Why not use a non-contact stylus on a turntable?


I read comments about static-free playback of LPs with some amount of satisfaction.

When CDs were introduced, I quit worrying about the mechanics and started enjoying the music. More so with computer audio.

However, lots of folks like vinyl .... apparently. ;<)

Why not take all the worry, wringing of hands, and frustration out of the equation by insisting on touch-free stylus technology?

What is the technology? Hell if I know! But if nerds can sample the bits on a CD, they can sure as heck track the grooves on an LP!

Not only track the grooves, but filter out the grunge!

Play your oldest vinyl in complete background silence!

Put technology to work on vinyl! You’ll breathe easier for it.

Kind regards,

Greg

No. We're not talking about "survival".  The vinyl medium has a life of its own for many, many reasons, not all of them rational but most of them compelling to those of us who pursue the art, and so far sustaining.  Meantime, it seemed to me that you were asking for a way of reading the analog information encoded in a groove and transducing that mechanical information to an audio signal, without actually contacting the groove.  None of the advances in the art cited by Parotbee, except the laser turntable of which there is only one, have that goal in mind.  Nor did they get us anywhere nearer to it.  How do you get around the fact that nearly zero LPs are perfectly centered (this will throw off any noncontact reading device) and that all LPs will have some dirt particles or dust in the grooves?  These are problems that the developers of the ELP laser turntable have had to deal with.

But now I am not sure what you think we should want. (I won't say that you want it; you seem to be here to gloat.)  Most of us prefer analog to digital, but some use both media.  You can be forgiven for preferring digital, but beyond trolling, why are you here?  (As you can tell, I think there is no reason beyond trolling.)
A product of any one of the companies you cite might well be used to create a novel type of phono cartridge but can you say how one would read the information in the grooves without contacting the surface? That’s the crux of your issue, is it not? The ELP laser turntable does work, but as you’ve been told, it has serious shortcomings. You act and sound as if there were some very obvious solutions to what you think is a problem. Enlighten us. Or go away.
Greg, I think you levitated before posting.  You can come back down to earth now.  No free lunch, and no condescension needed.
