3-2 Storing and Handling DVD Discs
Surface precision is vital for DVD 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 from being 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.
