| 英文摘要 | An output voltage of a cathode driving type semiconductor laser driving circuit is made minimum, power consumption of a driving circuit section is suppressed, and heat generation of an optical head or an optical disc device is reduced. In addition to the conventional constitution, the semiconductor laser driving circuit permits the output voltage of the semiconductor laser driving circuit to be at a prescribed level by measuring a cathode voltage (Vout) of a semiconductor laser (1) and controlling an anode voltage (Vld) so that the cathode voltage (Vout) is at the prescribed level, reduces power consumption of the driving circuit and suppresses temperature increase of the optical head or the optical disc device to be minimum. |
