    摘要: An initialization apparatus that has a simplified configuration and that forms an initial hologram in an information recording medium is provided. An initialization apparatus (10) rotates an optical disk (100) and emits blue light beams (Lb1) and (Lb2) to either side of the optical disk (100) while causing a red light beam (Lr1) to follow a track formed in a reference layer (102). Thus, the initialization apparatus (10) can perform an initialization process in which a linear initial hologram IH is formed in a recording layer (101) in a spiral pattern that corresponds to the track formed in a reference layer (102). Accordingly, the initialization apparatus (10) can form a planar initial hologram layer (YH) with significantly reduced optical energy or thermal energy emitted to the optical disk (100) at one time.

    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: The present invention is applicable to a recording apparatus of a CD or DVD, a recording method thereof and a recording medium, and an object of the present invention is to clearly record a second information such as characters and figures between two recording levels in an optical disk. The second information is recorded in a predetermined area in a radius direction and a angular direction on the optical information recording medium, and further, the second information is recorded according to a change of a pit width based on a change of power of the laser beam, a change of a pit length based on an on/off control of the laser beam, or a change of depression or bulge of the pit based on a change in the vicinity of the on/off control of the laser beam. Whereby it is possible to record the second information such as a watermark pattern or a visible image, which is capable of being confirmed by seeing a disk.

    摘要: In an information recording medium from which information recorded on each pit is reproduced by an optical detection system that obtains a reproduced signal corresponding to each pit by scanning the information recording medium along pit rows by a light beam, data of high recording density can be accurately reproduced by a simple arrangement by shifting in a step-wise fashion edge positions of an information pit from a predetermined reference position in response to digital information to be recorded within a range corresponding to a predetermined shift period smaller than a transition period of a reproduced signal determined in response to a transfer characteristic of the optical detection system. Therefore, a nonlinear intersymbol interference can be reduced without emphasizing a noise component.
