    摘要: [Object] To enable stable void recording to be performed with lower power than in a case where a conventional void (hole) recording method is adopted.
    [Solving Means] Provided is an optical recording medium including a recording layer in which a plurality of boundary surfaces of resin layers are formed, and intervals of the boundary surfaces are set to be equal to or smaller than a focal depth of recording light. A recording sensitivity of hole marks is enhanced at the boundary surfaces of the resin layers. Therefore, by providing the recording layer in which the boundary surfaces are provided at intervals equal to or smaller than the focal depth of recording light as described above, that is, the recording layer is practically filled with the boundary surfaces, the hole mark recording sensitivity of the recording layer can be enhanced as a whole. Accordingly, it becomes possible to suppress laser power requisite for recording to be smaller than that of the conventional art and solve the problems of the conventional void recording method. As a result, realizability of a large-capacity recording medium as a bulk-type recording medium can be additionally enhanced.

    摘要: The present invention makes it possible to use an optical pickup in common with conventional optical disks. In a three-dimensional mark recording layer (111v) of a voluminal medium (100v), information is recorded by forming a three-dimensional record mark (RM) in the vicinity of the focus (Fb) of a blue light beam (Lb) according to the blue light beam (Lb) that is concentrated and has a light intensity equal to or larger than a predetermined intensity. The information is reproduced from the three-dimensional mark recording layer (111v) on the basis of a reproducing blue light beam (Lbr) deriving from irradiation of the blue light beam (Lb). A servo layer (114v) of the voluminal medium (100v) reflects at least part of the red light beam (Lr) which is irradiated in order to square the position of the blue light beam (Lb) in the three-dimensional mark recording layer (111v) with an arbitrary target mark position and whose wavelength is different from that of the blue light beam (Lb). The servo layer (114v) is separated by approximately 0.6 mm in the light-axis (Lx) direction of the red light beam (Lr) from the incident surface (100vA) to which the red light beam (Lr) is routed.

    摘要: A substrate is deformed into a raised shape by irradiating an optical disc recording medium with a laser beam at a prescribed laser power. As the substrate is deformed into the raised shape, a reflecting film laminated on the substrate is also deformed into the raised shape, and a reproduction signal level equivalent to that of a land portion can be obtained at a pit portion by the embodiment of the raised deformation. A reproduction signal level equivalent to that of the pit portion can be obtained at the land. At this time, since the raised deformation embodiment can be controlled by the power of the laser beam applied, the pit can be made into land and the land can be made into pit by setting the laser power. Thus, recording data can be rewritten in the optical disc recording medium wherein data is recorded by the combination of the pits and lands formed on the substrate.
