摘要： A need to effectively record data of various sizes on a large-capacity holographic memory capable of high-speed recording is achieved, for example, by curing a first part of the holographic recording which is able to be multiplex-recorded in one or more units of a predetermined volume, and by not recording/curing a second part which is not able to be multiplex-recorded in a predetermined volume at a timing when the first recording part is cured. Also the above need can be achieved by, another example, by adding dummy data to the second part. Alternatively, the second part can be recorded on another track, in which it is possible to record in different units, e.g. by bit recording in a track that utilizes a DVD recording format. According to the present examples, we can record data of various sizes on the holographic memory effectively while performing large-capacity and high-speed holographic recording.
摘要翻译：可以在能够高速记录的大容量全息存储器上有效地记录各种尺寸的数据的需要，例如通过固化能够被多路复用记录在一个或多个单元中的第一部分全息记录并且通过在第一记录部件被固化的时刻不记录/固化不能被多路复用记录在预定体积中的第二部分。另外，通过向第二部分添加虚拟数据也可以实现上述需要。或者，第二部分可以记录在另一个轨道上，其中可以以不同的单位记录，例如，通过利用DVD记录格式的轨道中的比特记录。根据本实施例，在进行大容量高速全息记录的同时，可以有效地在全息存储器上记录各种尺寸的数据。

摘要： Each layer includes a data recording area and a test writing area divided into a plurality of small areas, wherein the small areas of the test writing area are recorded in advance so that other each layer can make a combination of recorded and unrecorded states with respect to the small area, where OPC is carried out, in a layer where OPC is carried out. Moreover, OPC is carried out to each small area, where a combination of recorded/unrecorded states of other each layer differs from each other, to thereby calculate, as the optimum power, an average value of the result of each OPC or a central value of the dispersion thereof.
摘要翻译：每个层包括数据记录区域和分成多个小区域的测试写入区域，其中预先记录测试写入区域的小区域，使得其他每层可以相对于记录区域和未记录状态组合在执行OPC的层中执行OPC的小区域。此外，对每个小区域进行OPC，其中每层的记录/未记录状态的组合彼此不同，从而计算每个OPC的结果的平均值或中心值的分散体。
