You can do Track-at-once (TAO) or Disc-at-once (DAO), it won't matter as far as the text is concerned, I don't think.
TAO writes one song (track) to the disc, shuts off the laser, writes the next track, shuts off the laser, etc. This puts a 2-second gap between each track.
DAO writes all the tracks wthout shutting off the laser between tracks. This makes the gap between tracks whatever you defined it as.
