Abstract
The present invention provides a technology which estimates the most suitable cure time which changes with the environment when recording a hologram and adjusts the cure time in real time, thereby enabling a suitable pre-cure or post-cure. When irradiating an optical information recording medium with cure light, the light transmitted from the optical information recording medium is detected by a detector and the irradiation time is adjusted by continuing irradiation until the intensity of the transmitted light detected exceeds a prescribed reference value.
