概要

• 論文の詳細を見る

• A Magneto-Optical recording technology is described for storage densities of 50-100 Gb/in^2 and data rates of 100-200 Mb/s.A sliding optical head which forms a key component for this recording technology has been developed.The head incorporates a thin-film coil for high data rate Magnetic Field Modulation recording and a dual lens objective with a Numerical Aperture of 0.85.To limit head-disc interface problems due to heating by the laser a cover layer of a few tens of μm is applied to the disc.Cover layer requirements are discussed and MFM recording results obtained with a NA=0.6 version of the sliding head and TbFeCo media with a thin cover layer are presented.
