[cctalk] Aging of unused CD-R media

I find myself wondering, how well does CD-R and DVD-R media that hasn’t been used age? I have quite a bit of unused Verbatim DataLifePlus, as well as some other media that’s unused. For the most part, I don’t need it, but I can see a couple reasons I might want to burn some in the future, mainly to exchange data with older systems. Zane
