Marc, I did say I was doing a lot of reading, and yes I've got to that bit - Seems that specifying a multi session disc causes the system to initiate 2 TOC areas - 1 for wot you wrote, and 1 for wot you want to do next And every time you do something other than close the disc, it records wot you did in the extra TOC it has already created - and sets up another blank TOC area for your next action.
For those further interested in CD/DVD's I've got past the bit where the dye specified in the disc information may not be correct, and am into the bit about burn-proof and note that the options you may have on your drive that the software may deign to use to deal with the PC's failure to keep up with the drive when supplying data to be written to disc may include Pausing the write and then Restarting a write process at (well near) the point it stopped Slowing down the drive spin rate to allow the PC to try to keep up when it's loading the buffer And possibly speeding up the write when the buffer is filled again and the various read/write 'codec's and error recovery (or I give up on this disc) processes Derr.. My brane urts JimB. ----- Original Message ----- From: "MARC SIMS" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Wednesday, April 13, 2005 9:07 PM Subject: Re: Number of sessions allowed on a CD-R > According to the CD recording FAQ see: > > http://www.cdrfaq.org/faq07.html#S7-6 > > You didn't account for the capacity lost to the first session after its > closed which is 23MB to make room for the next > session then 14MB for each session after that.
