Those grooves that will now be played back wear free still exhibit the limitations of the cutter head and the medium in general. You're still moving a big massy hunk of metal around to cut the grooves. Why not move some electrons around instead? LOTS less massy. LOTS easier to get flat response. Laser LP readout sounds like RCA's audio/video disk fiasco in reverse. There they had a neato digital encoding scheme that was read by a capacitive sled stylus on a pivoted arm. Kludge City. They were laughed out of the market. Why bother with a new transduction method if it doesn't fundamentally improve both playback AND recording accuracy?
