As for tape, I don't trust it long-term. I remember back in the old "analog" days we recorded data on 1-inch AMPEX instrumentation tape. We tried to play back some acoustic data after the tape was on the shelf for about 10-years and discovered that the data was corrupted by a large amplitude "screeching" noise. We figured out that the iron oxide was coming loose and collecting on the read heads. This made the heads "sticky" which caused the tape to vibrate as it passed the heads. This vibration was the screeching noise. Lots of data lost.
Mag tapes need rewinding every now and again to prevent 'print-through', long before they age enough for the oxide to fall off. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
