Optical Media Dos

Here is a list of dos for you to follow to maximize the longevity of any optical media you may be using.

1. 1. Handle discs by the outer edge or the center hole.
   2. Use a non-solvent-based felt-tip permanent marker to mark the label side of the disc. Over time, some marking inks may penetrate the disk and reach the reflective layer.
   3. Keep dirt or other foreign matter from the disc.
   4. Store discs upright (book style) in plastic cases specified for CDs and DVDs.
   5. Return discs to storage cases immediately after use.
   6. Leave discs in their packaging (or cases) to minimize the effects of environmental changes.
   7. Open a recordable disc package only when you are ready to record data on that disc.
   8. Store discs in a cool, dry, dark environment in which the air is clean.
   9. 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. The reason for this is that any scratches that are made will be such that it will have a minimal impact on the ability to have its data read.
   10. Use CD/DVD-cleaning detergent, isopropyl alcohol, or methanol to remove stubborn dirt or material.
   11. Check the disc surface before recording.
   12. For long-term storage store at temperatures between 39°F to 68°F with relative humidity from 20% to 50%.
