I just had an idea (that someone else has probably already had, for sure) for a media that should last close to forever. Make the CD out of glass instead of plastic. Since you can't exactly "stamp" glass with the CD master, you could probably use ultrasonics to "etch" the pits into the glass. Apply a good coat of gold over that, then some kind of protective layer, and you've got something that should last a long long time. Yes, it is fragile (depending on the type of glass you use, i suppose) and expensive, but in cases where you require very long life, that would probably be an option. -- Chris Dillon - cdillon@wolves.k12.mo.us - cdillon@inter-linc.net /* FreeBSD: The fastest and most stable server OS on the planet.
