ABSTRACT:
A three-dimensional combined magneto-optic memory and logic processor consisting of layers of magnetic bubble material spaced from and parallel to one another. Each layer has a pattern of magnetic bubbles formed under the control of an external data processing system. A laser beam is directed through the layers, and binary signals corresponding to the overall patterns of the magnetic bubbles on all the layers which intersect the beam are detected by a first detector array. Data and logic functions are programmed on to each layer by appropriate control of the magnetic bubbles by the external processing system. Wave guides are provided to reflect light from the magnetic bubbles to a second detector array. In this manner, the two detector arrays may be caused to generate electric signals representing data and logic functions, thereby eliminating the bottle-neck between processor and memory which is prevalent in prior art data processing systems.
