PHOTOELECTRIC CONVERTING DEVICE, AND OPTICAL DISK APPARATUS AND ADJUSTMENT METHOD OF THE SAME

摘要

Provided is a photoelectric converting device including: first photoreceptors each converting a received main beam to a current; second photoreceptors each converting a received first sub-beam to a current; and third photoreceptors each converting a received second sub-beam to a current; first current-voltage converting circuits each converting the current converted by a corresponding one of the first photoreceptors to a voltage; current amplifying circuits each amplifying or attenuating the current converted by a corresponding one of the second photoreceptors; switching circuits each supplying one of the current amplified or attenuated by a corresponding one of the current amplifying circuits and the current converted by the corresponding one of the second photoreceptors; and second current-voltage converting circuits each converting a sum of the current supplied by a corresponding one of the switching circuits and the current converted by a corresponding one of the third photoreceptors to a voltage.
