    摘要： An optical information recording medium of the present invention, a reproduction method using the optical information recording medium, and an optical information processing device using the optical information recording medium, each of which optically reproduces recorded information by irradiating a light beam, include: a substrate on which a bumpy pit and/or groove corresponding to the recorded information or a recording layer is formed; and a temperature responsive layer whose optical property (transmissivity) in a wavelength of the light beam varies in response to temperature rise caused by irradiation of the light beam. The optical information recording medium can surely reproduce information, which has been recorded in a high density manner, with high accuracy.

    摘要： This invention allows super-resolution reproduction with which a better bER value is attainable, when information is recorded by a random pattern including a mark length not longer than a resolution limit, by use of a highly versatile signal decoding method.Information is recorded as marks and spaces coded by RLL(1,7) modulation, which each of the marks and spaces have one of, a plurality of lengths, and 2T marks and 2T spaces of the marks and spaces being formed are shorter than 0.12 μm. An information recording layer (20) includes a reproduction film (21) and a reflective film (22) which are provided in this order from a side from which reproducing light is incident, which reproduction film is made of (i) zinc oxide, (ii) strontium titanate, (iii) titanium oxide, (iv) cerium oxide, or (v) a material including at least one of the (i) through (iv), and which reflective film is made of tantalum or titanium.

    摘要： In an optical information storage medium reproduction apparatus (10) for reproducing an optical information storage medium including a plurality of information recording layers each including a recording mark having a length shorter than an optical system resolution limit, reproduction laser power for reading an information recording layer closest to a reproduction-laser-incident surface of the optical information storage medium is set to be lower than reproduction laser power for reading an information recording layer farthest from the reproduction-laser-incident surface but not lower than minimum reproduction laser power that satisfies a reproduction signal characteristic that the optical information storage medium reproduction apparatus (10) requires. With the arrangement, it is possible to prevent that the information recording layer closest to the reproduction-laser-incident surface is irradiated wrongly with reproduction laser having high reproduction laser power, thereby making it possible to obtain successful reproduction quality. That is, it is possible to realize the optical information storage medium reproduction apparatus (10) that can set optimum reproduction laser power and perform stable super resolution reproduction.
