Lessee, yes you can re-record on used wire. In fact if you didn't erase
it you would get a overdub! Oh, the wire is soft iron, though any wire
of a magnetic alloy can be used. The technology date t before WWII to
some time in the late 40s-early 50s. It's problems were poor frequency
response, knots/kinks in the wire and head wear.
