Comment Audio Tapes (Score 1) 498
I have reel-to-reel audio tapes from the 60s that still play on my tape deck from the 70s. I have digital backups, but I don't know if they will last the same 40-50 years that most of the original analog tapes have. My most recent "recovery" was a transfer to digital form about four years ago.
Some of the tapes have degraded and are not recoverable as the layer from one winding of tape has stuck to the adjacent winding.
