Evert and All,
Some interesting comments on this thread, thanks to all. But a CD-R that
lasts only ten years??!! Shock horror!! The Verbatim "DataLifePlus" CD-R
discs that I use (when I can get them) claim "100 years archival life". I
was hoping for perhaps 50 years, if stored in good conditions. Are Verbatim
and other CD-R manufacturers' claims for their products, patently untrue?

OK I'll try writing on the see-thru part in the middle, from now on. All I
need to write is a code number, very small, and I'm using a waterproof
superfine permanent marker (presumably it is oil-based as it has an alcohol
base). I'll keep doing that until I'm convinced I must not.
