What is a multi-session CD?
• It allows additional data to be appended to a previously recorded Disc. (Note that some older CD reader scan reads only the first session of a multi-session disc.) A session is defined as a data section including lead-in, program data and lead-out. A CD rewriter that supports multi-session can write a disc that will have multiple sessions linked together so that any multi-session supported CD reader can access the data, whether it was written in the first session or any other subsequent session.
