Doesn't CD-Rs use organic materials unlike BDs?

I think the parent commenter is making a funny. CD-Rs were often unreadable within a few years even under ideal conditions. Put one out on your desk where sun from a window can reach it and you might not be able to read the disc in a few months.

Putting a label on a CD-R kills them extra fast.
