That describes the operation of my old Stanton.

The Mag-Lev concept is just complete nonsense, with a dangerous dynamic magnetic field that can never properly control or constrain the platter. The platter is perfectly free to move & wobble in ANY direction, and from videos it does this quite a bit.
