Abstract
A re-recordable data storage medium is disclosed. The medium in one embodiment includes a phase-changeable layer and an intermediate layer. A junction between the intermediate layer and another layer of the medium provides a conduction barrier under no illumination that is substantially diminished under illumination of the regions of the phase-changeable layer that are in the appropriate phase.
