@luka excellent ! it also take care of some margin for the cd thickness as I see :)

too bad that format is really going to die ... (I'm afraid to try my "old" work >10y cd-R archives .... :z )
it seems that even the commercial ones don't keep over time and that this technology is apparently a hickup in the History... :D
