Title:
OPTICAL INFORMATION RECORDING DEVICE AND METHOD FOR RECORDING OPTICAL INFORMATION
Document Type and Number:
WIPO Patent Application WO/2016/117101
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a suitable optical information recording device and a method for recording optical information by performing sufficient pre-curing to improve the recording quality of a hologram and shortening the time needed for post-curing in order to achieve high-speed transfer and recording. The optical information recording device for recording information onto an optical information recording medium using holography comprises: a cure light source unit for emitting pre-cure light or post-cure light with mutually different wavelengths; and a control unit for controlling so as to irradiate the optical information recording medium with the pre-cure light or the post-cure light depending on whether the irradiation is before or after the recording. A method for recording optical information utilizes this optical information recording device.
