CD-Rs - I have a lot of old burned backup discs of different brands. They were stored in various ways (spindles, CD binders, loose in a plastic box...), age between 15-25 years old. I went through them a year or two ago. The one brand of disc that
every disc was still perfectly readable was Verbatim.
I've also heard that JVC (Taiyo-Yudens) have similar reliability but I haven't any from then.
I remember plenty of coasters (failed burns) from cheaper budget brands. I put one in a microwave to see what would happen. Made the kitchen smell bad for a while (nice light show though).
