概要

• 論文の詳細を見る

• An optical flying head having an integrated magnetic field modulation coil and high-numerical aperture (NA) lens has been developed. This component can be used for first-surface magneto-optical (MO) recording with a NA of 0.9 and a wavelength of 405 nm. To achieve highly precise tracking with this system, we developed a track-access mechanism that has a sled positioner and a galvano mirror. The experimental use of a dual-stage control technique resulted in a tracking error of 10 nm.
