Thank you! That is a great write-up!
In the early 1990s I worked for a CD foundry. We mostly made CD backups of nuclear plant records, and short runs of off-brand music. The resist dye got EVERYWHERE, because humans spill things; red blotches on everyone's work shoes.
If those "3 year" predictions meant anything, half of our business would have gone for tape backups.... Don't know if it's accurate, of course.
