The present invention provides an optical recording/reproducing apparatus which can record information on the whole plane of the optical disk with a stable quality, even when the temperature has largely changed during a recording standby period in an intermittent recording process. The present optical recording/reproducing apparatus reproduces the information from a recorded portion on which the information has been already recorded, to evaluate the signal quality of the reproduced information, and simultaneously detects a temperature in the apparatus to correct a recording power of a laser beam when restarting the recording, on the basis of the evaluation result and the detected temperature in the apparatus, during the recording standby period in the intermittent recording process.
