I'm a bit surprised that there don't seem to be any adaptations that
hook into the head pre-amps and use an ADC to give a view of what the
read signal actually looks like. Maybe that's asking too much--there
are certainly MCUs with sufficiently fast ADCs and memory to do this.
I suspect that would be too drive-specific for most users.
Yes the head preamp outputs are nearly always available on testpoints
on the drive PCB (you use them when doing a head alignment) but having
to find them and connect to them could be non-trivial.
At least with the flux transition interfaces all you have to do is
plug into the normal drive ribbon cable connector.
