I bought a pack of 25 of these sometime in March for their regular price of 17.99. The media code was AN31. They burned fine on my NEC ND-2500A, but I prefer my other media to this stuff. Some of the discs had some minor marks on them that did end up wiping off, but the media seemed pretty cheap. I may end up buying another spindle at this price because it is so cheap just to have for data storage.
