The heat sink structure prevents heat generated by the magnetic oscillator current from causing damage to and reducing reliability of the magnetic write head. The trailing magnetic shield is substantially aligned with the magnetic oscillator, allowing the heat sink structure to wrap around the sides and back of the trailing magnetic shield and to provide good heat conduction away from the write pole, magnetic oscillator and trailing magnetic shield. The heat sink structure can be constructed of a material such as Ru, TiN, Cu, Au, Ag and AlN, and is preferably constructed of Au, which has excellent thermal properties."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Microwave assisted magnetic recording head with trailing shield heat sink","description":"A magnetic write head having a heat sink structure located adjacent to a trailing magnetic shield.
