When you wrote AS I read A$.
There should be no skating force with a linear tracking (tangential) tone arm, except some side force has to drag it across the record. I am somewhat familiar with the Holbo deck which has both an air-bearing for the tone arm and another for the platter.
@asvjerry
Traversing a vertical warp momentarily increases the tracking force, then decreases it as the stylus goes downhill. With a pivoted tone arm, the skating force is proportional to the tracking force. In the extreme when the stylus gets airborne, it will be pulled away from the center by the anti-skating device, which tangential tracking arms do not need
