Something that I've been curious about... We have all of these analog-lover people moaning and groaning about how they hate the sound of digital audio. While I am aware of the mathematics behind sampling, and I certainly don't think that I could hear any difference between a really good analog master and a normal CD of the same recording, the idea of keeping things analog still has a certain appeal. So would it be possible to have essentially an analog CD? Or, put another way, an LP that you read with a laser? Maybe where the laser was bounced off of the disc at an an angle so that it's reflected to a sensor, which is set up in such a way that it could capture even the tiniest variation in the height of the reflecting surface, thereby achieving the so-called infinite resolution of analog while still being read with the precision of a laser? (and the protective effect of a polymer coating that kept the actual recording-encoded surface free from dust, scratches, and other problems?) Does anybody know if this has been tried, or if it's in the works by someone who's still making a killing selling analog systems?
