Ummmmm, sorry, you're WAY off base rd. Actualy the stacking ring is is that little ridge near the hub that keeps the disks slightly apart from one another when stacked. Automated CD changers do NOT like them though. (Machines that look and function as the one pictured here)
Microboards is actualy a manufacturer of stand-alone cd duplicators, and SPECIFICLY RECOMEND Taiyo Yuden disks BECAUSE they don't have a stacking ring. Be careful of un-true information. More than likely Cindi, these ARE in fact, genuine Taiyo Yuden disks, but I generaly stay away from "re-branded," media as I stongly suspect thay are a bit more likely to be, "B graded," media.
If you're in the USA, and you'd like GENUINE Taiyo Yuden media, (good choice BTW), I'd suggest just buying them from www.rima.com I've yet to hear any complaints about them whatsoever, and I'm currently buying my TY media through them exclusively. You MIGHT find them for a penny or two less elsewhere, but rima I KNOW is an authorised seller of Genuine TY media, and they have a reputation that just can't be beat.
Here's a little more information about the stacking ring that I took from here:
Specificly this part relates to the topic best. (There's also a picture there if you'd like to follow the link) :
What is the stacking ring? It is a banded protrusion jutting out (as a ring) on the bottom or non-printing side of the disc. This permits discs to be stacked on top of one another without harming the data field. The other side (printing side) of the disc leaves a very narrow gutter in the surface of the disc. The disc cannot have ink in this gutter. To avoid that, we must void that area of all ink.
That should clarify THAT! :iagree:
