• Do not place objects on the disc tray.
• Never use a damaged, broken, scratched, or deformed disc.
• Keep the disc tray closed when the drive is not in use.
NOTE: High-speed drives spin the disc at a high rotational speed. If a disc has
printing on only half of the disc, or if there is a slight imbalance in the disc, the
imbalance is greatly magnied by the high speed, causing the drive to vibrate or
produce a fan-like noise. These effects are inherent in the high-speed technology
and do not indicate a problem with the drive.
