Subject: RE: TECH: How long do CDRs last?
Interesting quote, John. My experience has been that I get great results with Maxell and Verbatim, and everything else I've tried is complete trash. Maybe that's why.

DAT tape is magnetic, so it has a shelf life of about 20 years, max.

L.G., for archiving photos, the best method is still processing on high quality paper, storing in a dry, dark place when not viewing, and never, never covering them with plastic or leaving them next to paper with acid in them. Photo albums with "magnetic" pages are just about the worst thing you can do for photos.

The paper & processing matters a lot. Older b&w/sephia photos have a lifespan of 200+ years, and genuine b&w processing is still the longest life. Color processing is getting better, but early color photos are already severely degraded.

Our family has some very old photos, going back to the Civil War era. A few years ago I did an archival-quality album AND scanned everything, burned them on CDs, and distributed them to lots of family members. The album cost a small fortune to make, but it was worth it. It seemed the safest way to preserve them for another 4 or 5 generations.

Color laser prints also have a very long lifespan. No one knows for sure, but the estimate is 100+ years.
