I got a lot of info on the topic simply by Googling "shelf life of CDs".
Very interesting reading. I think I'll plan on a fresh of my video and photo
DVD/CD backups every couple of years

I learned the hard way that this happens ... I tried to open some CDs
of articles I had recorded for a club magazine I was editing.  The index
came up but none of the files would.  I took the problem to a couple of
local experts and they said the CDs were too old to open.  Everything
was lost.  At that time I was told that pc burners worked differently than
the way commercial CD makers record things.  There may have been 
some further explanation but by then they were speaking 'computer-eez.'

Apparently there is no way to predict when the items will be lost and the
only way to save things is to 're-burn' the information onto a new CD 
before that happens.  A DVD is something different so I do not know if
there is a problem with them or not.  I have noticed there is some degree
of reverence reserved for those that can say D-V-D the fastest :-)

Pictures printed on paper can be preserved for untold lengths of time by
putting them in a album where thay are out of the light.

>Hi Ken, How do you determine the "shelf life" and what can be done 
>to extend it? Does this also apply to
   DVD's? I have a CD of  pictures from the NECC Beaverun race days, 
Iowa Mini Covnention and the DACC
from last year. The NECC was a professional photographer but the 
others were provided by personal friends.
