ABSTRACT:
An apparatus for concentrating electromagnetic energy comprises a metallic transducer including a first section and a second section, wherein the first section is wider than the second section and has a width to length aspect ratio greater than or equal to a width to length aspect ratio of the second section, and a condenser for directing electromagnetic radiation onto the transducer. A magnetic storage device that includes the apparatus is also provided.
