We introduce a novel vertically stacked lead structure for multiple head/track systems which can reduce inductive coupling between lead pairs by several orders of magnitude. We develop an analytical expression for the coupling of both vertically stacked and conventional side-by-side lead pairs, and compute the inductive couplings. The sign as well as the magnitude of the mutual inductance between lead pairs depends on their relative displacement. This dependence provides opportunities for cancellation. Also, because of the balance between positive and negative contributions to the mutual induction, the coupling between lead pairs does not necessarily decrease monotonically with distance. The results presented here provide design information for the tradeoffs between crosstalk, spacing, and fabrication costs.
