Whats a stacking ring?
(2005/04/24) The term is used to describe a slight ridge near the hub of standard CD-R media. This provides a small amount of separation between discs stacked on a spindle. You can tell if your discs have stacking rings by piling them up and then pressing down on the outside edge. If the stack compresses slightly, they have the ring; if they’re solid, they don’t. The ring is helpful when feeding discs into automated recorders because it keeps the discs from sticking to each other. It can interfere with hub labels or with printing near the disc hub, so you can often order the same media with or without the ring. There may be some benefit to using discs with the ring even if you’re just burning the occasional disc and using standard labels. The ridge is on the bottom of the disc, which means if you put the disc down on a table, most of the bottom surface won’t be in direct contact. This could help avoid scratches.
