Latest Patents

One of Vavra's latest patents is focused on heat-sinks for optical near-field transducers. This invention addresses the thermal energy generated within an optical NFT when it operates within a Heat-Assisted Magnetic Recording (HAMR) head. The heat-sink assembly is designed to extract thermal energy from the optical NFT and transmit it through convection to the surrounding air, radiation to adjacent surfaces, and conduction to other parts of the HAMR head. The air-bearing surface of the heat-sink plays a crucial role in convectively transferring thermal energy to the air passing between it and the adjacent magnetic medium.

Another significant patent by Vavra is a writer heater for thermal protrusion shape control in a magnetic writer. This transducing device features a storage interface surface and includes a writer with a pole tip region, a coil positioned around the writer, and a heating element. The heating element extends close to the storage interface surface and is designed to heat the writer in response to current flow, enhancing the performance of the magnetic writing process.
