CD-R/RW disc handling and cleaning

Disc handling

●Do not place a disc in direct sunlight for an extended period of time.
●Hold a disc by inserting a finger in the center hole and pressing your thumb against
the outer edge. Be careful not to get fingerprints on, or scratch the recording surface
of the disc (the green surface).

●Do not drop or stack discs.
●Do not place heavy objects on a disc, or subject it to strong physical shock.
●Do not affix stickers to the label surface of the disc. If a disc is used with a sticker
affixed, read/write errors can occur, or the disc may be scratched.
●When writing a title on the label surface of the disc, use a soft-tipped
writing implement such as a felt pen.
●To protect the disc, keep it in its original case.

Disc cleaning

●If dust or dirt adheres to a disc, gently wipe it off with a soft dry cloth. Always wipe
from the center of the disc outward toward the outer edge. Never wipe the disc in
the direction of rotation.
