2 Handling Precautions for Traverse Deck

TOP PREVIOUS NEXT

The laser diode in the traverse deck (optical pickup) 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 deck (optical pickup).

2.1 Handling of traverse deck (optical pickup)

2.2 Grounding for electrostatic breakdown prevention

2.2.1 Human body grounding

2.2.2 Work table grounding

2.1 Handling of traverse deck (optical pickup)

TOP PREVIOUS NEXT

1. Do not subject the traverse deck (optical pickup) to static electricity as it is extremely sensitive

to electrical shock.

2. To protect the laser diode against electrostatic breakdown, short the flexible board (FFC

board) with a clip or similar object. Refer to Fig. 2-1.

3. Take care not to apply excessive stress to the flexible board (FFC board).

4. Do not turn the variable resistor (laser power adjustment). It has already been adjusted. Refer

to Fig. 2-1.
