Title: Lijun Tong: Innovator in Magnetic Recording Technology
Introduction
Lijun Tong is a prominent inventor based in Fremont, California, known for his significant contributions to the field of magnetic recording technology. With a total of six patents to his name, he has developed innovative methods that enhance data storage and retrieval systems.
Latest Patents
Among his latest patents is a method of forming a dielectric slope for energy-assisted magnetic recording (EAMR) writers. This patent discloses a structure that includes a bottom cladding layer and a near-field transducer (NFT). The process involves forming a patterned sacrificial layer over the structure, followed by the deposition of a top cladding layer. A patterned resist is then created over the top cladding layer, allowing for a first etching operation that results in a sloped region. This innovative approach improves the efficiency of EAMR writers.
Another notable patent is for a compact MR write structure. This invention features a conductive shield layer, an insulating write gap layer, a pole pedestal, a coil, and a conductive pole layer. The design allows for a self-aligned array of components that can be formed in a single masking operation, ensuring tight tolerances and a shorter yoke length. This compact design is crucial for enhancing the performance of magnetic data storage and retrieval systems.
