Title: Hiroki Aritomo: Innovator in Magnetic Head Manufacturing
Introduction
Hiroki Aritomo is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of magnetic head manufacturing, holding a total of 3 patents. His innovative approaches have advanced the technology used in various electronic devices.
Latest Patents
Aritomo's latest patents include a manufacturing method for a magnetic head that features a main pole and a write shield. This method involves forming a leading shield with a top surface that consists of first and second portions. The second portion is strategically positioned farther from the medium facing surface than the first portion and is recessed from it. A first gap layer is formed on the first portion, followed by the creation of a magnetic layer that includes an initial first side shield, an initial second side shield, and a coupling section connecting them, all using a mold. After the mold is removed, the coupling section is etched away from the magnetic layer. Subsequently, a second gap layer and a main pole are formed in sequence.
Another notable patent is related to a thin-film device that features a lead conductor film. This invention enhances the surface properties of the bump in the thin-film device. The thin-film element includes various components such as an electromagnetic conversion element, a passive element, and an active element. The lead conductor film, primarily composed of copper, connects to the thin-film element and is equipped with a bump. This bump consists of a first conductor film, which is either a tantalum film or made from a material with a fine crystal structure, and a second conductor film that is a plated film containing gold as a main component.
