Back in the days of vinyl, the "master disk" was a record made of metal
(aluminum? steel?), mixed from the original tapes. From this, the
record company would make molds for the actual disks that were sold.

Yes, but that's not the "master" in "re-master;"

Right, you don't want to use a master tape equalised for vinyl to cut a CD
anyway, and certainly not a disc copy, unless nothing else remains!

it's the master tape, the final mix-down.

Depends what you call the "final" mixdown, and the best remasters go back to
the original multi-track and remix anyway.
