Using Dragon Burn, you can create four types of CD-R discs: Audio CD, Data CD (CD-ROM), Mixed-Mode CD and CD Extra.
A CD-ROM disc contains data only. For example, when you back up all the data files from your hard disk to CD, the disc that will be created is a CD-ROM disc. When creating a Data CD, you can also choose the file format for the completed CD. This can be the standard Macintosh file format (HFS), the ISO9660 file format (used by Windows-based computers), or even a combination of the two formats on the same CD.
An Audio CD disc contains only digital audio information. The sources of digital audio are Audio CD (music or songs) on a disc in a CD-ROM drive, Wave, mp3 and AIFF files on your hard disk.
A Mixed Mode disc contains both data and digital audio. Data is recorded on the first track, while audio is on tracks 2 to 99 of the same disc.
CD Extra, also known as CD Plus or Enhanced CD, includes two sessions with the first session containing up to 98 audio tracks and the second session containing a data track written in the CD-ROM XA format.
