Laser diode characteristics
Wave length : 785 nm to 814 nm
Maximum output : 1 190 µW(Emitting period : unlimited)
Additional Laser Caution
Transistors Q101 in PCB drive the laser diodes.
When Q101 is shorted between their terminals, the laser diodes will radiate beam.
If the top cover is removed with no disc loaded while such short-circuit is continued,
the naked eyes may be exposed to the laser beam.
