Ordinary optical disks need the resetting of recording conditions in the course of recording to cope with changes in ambient temperature, laser temperature, and medium's recording sensitivity. Optical disks for super-resolution reproduction which are intended to reproduce record marks smaller than the optical resolution, thereby increasing the recording density, need the resetting of recording conditions as well as the condition of super-resolution reproduction because the quality of reproduced signals depends largely on the power for super-resolution reproduction. The power for recording as well as the power for super-resolution reproduction is therefore changed in the course of test recording to detect the deviation from the optimum value of the recording condition to obtain the optimum recording power. In this case, it is also desirable to change the power for super-resolution reproduction in proportion to the power for recording.
