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
LABEL CHECK ( for MJ-L5/MYXK and NVXK only )
