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.
