ABSTRACT:
An optical information recording medium in which a inner layer is sandwiched between supporting plates and a number of recording portions formed of a recording material capable of recording information in the form of a hologram are rotatably arranged in the inner layer. The recording portion is rotated by electrifying its surface and an information beam and a reference beam are directed onto it from different angles to carry out angle multiplex recording. The surface of the recording portion is color coded with at least two colors. The color coding and rotation of the recording portions allow characters or images to be displayed. Electronic equipment using such an optical information recording medium is provided.
