Additional Laser Caution
1. The ON/OFF(ON:low level,OFF:high level) status of the
CLAMP signals for detecting 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
"LD Degration Judgment of ATA/ATAPI DEBUG OSD" and
"LD POWER ADJUSTMENT"*.
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.
* Refer to Pages 49 and 79.
