Data recording device incorporating micro-points for recording on an active film of a germanium-antimony-tellurium to provide high density storage for information and multimedia applications

摘要

Data recording device incorporates some micro-points 93) and a recording support (2) comprising a substrate (4) on which is disposed a resistive layer (5). The resistive layer is covered with an active layer (6) capable of passing from a first value of electrical resistivity to a second value under the action of a voltage applied between the micro-points and a counter-electrode. At least one resistive element (7) of carbon is arranged between the active layer and the micro-points.
