能够记录大量高质量视频和音频数据的新的高密度光盘的标准化快速的发展,并且在不久的将来,在市场上期望可以通过购买获得有关新的光盘的产品。可重写的蓝光光盘(通常称作‘BD-RE’)是这些新光盘的一个例子。
如图1所示,按顺序从最内圆周开始,BD-RE盘包括钳位区,过渡区,突发切断区(BCA),引入区,数据区,和引出区。
引入区包括几个预分配的区域,比如第一保护区,永久信息&控制数据(PIC)区,第二保护区,第二信息(Info2)区,和最佳功率校准区,这些区域是其中预先记录一些初始的数据的区域,而其他的引入区,数据区,和引出区都是可重写的区域。
在PIC区中,被永久保存的有关光盘的重要信息被通过高频调制(HFM)被以抖动沟槽编码。如图2所示,通过双相调制执行抖动形式的数据编码。
在平均时间中,只读蓝光光盘(BD-ROM)的开发也随BD-RE的开发而进行着。BD-ROM盘包括内部区,钳位区,过渡区,信息区,和边缘区,如图3所示。

当光盘(BD-ROM盘)被装入光盘再现装置中时,光盘再现装置首先检测记录在PIC区中的复制保护信息(CPI),如果主要数据被加密,则使用复制保护信息(CPI)解密记录在数据区中的主要数据。
如果当装置检测解密该加密的数据需要的复制保护信息(CPI)时出现错误,即使没有数据读取错误,BD-ROM光盘的内容不能被解码。

具体实施方式
为了更充分明白本发明,将结合附图描述它的优选实施例。
根据本发明的BD-RE光盘具有的光盘结构包括内部区,钳位区,过渡区,信息区,和边缘区,如图3所示。
在信息区中分配的数据区存储诸如电影的动画内容。如图4所示,在数据区中分配的PIC区存储光盘信息,它是有关光盘的一般信息,并且还存储复制保护信息(CPI),它是解密以加密方式记录在数据区中的内容所需的。在BD-ROM光盘的情况下,通过在BD-ROM光盘的表面形成预置凹坑来进行数据记录。
存储在PIC区中的光盘信息和CPI被记录成直线凹坑,或抖动凹坑,或者部分抖动凹坑和部分直线凹坑。
存储在PIC区中的CPI是用于加密记录在数据区中的主要数据的密钥值,其被在非PIC区的区域中拷贝至少一次。
图5显示了一个例子,其中CPI被另外地写在非PIC区的区域中。
在图5中,在引入区的保留区域中和在引出区的保留区域中发现拷贝的CPI。在图5中,在这些区域中拷贝光盘信息以及CPI。
CPI可以只在引入区被拷贝至少一次,只在引出区被拷贝至少一次,或在引入区和引出区中被拷贝至少一次。
其中拷贝CPI的BD-ROM上的区域可以通过BD-ROM标准规定或可以基于制造商改变。在后者的情况下,有关每个拷贝CPI的位置的信息被包括在光盘信息表中。
图6显示了根据本发明的光盘信息表的结构。光盘信息表包括光盘上的各种类型的信息,包括光盘信息标识符,光盘大小/版本,和光盘结构。此外,光盘信息表包括有关保留字段中各个拷贝的CPI位置(CPI_位置)上的信息。
位置信息(CPI_位置)的尺寸与拷贝的CPI的数量成比例。如果有关每个拷贝的CPI的位置的信息被分配4字节且具有N个拷贝的CPI,位置信息(CPI_位置)的大小是4xN字节。
在其中在引入区和/或引出区中连同CPI拷贝盘信息的情况下,也拷贝有关各个CPI位置的信息。
图7示例了光盘再现装置的简要框图,其中可以有益的具体表现本发明。该装置包括光拾取器11,其用于从BD-ROM光盘中读取光信息;VDP(视频光盘播放)***12,其用于信号处理和伺服控制;和D/A变换器13,通过图8示例的下列过程,该装置使用复制保护信息解密记录在BD-ROM光盘上的内容并输出A/V信号。
如果具有在其上存储的复制保护信息的BD-ROM盘被***装置中(S10),VDP***12旋转BD-ROM和控制光拾取器11搜索BD-ROM的PIC区以获得CPI和光盘信息(S11)。
如果当读取CPI时出现错误(S12),VDP***12检查在光盘信息中是否具有错误(S13)。如果没有发现错误(S13-1),VDP***12读取记录在光盘信息中的有关拷贝的CPI位置(CPI_位置)的信息,并接着通过移动光拾取器11到其中写入拷贝的CPI的位置来读取CPI(S15)。如果再次出现读取错误,VDP***12移动光拾取器11到其中写入拷贝的CPI的下一个位置,并读取其中记录的CPI(S16)。
如果从PIC区中读取的盘信息具有错误(S13-1),光盘再现装置读取有关CPI位置的信息和/或存储在装置的预定位置中的光盘信息(S20)并通过移动光拾取器11到该位置来读取CPI(S21)。
如果CPI检测正常,VDP***12移动光拾取器11到数据区,从那里开始再现加密的内容和使用CPI解密再现的内容(S17)。而且VDP***12解码解密的内容并最后输出A/V信号(S18)。
记录和再现用于记录介质的复制保护信息的所述方法允许即使当由于划痕,手指印等不能从PIC区中读取复制保护信息时,正常地再现记录在记录介质上的加密数据。
尽管对于有限的实施例公开了本发明,但作为普通技术人员来说应该理解,受益于本公开,可以作出许多修改和变化。本发明意在覆盖落入本发明精神和范围内的所有这样的修改和变化。
