    • According to the present invention, there is provided an optical disc player adapted to record a unique ID on a read-only optical disc and positively read the unique ID from the optical disc. The optical disc (1) played with this player has a specific physical cluster in which the unique ID is to be recorded. The optical disc (1) used herein is normally molded by a molding machine using a molding die. Thereafter, a unique ID is generated for each of the optical discs (1), and high-power laser light is irradiated to a specific land in the specific physical cluster correspondingly to the bit value of the unique ID to transit the land to a pit. The physical cluster has provided therein a first area where each bit in the unique ID is recorded by the lasering in case the bit value is 0 and a second area where each bit in the unique ID is recorded by the lasering in case the bit value is 1. At the time of playback, the number of errors in the first area is compared with that in the second area to determine the value of each bit in the unique ID.
    • 根据本发明,提供了一种适于在唯一光盘上记录唯一ID并且从该光盘中正确读取唯一ID的光盘播放器。 用该播放器播放的光盘(1)具有要记录唯一ID的特定物理群集。 本文使用的光盘(1)通常由使用成型模的成型机成型。 此后,为每个光盘(1)生成唯一的ID,并且高功率激光对应于唯一ID的位值照射到特定物理簇中的特定区域,以将土地转移到坑 。 物理簇在其中提供了第一区域,其中在位值为0的情况下,通过激光记录唯一ID中的每个位,并且在比特值为0的情况下通过激光记录唯一ID中的每个比特的第二区域 在回放时,将第一区域中的错误数量与第二区域中的错误数量进行比较,以确定唯一ID中每个位的值。

    • An optical disc recording device includes: an optical disc device to record optical recording data onto an optical disc; a recording data assigning unit to divide a recording region on the optical disc into multiple divisions, part as a data region, assign optical recording data thereto; a redundancy data calculating unit to calculate redundancy data for restoring recorded data; a redundancy data assigning unit to take divided regions other than the data region as a redundancy region, and assign the corresponding redundancy data thereto; a recording/playing device having a recording capacity greater than the data region; and a recording control unit configured to record optical recording data in the data region and also at least a part thereof in the recording/playing device, cause the recording/playing device to play the optical recording data recorded therein at the time of calculating redundancy data, and record calculated redundancy data in the redundancy region.
    • 光盘记录装置包括:光盘装置,用于将光记录数据记录在光盘上; 记录数据分配单元,用于将光盘上的记录区域划分为多个分区,作为数据区域的一部分,向其分配光学记录数据; 冗余数据计算单元,用于计算恢复记录数据的冗余数据; 冗余数据分配单元,将除了数据区域之外的分割区域作为冗余区域,并将相应的冗余数据分配给冗余数据; 具有大于数据区的记录容量的记录/播放装置; 以及记录控制单元,被配置为将数据区域中的光学记录数据及其至少一部分记录在记录/播放装置中,使记录/播放装置在计算冗余数据时播放记录在其中的光学记录数据 并记录冗余区域中的计算冗余数据。
