ABSTRACT:
Disclosed is an optical data storage device and system, and a method of doing one or more of entering data into, reading data out of, or erasing data from the device. The optical data storage device is characterized by an encapsulated structure including an optically non-transmissive, chalcogenide, phase changeable layer. The phase changeable layer is sufficiently thick such that the impinging vitrifiying energy pulse does not vitrify all the way through the layer.
