A transducer comprises a conductive pin and a waveguide for directing electromagnetic radiation onto the pin, wherein the pin is configured to create a rectangular flat top field distribution at a surface of a storage medium positioned adjacent to an end of the pin, leading to a flat top thermal profile within the storage medium. A second pin can be included in the transducer. Recording heads that include the transducer, disc drives that include the recording head, and a method of heating a portion of a storage medium that is performed by the recording head, are also included.
