Patents Filed for ‘High Definition Vinyl’ Technology

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. 

I would think new geometry would be in order if this is to come to be.

So if it is burned with a laser, does that mean it must have a DAC involved. I know a lot of vinyl today is done from files, but this method sounds like it will eliminate any possibility of a pure AAA recording chain. This may not be bad IF the increase in resolution is fully realized AND they are using high res files. Otherwise it won't help vinyl quality.

The geometry won't be any different.
