摘要： Data storage device comprises a substrate and a chalcogenide data storage medium encapsulated in a dielectric, the medium being reversibly switchable between detectable states by an energy beam. The medium comprises a chalcogenide and a crosslinking agent. The dielectric is pref. a graded oxide, being stoichiometric adjacent the medium and suboxide away from it; the dielectric may be layered or continuous and is pref. GeOx.

摘要： @ Disclosed is a data storage device having a chalcogen data storage medium encapsulated along at least one surface, and preferably both surfaces, by a dielectric barrier layer. The dielectric may be compositionally graded in oxygen content with respect to the chalcogen data storage medium, a substantially stoichiometric oxide in proximity to the chalcogen data storage medium, and a substantially non-stoichiometric suboxide remote from the chalcogenide data storage medium. The state changeable chalcogenide layer may have a morphology enhancing component in contact therewith. The data storage medium may be substantially oxygen free and comprise a chalcogenide, a cross linking magnet, and a switching modulator. The switching modulator is a transition metal, especially from the right hand column of Group Vlll, e.g. nickel, palladium, and platinum. The concentration of the switching modulator in the data storage medium is high enough to suppress grain growth during written storage, to provide random crystallite orientation and to increase the erase velocity, but low enough to permit discrimination between detectable written and erased states of the data storage medium. Also disclosed is a method and apparatus for depositing material on a substrate by periodically measuring an optical property of a region thereof, thereby obtaining a substantially continuous profile of the property for that region. The measured value of the property is compared with a predetermined value, and when the two values are substantially equal, deposition is terminated, thereby resulting in correct and reproductible layer thicknesses.

摘要： A data storage device having a chalcogenide data storage medium is being reversibly switchable between detectable states by beam energy encapsulated in a dielectric layer.
Energy projecting means project energy onto said data storage medium at a first energy density and duration for conversion into the written state, at a second energy density and duration for conversion into an erased state, and at a third energy density and duration for determining the states. The data storage medium comprises also a cross linking agent and it has an erased-noise signal ratio invariant of the written storage time.
The contrast ratio is substantically invariant of the history. The erase velocity is less than 1 µs.
