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.
摘要翻译：与使用常规的空隙（孔）记录方式的情况相比，能够以较低的功率进行稳定的空隙记录。 [解决方案]提供一种光记录介质，其包括其中形成有树脂层的多个边界面的记录层，并且边界面的间隔被设定为等于或小于记录光的焦深。在树脂层的边界面处，孔标记的记录灵敏度增强。因此，如上所述，通过设置以等于或小于记录光的焦深的间隔设置边界面的记录层，即记录层实际上被边界表面填充，孔标记记录灵敏度记录层的整体可以得到增强。因此，可以抑制记录所需的激光功率小于常规技术的激光功率，并且解决了传统的空白记录方法的问题。结果，作为大容量记录介质的大容量记录介质的可实现性可以进一步提高。

摘要： [Object] To enable stable void recording to be performed with lower power than in a case where a conventional void recording method that records hole marks (voids) in a bulk layer is adopted.[Solving Means] First laser light is irradiated onto an optical recording medium in which a plurality of resin layers are formed while the first laser light is focused on a boundary surface of the resin layers, to thus record hole marks onto the boundary surface. Since a recording sensitivity of the hole marks is enhanced at the boundary surface of the resin layers, by recording hole marks onto the boundary surface as described above, laser power requisite for recording can be suppressed as compared to the conventional art. As a result, it becomes unnecessary to use a special laser such as a short-pulse laser, and even if a CW laser (CW: Continuous Wave) is used, a recording speed does not need to be sacrificed. By compensating weak points of the conventional void recording method, realizability of a large-capacity recording medium as a bulk-type recording medium can be additionally enhanced.
摘要翻译：与采用体积层中记录孔标（空隙）的常规空隙记录方法相比，能够以较低的功率进行稳定的空隙记录。 [解决方案]第一激光照射到其上形成有多个树脂层的光记录介质上，同时第一激光聚焦在树脂层的边界面上，从而将孔标记记录到边界表面上。由于在树脂层的边界面处增加了孔标记的记录灵敏度，通过如上所述将孔标记记录到边界表面上，与传统技术相比，可以抑制用于记录的激光功率。结果，不需要使用诸如短脉冲激光器的特殊激光器，并且即使使用CW激光器（CW：Continuous Wave），也不需要牺牲记录速度。通过补偿常规空隙记录方法的弱点，可以进一步提高作为体型记录介质的大容量记录介质的可实现性。

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.
