One format that has always puzzled me was the early Brush Soundmirrors that
used a half track positioned in the middle of the tape.
Can't speak for this, but I recall in my Brush recorder, the erase was a
magnet which swung into place when a recording was being made. Quite primitive,
whot?

The Utah "Magictape" did the same thing. The machine was an upright and took
B-wind tape, and it ran through a trough with the heads coming down when
engaged. I never saw a pressure pad till we bought the first Wollensak in '59.
(And then we went through a process of copying all the old tapes, which was a
mistake, but when you're 14 it's hard to argue with a paterfamilias who sees
slow speeds and half track as an opportunity to re-use all the old paper tapes
and get 4 times as much use out of them....then came quarter-track....)
