Title: Sigeo Hara and Magnetic Head Support Technology.

Introduction

Sigeo Hara is an inventor associated with Minamiashigara, Japan, and Hitachi, Ltd. His patent work includes a design intended to help a magnetic head slider float stably above a recording surface.

Latest Patents

Hara is credited with 1 patent, titled “Structure for Supporting Magnetic Head.” The invention describes a gimbal member that carries a core slider and includes a loading projection, together with a loading beam that presses against the projection to urge the slider toward a recording medium. By offsetting the beam’s contact surface from the surface connected to the gimbal, the design reduces the height difference between the slider’s plane and centroid. This helps reduce the moment acting on the slider as it moves, supporting stable flotation without inclination relative to the magnetic recording surface.

Career Highlights

Hara’s listed patent reflects work on magnetic recording hardware, particularly the mechanical support and positioning of a magnetic head. The patent identifies Hitachi, Ltd. as his company affiliation.

Collaborations

Hiroshi Daito is listed as Hara’s coworker. The available information does not specify their roles or describe a particular joint project.

Conclusion

Sigeo Hara’s recorded invention addresses a practical challenge in magnetic recording by refining the support structure to promote stable, level movement of the magnetic head slider.
