Buying blank CDs and DVDs
You can order blank CDs using iTunes.
To buy blank discs:
Choose Help > Shop for iTunes Products.
To make audio CDs that work in most stereo systems, use CD-R discs. CD-RW discs usually work only in computers.
To make a CD of MP3 files to play in your computer or an MP3 CD player, use a CD-R disc; some MP3 players can play CD-RW discs as well.
If your computer has a DVD burner, you can back up your files to a DVD-R or DVD-RW disc. DVDs you create using iTunes work only in your computer (not DVD players).
