ABSTRACT:
An optical information recording and reproducing device1irradiates initialization light L1to an optical information recording medium100having a recording layer101made of photopolymerization-type photopolymer in advance to bring about the photopolymerization or the photocrosslinking to perform the initialization processing, and condenses a recording light beam L2chaving a comparatively strong light intensity to a target position in the recording layer101and increases the temperature thereof to transubstantiate the target position to record a recording mark RM at the time of recording information, and condenses a reading light beam L2dhaving a comparatively weak light intensity to the target position and receives a returned light beam L3having a sufficient light amount reflected by the recording mark RM at the time of reproducing information, which makes it possible to reliably record the recording mark RM and stably read out the recording mark RM.
