I doubt that a non-contact player would be the "best of both
worlds."  While it would solve the wear problem and the problems
associated with the resonant mechanical systems, and even assuming it
introduced no new problems of its own, it could not solve the noise
problem of vinyl discs. They would still attract dust and be amenable
to holding dirt. they could still suffer physical damage from things
like spoons (they hold the jam the kids are smearing on the record, did
you expect them to use their fingers?). These physical things would all
interfere with a laser pickup at least as much as they now do the stylus,
maybe more. Now, maybe if you coated the disc with a clear layer of
vinyl like they do with cds...but then everyone would have to use the
laser pickup because needles wouldn't work.
What I think we need is a real solid state memory for digitally encoded
music, so we could get rid of the moving parts. Bubbles?
