Media
NOTICE:
Always use compressed air to clean the lens in the optical drive, and
follow the instructions that come with the compressed air product. Never touch the
lens in the drive.
If you notice problems, such as skipping, with the playback quality of your
media, try cleaning the discs.
1 Hold the disc by its outer edge. You can also touch the inside edge of the
center hole.
NOTICE:
To help prevent damage to the surface, do not wipe in a circular motion
around the disc.
2 With a soft, lint-free cloth, gently wipe the bottom of the disc (the unlabeled
side) in a straight line from the center to the outer edge of the disc.
For stubborn dirt, try using water or a diluted solution of water and mild
soap. You can also purchase commercial products that clean discs and
provide some protection from dust, fingerprints, and scratches. Cleaning
products for CDs are also safe to use on DVDs.
