"If the bearing is is the same plane, the tracking force is constant with the presence of such events."
I'm not sure I understand why this is so. Can someone help me understand why this is so?
I believe it is true if the pivot point is not at the center of mass of the arm. But if the pivot point is at the center of mass, then how does the tracking force depend on whether the pivot point is in the plane of the record.
(Say the center of mass and the pivot point are the same and they are in the plane of the armtube, which is above the plane of the record. And then there is a warp in the record. The cartridge rides up, but why should the tracking force change, other than from the acceleration of the cartridge's upward movement?)
