Thank you very much! I google for imgburn on linux, i find it, http://forum.imgburn.com/index.php?showtopic=2045 i would try, I would prefer a can real-time and delete and modification burn a CD-r open source software, don't know you have you already seen? The meaning is CD-r of the file system is udf, like hard disk use, the site has instructions, http://en.wikipedia.org/wiki/Universal_Disk_Format "
Normally, authoring software will master a UDF file system in a batch process and write it to optical media in a single pass. But when packet writing to rewriteable media, such as CD-RW, UDF allows files to be created, deleted and changed on-disc just as a general-purpose filesystem would on removable media like floppy disks and flash drives. This is also possible on write-once media, such as CD-R, but in that case the space occupied by the deleted files cannot be reclaimed (and instead becomes inaccessible).
Multi-session mastering is also possible in UDF, though some implementations may be unable to read disks with multiple sessions"
