Using the Right Recording Media
All DVDs and CDs look similar, but different types have different capabilities. Using the correct recording media is necessary
to the success of your recording project.
The table below indicates the appropriate media types for each kind of disc-recording project supported by your DVD-RW
drive.

Your DVD-RW drive can use four different blank recording media types:
 DVD-R for General
DVD-R for General (DVD Recordable media for General use) is DVD media that you can write to, but which cannot be
erased. With your DVD-RW drive, you can write information to a DVD-R for General disc only once. DVD-R for General
media is appropriate for both video and data DVD projects. (Do not confuse DVD-R for General discs with DVD-R for
Authoring, which is a special media for commercial DVD production and which requires special equipment.)
 DVD-RW
DVD-RW (DVD Rewritable media) is DVD media that you can write to, erase, and write to again. With DVD-RW media,
you can record information to the same disc again and again, although you must erase existing information from the
disc before each recording session. DVD-RW media is appropriate for both video and data DVD projects.
 CD-R
CD-R (CD Recordable media) is CD media that you can write to, but which cannot be erased. Depending upon the
software you use and how the disc was formatted, you may be able to add additional information to a CD-R disc
that already has data on it. CD-R media is appropriate for music and data CD projects.
 CD-RW
CD-RW (CD Rewritable media) is CD media that you can write to, erase, and write to again. Depending upon the
software you use and how the disc was formatted, you may be able to add additional information to a CD-RW disc
that already has data on it. CD-RW media is appropriate for music and data CD projects.
There are a variety of CD and DVD media types that you cannot write to with your DVD-RW drive (although, depending
upon how a particular disc was recorded, your DVD-RW drive may be able to read some of these media types). Media types
your DVD-RW drive cannot write to include:
 CD-ROM
 DVD-R for Authoring
 DVD-RAM
 DVD+R
 DVD+RW
Even with the proper type of media, the quality of manufacture and compatibility with different equipment varies from
manufacturer to manufacturer and even from disc to disc from the same manufacturer. If you are confident you are using
the proper type of disc for your project and you are having trouble recording information or playing a disc, try a different
disc or a different brand of disc.
