■ If the disc is poor in quality, dirty or damaged, writing or rewriting errors
may occur. Be careful to check the disc for dirt or damage before you
use it.
■ The actual number of rewrites to CD-RW, DVD-RW, DVD+RW or
DVD-RAM is affected by the quality of the disc and the way it is used.
■ There are two types of DVD-R discs: authoring and general use discs.
Do not use authoring discs. Only general use discs can be written to by
a computer drive.
■ You can use DVD-RAM discs that can be removed from a cartridge and
DVD-RAM discs designed without a cartridge.
■ Other DVD-ROM drives for computers or other DVD players may not be
able to read DVD-R/-RW or DVD+R/+RW discs.
■ Data written to a CD-R/DVD-R/DVD+R disc cannot be deleted either in
whole or in part.
