I sent Joel a personal reply to his message originally posted in the
archives list. This is a condensed version. Please forgive any cross postings.
I don't know anything about the MediDisc but I can talk about gold discs.
I'll go ahead and give the disclaimer. I'm biased. I sell the product. I'm
not biased because I sell it. I sell it because I'm biased and believe it's
a top notch solution.
Discs can fail for 5 main reasons. 1) Oxidation of the reflective surface.
2) Dye failure. 3) Bonding failure, which can cause the layers to
delaminate. 4) Scratches on the surface. and 5) Production quality
variations. Please see my website in the signature below for additional
data. See the Archival DVD's and CD's link at the top. The bottom line is
that you need protection from all 5 of these problems if you want to be
sure that your data will last as long as possible.
My personal opinion, based on my research, is that if I had a valuable
archive to protect and preserve, I would use only the discs described on my
website. I would tell you that whether I sold them or not. In fact, I do
have a valuable archive to protect, my own collection of 200 personal video
tapes. These are the discs I'm going to use to transfer them to DVD.
You can check out the manufacturer's website at:
You have to poke around the site a bit to find the right links. Here are
some you might find interesting.
That should get you started. 8-)
