LASER DIODE CHARACTERISTICS MAXIMUM OUTPUT POWER: 32 mW WAVELENGTH: 785 nm Control method of the current through a laser diode. The resistor R105 on the CORE MAIN UNIT ASSY (For

8、 MD mechanism assy) are for the limiting of current through a laser diode. Control method of the laser output power The laser pickup assy provide the photo-diodes and APC (Auto Power Control) circuit. The photo-diode detect output of the laser diode then IC104 control the APC circuit according to th

9、e signal voltage of the photo-diode via IC101. The Variable resistancer on the FPC in the Laser pickup assy can be adjusted the output level of Laser diode to fix the rated output level. Laser Interlock Switch The loading position detect switch S101 is set to “ LOAD ON ” (ON: low level, OFF: high le

10、vel) position, IC104 get the “ LOAD ” signal, and hand the laser “ LDON ” signal to No. 9 terminal (LDON) of the Laser pickup assy. Then a laser diode can be lighted exept when the level of signal “LOAD ” is low. Additional Laser Caution 1. SAFETY INFORMATION This service manual is intended for qual

11、ified service technicians; it is not meant for the casual do-it-yourselfer. Qualified technicians have the necessary test equipment and tools, and have been trained to properly and safely repair complex products such as those covered by this manual. Improperly performed repairs can adversely affect

12、the safety and reliability of the product and may void the warranty.
