DVD+R DL RW... is this a rewriteable DL?

Just recently purchased my first DL disks, and noticed that they have RW on the face… Im sure the bloke in the shop mumbled something about them being rewriteable as they were + format…

I didnt think there was such a disk available…???

RW is a generic logo which confuses many people. It does not mean that the actual media itself is rewritable.
