Operating Basics
n DVD Super Multi Double Layer drive cannot use discs that allow writing
faster than 16x speed (DVD-R and DVD+R media), 8x speed (DVD-R
(Dual Layer), DVD+RW and DVD+R (Double Layer) media), 6x speed
(DVD-RW media), 5x speed (DVD-RAM media).
n Some types and formats of DVD-R (Dual Layer) and DVD+R (Double
Layer) discs may be unreadable.
n 2.6 GB and 5.2 GB DVD-RAM media cannot be read from or written to.
n DISC created in DVD-R (Dual Layer) format4 (Layer Jump Recording)
cannot be read.
n If the disc is poor in quality, or is dirty or damaged, writing or rewriting errors
may be noted - ensure that you check all discs for dirt or damage before you
use them.
n The actual number of rewrites to CD-RW, DVD-RW, DVD+RW or DVD-RAM
media will be affected by the quality of the disc itself and the way in which it is
used.
n There are two types of DVD-R media available, authoring discs and general
use discs. Do not attempt to use authoring discs as only general use discs can
be written to by a computer drive.
n You can use both DVD-RAM discs that can be removed from a cartridge and
DVD-RAM discs designed without a cartridge.
n You may find that other computer DVD-ROM drives or other DVD players may
not be able to read DVD-R, DVD-R (Dual Layer), DVD-RW, DVD+R, DVD+R
(Double Layer) or DVD+RW discs.
n Data written to a CD-R, DVD-R, DVD-R (Dual Layer), DVD+R or DVD+R
(Double Layer) discs cannot be deleted either in whole or in part.
n Data deleted/erased from a CD-RW, DVD-RW, DVD+RW or DVD-RAM disc
cannot be recovered. You must check the content of the disc carefully before
you delete it, taking care that, if multiple drives that can write data to discs are
connected, you do not delete data from the wrong one.
n In writing to DVD-R, DVD-R (Dual Layer), DVD-RW, DVD+R, DVD+R (Double
Layer), DVD+RW or DVD-RAM media, some space is required for file
management, so you may not be able to write to the full capacity of the disc.
n Since the disc is based on the DVD standard, it might be filled with
dummy data if the written data is less than about 1 GB. Therefore, in these
circumstance, even if you write only a small amount of data, it might take
additional time to fill in the dummy data.
n When multiple drives that can write data to discs are connected, be sure that
you do not write to or delete data from the wrong drive.
