ABSTRACT:
A data reproducing apparatus is disclosed which permits stabilization of the light output of a light source, thereby to permit reliable reproduction of data. When recording data on an optical disk and also when reproducing the recorded data by illuminating the optical disk by means of a laser beam from a semiconductor laser, an idling current is supplied in advance to the semiconductor laser, to such an extent that the semiconductor laser does not emit a laser beam. As a result of the preliminary supply of the idling current, the output of the semiconductor laser is stabilized.
