| 英文摘要 | A first current source applies a first current to an anode of a semiconductor laser, and a second current source either draws a second current from the anode of the semiconductor layer or supplies the second current to the anode of the semiconductor layer. A switched current source connected to the anode of the semiconductor layer selectively draws a third current from the anode of the semiconductor laser. The third current has a value corresponding to a difference between a peak value and a minimum value of a pulse current flow in the semiconductor laser during a recording operation. By drawing the third current from the anode of the semiconductor laser according to recording data, a high speed and high power recording operation can be effected. |
