A disc drive microactuation system finely positions a transducing head carried by a slider adjacent a selected radial track of a rotatable disc. An electromagnetic microactuator having a stator and a rotor operatively connected to the slider is provided on a substrate. The rotor is movable with respect to the stator to effect fine movement of the slider. A magnetic shield layer is provided on the substrate for shielding the electromagnetic microactuator.
