Title: Optical recording and reproducing device
Inventor: SASAKI YOSHIHIRO
IPC: G11B7/125
Filed: 1991-06-28
Abstract: PURPOSE:To prevent an excessive drive of a laser oscillator right after the changeover from reproducing to recording. CONSTITUTION:A laser diode 11 is driven by a driving circuit 8 during a recording mode. The amount of light generated by the diode 11 is detected by a photodiode 12 whose detection signal MONI is supplied to a controlling circuit 7. The controlling circuit 7 controls controlling voltage SV2, which is given to the driving circuit 8, based on the detected signal so as to keep the amount of light generated by the diode 11 constant. Under a normal condition, a switch SW3 is turned off and a switch SW4 is turned on and a capacitor C1 is operated to cut the high frequency components of the detected signals so that the stable control voltage SV2 is supplied to the driving circuit 8. Right after the changeover from a reproducing mode to a recording mode, the switch SW3 is turned on, the switch SW4 is turned off for a certain duration so that the capacitor C1 does not operate. By this, the response characteristics of the circuit 7 become better and an excessive current flow in the diode 11 is prevented right after the changeover to a recording mode.

IPC: H05B41/16
Filed: 1987-06-25
Abstract: PURPOSE:To make a final life term of a discharge lamp exactly detectable with simple circuit composition by providing a circuit in which a change in a voltage level at a connection point of a capacitor and a diode is used to discriminate a full-wave discharge state from a half-wave discharge state in the discharge lamp. CONSTITUTION:A series circuit of a capacitor C3 and a diode D3 is formed so as to have a relation parallel to a discharge lamp DL1. A circuit, in which a change in e voltage level et a connection point of the capacitor C3 and the diode D3 is used to discriminate a full-wave discharge state from a half-wave discharge state in the discharge lamp DL1, is formed. Namely, a voltage Vc3 across the capacitor C3 on the full-wave discharge state is made different from that on the half-wave discharge state, and so the full-wave discharge state in the discharge lamp DL1 can be discriminated from the half-wave discharge state in it by the use of the change in the voltage level at the connection point of the capacitor C3 and the diode D3. Accordingly, discrimination of the half- wave discharge state enables the detection of a final term of the discharge lamp.
