Outline of Final Research Achievements

For heat-assisted magnetic recording (HAMR), write head structure with dent for optical element, short yoke, and soft magnetic underlayer was proposed, which worked for high-frequency recording current. The maximum areal density of 8 terabit per square-inch was predicted with the write head.
For microwave-assisted magnetic recording (MAMR), tilted, not perpendicular to the media plane, spin-torque oscillator (STO) inserted into the tilted write head gap was proposed. The head had a large recording field and stable STO oscillation.
