    摘要： An optical recording medium which has an enhanced appearance or an enhanced design performance while computer data are recorded and a reproduction apparatus and method in which the optical recording medium is used are disclosed. When computer data are recorded on the optical recording medium on which recording data are recorded as interference fringes formed through interference of object light of images with reference light, related information of the recording data is recorded in a state wherein it can be recognized through the visual sense of the user.

    摘要： A recording medium records therein image data for distributing contents as element holograms with interference fringes generated by interference between an object beam representing the image data and a reference beam. The image data to be distributed which are recorded as the element holograms in the recording medium are reproduced by applying reference beams to the recording medium.

    摘要： An equalizer used for an optical reproducing apparatus performs an optimal equalizing operation in accordance with the spatial frequency without needing an electrical equalizer. The optical reproducing apparatus reproduces the reproducing data in the following manner. A detector is provided for receiving reflected light from a disc. The detector is divided into a plurality of light receiving areas by a line perpendicular to the light receiving direction corresponding to the disc track direction. Then, calculations are made on the outputs from the respective light receiving areas to specifically correct the spatial frequency characteristics. The calculated signal is then decoded.

    摘要： A magneto-optical disk which reproduces information with an optical pickup head which uses an electromagnetic force as the driving force is provided. Other areas than at least the recording track are magnetized uniformly in a direction of canceling the influence of external magnetic field applied by the optical pickup head or a recording pattern having a frequency higher than modulation transfer function (MTF) of the optical pickup head is recorded to the other areas than at least the recording track. Read signals SP12 and SP14 from the magneto-optical disk are low in bit error rate.

    摘要： Reproduction reference light is irradiated on a hologram recording medium on which imaged digital data are recorded as a plurality of element holograms in the form of interference fringes obtained by interference between object light of the digital data and recording reference light. Then, a reproduction image obtained from the hologram recording medium by the irradiation of the reproduction reference light is detected. Then, readout data are produced based on the detected reproduction image. Thereafter, it is discriminated whether or not the readout data should be stored into a memory, and the readout data are stored into the memory in response to a result of the discrimination. Where a predetermined amount or more of the data is accumulated in the memory, reproduction data are produced from the readout data accumulated in the memory and then reproduced.
