    • PROBLEM TO BE SOLVED: To solve the problem that trace length has to be further secured long to make it difficult to acquire data in search, or the like in order to determine the right or wrong of acquired data because the trace length for acquiring one piece of information becomes long when the number of bits of the entire land pre-pit block is reduced.
      SOLUTION: In the land pre-pit block, identification information is arranged at bit positions of "9" to "11" being almost the center of pre-pit data block. An optical disk device can recognize information reproduced between a pre-pit synchronizing signal and the identification information as first record information and recognize information reproduced between the identification information and the next pre-pit synchronizing signal as second record information. Since the identification information is shared to identify the first record information and the second record information, the identification information is 13 bits being the same as the trace length for acquiring one piece of record information, and in addition, the number of bits of the entire land pre-pit block can be reduced than in the conventional configuration.

    • 要解决的问题为了解决长时间要进一步确保跟踪长度以使得难以获取搜索中的数据等的问题,以便确定获取的数据的正确或错误,因为跟踪长度为 当整个陆地预制块块的位数减少时,获取一条信息变长。 解决方案:在陆地预制凹坑块中,识别信息被布置在几乎位于预凹坑数据块的中心的“9”到“11”的比特位置。 光盘装置可以将在预凹陷同步信号和识别信息之间再现的信息识别为第一记录信息,并将识别信息和下一个预凹陷同步信号之间再现的信息识别为第二记录信息。 由于识别信息被共享以识别第一记录信息和第二记录信息,所以识别信息是与用于获取一条记录信息的记录长度相同的13位,另外,整个数据的位数 与常规配置相比,可以减少地面预制块。 版权所有(C)2009,JPO&INPIT
