In one embodiment, a magnetic head includes a write pole; a write coil adapted for causing the write pole to emit a magnetic field upon excitation of the write coil; and a first capacitor and a second capacitor electrically connected in parallel with the write coil, each capacitor including a planar bottom plate, a top plate positioned parallel to the bottom plate, and at least one dielectric layer positioned between the top plate and the bottom plate, wherein a parasitic capacitance between the bottom plate of each capacitor and a substrate positioned below the bottom plate exists during writing operations of the magnetic head, and wherein the parasitic capacitances of the capacitors are about balanced.
