摘要： 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.

摘要： In a particular embodiment, an optical transducer includes at least three optically conductive blades arranged symmetrically about a center gap. The optical transducer is adapted to receive polarized light from a light source and to focus the polarized light onto a recording medium while conserving polarization of the polarized light.

摘要： Metal alloy heatsink films for magnetic recording media are disclosed. The metal alloy heatsink films possess both high thermal conductivity and improved mechanical properties such as relatively high hardness. The metal alloy heatsink films also have controlled microstructures which are compatible with subsequently deposited crystalline magnetic recording layers. The films may comprise single phase CuZr or AgPd alloys having a selected crystal structure and orientation. The combination of high thermal conductivity, good mechanical properties and controlled microstructures makes the metal alloy heatsink films suitable for various applications including heat assisted magnetic recording systems.

摘要： Patterned thin films comprise regions of relatively low thermal conductivity material separated by regions of relatively high thermal conductivity material. The low thermal conductivity regions may be provided in the form of cylinders or cuboids which are arranged in a continuous matrix of the high thermal conductivity material. The thin film may be used as thermal control layers in data recording media such as heat assisted magnetic recording media.
