Let do it! Seems like the process is possible from what I can tell.
I think the ferrite is straight forward cutting and lapping, but I was surprised the surface around it is alumina. Need to see if there is a way to cut that precisely in a home lab.
General all base tech in a dark gap between late 70s and mid 90s. At the time the net became real, companies no longer cared for making paper data sheets for older stuff, while people still not cared to preserve old tech. A dark age looking back :))
Reminds me when I learned about acoustic piezoelectric delay lines for PAL TV decoding. "Excuse me the fucking WHAT now". You heard me. Old nerds fucking rock: https://en.wikipedia.org/wiki/Delay-line_memory
Oopsie. Just found out the white part of the disk head is ceramic or very brittle. Tried grabbing the head with pliers to loosen it from the glue and it shattered into 100,000 shards.
Here you will find a lot of videos and deep technical informations, mainly about 2'' quadruplex video heads, but probably valuable for other kind of magnetic heads: https://quadtapetransfer.com/video-head-rebuilding
This guy is refurbishing video head for an Akai VT-100 VTR by replacing broken ferrites with U-Matic ones, rewinding new coils on them, glue them back on holders, and putting back the heads on the drum. Impressive! https://www.youtube.com/watch?v=mNnnCT1am-M
Impressive, even if VT is a low quality format.

Go away!
BTW - Glass gap heads are the gap between the ferrite pole pieces fused with glass for mechanical stability.

I need to go buy a "the heads don't work" 1541 so I can do science on that one.
on the plus side, now it can permanently engrave data onto the disk for playback on a record player.
VCR flying heads will be so much easier than tunneling erase heads.
... I can smell that picture.
