8.7.1. Precautions in optical pickup
replacement
The optical pickup can be damaged by static electricity
from you body. Be sure to take static electricity
countermeasures when working around the optical pickup.
(Refer to the related page in this Manual about the
countermeasures.)
1. Do not touch laser diode, actuator and their peripheries.
2. Do not use tester to check laser diode. (Laser diode can be
damaged easily.)
8.8. Disassembling the Middle
Chassis
1. Remove the holder pins.
2. Remove the tab.
3. It lifts while pulling it in the direction of the arrow.
8.9. Disassemblingthe Traverse
Gear A
1. Remove the traverse gear A.
3. The use of soldering iron with anti-static feature is
recommended when providing short-circuit to laser diode or
when removing it.
4. Solder the land on flexible cable of optical pickup unit.
Caution
"
""
" ·"
""
" When using the soldering iron without anti-static
feature, short-circuit the flexible cable terminal with a
clip before short-circuiting the land.

"After intended repair is finished, remove the solder
for short-circuit of laser diode in a correct way
following the procedures described in this Manual.
8.10. Disassembling the Spindle
Motor Unit
1. Remove the floating rubbers.
