[ale] Cd-r life

[Richard Faulkner]

...please excuse me as I'm not totally awake yet (up very late last
night playing code-monkey)...but I thought I'd clarify that my CD-R's
were all considered to be short-term solutions that had lasted far
longer than I expected.  They are stored indoors in controlled temps,
away from sunlight and babied as much as can be.  All the data is kept
in redundant HDD copies as well with a duplicate copy kept off-site.
Still, those old disks are holding-up but soon to be totally retired for
fresh remasters to good archival disks from HDD.    ---R

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?
