Media Care
This section provides tips on protecting data stored on your CD/DVD/BD.
Handle your media with care. The following simple precautions will
increase the lifetime of your media and protect the data stored on them.
CD/DVD/BD
1. Store your CD/DVD/BD in the container they came in to protect them
and keep them clean.
2. Do not bend the CD/DVD/BD.
3. Do not write on, apply a sticker to, or otherwise mark the surface of the
CD/DVD that contains data.
4. Hold the CD/DVD/BD by its outside edge or the edge on the center
hole. Fingerprints on the surface can prevent the drive from properly
reading data.
5. Do not expose to direct sunlight, extreme heat or cold.
6. Do not place heavy objects on your CD/DVD/BD.
7. If your CD/DVD/BD become dusty or dirty, wipe them with a clean dry
cloth. Wipe from the center out, do not wipe in a circular direction
around the CD/DVD/BD. If necessary, use a cloth dampened in water or
a neutral cleaner. Do not use benzine, thinner or similar cleaner.
