From what I can make out your trying to say, the answer is yes. You can make several different recordings at different times, you can even delete recordings (this does not actually delete the recording, it just stops the player from recognising it, and makes it skip forward automatically) once deleted you simply lose the space on the disc. Once you finalise the disc, and enable it to be played in other players no changes can be made.
Hope this helps,
Sorry if it doesn`t
