NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic
breakdown because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair , pay attention to electrostatic breakdown and also use
the procedure in the printed matter which is included in the repair
parts.
The flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical pickup block.
Therefore, when checking the laser diode emission, observe from
more than 30cm away from the objective lens.
Before Replacing the Optical pick-up Block
Please be sure to check thoroughly the parameters as per the “Optical
pick-up Block Checking Procedure” (Part No. : 9-960-027-11) issued
separately before replacing the optical Pick-up block.
Note and specifications required to check are given below.
• FOK output : IC501 !™ pin
When checking FOK, remove the lead wire to disc motor.
• S curve P-to-P value : 0.9 – 1.5Vp-p IC501 #¡ pin. (Connect pin
!™ of IC501 (TP880) and 3 of IC501 (GND) with a jumper
wire).
When checking S curve P-to-P value, remove the lead wire to
disc motor.
• Adjusted part for focus gain adjustment : R V503
• RF signal P-to-P value : 0.85 – 1.15Vp-p

Precautions for Checking Emission of Laser Diode
Laser light of the equipment is focused by the object lens in the
optical pick-up so that the light focuses on the reflection surface of
the disc.
Therefore, be sure to keep your eyes more then 30cm apart from
the object lens when you check the emission of laser diode.
Laser Diode Checking Methods
During normal operation of the equipment, emission of the laser
diode is prohibited unless the upper panel is closed while turning
ON the S801 (push switch type).
The following two checking methods for the laser diode are operable.
Method-1 (In the service mode or normal operation) :
Emission of the laser diode is visually checked.
1. Open the upper lid.
2. Push the S801 as shown in Fig. 1 .
3. Check the object lens for confirming normal emission of the
laser diode. If not emitting, there is a trouble in the automatic
power control circuit or the optical pick-up. During normal
operation, the laser diode is turned ON about 2.5 seconds for
focus searching.

Focus/Tracking Gain Adjustment
V
V
V
A servo analyzer is necessary in order to perform this adjustment
exactly.
However, this gain has a margin, so even if it is slightly off,
there is no problem. Therefore, do not perform this adjustment.
Focus/tracking gain determines the pick-up follow-up relative to
mechanical noise and mechanical shock when the 2-axis device
operate. However, as these reciprocate, the adjustment is at the point
where both are satisfied.
• When gain is raised, the noise when 2-axis device operates increases.
• When gain is lowered, it is more susceptible to mechanical shock
and skipping occurs more easily.
This adjustment has to be performed upon replacing any of the following parts :
• Optical pick-up
• RV503 (Focus gain)
• RV502 (Tracking gain)
Normally, be sure not to move RV503 (focus gain) and RV502
(tracking gain).
– Focus Gain Adjustment –
Procedure :
This adjustment is not performed. If focus gain RV503 is turned,
set to mechanical center.
– Tracking Gain Adjustment –
(perform at normal operation)
1. Place the optical pick-up level, horizontally. (If the optical pickup is not level, the 2-axis device will be weighted and adjustment
cannot be done.)
2. Connect the oscilloscope between IC501 0 pin (TEO) and #º
pin (VC) on the MAIN board.
3. Set the disc (YEDS-18) and Press the ^ (+) key.
4. Turn R V502 slightly clockwise (tracking gain drops) and obtain
a waveform with a fundamental wave (waveform has large
waves) as in Fig. 1 .
5. Turn R V502 slowly counterclockwise (tracking gain rises) until
the fundamental wave disappears (no large waves) as in Fig. 2.
6. Set RV502 to the position about 30°counterclockwise from the
position obtained in step 5. If RV502 contact point is more than
90° counterclockwise from mechanical center, tracking gain is
too high. In this case, readjust from step 4.
7. Press ^ (+) or = keys and observe the 100 track jump
waveform. Check that no traverse waveform appears for both
^ (+) or = directions. (See Fig. 3 and 4.) It is acceptable
if the traverse waveform appears only now and then, but if it
appears constantly raise tracking gain slightly and check step 7
again.
8. Check that there is no abnormal amount of operation noise (white
noise) from the 2-axis device. If there is, tracking gain is too
high, readjust starting with step 4.
The waveforms are those measured with the oscilloscope set as
shown below .
• VOLT/DIV : 50mV
• TIME/DIV : 5mS
• Waveform when tracking gain lowered.
