While this looks quite interesting, The phrase "Mechanically scratching audio grooves into a lacquer foil" is untrue and is part of marketing.
The way its done now, the groove is cut, not 'scratched' and its done with a heated stylus so its closer to what a heated knife does with butter.
Just sayin'.
But this does look interesting. Of course, cutting right to the stamper leaves you with the same problem of making duplicate stampers, so that's not likely how it will be done- instead the process has to go back a couple of steps to create a master that can be duplicated. That's going to involve plating and chemicals, despite the article's remonstrations.
