I think it was

Then why was is it that DD media bought well
after HD media was available, in use, and the norm still had the reinforced ring?
Tradition?
You might be putting it in an old drive. It was also available without, I had several
thousand without reinforcements from Verbatim, bought in bulk bags.
My recollection
is that media tagged for RX50 use (the stuff with the
arrow stickers) never had the reinforcing rings, as they were probably
not needed.
