Disc-at-Once (DAO)

This method is used to write all data onto a disc in one operation. It writes

multiple pieces of data without placing a space between data, starting with the

innermost track of the disc. Once data is written by this method, no data can be

added to the same disc even if there is free space available on the disc. This

method is useful for making a backup copy of an entire disc.

Track-at-Once (TAO)

This method is used to write data on a disc on a track-by-track basis. A track can

be defined as the smallest unit of area that contains an ordinary program, image

file, text file, etc. This method enables you to add data to the same disc, one

track of data at a time, as long as there is free space available on the disc. A disc

that contains data written in several sessions is defined as a multi-session disc.

An area that records data and management information (Lead-in/Lead-out) is

defined as a session. Lead-in and Lead-out are signals written for stating the

starting and ending points of one session.

Ordinary audio CD players can only play back single-session discs or the first

session on a multi-session disc. Do not record audio data on the second and

subsequent sessions.

Session-at-Once (SAO)

This method is used to write data on a disc on a session-by-session basis. Unlike

Track-at-Once described above, Session-at-Once enables you to record multiple

tracks onto a disc at a time. CD EXTRA, for example, uses this method to write

multiple pieces of audio data (or multiple tracks) in the first session and

information required for computers in the second session. This method enables

you to add data into the same disc, one session at a time, as long as there is free

space available on the disc. A disc that contains data written in several sessions

by this method is defined as a multi-session disc, like a disc written by the

Track-at-Once method.
