<p>A laser reproduction apparatus for reproducing the data recorded in a recording medium such as an optical disc or a photomagnetic disc by irradiation with a laser beam, wherein a current value of a drive signal of a laser diode (12) is set to be close to a value at which the condition of irradiation with the laser beam is least affected by the return light, the irradiation with the laser beam from the laser diode (12) according to the current value thus set is effected intermittently at predetermined intervals, and a single period of the irradiation does not allow writing into the recording medium (11) at the set current value. Therefore, the laser beam is affected little by the light reflected by the recording medium (11), resulting in good data reproduction. Furthermore, the circuit for driving the laser diode (12) is simplified.</p> |
