Latest Patents

Mitsuzuka holds a patent for a "Large-capacity magnetic memory using carbon nano-tube." This invention allows for high-speed writing and reading of magnetic records in a magnetic recording film. The technology utilizes a perpendicular magnetic recording system, enabling purely-electrically random access. The design incorporates a writing-magnetic-field generating means and a writing word line, which are strategically positioned relative to the magnetic recording film.

Career Highlights

Mitsuzuka's patent describes a sophisticated mechanism where a magnetic probe made of a carbon nanotube containing a soft magnetic material is used. This probe is positioned in a standing manner relative to a magnetoresistive-effect element. During the writing operation, a micro-discharge is generated, allowing a writing current to flow through a micro-gap. This process heats a micro-region of the magnetic recording film, enabling it to become magnetized and form a magnetic record.
