Once again I enter your kingdom with my head bowed low. I am about to ask a question and some of you will wonder how another human being cannot know such basic stuff.
I am burning some MP3 CDâs for a friend, but Nero is asking me if I would like to make a multi-session disk.
After some research on the internet as to what a multi-session disk might be, it struck me that I am lost once again lost in the world of technology. So, my questions:
I am using CD-Recordable disks (not re-recordable). So, can I even make a multi-session disk in the first place?
If I didnât make a multi-session disk (if I could), what would I be missing out on? I get the point about a multi-session disk being able to add stuff later, but I donât think I will need to anyway. So, anything else I need to know?
Say you have a 700 MB CDr, if you burn a document thatâs 2 MB, without using multi session function, then you have waisted 698 MB of disc space.
But if you use the multi session function once you burn your 2MB doc. then later if you want to burn another doc of say 5 MB on that disc, you can, coz you have more session available. Savy?
No, donât do that (donât make a multi session) ⌠just fill up the CD and burn it in one time and see that itâs finalized (closed) ⌠if you donât do that another CD/computer can not read the disc.
A multi-session disk is one that you keep adding to until it is full. Itâs doesnât mean you can write over existing data. By closing a CD (i.e. not making a multi-session disk) another CD player or computer can read the data. By keeping the disk âopenâ it means that some players might struggle to work out what the heck is going on.
Well, based on the info I think I will be finalizing my disks (please note my confident use of technical jargon) for this particular project.

Eurika! I think I get itâŚ:yay:

You got it.
Note though that there are some CD-R that do not support multi-sessions, usually those have a slightly higher capacity and are meant for audio/hifi use (i.e. copies of audio CDs).

Yes, you got it. Learn something new every day, eh?
You know them audio CDs with a CD-ROM part, often containing videos ? The audio part is one session, the cd-rom part is another session. Audio CD players only see the first session and ignore the second session so it doesnât confuse them.
Please allow me to enjoy my recent cognitive breakthrough for at least one more day. Whatever it is that doesnât confuse the audio CD player you were talking about will surely confuse me.
Actually even a multisession disc closes the session you burn. It does this by writing the usuall Leadin and Leadout of the disc and between that your data but adding an additional Leadin after the already closed 1st session. This allowes adding data in the future. On some drives and players this can cause problems, espacially if their firmeware is not 100% compatible to the different standards (Redbook, Bluebook, etc.). The newer drives and players usually have no problems with that, besides some Car HIFI and some DVD players.
A single session disc closes (finalizes) the disc and the unused storage is lost.
Another point is, that with every session you add, you lose the space which is needed for the Leadin and Leadout which together 2min 30sec of playtime of the disc per session. (The MB you lose depants on what mode you use, Mode1, Mode2, etc. but you can roughtly say 1 min is 10 MB).
Discs with 2 sessions on it where the first one is Audio and the second is ROM (Data) are called CD-Extra. This were created to have a normal Audio CD which causes no problems on Audio players but also has some stuff like videos and multimedia on a 2nd part which computer dirves can read (as the use ROM drives). This discs can cause problems on DVD players as some of them use ROM (Data) drives, so the software of some players were confused. This disc type was usually comercially created and sold and not so much used from home users, so most of this disc will be original CDâs (replicated ones, not burned).
The last type was the Audio combinded discs. They had the first track data and than some Audio tracks. This discs were used before CD-Extra. Most of them for computer games. The first track was the data (the game) and than followed by some Audio tracks which where the music and sound for the games. If you put that Discs into a Audioplayer, some might play the ROM part which sounds like a terrible brawling. The later players usually could read out that the track was ROM and simply muted that track. To avoid this problems the CD-Extra was invented and used.

Just if you go and open a proper Belgium restaurant again with some decent food.
