Handling discs, Storing discs, Discs to avoid

Before You Start

The process of finalization fixes the contents of a CD–Rin place for good by creating a Table of Contents (TOC, for short) at the beginning of the disc which tells other players exactly what's on the disc and where to find it. Once a CD–Ris finalized, further recording and other changes become impossible. The CD recorder and other CD players treat a finalized disc as an ordinary playback-only CD. (See page 33 for more information on finalizing CD-recordable discs.)

CD-rewritable discs can be finalized in the same way as CD–Rdiscs, but even after finalization, the disc can still be erased and used over again. Remember that CD–RWdiscs can only be played on players that are specifically designed to play CD–RWdiscs: most home CD players will not play these discs, even after the disc has been finalized. (See page 33 for more information on finalizing CD-rewritable discs.)

Getting Set Up

Handling discs

When holding CDs of any type, take care not to leave fingerprints, dirt or scratches on the disc surface. Hold the disc by its edge or by the center hole and edge. Damaged or dirty discs can affect playback and/or recording perfor- mance. Take care also not to scratch the label side of the disc. Although not as fragile as the recording side, scratches can still result in a disc becoming unusable.

Should a disc become marked with fingerprints, dust, etc., clean using a soft, dry cloth, wiping the disc lightly from the center to the outside edge as shown in the diagram below. If necessary, use a cloth soaked in alcohol, or a commercially available CD cleaning kit to clean a disc more thoroughly. Never use benzine, thinner or other cleaning agents, including products designed for cleaning vinyl records.

Storing discs

Although CD, CD–Rand CD–RWdiscs are more durable than vinyl records, you should still take care to handle and store discs correctly. When you're not using a disc, return it to its case and store upright. Avoid leaving discs in excessively cold, humid, or hot environments (including under direct sunlight).

When labeling discs, use a felt-tip pen sold for marking CDs. Don't glue paper or put stickers onto the disc, or use a pencil, ball-point pen or other sharp-tipped writing instrument. These could all damage the disc.

For more detailed care information see the instructions that come with discs.

Discs to avoid

CDs spin at high speed inside the player during playback and recording. If you can see that a disc is cracked, chipped, warped, or otherwise damaged, don't risk using it in your CD recorder or player—you could end up damaging the unit.
