ABSTRACT:
A semiconductor laser control apparatus is used for controlling a semiconductor laser as a light source in an optical pick-up device for optically reading information on an information recording medium. The semiconductor laser control apparatus carries out emission or absorption of heat with respect to a semiconductor laser emitting a laser beam by a temperature control element arranged adjacently to the semiconductor laser on the basis of a current delivered from the power supply.
