17.3 Storing and Handling Test Discs
●
Surface precision is vital for DVD test discs. Be sure to store and handle them carefully.
1. Do not place discs directly onto the workbench, etc., after use.
2. Handle discs carefully in order to maintain their flatness. Place them into their case after use and
store them vertically. Store discs in a cool place where they are not exposed to direct sunlight or
air from air conditioners.
3. Accurate adjustment will not be possible if the disc is warped when placed on a surface made of
glass, etc. If this happens, use a new test disc to make optical adjustments.
4. If adjustment is done using a warped disc, the adjustment will be incorrect and some discs will
not be playable.
