High-Speed Deposition of New Low-Refractive-Index Dielectric Film 'SiOC' for Rewritable HD DVD Media
Publikováno v:
Japanese Journal of Applied Physics. 45:1447-1451
A low-refractive-index film plays an important role in attaining a high density of rewritable HD DVD optical recording media, for which the blue-violet laser of 405 nm wavelength incident on a 0.6-mm-thick substrate is used. We have developed a new l

We attempted to improve phase change media to achieve larger capacity for systems with blue lasers using numerical apertures (NA) of both 0.85 and 0.65. It was found that the Bi-added GeTe-rich pseudo-binary composition promised high erase ratio even

We have developed optical recording media for high-speed operation on the HD DVD rewritable (HD DVD-R) format, which uses a laser wavelength of 405 nm, a numerical aperture of the objective lens of 0.65 and a cover layer thickness of 0.6 mm. In this

Fe layer thickness dependence of the interlayer exchange coupling across a Au spacer is investigated for MBE-growth Au/Fe/Au/Fe/Au(001) films involving two step-shaped Fe layers with each step 1 ML high. The coupling strength oscillates as a function

We have used molecular beam epitaxy apparatus to grow Fe-Si films. The films were grown by first depositing a nominal 40 A of Fe, then a nominal thickness of Si, then a further nominal 40 A of Fe. A plot of the ratio (remanent magnetisation/saturatio
