I can see lots of potential musical problem. Doesn't mean they haven't or can't solve them. Nick should comment, he is building a TT at the moment, he will have a handle on this.

it might be precise but what about magnetic field would that not interfere with rest of the gear I thought cartridge is based on magnets... ? having one big moving magnet next to tiny ones seems like big no no

That is one of them, but for me it would be disturbance in the air of any sort. A badly designed TT has mechanically coupled disturbance problems, where as any movement of air will disturb this, even walking past it, and it will take a while to settle back, and any platter movement will disturb the music, making a much bigger problem to note pitch stability than any belt. Look at the continuous oscillation in the platter when he touches it, do people really think you can't hear this.

The marketing is very flash, it looks to me like a way to make money and then say the idea didn't work and keep all the investment. i.e. - a con.

As i said elsewhere, I am not sure just what problem this is trying to solve (other than create a good marketable hook).

Assuming the magnetic fields are not at LHC levels, it will restrict the mass of the platter, which will restrict the rotational momentum, so W&F will be interesting. Also, I see major problems centring the platter rotation, and controlling the speed. Given that a stylus is measuring movement in the 10^-8m range, keeping it all steady will be a serious problem.

That's it there is only a problem of how to con people out of their money - they might even succeed on that one...

For what it's worth there was a working prototype shown here in Ljubljana last year (on the annual HI-FI show).

So yes, it does exist and it does work.

However I don't think it was ever intended/marketed as an audiophile record player, but rather as a "new" way to play your records.
All to do with the current vinyl resurgence...

Far more interesting was a "vertical" (as in - you can hang it on your wall) record player presented a couple of years ago. That one was intended as a high-end product and indeed sounded rather brilliant. Sadly it never made to mass production...

Here is a picture of the said vertical turntable:

I remember a few juke-boxes that played the single vertically. And Project have a vertical player on their book.
