Title: Chang-Man Park: Innovator in Magnetic Technologies
Introduction
Chang-Man Park is a prominent inventor based in Mountain View, CA (US), known for his significant contributions to the field of magnetic technologies. With a total of 10 patents to his name, he has made remarkable advancements in the design and manufacturing of magnetic heads and sensors.
Latest Patents
One of his latest patents is titled "Magnetic tunnel junction having a magnetic insertion layer and methods of producing the same." This invention describes a magnetic head that includes a barrier layer with a crystalline structure, a first magnetic layer above the barrier layer, a magnetic insertion layer above the first magnetic layer, and a second magnetic layer above the magnetic insertion layer. The second magnetic layer features a textured face-centered cubic (fcc) structure. The first magnetic layer is composed of a high spin polarization magnetic material, which has a crystalline structure that closely resembles that of the barrier layer. Additionally, the magnetic insertion layer consists of a magnetic material with a crystalline structure that is more similar to the second magnetic layer than to the barrier layer. This patent also outlines various additional magnetic head structures and methods for producing magnetic heads.
Another notable patent is the "Method for manufacturing a magnetic tape head using a TMR sensor." This method involves creating a magnetic tape head that incorporates both a data sensor and a servo sensor. The sensors are separated from the magnetic shields by a non-magnetic gap layer, with the gap thickness for the servo sensor being larger than that for the data sensor. The process includes depositing a first gap layer over shield structures, followed by a second gap layer using a liftoff process. A series of sensor layers are then deposited, and a mask structure is formed to define the stripe height of the sensors. Ion milling is performed to finalize the stripe height and remove excess gap material.
