MD ADJUSTMENT
Adjustment of laser power
[Adjustment]
(1) Turns MULTI JOG, and select the
LDPWR ADJUST mode.
(2) Press MULTI JOG.
(3) Turn MULTI JOG, adjust so that reading
of the laser power meter becomes 0.92mW.
Digital volt meter
[Preparation]
(1) Connect the digital volt meter to I+3V and IOP on Extended JIG.
(2) Set the optical sensor to laser power meter.
(3) Loading of the optical sensor to the unit at test mode state.
[Note]
Do the work to (5)-(7) within 15 seconds.
Since continuation luminescence of the 7mW laser power is carried out, if it is left for a long time,
the pickup will deteriorate.
(4) Press MULTI JOG.
(5) Turn MULTI JOG, adjust so that reading
of the laser power meter becomes 7.2mW.
(6) Press MULTI JOG.
(7) Press EDIT/CLEAR/NO.

Check of laser power
Continue at 6-2(Adjustment of laser power) and do this work.
(1) Turns MULTI JOG, and select the
LDPWR CHECK mode.
(2) Press MULTI JOG.
(3) Checks that reading of laser power meter is 0.92mW.
(4) Press MULTI JOG.
(5) Checks that reading of laser power meter is 7.2 mV.
(6) Measure a laser current value (V) in digital bolt meter.
Calculate laser current value (I) and compare with the
display of the label(Id) on pickup unit. (Fig-1)
I (mA)= V / 1(ohm)
Check that the laser current value(I) is Id(mA) 10%.
Notes
The current value may be large if the pickup
has deteriorated.
(7) Press the EDIT/CLEAR/NO button after check.
(8) Press EJECT and takes out the optical sensor.
(9) Remove the digital volt meter from JIG.
