摘要： An optical recording medium discriminating apparatus discriminates at least two types of optical recording media having pits of different depths carrying recorded information. A light beam of a predetermined wavelength is caused to be incident to an optical recording medium, the amount of returning light therefrom is detected, and a read signal according to the detected amount of returning light is produced. The amounts of light in two areas, line-symmetrical to each other in the tangential direction of a track consisting of a sequence of pits, are detected from the amount of returning light, and a push-pull signal corresponding to a difference between the amounts of light in the two areas is produced. A phase difference between the read signal and the push-pull signal is detected, to discriminate the type of the optical recording medium is discriminated. In another optical recording medium discriminating apparatus, the amounts of light in two areas, line-symmetrical to each other in the tangential direction of a track consisting of a sequence of pits, are detected from the amount of returning light from the optical recording medium, and a push-pull signal corresponding to a difference between the amounts of light in the two areas is produced. The level of the push-pull signal is compared with a reference level, to discriminate the type of the optical recording medium.

The semiconductor laser driving device is provided with a semiconductor laser for emitting laser beams, and a temperature detecting means for detecting a temperature of the semiconductor laser, and changes an output of the laser beams based on the detected temperature. Thus, the semiconductor laser driving means can suitably improve response characteristics of the semiconductor laser, irrespective of the temperature of the semiconductor laser.
