What Is an MP3 Disc?

An MP3 disc is a CD or DVD that contains audio files in the MP3 file format and is playable by MP3 disc players, computers, and some DVD players. You should only use MP3 files to build an MP3 disc.

MP3 files are compressed and take up far less space than audio tracks on an audio CD, which tend to be approximately ten times larger than an equivalent MP3. Although this high compression somewhat limits the quality and audio range of an MP3 file compared to an audio CD track, the difference is hardly noticeable.

Why Should You Choose an MP3 Disc Over an Audio CD?

Choose the MP3 disc format in any of these conditions:

•	You want to put a large amount of audio on one disc--approximately ten times the amount of audio that a regular audio CD can hold

•	You want your audio files to be as small as possible

•	You want to group your tracks in folders for organization (for example, a folder for each album on the disc)

Supported File Formats

An MP3 disc can only contain MP3 files. Use iTunes® to encode your audio in MP3 format.
