Abstract : The report describes a combination digital display and memory element comprising a thin film of magnetic material having a uniaxial anisotropy, a matrix of crossed conductors, and a thin film of rotatable anistropic magnetic material having a dense banded domain structure. A coloidal suspension of ferromagnetic particles covered with a transparent chamber is placed over the magnetic material. Light directed at the cloidal suspension will be reflected to produce an image of the domain structure contained in the magnetic films. The domains are selectively produced by generating currents on the crossed conductors. (Modified author abstract)
