I am confused but fascinated...

Are we trying to play a stamper here?  Are not the grooves inverse on a
stamper as well?  How is this process working, exactly?

I have never located a piece of analogue audio gear that was more accurate
(or anywhere near as accurate) in the time domain than a decent piece of
digital gear.  We're talking orders of magnitude more accuracy with
digital systems.  I must really be missing the idea of what is being
attempted here.  I'd love to be set straight because I clearly have a very
inaccurate and humorous picture in my mind.
