and that has the effect of making the system approximately displacement based rather than velocity based.

Right, until you get to the top end and then rate limiting hits you again.
You can draw a profile curve of frequency vs amplitude and see how you are
hit by displacement limitations in one direction, rate in another direction,
and (with all but the fanciest Neumann cutters) heating in a third. Sort of
a safe operating area curve for audio.


If a cutter would work at half the speed, wouldn't that fix these
problems? Never mind that no playback cartridge could play it...


I said precisely that earlier in this thread.
I don't have the pulleys and the EQ module for half-speed mastering, but
they exist, and folks have used them.


My bad, I missed it earlier.
