ABSTRACT:
A magnetooptical information recording-reproducing apparatus is adapted to function for any card-like optical recording media having different properties. A light beam is applied to a predetermined location of the recording medium and a reflected light caused upon the application of the light beam is detected so as to detect the property of the recording medium such as a reflectance. The gains of a signal reproducing system, a tracking control system and a focusing control system are controlled to vary according to the detection result concerning the property of the recording medium so that a reproduction signal, a tracking error signal and a focusing error signal assume predetermined levels, respectively.
