LASER DIODE CHARACTERISTICS
MAXIMUM OUTPUT POWER: 23 mW
WAVELENGTH: 778 – 787 nm
1. Laser Interlock Mechanism
The position of the switch (S601) on the SERVO
MECHANISM Assy for detecting loading state is detected
by the system microprocessor, and the design prevents
laser diode oscillation when the switch (S601) is not on
CLMP terminal side (CLMP signal is OFF or high level.).
Thus, the interlock will no longer function if the switch
(S601) is deliberately set to CLMP terminal side (low
level).
The interlock also does not function in the test mode
∗
.
Laser diode oscillation will continue, if pin 1 of M51593FP
(IC101) on the PRE-AMP BOARD ASSY mounted on the
CD-R PICKUP is connected to GND, or pin 19 is
connected to low level (ON), or else the terminals of Q101
are shorted to each other (fault condition).
2. When the cover is opened with the servo mechanism
block removed and turned over, close viewing of the
objective lens with the naked eye will cause exposure to a
Class 1 laser beam.
