Handling Dvd And Cd Media; Cleaning Discs - Plextor PX-850A Installation And User Manual

Section 4. Using Your PX-850
NOTE: Always use the eject button to close the tray in a smooth and
secure manner. Closing the tray by pressing the front of the drawer using
your hand is not recommended and risks damage or premature wearing
of the mechanism.

Handling DVD and CD Media

Take care when handling blank CD and DVD media. Dust, scratches,
and fingerprints on either side of the disc can cause write errors during
recording. When picking up or holding blank media you can either place
your fingers along the outer edge of the disc, or place one finger through
the center hole and one finger on the outer edge. Once you have finished
creating a disc, label it by writing on the top using permanent ink.
CAUTION: We recommend using a "non-toxic" marker, such as a
Sharpie® pen, that conforms to the ASTM D-4236 standard. Some
permanent markers will damage the media. Also, do not press too hard
when writing on the disc.
NOTE: We do not recommend placing self-sticking CD-R labels on the
disc. The weight of the label may unbalance the disc and cause write
errors during recording or read errors during reading. Also, attempting to
remove the label may permanently damage the disc.

Cleaning Discs

For proper read and write performance, your discs must be clean. Trying
to record on a dirty disc may result in a failed session and ruin the disc.
To clean the disc, wipe the disc using a clean, soft cotton cloth to
remove surface dirt such as fingerprints. Use a straight-line motion,
wiping from the center out. Do not wipe the disc in a circular motion.
