The Universal Disk Format (UDF) File System. In practice, it has been most widely used for DVDs and newer optical disc formats, supplanting ISO 9660. Universal Disk Format (UDF) is a profile of the specification known as ISO/IEC 13346 and ECMA-167 and is an open vendor-neutral file system for computer data storage for a broad range of media.
Otherwise, you can just use the ISO 9660 system format if you are plainly recording data for back-up purposes, and not for audio and video playback. If you want to play your audio or video recordings, then it is best to opt for UDF. Overall, UDF is really the most compatible format for most CD and DVD players.
