Various Topics on Scanners

.... .. ..d..mach..

I've been making backup copies of my film scans on CD-R for years. I
keep them in individual paper sleeves which I buy from a local CD
manufacturing outfit. The kind often used for commercial software, white
paper, transparent circular window on the front side, and a
self-adhesive flap at the top. Always liked this neat solution with the
CDs stored in cardboard boxes so one can easily flip through them.

Now, I'm discovering that after a few years the part of the CD that's
been next to the self-adhesive flap at the top of the sleeve shows a
distinct brownish colouring. Obviously something has evaporated from the
adhesive and penetrated the top-coating of the CD because I can't wipe
it off.

Some, but fortunately not all of the CDs have become unreadable in this
area.

Just thought I'd give out a warning, in case someone else has had the
same idea...

If just never fancy the idea of gummed stuff near anything important
so if I have any paper sleeves like that I either give them away or
use them for sending through mail. Have you tried the ones which are
clear plastic on the front and a kind of soft stuff at the back? A
little like the inserts in CD pouches, no adhesive etc and reasonably
priced usually. I think they are cl***ed as cloth lined safety
sleeves. prices vary depending on manufacturers etc.

Wrong OS, I'm afraid. Thanks anyway. :-)

Hi.

Sensible warning to all, but the fault is not so much in the sleeves, it is
the leaving them for a few years. Your archives should be rotated onto new
media fairly often, probably no later than 1 or 2 years.

Ralf, are you saying the gummed flap was tucked in so that the gum was
directly touching the CD, or was the gummed flap outside the envelope and
not touching the CD?

The latter. No direct contact to the CD.

That is pretty spooky. I was hoping the other way

Thanks for your sympathy, Wayne. As if having a long holiday weekend
completely ruined by rain wasn't bad enough.
