The ECMA stuff is very physical and does not apply much to drive control and burn programming. This is rather documented in the SCSI standards. The CD/DVD/BD specific aspects are in sub section MMC. I use as reference http://www.t10.org/ftp/t10/drafts/mmc5/mmc5r03c.pdf see especially the description of multi-session media models: 4.3.4 DVD-R/-RW 4.3.6 DVD+R There are newer documents in http://www.t10.org/ftp/t10/drafts/mmc6 My own view on MMC is documented in http://libburnia-project.org/browser/libburn/trunk/doc/cookbook.txt You might be interested in - Sequential DVD-R[W] Cookbook - DVD+R[/DL] Cookbook Another thing is emulated multi-session on overwriteable DVD/BD media: growisofs and xorriso learn about the current session size from the ISO superblock (ECMA-119 8.4 Primary Volume Descriptor), add a new session and patch the superblock so that it points to the new session.
