    摘要: A recording medium including a plurality of recording layers, including: an optional first recording layer on which a light spot at a diffraction limit is formed; and a second recording layer on which a mark string pattern is formed, said second recording layer being different from said first recording layer, wherein when said mark string pattern is formed on a light receiving plane, while information of said first recording layer is reproduced, assuming that an optical distance between said first and second recording layers is dm, an optical distance d between optional two recording layers among a plurality of said recording layers is different from said dm.

    摘要: An information recording medium has a thin-film recording layer and a reflective layer that reflects a laser beam. The recording layer can be composed of an inorganic substance whose optical constant changes when exposed to a laser beam due to the change of its atomic arrangement. The recording layer can also be of an organic substance that deforms when exposed to a laser beam. The medium reflectivity, with respect to the reproduction laser beam exposure from the substrate side, is at least 65 percent on either of the recorded and unrecorded marks, and not more than 45 percent from the other of the recorded and unrecorded marks. In addition, the reflective-layer reflectivity, with respect to the reproduction laser beam, is at least 85 percent. The information recording medium additionally features excellent recording, erasing, and reproduction characteristics, with low recording power and high recording sensitivity during recording, and can even be read by a CD drive or the like.
