Latest Patents
Yasuo Yoshida holds a patent for a magnetic head comprising a core formed of small and large thin films. This invention features a thin film magnetic head that includes a magnetic core of accumulation layers forming a magnetic circuit. The design incorporates at least two layers of magnetic film with specific magnetic characteristics. The unique construction of completely covering a magnetic film with a small pattern by a magnetic film with a large pattern results in a smooth edge part. This is achieved because the end of the underlying magnetic film is covered by the upper magnetic film. The edge-smoothing effect is most pronounced when using electrodeposition for the formation of magnetic films. By sequentially forming the magnetic films from smaller patterns to larger ones, the film formation benefits from the leveling action inherent in the electrodeposition method. This process allows for extremely smooth shielding while enabling pattern formation through a single step of photoresist coating, thereby shortening the production process.
