PROBLEM TO BE SOLVED: To provide an optical recording medium minimized in read-out error on both lands and grooves of a guide groove, and its recording/reproducing device. SOLUTION: This recording/reproducing device is constituted so that the information signal is recorded by photoirradiation on the optical information recording medium furnished with the projected-recessed guide grooves. By means of providing a selection part for selecting which surface of the lands or grooves of the guide groove is tracked, a polarity inverting device 18 of the tracking operated linked with the selection part, and a recording waveform setting part for setting the condition of photoirradiation simultaneously corresponding to each of the lands and grooves, the difference of the recording characteristics at the time of photoirradiation generated between the grooves and lands is compensated, then the recording of the signal minimized in distortion on both of them is attained. |
