Do 45 RPM records need higher anti-skate setting?

Lewm, I think the part about centrifugal force to be a red herring. We don't need to discuss it further.

Ralph, I have spent a lifetime stamping out "centrifugal force", ever since my freshman physics professor hammered it into me about the First Law. I can't stop now. Centripetal force needs my help and support.

An object once set in motion...

So far John's argument about variable friction does not seem to be addressed, or did I miss something?

I've had conversations with several tone arm manufacturers; they seem to agree that there is no standard for anti-skate forces to be applied to an arm. Put another way they all seem to have different ideas about it.

From a simply pragmatic point of view, the phenomena of the OP is that increasing the force fixed a problem that did not seem to exist at 33 rpm. Was that simply because he had not played anything with that complexity prior? Or was it because the forces on the arm were different?

Skating force is generated by the friction between the stylus and the vinyl. That's it. I researched it a few years back and learned that the coefficient of friction, which will determine the friction force generated, varied widely like from 0.1 to 0.5 among different records up until the 50s. Since the late 50s the coefficient of friction has been pretty consistent- about 0.20-0.25. That would result is some milligram differences in skating force from record to record. That being said, I have a couple of records and perhaps it is more about their dynamic range, that I have to turn the anti-skating setting up a tad because I will here a little bit of distortion in the right channel. That does the trick. By the way, one of those records in my mind is recorded at 45 rpm incidentally. It is the Apassionata and it is very dynamic. It is an RCA direct to disc. Very high on the goosebumpometer.
