As  a first step, we convert a high-resolution audio file into a topographic 3D map.  Because we know the exact width of the amplitude at any time,  we can virtually remove unnecessary gaps between the grooves. 

We  can also correct the tangential/radial error caused by the fact that the lacquer is traditionally cut at a tangential angle, but most turntables read in a  radial angle. This results in a constant tilt of the needle. 

This groove optimization results in 30% more playing time.  Or, we can use the additional space to create a completely augmented listening experience by increasing the amplitude.  The result is that HD Vinyl has far better dynamics and much better S/N ratios.

Once optimized, the 3D topographic map will be engraved with a high precision laser onto a ceramic plate. No more toxic electroplating necessary. 

Opposed to a traditional etcher, a laser cannot overheat and thus cuts finer structures. We can cut up to 100kHz onto the outer edge of the disk.  By comparison, a traditional vinyl record can realize a maximum 15kHz, losing higher notes.

We use ceramic materials for the stamper.  This ensures that there’s no quality difference between the first and last copy produced.  

In the traditional vinyl pressing process, a nickel stamper has to be replaced after a maximum of 1,000 copies because of wear.  Even worse, there’s a huge quality difference between copies no. 1 and 1,000.  That’s one of the reasons why vinyl collectors pay more for earlier copies.  

With HD Vinyl there’s no such quality difference: the first and the last copy have the absolut same high quality.
