Writable DVDs and compatibility
The drive can write to DVD+R DL, DVD+R and DVD-R discs, as well as to
DVD+RW and DVD-RW discs, when used with writing software. The
playback (read) compatibility of data written by this drive depends on the
capabilities of the DVD-ROM drives or the DVD players and on the logical
format selected when the disc is recorded (written).
DVD+R DL/DVD+R/DVD-R Discs
Data can be written to this type of disc only once. Once it has been written, it
cannot be erased. Playback (read) compatibility of DVD+R and DVD-R discs
depends on the capability of the DVD-ROM drive and the DVD player and on
the logical format selected when it is recorded (written).
DVD+RW and DVD-RW Discs
Data can be repeatedly written to or erased from this type of disc. Typically, a
new DVD+RW or DVD-RW disc can be rewritten about 1,000 times.
Playback (read) compatibility of DVD+RW and DVD-RW discs depends on
the capability of the DVD-ROM drive and the DVD player and on the logical
format selected when it is recorded (written).
About playback/reading compatibility in DVDs
DVD+R DL/DVD+R/DVD-R discs, as well as DVD+RW and DVD-RW
discs created and finalized with the drive can be played back on almost all
DVD-ROM drives. However depending on the type of your drive, playback of
DVD+R DL, DVD+RW, and DVD-RW discs may not be supported.
In addition, some drives do not support multi-session (DVD+R DL/DVD+R/
DVD+RW) or multi-border (DVD-R/DVD-RW). In these cases, you can only
play back the disc in single-session (DVD+R DL/DVD+R/DVD+RW) or
single-border (DVD-R/DVD-RW).
Also, DVD-Video discs created with the drive can be played back on many
standard DVD players. However depending on the type of your player,
playback of DVD+RW and DVD-RW discs may not be supported.
Further, because of the differences in quality and characteristics between
various DVD-ROM drive, DVD player, DVD+R DL disc, DVD+R disc,
DVD+RW disc, DVD-R disc, and DVD-RW disc manufacturers, playback
may not be possible depending on the combination. (Playback compatibility is
not under warranty.)
