Session-at-Once (SAO)
This mode is used when writing each session in a single pass without pausing. More
sessions can be added later if there is enough space left on the disc.

Example: CD-Extra
With CD-Extra, the audio is written in the first session and the data is written in the
second.
A maximum of 99 tracks can be written.
Packet Writing
This mode is used when writing to a track of a disc using small blocks of data called
“packets,” in a manner similar to a floppy disk. This mode is useful when making
small incremental backups of data. You will need to use software that specifically
supports packet writing, such as Adaptec’s DirectCD.

Packet
Same as writing to floppy or hard disk
Discs must be formatted before they can be used for packet writing. With CD-RW,
erased data can be overwritten until the disc is completely full.
With CD-R, the space used by the erased data cannot be reused and is “masked” so
that it is no longer visible. This can be done up to 100 times.
