Title: **The Innovations of Inventor Junjie Quan**
Introduction
Junjie Quan is a prominent inventor based in Fremont, California, known for his remarkable contributions to technology and magnetic reader structures. With a total of 11 patents to his name, he has significantly impacted his field through innovative solutions and designs.
Latest Patents
Among his latest innovations is a patented design for a hard magnetic stabilized shield tailored for double (2DMR) or triple (3DMR) dimension magnetic reader structures. This invention discloses a unique hard magnet stabilization scheme for top and junction shields. The hard magnet adjoins either the top or bottom surface of part of a shield domain, ensuring it is recessed from the air bearing surface to meet reader-to-reader spacing requirements. This design stabilizes a closed-loop magnetization within the top shield. The patent further includes provisions for the hard magnet’s dimensions, ensuring that its height and width exceed those of the top shield. Additionally, the top shield may come in a ring shape, with the hard magnet positioned strategically above, below, or inside the ring, enhancing the stabilization of vortex magnetization. Notably, the magnetization can be set or reset from room temperature to 100°C to maintain an optimal magnetization direction in the sensor's top shield, junction shield, and free layer.
