Media care

This section provides tips on protecting data stored on your CDs, DVDs
and BDs. Handle your media with care. Following the simple precautions
listed below will increase the lifetime of your media and protect the data
stored on it.
1. Store your CD/DVD/BDs in the containers they originally came in to
protect them and keep them clean.
2. Do not bend the CD/DVD/BDs.
3. Do not write on, apply a sticker to, or otherwise mar the surface of the
CD/DVD/BD that contains the data.
4. Hold the CD/DVD/BD by its outside edge or the edge on the center hole
- any fingerprints on the surface of the disc can prevent the drive from
properly reading data.
5. Do not expose the CD/DVD/BD to direct sunlight, extreme heat or cold.
6. Do not place heavy objects on your CD/DVD/BDs.
7. If your CD/DVD/BDs become dusty or dirty, wipe them with a clean dry
cloth from the center hole outwards - do not wipe in a circular direction.
If necessary, you can use a cloth that has been lightly dampened in
water or a neutral cleaner but you must not use benzine, thinner or any
similar cleaning solution.
