Latest Patents

Lee’s notable patent, titled "Magnetic transducer with electrically conductive shield for reducing electromagnetic interference," presents a novel design that incorporates an electrically conductive shield (ECS) situated between the substrate and the first magnetic shield. This innovative approach aims to mitigate electromagnetic interference, enhancing the performance of magnetic sensors in disk drives. The ECS is seamlessly integrated within an insulating undercoat layer, ensuring that it remains electrically isolated from the sensor element while being grounded through arm electronics.

Two connection methods for the ECS are outlined in his patent. The first method involves connecting the ECS through a via to a lead pad linked to the ground of the arm electronics, applicable only with single-ended input type arm electronics. The second, and preferred, method features a separate lead pad on the head allowing for secure grounding to electronic or case ground upon installation in the arm. The coverage area of the ECS is optimized to protect the read head portion of the transducer without impeding the write head pads.
