Title: Innovations of Motoichi Watanuki
Introduction
Motoichi Watanuki is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of magnetic head manufacturing, holding a total of 12 patents. His work has greatly influenced the development of advanced technologies in this area.
Latest Patents
Watanuki's latest patents include a method of manufacturing a magnetic head and a method of manufacturing a thin film head. The method of manufacturing a magnetic head is capable of correctly setting a raw bar, which includes small sliders, onto a supporting jig. This method allows for precise machining of the raw bars and improves the yield of manufacturing sliders. It comprises the steps of forming a magnetizable layer on a substrate whose thickness is greater than the length of the slider, followed by cutting the wafer into a raw bar after forming the layers.
The method of manufacturing a thin film head includes a protection layer that possesses sufficient corrosion-resisting and water-repellent properties. This ensures that the magnetic head remains clean even under high temperature and humidity conditions, while also providing durability and reliability. The process involves forming an adhesion layer on the disk-side face of a substrate, applying a protection layer, coating it with resist, and patterning the resist to create a pad hole. A pad film is then formed on the resist-coated faces, including the inner face of the pad hole, before lifting off the resist to complete the pad formation.
