Another vote for Ari and Paul. If you want to store digital files, go
with RAID storage. Kodak has an interesting approach using "analog
devices"!!!
I might find the reference for you, if one of our colleagues does not
come up with it earlier.

I would like to second Ari's point as well.
There is almost no reason to use optical media for storage anymore.
Go with the live RAID storage. If you cannot afford that, you can buy
several external HDs for pennies a GB. The important point is to keep
your data live.
If you are storing your
Susan, Yes, media can fail anytime so it is always a good idea to have two
copies (preferably on two types of media.) Lifespan beyond 10 years is
pointless anyway because you will most likely want to take advantage of
bigger and speedier and cheaper storage devices. Don't sweat it, keep
moving.
HI Susan, Ari, et al,
This may be a little out of date (2004), I seem to remember this
issue being raised before:

Technology

There is _no_ assured lifetime for optical media (DVD, CD). There are claims
that "archival quality" media last for 100 years. There is also experiential
evidence that this is not so. Optical media may fail catastrophically at any
time (although the odds are that a given platter will last for many

The lifespan of polycarbonate discs, with silver/silver alloy data

A couple of conservation questions:
Our laboratory director came to me last week. He is starting to digitize
his old maps on DVDs.
He ran across some information that said that the lifetime of DVDs is only 5
years. Is that true?
If so, what is the estimated lifespan of the gold plated DVDs?
