OPTICAL INFORMATION RECORDING DEVICE, OPTICAL PICKUP, AND METHOD FOR EMITTING LASER LIGHT |
摘要 |
An optical information recording device includes a semiconductor laser for emitting laser light, a light irradiation section for collecting the laser light and irradiating an optical information recording medium with the laser light, and a laser controller for supplying the semiconductor laser with a laser drive current wave in pulse form. The laser drive current wave has an oscillation current value that causes a relaxation oscillation of the semiconductor laser.
