Seems to me that I've seen paper tape coated with oxide before
plastic. Also, the wire recorder goes back a very long time.
All of which reminds me of some of the original lab work for the IBM
1311 drive (thanks, CHM!). Take a steel disc, oxidize it and use a
unipolar read/write head. I'm surprised no amateur has tried to make
his own version of this thing.
