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.
