radiation by means of an ultraviolet irradiating unit (143). The ultraviolet light source of the ultraviolet irradiating unit (143) is an ultraviolet light-emitting diode (R). Since the ultraviolet light-emitting diode (R) is used as the ultraviolet light source, it is not necessary to generate visible and infrared lights unlike conventional xenon lamps. That is, only the ultraviolet radiation to cure the ultraviolet radiation-curing resin is applied, the power consumption needed to light emission of the light source can be reduced. The life of the ultraviolet light-emitting diode (R) is long, the number of replacements can be small, and the operation rate is improved.
