With a sharp enough v-notch and very gradual abrasion from the
outside, is should be possible to make the gap less than one thou.
This is sort of the inverse of the way they made the point contacts
for the first transistor at Bell Labs.

So, aside from
the mumbles, does this sound like a workable plan?
Ah no. the gaps have to be narrow less than .001". that hs been done
two peice ferrite heads (half beads) with oe side of the magnetic
circuit
filled with .001" thick brass shim stock.
Or you could pull the heads from a number of old floppies.
The 14" platter is a good source for media.
