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： A magneto-optical recording/reproducing method is disclosed which causes a laser beam to be emitted to a disc recording medium having information recorded thereon earlier by magnetic field modulation, the laser beam causing the disc recording medium to develop a temperature distribution such as to generate a driving force for moving a domain wall of a magnetic domain in the medium so that the magnetic domain smaller in diameter than a spot of the laser beam is expanded sufficiently to let information recorded in the domain be detected. The method comprises the steps of: recording information to the disc recording medium while rotating the medium in a first rotating direction; and reproducing the information that was recorded to the disc recording medium in the recording step while rotating the medium in a second rotating direction reverse to the first rotating direction.
