Title: Mitsuo Kawasaki: Innovator in Thin-Film Magnetic Head Technology
Introduction
Mitsuo Kawasaki is a prominent inventor based in Niigata-ken, Japan, known for his significant contributions to the field of magnetic head technology. With a total of 10 patents to his name, Kawasaki has made remarkable advancements that have influenced the design and functionality of magnetic recording devices.
Latest Patents
One of his latest patents is a thin-film magnetic head that locally projects an element part toward a recording medium by thermal expansion. This innovative design includes a reproducing element formed on an undercoat film on a head substrate surface, a recording element positioned above the reproducing element, and a heater that generates heat upon energization. The heater projects the reproducing element toward the recording medium through thermal expansion. Additionally, a shield layer is strategically placed between the reproducing element and the heater, consisting of multiple layers, including first and second shield layers. The second upper shield layer, located closer to the heater, is made from a material with a smaller coefficient of thermal expansion than that of the first shield layer, which is closer to the reproducing element.
Another notable patent involves a method of manufacturing a thin-film magnetic head using a soft magnetic film with high saturation magnetic flux density. This soft magnetic film is composed of a CoFe alloy with an iron content ranging from 68 to 80 mass percent, achieving a saturation magnetic flux density of 2.0 T or more. The film's surface has a center lain average roughness of 9 nm or less, enabling the creation of a corrosive-resistant magnetic head with high recording density.
