Caution on optical pickup:
- The optical pickup and the magnetic head are structured precisely; therefore, they are very fragile. Be careful not to touch
them with the edge of laser power meter.
- The sensor of the laser power meter is a very fine part. Be careful not to touch it to the optical pickup lens.
- The focus point of the laser reaches to 180°C. Therefore, avoid using laser power for a long time because the sensor of
the laser power meter may be burned.
