Möbius Record Player

There’s no B-Side!
  [vote for,

Given the spate of record player/vinyl/turntable ideas...

Möbius Record/turntable.

A ridiculously complex mechanical arrangement spins the vinyl. The groove passes the stylus to release beautiful music.

The “record” has just one side. No need to turn it over, and it plays continuously. Until you get bored of it.

       //ridiculously complex// it needn't be. All that is required is a pair of rollers between which the record passes, at least one of the rollers being actively driven.

       Hmm, yes, that’s actually feasible.
Frankx, Sep 30 2019

       Does the groove start at the inside or the outside?
pocmloc, Oct 01 2019

       //inside or outside//   

       Definitely, one or the other.   

       Actually this whole thing wouldn't work very well at all. Either you'd have grooves crossing at some point, or you'd only have a single groove covering [both the one sides] - which would make your play duration rather limited. Or rather, your loop duration. Could get very annoying.

I'm waiting for "Schrödinger's record player"...

       Is it too early for snowglobe record players?

       Wasn't there a ski jump return idea kicking around once?

       Hasn''t this already been baked? I want to say '8 track'.

       Ahh, memory via the build up of crossings as encoding, with added info as how track is cut.

       // Hasn''t this already been baked? I want to say '8 track'. //   

       Closest thing in playback mechanism (needle reading a grooved tape) would be the Tefifon and Tefi cartridges [link], but, as you can see at 3:20 in the video, that's not a Möbius strip. (It is coiled, meaning that would be a twisted loop if you pulled it out straight, but the number of half-twists would be even.) The same goes for 8-track [link], as you can see right the beginning of that video.   

       However, that's not to say that those two systems couldn't be adapted to use Möbius strip-shaped tapes inside slightly modified cartridges. You might get crosstalk between the 'two' sides of the one-sided magnetic tape in 8-track, though.   

       But this idea seems to me to be intended as a non-coiled Möbius strip (i.e. a total of one half-twist), with a strip width greater than 1/10 its diameter when laid out as a circle, and not contained in a cartridge.

       Obviously, the concept extends to the Klein-surface player, which picks up vibrations imbued into the surface of a pan-dimensional hyper-form. As the strange object is endlessly rotated through 4 dimensions, it retrieves pop sounds for make great benefit of all the youth.
