Quick Reference Guide for Care and Handling
- Handle discs by the outer edge or the center hole.

- Keep dirt or other foreign matter from the disc.
- Store discs upright (book style) in plastic cases specified for CDs and DVDs.
- Return discs to storage cases immediately after use.
- Leave discs in their packaging (or cases) to minimize the effects of environmental changes.
- Open a recordable disc package only when you are ready to record data on that disc.
- Store in a cool, dry, dark environment in which the air is clean.
- Remove dirt, foreign material, fingerprints, smudges, and liquids by wiping with a clean cotton fabric in a straight line from the center of the disc toward the outer edge.

- Expose discs to extreme heat or high humidity.
- Expose discs to extreme rapid temperature or humidity changes.
- Expose recordable discs to prolonged sunlight or other sources of UV light.
