Abstract
An apparatus, according to one embodiment, includes a module having an array of transducers, and a thermoelectric cooling element positioned proximate to the array of transducers. An apparatus, according to one embodiment, includes a module having an array of transducers, a thermoelectric cooling element positioned proximate to the array of transducers, and a heating element positioned proximate to the array of transducers. A method of maintaining a span of an array of transducers of module to a specification, according to one embodiment, includes determining whether the span of the array of transducers in a module is different than a target based on a specification. In response to determining the span is greater than the target, a control signal is applied to a thermoelectric cooling element positioned proximate to the span of the array of transducers for contracting the span of the array of transducers toward the target.
