[ale] Cd-r life

[Richard Faulkner]

IMHO any optically recorded disk is at risk the moment it is made.  Mar
the coating on the "painted" side and you're done for.  Scuff the face
and same situation.  The OLDEST data that I have on disk of value
(archival) is from 1996 and are scans of aerial reconnaissance mission
photos from World War II (pre-D-Day "dicing" missions).  These disks
date from 1996 to 2005 and are considered "short-term" solutions.  All
are on standard CD-R and have held so far and contain hi-res scans of
imagery.  And, yes...all are slated to be re-mastered from HDD versions
to true archival DVD shortly with duplicate copies stored off-site.

I was under the impression that CD-Rs last a decade or more. Spotted a post on /. saying that recordings as late as 2008 are at risk. Anyone have links to real scientific data on this issue?
