I don't understand why you think tracking error causes skating force. Take a look at the tonearm in the diagram. It has no skating force although it has about 15-degrees of tracking error. The groove tangent at the stylus, shown as vector Ft , is aligned perfectly along the stylus/pivot axis of the tonearm. Therefore, there can be no skating force. There can be no skating force from stylus/groove friction, no skating force from groove undulations, and no skating force from tracking error. I'm bewildered that you don't understand this.
