| 英文摘要 | PURPOSE:To control always the oscillation output stably by providing two stabilizing control loops and operating one stabilizing control loop in the reproducing mode and operating the other in the recording mode. CONSTITUTION:An output (h) of a current supply circuit I is 3' in case of T= 25 deg.C and is 5' in case of T=50 deg.C in the first control loop using a sample and holds circuit 15, and stabilizing control is so performed that the light emission output of a semiconductor laser due to the control loop is 1' stably in the reproducing mode as well as the recording mode. An output (i) of a current supply circuit II is 4' in case of T=25 deg.C and is 6' in case of T=50 deg.C in the second control loop using a level detecting circuit 20, and stabilizing control is performed so that the amplitude of the variation due to a data signal of the light emission output of the semiconductor laser due to the second control loop is 2' stably in the recording mode. Thus, the first stabilizing control loop is operated in the reproducing mode and the second stabilizing control loop is operated in the recording mode to control always the oscillation output stably. |
