Skating is where the stylus is pulled towards the center of the record. This is caused by a difference in friction between the inner and outer groove walls. Thus an inward momentum is imparted by the LP's center-spiraling groove on the pivoting tonearm. An anti-skate mechanism counterbalances this force. The force will vary depending on the stylus' distance from center (radius) and the tracking force.

For linear tracking tonearms, a non-pivoting arm rides a perpendicular path to the grooves in the record. Because the arm isn't pivoting on an interesecting radius, there's no difference in friction between inner and outer groove walls. Therefore, linear tracking tonearms are not subject to skating.

See the link below for a brief explanation of the physics at work.

How can there be a centrifigal force on the stylus--it's not moving. - jeffreybehr 15:57:49 03/14/07 (1)

but i do mean centrifugal force. intuitively it seems that - snkby 20:52:20 03/14/07 (0)
