disc at once (CD) (DAO)

Disk at Once(DAO) is a writing method for CD recorders in which the compact disc (CD) is burned in one pass; all tracks one after the other. The writing process starts at the lead-in, writes the data, and concludes with the lead-out. With Disk at Once (DAO), no link is burned between each session. DAO is particularly interesting for making music CDs.
