Ti-Sn-Cr shape memory alloys were fabricated by the powder metallurgy (PM) process. The mixed powders in composition of Ti-3at%Sn-7at%Cr were prepared using a V-blender. The mixed powders were filled into a graphite die, and then sintered at a temper

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

We describe the recording characteristics of discs having Ge doped eutectic SbTe alloy recording films with various compositions. The recording characteristics are fairly sensitive on the film composition. For our recording condition, the Sb/Te ratio

A new method of eliminating the initializing process from phase change recording media production has been proposed. The process is based on the use of krypton instead of argon for the deposition of GeSbTe recording film. By this method the kinetic e
