Title: Laser diode drive circuit
Inventor: OBARA KAZUAKI
IPC: G11B7/125
Filed: 1988-11-25
Abstract: PURPOSE:To prevent discontinuation of the light emission of a laser diode when the power of the diode is switched from reproducing power to signal recording power by stopping flowing of a high-frequency current when reproducing power is switched to signal recording power and making a DC to flow to the laser diode together with another DC. CONSTITUTION:At the time of recording signals, the current of a DC source 102 is made to flow to a laser diode 106 together with the current of another DC source 101 by closing a switch 109 by means of a control signal 112. Simultaneously, flowing of a high-frequency current from a high-frequency current source 104 to the diode 106 is stopped by opening a switch 111 by means of a recording/reproduction switching control signal 112. By adding the DC to the laser diode 106 a current larger than the threshold current value (Ith2) can be made to flow to the diode 106 when the high-frequency current is not superposed. Therefore, discontinuation of the light emission of the laser diode 106 can be prevented.
