Classification: CPC G | IPC G

Claim 29:
30. A data storage device, comprising:
one or more disks;
an actuator arm assembly comprising one or more disk heads and a first voice coil motor (VCM), the first VCM configured to operate in a first mode and a second mode, the first mode being different from the second mode, and wherein the first mode corresponds to a plurality of settings, including at least a first setting and a second setting;
a second VCM, wherein the first VCM is a seeking actuator and the second VCM is a non-seeking actuator; and
one or more processing devices configured to:
cause the first VCM to seek towards a target track in the first mode using the first setting for a first duration, 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;
control transition of the first VCM from under the first mode using the first setting to the second setting;
cause the first VCM to seek towards the target track in the first mode using the second setting for a second duration; and
control transition of the first VCM from under the first mode to a second mode, wherein controlling the transitioning comprises:
seeking the first VCM toward the target track in the second mode for a third duration.
