There is no getting around the simple fact

anything touching it for any extended period of time is
being exposed to very high temperatures.

I guess you didn't read the post where I worked out the geometry of the
situation.

Executive summary: The area being melted is like two 5 inch squares on the
surface of a 100+ foot diameter ball.

The claim that a stylus melts the vinyl passing beneath
it is just absurd urban legend.

Absurd urban legends that get published in refereed scientific journals.

It is perpetuated by
those who - for some odd reason - are simply driven to
distraction by the simple fact that millions of people
still enjoy LPs.

Yes, that was the motivation back in the 1970s when a lot of this was
published.
