IMPORTANT

THIS PIONEER APPARATUS CONTAINS

LASER OF CLASS 1.

SERVICING OPERATION OF THE APPARATUS

SHOULD BE DONE BY A SPECIALLY

INSTRUTED PERSON.

LASER DIODE CHARACTERISTICS

MAXIMUM OUTPUT POWER: 32 mw

WAVELENGTH: 785 nm

Laser pickup assy

The output power at the objective lens of this assy is 0.73 mW.

Control method of the current through a laser diode.

The resistor R105 on the MD CORE MAIN UNIT (For 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 the 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 level) 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
