I would believe that with both of these devices it is possible to be read and write directly.
I use the sdd program to directly write tar backups to DVD+RW medium daily on multiple servers. The process does require a special 2.4.x kernel to be built with a patch. I would not know about 2.6.x kernel support. I think the DVD writer also requires "raw" device support. The sdd progam is required to create an output block size of 32k if I recall from the write up. The command would be something to the following if the dvd writer was bound to raw1: sdd if=/dev/tape of=/dev/raw/raw1 obs=32k This process will not produce an ISO-9660 image on the DVD+RW. So it will not be mountable. But it will provide the sequential access structure that the original medium contained. The produced copy can be read back or restored just like the original medium using tar, cpio, etc. like the original tape. Since the capacity of the tape may be slightly less than that of the DVD+RW medium, the structure size and block counts could probably be ignored. An error would result at the end of the tape and terminate the transfer. I would consider this the fastest and most efficient process to transfer the data to the new medium.
