IPC: G11B7/125
Filed: 2001-06-07
Abstract: PROBLEM TO BE SOLVED: To provide a laser driving circuit that performs blocking error-free and address error-free high-accuracy recording and reproduction without shortening the operating life of a high-intensity semiconductor laser which performs high-speed recording on an optical disk nor discharging unnecessary radiation. SOLUTION: The driving current is supplied to a laser diode 1 to cause the diode 1 to emit laser light of a prescribed intensity from an automatic output control circuit 5 in accordance with the intensity of the light emitted from the diode 1 detected by means of a photodiode 2, and is modulated by superimposing a high-frequency signal having a frequency of 50-800 MHz from a high-frequency oscillation circuit 6 and a signal having a frequency of 10-50 MHz from an oscillation circuit 7 upon the current. Consequently, the coherence of the laser light is lowered by multimode oscillation over a wide frequency band, and the occurrence of mode hopping noise is significantly suppressed with an expanded margin. In addition, the occurrence of external feedback noise can be prevented.  Therefore, the blocking error-free and address error-free high-speed recording can be executed with high accuracy without shortening the operating life of the laser diode 1 nor discharging unnecessary radiation.
