| 英文摘要 | This invention relates to a semiconductor laser drive circuit which is used as a light source of an optical recording/reproducing apparatus using an optical disk. Upon recording whereby an output light of a semiconductor laser (1) is modulated by a recording signal (a), the output light of the semiconductor laser is detected as a monitor signal by a photo sensitive device (2), the peak value of this monitor signal is held by a peak-hold circuit (14), a differential control signal is obtained from an output of the peak-hold circuit and is fed back, and a photo control system to control the output light to a constant level is constituted, thereby controlling such that the output light of the semiconductor laser becomes a certain constant modulation amplitude. Even upon recording, the output light can be stably controlled within a wide temperature range even if the characteristic of the semiconductor laser changes with an elapse of time. Also, this drive circuit can be realized by a simple arrangement. |
