That's theoretically possible.... but the resolution you'd need would be staggering. (Remember that the resolution you would need is NOT "the size of a groove". In order to deliver a S/N ratio of a mere 60 dB, you would need enough resolution that you could "see" when the side of the groove moved less than 1/1000 of the overall width of the groove itself. A quick "doodle on a napkin" calculation tells me that you would need a scanner or camera with a resolution on the order of several MILLION dots per inch to even come close. You might get that with one of those new cameras they're using on drones to watch entire towns.... but the price would obviously be prohibitive.)
In contrast, a LASER "turntable" that tracks the groove needs to be able to deliver that much resolution, but only over the less than 1/1000 of a square inch where the stylus would normally contact the record, and not over the entire surface of the record at once.
The OP is killing time waiting for all the hurricanes to blow over
Perhaps, if so my prayers are with all in its path! But perhaps the OP is killing time waiting on the RMC-1? Perhaps!
We don't got no hurricanes here in Sydney, no typhoons neither, there is the odd cyclone about 2,500 kilometres north but less frequently now thanks to climate change (it's true, check it out).
Sorry to disappoint you Nick, but mathematically there's way more chance of me buying a turntable that's lasts for decades, than there is buying an RMC-1 that lasts a few years. Even at 3 times the price the value over time equation easily favours the turntable.
