Abstract: The method involves detecting the integration function of a positioning error signal loop, and actuating the coarse actuator so that a fine actuator and a head unit are displaced w.r.t the detected integration function. Independent claims are also included for: (a) a further method for actuating a coarse actuator in a servo system (b) a servo system (c) a data storage system (d) a servo coarse controller
