概要

• 論文の詳細を見る

• A new type of MAMMOS (Magnetic amplifying magneto-optical system), which operates under the DC magnetic field in reproducing process, was proposed and evaluated.In this system, the CNR of 43 dB was obtained for 0.25 μm packed domains by applying 10 kA/m of DC magnetic field.Compared with conventional CAD (Center aperture detection)-MSR (Magnetically induced super resolution) disk, it was shown that the CNR for domain size below 0.4 μm was greatly improved.
