Toroidal vinyl record player

 Innovative
 
(0) 		  [vote for,
against]

In this record player, the recording grooves are on the inside of a toroid. The stylus pickup is permanently installed inside the toroid, powered by magnetic induction, with the audio signal being relayed to the amplifier through the structure of the "record" using a split transformer similar to the rotary transformers used in videotape recorders.

Since the toroid is sealed, the groves never need cleaning as no dust can enter.

       The pickup does not 'rattle round". It's attached to a moveable carrier with wheels that press against the inner surface of the torus.

       So, it's not meant to rattle? Do you have a returns department?
—MaxwellBuchanan, Sep 30 2019
   

       Yes, the details are on the stylus mount.

       Whatever. We'll just send it back to the same place we sent that self-assembly dining table. It never did.
