Cautionary note: I have a (ferro)magnetic tape cast-recording of "Chicago"
that somehow got too close to a degausing agent (probably a radio speaker).
All the tape that was exposed (that part between one roller and the next,
not covered by plastic) is missing any resemblence to music. Fortunately, I
can sing, hum, or whistle my way through "Chicago" to cover the lost
music--but I somehow doubt that I could do the same with lost photo-data.
Any questions?
Best regards--LRA
