RECORDING DEVICE AND OPTICAL OSCILLATOR DEVICE |
摘要 |
A recording device that records information in an optical recording medium includes: a self excited oscillation semiconductor laser including a saturable absorber section to apply a bias voltage and a gain section to inject a gain current, and also emitting a laser light to record the information in the optical recording medium; a reference signal generation unit generating a master clock signal and also supplying an injection signal synchronized with the master clock signal to the gain section of the self excited oscillation semiconductor laser; and a recording signal generation unit generating a recording signal based upon the master clock signal and also applying the recording signal to the saturable absorber section of the self excited oscillation semiconductor laser as the bias voltage. |
