Any advice on which archival CDs and DVDs are good; that is, really
archival?

Thanks,
Mike.


None. All have limited life and must be re-archived after a period of
years, which varies with the quality of the media and storage
conditions.

Ah yes, we are, after all, finite beings -- but I would
guess that some are substantially better than others. It
is the names of those better ones I seek.

Cranberry claims their DiamonDisc system makes DVDs that will last
1000 years. Instead of storing the data on a dye layer, they use
synthetic stone and etch deeper pits with a higher powered laser.
Write-once, I would imagine. I haven't tried them.

I've also read of one long-term data storage currently in the
theoretical stage. They described a system of carbon nanotubes each
holding an iron particle which would have a theoretical life of a
billion years. I'm sure it would be great for thumb drives, and since
it's the position of the iron in the tube that stores the data it
would probably be easier to securely erase than magnetic systems. But
a 1000-year system would probably be sufficient for most people.


I just perused the NAWC China Lake report, the Millentia disk kick butt
big time. They ran a very aggressive accelerated life cycle test and
only the Millentia's passed.

Misubishi and Verbatim were absolute failures.

Delkin and MAM-A failed, but at least there was probably a lot of
readable data on the disks.

25 disks ea, Mitsubishi, Verbatim 0% survival.
Delkin 45% survival
Millentia: 100% survival.

I'm trying to get pricing from Millenntia. Just wished they did this in
BluRay. A DVD doesn't hold very much and I suspect this technology
doesn't lend itself to dual layer...
