Re: The Digital Fad "AAvK" <Idondodat@wahoo.com> wrote The information isn't in the gold, the gold is just there as a mirror. In the early days the plastic backing on the CD's wasn't too good and folks who lived by the sea had the salt-fog eat away the aluminum in the CD's: hence the gold. Miami is real big on gold plated door hinges, bathroom taps etc, but it isn't for the looks. The information is in an organic dye that has been painted onto the gold and then burned with a laser. Think food coloring. [This is a gross oversimplification, but it gets to the gist of it.] There is no argument that binary data can be preserved for close to forever. The unanswered questions are: o Can you find a CD player in the year 2306? How about DVDs, Blu-Ray, Quad-DVD and the 20-30 new formats that will be at one time or another _The Standard_ over the next few centuries? o Will anybody bother sorting through 300 year's worth of old CD's, playing them back, just to see what is on them? If you really want to keep images the best bet may be technologies like cyanotype on papyrus and Pt/Pd. -- Nicholas O.
