Cd/dvd

[gau_pppu]

what is the diff between burning cd/dvd in "disc at once mode" and "track at once mode" is it some thing related to making multisession dosc?

"Disc at once mode" removes blank gap between the audio tracks. So the playback of the burned CD will be continuous play. On the other hand, "Track at once mode" brings in blank gap between the audio tracks. This is achieved by stopping the laser beam intermittently to include blank gap between songs.

Hence the difference can be seen only when you burn Audio files. For a Data CD, the gap makes no difference.
