Where'd you get Magnetic Drive? What Clearaudio offers is a ceramic magnetic bearing. From the english version of their German website:
Ceramic-Magnetic-Bearing
The Clearaudio CMB (Ceramic Magnetic Bearing) is a result of long-term research and development and is based on a Clearaudio patent. Two aligned opposing magnetic fields are perfectly aligned one on top of the other, thereby rejecting each other. The magnetic fields are completely shielded from the outside through the careful application of very sophisticated materials. A high precision ceramic vertical axe fits perfectly into a bronze bearing. This perfect fit is essential and can only be achieved through the highest precision hand polishing.
High-performance synthetic oil is used for lubrication. The combination of these carefully selected components produces the effect of the platter floating by itself on an air cushion, and not on a ball bearing or bearing point.
The results of this magnetic bearing are one of the lowest frictions in turntable bearing design and until now, un-reached rumble measurements, and an unbeatable new standard in speed accuracy.
