摘要： According to one embodiment, an optical information recording apparatus includes a spatial light modulator, an optical mechanism, a driving module, and a controller. The spatial light modulator converts an irradiation beam emitted from a light source to plural partial information beams that carry information by causing the irradiation beam to pass through plural modulation areas. The optical mechanism collects the partial information beams onto an optical information recording medium and applies a reference beam onto the recording medium such that the reference beam and the partial information beams intersect with each other on an information recording layer. The driving module drives the recording medium or the optical mechanism. The controller performs angle multiplex recording of information on the information recording layer by controlling the driving module and causing the light source to emit the irradiation beam while switchingly supplying the modulation areas with the information.

摘要： In a device for detecting a focus error in controlling a position in an optical axis, a laser beam is split into first and second beam components, and one of the first and second beam components is diverged or converged. Then, the first and second beam components are superposed on each other, providing a single laser beam. The single laser beam is applied to an optical data-recording medium through an objective lens. The first laser beam component is focused on a first focusing point that is set at one side of the pinhole. The second beam component is focused on a second focusing point that is set at the other side of the pinhole.

摘要： 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.
