In one embodiment, an apparatus includes a module having a substrate and a closure, an array of transducers in a thin film structure on the substrate, the array being positioned along a tape bearing surface of the module, and a heating element positioned in the thin film structure and recessed from the tape bearing surface, and a controller electrically coupled to the heating element. The controller is configured to apply a current pulse of size, shape and duration sufficient to induce a permanent expansion of the array of transducers.
