Media care
This section provides tips on protecting data stored on your CDs, DVDs 
and Blu-ray™ discs. 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/Blu-ray™ discs in the containers they originally 
came in to protect them and keep them clean.
2. Do not bend the CD/DVD/Blu-ray™ discs.
3. Do not write on, apply a sticker to, or otherwise mar the surface of the 
CD/DVD/Blu-ray Disc™ that contains the data.
4. Hold the CD/DVD/Blu-ray Disc™ 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/Blu-ray Disc™ to direct sunlight, extreme 
heat or cold.
6. Do not place heavy objects on your CD/DVD/Blu-ray™ discs.
7. If your CD/DVD/Blu-ray™ discs 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.
