regarding the Tiger Paw tranquility

I am trying to understand the comments which seem to discuss the concept of 'slippage' due to magnetic coupling. Either I am missing this or they are. There is no magnetic coupling between the subplatter and the top main platter. The platters STILL are on top of each other. All that the magnets do is to introduce an upwards LIFT to the ENTIRE assembly. The main platter still FIRMLY sits on top of the subplatter. So, how is it possible to affect the speed in this scenario ? If the subplatter turns, the motion is 100% transferred to the main platter. There can NOT possibly be a slippage between them.

Please explain....

I suspect there is sufficient friction between the bearing and the platter to prevent slippage whilst record is playing.

@geoffkait Or maybe not??

At constant speed there are no longer the rotational forces incurred during start up to overcome inertia. As I understand it the design doesn’t attempt to levitate the platter, only relieve stress on the bearing. So some friction would be expected, no?
