    • PROBLEM TO BE SOLVED: To improve the possibility of a negative-type micro-hologram system by dispensing with initialization processing needed in a conventional negative type micro-hologram system, thereby solving the problem relating to the initialization processing. SOLUTION: An optical recording medium is obtained by alternately laminating: recording layers which are transparent and each constituted of a diffraction grating having a predetermined grating pitch by alternately laminating first layers and second layers slightly different in refractive index from each other; and intermediate layers which are transparent and each larger in thickness than each recording layer. Since the recording layers (diffraction gratings) needed to form an erasure mark are previously formed, the initialization processing is no longer required. As a result of this, it is possible to markedly shorten a period needed until the start of recording and to solve the problem of the conventional negative-type micro-hologram system relating to the power of initialization light and the recording sensitivity of a bulk layer, so as to improve the possibility of the multilayer recording medium (large capacity recording medium) by the negative-type micro-hologram system.

    • 要解决的问题:为了通过分配常规负型微全息图系统中所需的初始化处理来提高负型微全息图系统的可能性,从而解决与初始化处理有关的问题。 解决方案:光学记录介质通过交替层叠:透明的记录层,并且每个由具有预定光栅间距的衍射光栅构成,通过交替层叠彼此稍微不同折射率的第一层和第二层; 和中间层,其是透明的并且每个比每个记录层的厚度都大。 由于预先形成了形成擦除标记所需的记录层(衍射光栅),所以不再需要初始化处理。 作为其结果,可以显着缩短开始记录所需的时间,并且解决与初始化光的功率和主体层的记录灵敏度有关的常规负型微全息图系统的问题 ,以便通过负型微全息图系统提高多层记录介质(大容量记录介质)的可能性。 版权所有(C)2011,JPO&INPIT
