The multiple motor approach is more applicable when the platter/subchassis/tonearm is suspended. It prevents the motor pulling the entire suspended mass towards itself when the stylus tries to slow the rotation of the record. It also allows alot of power to be applied to the platter without compromising the function of the suspension system.
In a non-suspended TT of the type that Romy is proposing that is less of an issue although if it is intended to use and transmit the power of a large motor to these platters, an arrangement such as F will prevent lateral wear/friction/noise in the bearings supporting them. However the motor and free running pulley will each be subjected to a uni-directional lateral force and may, in time become worn and noisy. It is still the configuration I'd choose of these options though.Rerurn to Romy the Cat's Site
