I think I might have a whack at making R/W heads using
small ferrite
cores/beads, the kind used in radio work.
...lots of detail...
So, aside from the mumbles, does this sound like a
workable plan?
I'd think that you'd want the head characteristics to be a very close
match if you intend to employ more than one head per track--and I
can't see how you'd get the head gaps remotely close in
characteristics with one another.
On the local Freecycle, I see VHS recorders hitting the landfill with
incredible regularity. Why not simply scavenge the heads from a few
of these? Certainly, the frequency response should be good enough.
As far as the disk goes, that should work. It seems to me that some
of the Shugard SA-4000 models even had a track or two of fixed heads
as an option.
Cheers,
Chuck
