Uh-oh! Old CDs breaking down - Check your archives.

(in article ): I recently pulled out commercial open-reel tapes that were at least 35 years old. All but one were in perfect or close-to-perfect condition. (Amazingly, I'd bought a second copy of that recording some years back, so I had a good spare.) I will eventually dub them to 8mm DAT -- unless I can find a "reasonably" priced four-channel recording system for my computer. (8mm DAT is not exactly robust.) ------------------------------snip------------------------------ I wouldn't do that if I were you, Bill. DAT is really flakey; I did some archival restoration a few years ago, and we wound up using 6 different DAT machines (including two $7000 Sony PCM-7040's) to play back tapes made from 1990-1998. DAT is a very, very impermanent medium. BTW, DAT is only 3.8mm, not 8mm. I would trust something like this more to digital files. A reasonable A/D converter is well under $500 these days; dub it to high-res WAV files, then make several backups. I try to operate on Peter Krogh's 3-2-1 Backup Rule: http://www.dpbestflow.org/backup/backup-overview Interestingly, the studios are using LTO-4 and LTO-5 data tapes for most of their backups these days. But I've seen cases where the older DTF and DTF2 backup tapes failed, causing much consternation and disaster. --MFW |
