    • PROBLEM TO BE SOLVED: To provide an information recording/reproducing method and an information recording/reproducing device for simultaneously recording the classification information of a recording medium of a recording destination when contents are recorded and processed, and detecting the illegal copy by detecting the above information with the reproducing device, and also to provide an information recording medium. SOLUTION: The information recording method is constituted so that the information to be recorded is made into a block and an error correcting code is added thereto to produce an ECC block. A plurality of kinds of synchronizing signals SY differently aligned (as shown in the figure) in accordance with the classification of the information recording medium D or synchronizing signals SY having signal patterns according to the classification are added with specified intervals to the produced ECC block, and a recording signal based on this ECC block is recorded on the information recording medium. Since the medium is detected to be the recording medium by the alignment of the synchronizing signals at the reproduction even though the information of a ROM system is illegally copied entirely, the countermeasure such as the stop of information reproduction can be taken.

    • 要解决的问题:提供一种信息记录/再现方法和信息记录/再现装置,用于在记录和处理内容时同时记录记录目的地的记录介质的分类信息,并且通过以下方式检测非法拷贝: 利用再现装置检测上述信息,并且还提供信息记录介质。 解决方案:信息记录方法被构造成使得要记录的信息被制成块并且将纠错码添加到其中以产生ECC块。 根据信息记录介质D的分类或具有根据分类的信号图案的同步信号SY的不同对准的多种同步信号SY(如图所示)以指定的间隔加到所产生的ECC块, 并且基于该ECC块的记录信号被记录在信息记录介质上。 由于即使ROM系统的信息被完全非法复制,通过再现中的同步信号的对准来将介质检测为记录介质,因此可以采取诸如停止信息再现的对策。 版权所有(C)2004,JPO&NCIPI
