2.4.
Static Electricity Protection Measures
• The laser diode in the traverse unit (optical pick-up) may break down due to potential difference caused by static electricity of
clothes or human body.
So, be careful of electrostatic breakdown during repair of the traverse unit (optical pick-up).
2.5.
Ground for electrostatic breakdown prevention
• As for parts that use optical pick-up (laser diode), the optical pick-up is destroyed by the static electricity of the working environ-
ment.
Repair in the working environment that is grounded.
2.5.1.
Work table grounding
• Put a conductive material (sheet) or steel sheet on the area where the traverse unit (optical pick-up) is placed, and ground the
sheet.
2.5.2.
Human body grounding
• Use the anti-static wrist strap to discharge the static electricity from your body.
2.5.3.
When exchange the Drive
• Before remove the ESD prevention bag, make sure to use the anti-static wrist strap to discharge the static electricity when
replace the Drive.
Note:
The ESD prevention bag is used to replace the original short-circuit point.
It can be removed while placing the Drive.
