Patent abstract
A data recording component includes a read transducer and a write transducer. A thermoelectric device generates heat flow between the read transducer and the write transducer. The heat flow is conducted by thermal conductors. A controlled current source provides current to the thermoelectric device that changes polarity to change directions of the heat flow and thereby vary a gamma ratio of transducer protrusion.
