ABSTRACT:
The method and apparatus for recording and retrieving information includes a layer of memory material which normally has one structural condition having one detectable characteristic, which is capable of having portions thereof physically changed to another structural condition having another detectable characteristic, which has internal biasing forces toward said other structural condition, and which has internal inhibitions against the action of said biasing forces. The layer of memory material is provided with a catalytic material which is catalytically capable of relatively increasing said biasing forces and decreasing said inhibitions against the action of said biasing forces of the memory material. At at least portions of the layer of memory material, energy, including electrical energy, is applied to the layer for activating the catalytic material at said at least portions of the layer and physically changing the layer at said at least portions from said one detectable structural condition to said other detectable structural condition to record the information in the layer. The structural condition of the at least portions of the layer is detected to retrieve the information in the layer.
