Apparently there is talk of developing “HD Vinyl”…
Imagine a vinyl record that has 30% more capacity, 30% greater volume, and double the audio fidelity of a typical LP sold today.
The layers of irony inherent to this concept are many:
The HD Vinyl process… involves… perfecting the topographic, computer-generated, 3D modeling imprint before any physical manufacturing takes place. “We adjust the distance of the grooves, we correct the radial/tangential errors, and we optimize the frequencies,” Loibl continued. “You could say we ‘master’ the topographical data, which is a totally different approach.”
After that, a ‘pulsed high-energy Femto-laser’ burns the audio directly onto the stamper.
Over a year ago, I was pondering on the idea that the way hi-fi was going, we would end up with 3D-printed phonograph cylinders. I am glad that the process is well under way.
