Abstract
In a method of multi-rate tracking with a multi-actuator servo control, a track position error is sampled at an asynchronous sample rate for operating a first actuator. The track position error is also sampled at a synchronous sample rate for operating a second actuator. The sampling from the synchronous sample rate is utilized to reduce a delay associated with the sampling at the asynchronous sample rate.
