<div dir="ltr">an interesting challenge - I'm not sure you could create a groove that is compatible with standard phono cartridges since that would require a fairly precise "V" shaped groove of the order of ~1mil. That's relatively straightforward for a lathe bit but I'm not sure a laser cutter has that kind of depth/width resolution. It would be interesting to try though. The quality would depend on how critical that "V" shape is and what the laser groove profile actually is. <div>
For stereo you would need transverse and depth modulation which are both possible. (Again just a question of profile)<div>You would also need an algorithm to convert the stereo waveforms to a mix of transverse and depth modulations since the relationship is not simple. ie. a phono needle separates left from right by measuring needle movements at a 45 degree angle to the surface normal.</div>
