Okay, after reading the whole thread again and going through some websites and the Nero manual..I still don't get it. Sorry guys. :o
I think I know what tracks and sessions are, sort of. DAO writes all tracks in 1 go, TAO turns off the laser with each track..okay. But what happens with data discs with only one track? What is the difference THEN?
Here's what Nero does:
1) when selecting TAO: burn track -> burn lead-in/lead-out (at this point the drive first spins fast for a while, then slow for a while..so I think it burns something at the start AND end of the disc)
2) when selecting DAO: burn lead-in -> burn track -> burn lead-out
Does DAO turn off the laser between the leads and the track? I spent a dozen of discs (of 30MB) trying to figure it out.. It seems TAO does, but I'm not sure about DAO.
Is there a difference in the sequence of leads, track, session openings/closures...you know in this case of a one-track data disc?
Btw, 1) doesn't seem to fit in your diagram debro?
Sorry for the long-winded discussion, but I'd really like to understand.
