ABSTRACT:
An apparatus and a method for recording and reproducing an information signal onto an optical recording medium are disclosed. The apparatus includes a laser light source for radiating a laser beam onto the optical recording medium, a laser driver for driving the laser light source and a device for moving the medium relative to the laser beam. The laser driver controls the laser light source to selectively perform continuous light emission or intermittent light emission with a sufficiently higher frequency than that of the information signal during reproducing. By adopting the light intermittent emission of the light source, the formation of pits with some errors can be prevented and the reliability of the recording and reproduction can be enhanced.
