1. The ON/OFF(ON:low level,OFF:high level) status of the
CLAMP signals for detcting the loading state are detected
by the drive CPUs, and the design prevents laser diode
oscillation when the CLAMP signal turns OFF.
In normal operation, if no disc is clamped, the laser diode
oscillation is disabled.
However, the interlock does not always operate in the test
mode.
*
2. When the cover is opened, close viewing of the objective
lens with the naked eye will cause exposure to a Class 3A
laser beam.
Additional Laser Caution
* Refer to page 50.
