You can burn a data CD or DVD with any of the songs and spoken word content in your iTunes library. You might want to do this to make a backup copy (or archive) of all your audio files, or to transfer them to another computer.
To burn a DVD, your computer should have an internal SuperDrive and Mac OS 10.2.4 or later. Some third-party DVD burners may also work. You can store about 650 MB of files on a CD, and about 4.7 GB on a DVD.
Any audio files in the playlist (MP3, AAC, AIFF, WAV, Audible) are copied to the CD or DVD.
Tip: You can only burn a CD or DVD from the songs in a playlist. If the playlist contains more songs than will fit on a single disc, iTunes will notify you and will give you the option to use multiple discs. You can see the size of the selected playlist at the bottom of the iTunes window.
