概要

論文の詳細を見る
Magnetic recording heads with a high-moment Co-Ni-Fe core are examined. Saturation flux density B_s of the core is 2.0 T. Good high-frequency write performance up to 500 MHz is obtained by reducing the core length to less than 10 μm. Excellent write performance of narrow (0.55 μm) pole tip head is also confirmed with high coercivity of a 480 kA/m (6000 Oe) medium. Finally, simulation results for higher-density and higher-speed magnetic recording are discussed.
