3D Printed Record?

I am known as a strictly vinyl man however I think I would sell files of my music if it was a to be printed into a physical object. Check out this video of a printed vinyl record! Although it's an interesting use of new 3D printing technology, the quality is far from good enough for hi-fi sounds. I wonder if a high resolution laser scan of an acetate dubplate and a high resolution 3D printer would do a better job? The vinyl in this video was produced by Amanda Ghassaei who converted audio files into a 3D image (ie. the grooves) via a sketch in Processing code.
