Light receiving element circuit and optical disk drive |
摘要 |
According to one embodiment, a plurality of light receiving elements photoelectrically convert light signals having information signals, respectively. A plurality of first amplification circuits amplify currents of electric signals from the respective light receiving elements. A selecting section selectively outputs one of signals amplified by the plurality of first amplification circuits. A second amplification circuit amplifies a voltage of the signal output from the selecting section, and supplies the signal to the outside.
