Claim 26:
27. The method of claim 25, wherein the data storage device further comprises a second VCM, wherein the first VCM is a seeking actuator and the second VCM is a non-seeking actuator;
and wherein seeking the first VCM towards the target track in the first mode induces a coupled position error signal (cPES) in the second VCM, the cPES based at least in part on a motion of the seeking actuator coupling into the non-seeking actuator; and
wherein the first setting corresponds to a first PWM frequency and first slew rate combination, and the second setting corresponds to a second PWM frequency and second slew rate combination, and wherein the first PWM frequency is lower than the second PWM frequency and the first slew rate is higher than the second slew rate.
