AW: Echolette, Binson EchoRec

I remember this book - the idea of gluing a tape to a disc or drum
was that you could use standard tape heads, but they would not have
to touch the tape - there would be a tiny gap. No tape wear.
I wonder how good the bearings for such a rotating disc have to
be, in order to have a constant gap. Hard to imagine that it could work
at all, for a "mechano-phobe" like me, but that doesn't mean anything.

I also remember someone who suggested to use an old (vinyl) record
player for this.

How is it done in that famous Binson Echorec ? How thin is the gap
between head and the magnetic surface ?

Anybody experimented with writing analogue signals to a Floppy disc ??

(just brainstorming)
