Cautions
About handling the optical pickup and the magnetic head.
-
The optical pickup is structured precisely; therefore, it is very fragile. Be
careful not to touch it with the edge of the laser power meter. Do not touch
the lens.
-
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 356°F. Therefore, avoid adjusting
using laser power for a long time because the sensor of the laser power
meter may be burned.
-
Do not set the unit to the laser power adjustment mode with the MD loaded.
Doing so may result in damage to the MD.
