Coming in on this a little bit late, but if you haven't checked out the
Library of Congress you should.
www.loc.gov/preserv gives you a basic run down of ways to care for archived
materials, and the NIST/CLIR puts out Special Publication 500-252 "Care and
Handling of CDs and DVDs - A Guide for Librarians and Archivists" (e-version
available). Other tips- gold disks, AZO dye are reputed to last longer.
The phenomenon of failure from the outside in has interesting possibilities-
have software write a known pattern in the outermost section of the disc and
pop up a warning when it starts to deteriorate. Hopefully this would give
enough time to move data to another disk.
