<p>The method and apparatus for recording 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 desired portions of the layer of memory material in accordance with a desired pattern of useful information, energy is applied to the layer for activating the catalytic material at said desired portions of the layer and physically changing the layer at said desired portions from said one detectable structural condition to said other detectable structural condition to record the desired pattern of useful information in the layer.</p> |
