Sorry, I thought you were posting on a local list.

I thought the older ones were obsolete. They used disks that wrote magneticly
(laser heated the media and made it magneticly changeable) but were read
opticaly. Still exist in SOny audio minidisks. relativly low capacity, high
price, but very relible.

If you are going to archive to DVD make sure to verify the data after writing,
and make multiple copies. CDs are better than DVDs as they don't get damaged
as easily, but are obviously lower capacity.
