Latest Patents

Okazaki holds a patent for a large-capacity magnetic memory using carbon nanotubes. This high-capacity magnetic memory is capable of writing and reading magnetic records in a magnetic recording film according to a perpendicular magnetic recording system. It operates at high speeds in a purely electrically random access manner. The design includes a writing-magnetic-field generating means and a writing word line relative to the magnetic recording film. Additionally, a reading/writing bit-line conductor, a magnetoresistive-effect element, and a reading word lead conductor are laminated on a probe substrate. A magnetic probe composed of a carbon nanotube containing a soft magnetic material is positioned relative to the magnetoresistive-effect element and is electrically connected to the reading/writing bit-line conductor.

During the writing operation, a micro-discharge is generated in a micro-gap between the edge of the magnetic probe and the magnetic recording film under a writing magnetic field. This allows a writing current to flow through the micro-gap, heating a micro-region of the magnetic recording film to its Curie point, thus magnetizing it in the direction of the recording magnetic field. The reading operation involves reading the magnetic record through the magnetic probe based on current variations in the magnetoresistive-effect element.
