摘要
A storage angular multiplexing apparatus for hologram data storage having an angular multiplexing apparatus with a high response speed instead of a precision rotating apparatus constituting a storage device for storing hologram data is disclosed. A reflecting mirror for reflecting the laser beam applied from the laser beam generating unit at a predetermined angle is provided on the upper surface of the rotating flat plate and the rotating flat plate is rotated at a constant speed by the rotating motor so that the reflecting mirror rotates at a constant speed do. The microcomputer controls the operation of the laser beam generator according to a signal applied from the rotation angle sensor so that the irradiation of the laser beam is interrupted according to the rotation position of the reflector, . Therefore, the irradiation of the laser beam is controlled by the control of the microcomputer according to the rotational position of the reflecting mirror installed and fixed on the upper surface of the rotating flat plate, so that the laser beam can be irradiated accurately to a desired position of the hologram recording element.
