]. Laser Interlock
Mechanism
The ON/OFF
(ON : low level, OFF : high level) status
of
S601
(LPS1)
and
S602
(LPS2)
switches
for
detecting the loading state is detected
by the system
microprocessor,
and
the
design
prevents
laser
diode
oscillation except when both switches S601
and S602
are ON (low level or clamped
state).
Thus, interlock will no longer function if switches S601
(LPS1) and S602 (LPS2) are deliberately shorted (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 pickup assembly 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).
. 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
vRW-328
to a Class 1 laser beam.
