My batch seem to be a mixture of short ends of both RicohJPNR02 and RitekR03 batches with about 15 Ricoh and 35 Ritek. Although some people seem to dislike Ricoh discs, I've had excellent luck with them. I don't think the "regular" price w/ shipping on these discs is very good considering that I got a mixed batch of shorts. You could probably do better with a true batch of Ridata in the cakebox.
