Abstract
An associative data processor including a spin glass type amorphous magnetic film has input areas, output areas, and "hidden" or associative areas. A coil provides selective magnetic biasing, and lasers provide selective digital input to the input and output areas, which are intercoupled by the associative areas. Following input of a number of digital patterns to the processor, and "learning" by heating the associative areas, an incomplete input pattern may be applied, and the complete pattern read by sensing the polarization of reflected polarized light from the output areas.
