OT: archiving on CD/DVD

[N_Cook]

As my statement about cleaning could be taken either way this is my
pre-existing statement on my tips files
"Cleaning CDs, DVDs etc
Always clean
data/audio or video CDs in a radial sense, not circumferentially, so that
any microscratches are across and not along the data paths."

I'm a big fan of paper. I have several QRS rolls of digital
music that are almost 100 years old and they still perform
faultlessly.

Hi!

I happpen to always knock down from x52 to 40 for normal burning
(slightly larger pits) and then x32 for 3 yearlt archives.

Go more slowly than that, on the order of 4X/8X burns if you want
longevity.

I store my discs in a dark, cool and dry place on shelves in their
cases.

So far the best longevity I've seen is from paper, hard disks, CDs,
QIC80 backup tapes or even carefully stored floppies, in that order.

I was really a little astounded when I unearthed some QIC80 cartridges
and found that nearly all were readable. Only one was not, and it was
because the tape had rolled into the cartridge. It could probably have
been fixed. Of course, the QIC drive is so simple, and as long as the
rubber drive roller is good, it ought to work.

In my experience, DDS and SDLT tapes have proven to be unreliable even
after as little as three years of storage.
