magnetized steel wire as the recording medium.
I had no idea that was how recordings were (or at least could) be made at the time. Of course it makes sense-- early use of magnetic tape was something like nickel coated bronze, so there's no reason a wire couldn't also work.
Just a bit of electronics history I wasn't aware of that I thought interesting.

- quintushoratius 5y agoI think part of the reason for using wire was for fire proofing. The recording would be salvageable even after intense fires. Later recorders used plastic tape but also have a water vessel. As the water boils it keeps the interior from going above 100C - until it boils away. The recorders are rated for maybe 30-60 minutes of direct exposure. Recent recorders use solid state storage and, still, water to keep the internal temperature lower.
