A write driver circuit for a magnetic storage medium includes a first write driver sub-circuit that has an output that communicates with a first node of a write head. The first write driver circuit includes a first driver circuit and a first feedback path between the input and the output of the first driver circuit. A second write driver sub-circuit has an output that communicates with a second node of the write head. The second write driver sub-circuit includes a second driver circuit and a second feedback path between the input and the output of the second driver circuit. The write driver circuit has a substantially constant output impedance during operation, balanced differential and common mode resistances, and a substantially constant common mode voltage across the write head during operation.
