Well, A third way of doing it is:
cat /dev/cdrom > mycd.iso cp, cat, dd, it doesn't really matter. The UNIX abstraction of everything to a file (series of bytes) makes things more flexible. The only difference I see is the fact that dd allows you to specify the block size while dding (I believe it defaults to 512 bytes), thuse playing around with the copying speed or if you had other intentions (its too detailed to go thru for this thread). Now, I assume cp would be copying 4K blocks at a time (due to the fact that it originally assumes a filesystem underneath?).
