■
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 or DVD-RW/+RW is affected
by the quality of the disc and the way it is used.
■
There are two types of DVD-R: authoring and general use discs. Do not
use authoring discs. Only general use discs can be written to by a
computer drive.
■
Other DVD-ROM drives for computers or other DVD players may not be
able to read DVD-R/+R/-RW/+RW discs.
■
Data written to a CD-R/DVD-R/+R disc cannot be deleted either in whole
or in part.
■
Data deleted (erased) from a CD-RW and DVD-RW/+RW disc cannot be
recovered. Check the content of the disc carefully before you delete it. If
multiple drives that can write data to discs are connected, be careful not
to delete data from the wrong drive.
■
In writing to a DVD-R/+R/-RW/+RW disc, some disc space is required for
file management, so you may not be able to write the full capacity of the
disc.
■
Since the disc is based on the DVD-R/-RW standard, it will be filled with
dummy data if the written data is less than about 1 GB. Even if you write
only a small amount of data, it might take time to fill in the dummy data.
■
Two types of DVD-R/+R/-RW/+RW discs are on the market: data and
video. Use a video disc to store video data. You can use video discs on
a DVD recorder as well as on your computer's DVD-ROM drive. You
cannot use data discs on a DVD recorder..
■
When multiple drives that can write data to discs are connected, be
careful not to write to the wrong drive.
■
Be sure to connect the universal AC adaptor before you write or rewrite.
