Audio CDs
Many legacy hardware devices (such as car stereos) still require Audio CDs. A common problem with user-written discs is that the wrong burn type is selected when creating the cd, causing the legacy hardware to reject the disc. DAO (Disc at Once) is the correct burn setting when creating an audio cd. This "closes" the disc to any further writing and causes the disc to behave as any commercially bought audio cd. The opposite of DAO is SAO (Session at Once) which allows further writing to the disc in any unused space, but is generally incompatible with CD Audio players.
- Some audio cd hardware was designed as "burnt cd friendly", meaning that it understood unclosed discs. These are fairly uncommon.
