Title: Otto Vogeli: Innovator in Magnetic Recording Technology
Introduction
Otto Vogeli is a notable inventor based in Morgan Hill, CA (US). He has made significant contributions to the field of magnetic recording technology, holding a total of 2 patents. His work focuses on enhancing the stability and efficiency of magnetic recording heads.
Latest Patents
Vogeli's latest patents include a CPP magnetic recording head with a self-stabilizing vortex configuration. This innovative design features a CPP MTJ or GMR read sensor where the free layer is stabilized by a circumferential vortex magnetization. This configuration allows the pinned layer to be magnetized parallel to the ABS plane, enhancing its directional stability. The absence of lateral horizontal bias layers or in-stack biasing enables the creation of closely configured shields, providing protection against side-reading. The vortex magnetization process involves initially magnetizing the free layer in a uniform vertical field, followed by the application of a vertical current while the field remains active.
Another significant patent by Vogeli is a method for forming a CPP magnetic recording head with a self-stabilizing vortex configuration. This method mirrors the features of his latest patent, emphasizing the importance of the circumferential vortex magnetization in achieving a stable and efficient magnetic recording head.
