Abstract: The decoder/encoder comprises plural parallel magnetic domain compressor circuits. All the idler cells of the compressor circuits are initially filled with a magnetic domain. Decode circuit drivers which include current loops associated with selected idler stages are operated to trap domains in accordance with a code pattern. A domain output is obtained from the compressor circuits having no domains trapped in idler cells while the compressor circuits having domains trapped therein do not provide a domain output to a detector circuit.
