| 英文摘要 | A semiconductor laser driving method, which is usable in an optical disc apparatus, for example, makes it possible to use a semiconductor laser in a low noise condition when the semiconductor laser is RF-modulated, by driving the semiconductor laser under a conditions where the average optical output is offset from peaks appearing in a curve representing the relative intensity of noise to average optical output characteristics of the semiconductor laser. More specifically, RF modulating conditions (frequency, amplitude and waveform) are selected so that the peaks do not enter the range of P-0.5 mW relative to the practically used average optical output P* for example. |
