Turntable Question - Centrifugal or Centripetal?

Posted by: Lapdog on 26 May 2005

Quickie for ya,

What force is being applied to the stylus as it rides the groove of the record?

A smarty at works said without a doubt that it is centrifugal and that may well be true if the cart sat on the record surface (all on its lonesome) but I’m guessing that because the cartridge being fixed to the tonearm headshell kinda changes the dynamics and the force being applied is actually centripetal.

I know I know… silly question,

Odd that CDs etc read TOContents near centre and laser tracks out to periphery towards infinity.

So much is probably going on around electromagnetism of headshell/cartridge, including 'springiness', that theoretical centripetal force/bias/antiskating are just a couple of variables in vinyl replay (not counting springy-suspensions/some springy rooms...).
