"RW" means "rewriteable", you can erase them and record on them again. "ROM" means read-only memory (a bad use of the term memory), where the medium cannot be written to. As to the original poster's question, plus and minus media are physically different from each other. You need suitable hardware to write, and read, them. -- Don't send private replies to my address, the mailbox is ignored. I read messages from the public lists.
