In disk files employing start-stop in contact magnetic transducers, a relatively high torque is required to accelerate the stack of magnetic disks up to their normal operating speed in a relatively short period in order to avoid prolonged contact between the magnetic transducer and the surface of the associated disk. The torque required to maintain the disk spindle at a precise synchronous operating speed is generally much lower.
