Preventing Premature Disc Failure

Preventing Premature Disc Failure

The NUMBER ONE cause of premature disc failure with recordable CDs is contamination of the recording surface before recording is completed. To minimize disc failure, use the following disc-handling guidelines:

•Keep the disc tray and disc as clean and dust-free as humanly possible during the record process. DO NOT touch the recording surface, and do not expose the disc tray and disc to dust or dirt.

•DO NOT BLOW ON THE DISC to remove dust or dirt. To remove dust from the recording surface use a camera lens bulb. Be sure to follow the instructions when using the cloth.

•To remove stubborn dirt or grease from the recording surface use only nonabrasive foam-tipped swabs (such as Chemtronics Foamtips #120) with a small amount of pure, denatured alcohol. To avoid scratching the recording surface BE SURE TO USE ONLY LIGHT STROKES, beginning at the disc center, pulling directly towards the disc’s outer edge.

•Always record in a dust-free environment. If the disc must be removed from CRW4416SX before recording is finished, store the disc in a clean, dust-free environment.

•If a disc tray accumulates dust, DO NOT USE IT FOR DISC RECORDING. Always use a clean, dust-free tray for disc recording.

If CRW4416SX is vibrated while recording, the recording may fail. To avoid such failures observe the following practices:

•Place CRW4416SX on a solid, stable surface, away from high- traffic areas. The surface must allow CRW4416SX to operate in a level, horizontal position.

•Avoid touching or handling CRW4416SX when recording.

Note: Once the disc has been finalized (and no more recording is possi- ble), it can be handled with the same care that any CD should be handled.
