摘要: A method for reproducing signals in an optically recording medium of the type which pits are erased or embossed by temperature rise caused through projecting a light beam reading out signals, reflection factors changed beam. The variation substantial size region because change is prevented. For this prevention, example, sensor (20) sensing magnetooptical disc (11) provided. By controlling laser power and external magnetic field according to sensed (20), kept constant always.
