Tony, I don't quite see your "one revolution" hypothesis. The platter once in play never comes to a complete halt. I think the point is that the motor needs to have "enough" torque to keep speed stable. And the definition of "enough torque" is related to inertial mass of the platter and servo design. In bd turntables, the belt/thread/tape is an added factor in the equation. In idlers it's the idler drive system.
Turntable speed accuracy
There is another thread (about the NVS table) which has a subordinate discussion about turntable speed accuracy and different methods of checking. Some suggest using the Timeline laser, others use a strobe disk.
I assume everyone agrees that speed accuracy is of utmost importance. What is the best way to verify results? What is the most speed-accurate drive method? And is speed accuracy really the most important consideration for proper turntable design or are there some compromises with certain drive types that make others still viable?
