Abstract: PROBLEM TO BE SOLVED: To improve S/N of a reproduction signal by reducing amplifier noise of a reproduction signal detecting system without complexing an optical system. SOLUTION: In a PDIC irradiating an optical disk with one beam and performing photoelectric conversion of reflected light, when an optical disk being rewritable is played back, output signals of photodetectors O, P, Q, R are added by using a switch SW-P, switch SW-Q and switch SW-R as a terminal 1 respectively, this addition result (reproduced signal) is current-voltage-converted by a photoelectric conversion amplifier IV-amp 4A and outputted. Thereby, the used photoelectric conversion amplifier can be made to be 1/4 compared with the conventional case in which output signals of the photodetectors O, P, Q, R are photoelectric-converted by the photoelectric conversion amplifier IV-amp 1A to photoelectric conversion amplifier IV-amp 4A and added, amplifier noise of an reproduction signal detecting system is reduced and S/N of the reproduction signal can be improved without complexing the optical system.
