Description

多层记录载体和扫描该载体的装置
本发明涉及一种记录载体。每个信息层可包括与其它信息层相互独立的信息。信息层可以互相相连或由一个隔离层互相分隔开。本发明还涉及用于扫描这样的记录载体的扫描装置。在扫描期间，信息可被写入、读出或清除。
上述类型的记录载体可从欧洲专利申请案EP 0426 409 A2中获知。该已知记录载体是一种光盘，其包括在厚度方向上排列的多个记录层。每一记录层包括存储了记录层地址的识别部分，而识别部分属于该记录层。用于数据生成的数据记录的光束可以聚焦到一个记录层上。为了寻找某一特定的记录层，光束的聚焦位置在包括了最多的所有记录层的范围上变动。在每次聚焦位置经过一个记录层时产生了诸如零交点的聚焦错误信号。通过计算对应于某一参考层的零交点数目，当零交点的数目等于要求层的序或排列号时，找出具有对应于参考层的序号或排列号的要求层。
记录层的总数只能通过计算在整个范围上改变聚焦位置时的零交点的总数来得到；这需要独特的电路，例如零交点检测装置和计算装置。再者，所得结果易有差错，理由在于其取决于某一测量结果。
欧洲专利申请案EP 0 517 490 A2叙述了一种具有第一和第二数据表面的记录载体，第一数据表面具有关于表面数的报头信息。然而，为了确定某一特定表面，一种利用检测差错信号的装置将会用来计算表面数；这方法证实是费时的。
然而，本发明的目的是以一种更方便、更快捷的方式来寻求信息层的号码。根据本发明的第一方面，根据本发明的记录载体是特别在于如权要求1特征部分所述。
采用该信息，扫描装置通过只读出一层控制块便会立即知道所在的信息层号码。
按照本发明的记录载体的具体实施例的特点在于，信息块在不同层的平面中基本上具有相同的物理位置。接续的信息块可通过把扫描头在信息层平面上移动一个相当小的距离到下一个信息层的方法很快地一个接一个地被读出。
在按照本发明的记录载体的特定实施例中，至少一个信息块包括具有关于存储在该层中的用户信息的全部指示的一个子信息块。有了该信息，可以决定，要被读出的信息是存储在哪一个信息层中，随后，在该层上的控制信息块可被读出，以决定在所指示的层上的信息的位置。
本发明也涉及用于扫描按照本发明的记录载体的扫描装置。按照本发明，该装置包括用于将辐射波束聚焦到信息层上的单个光学扫描装置，该扫描装置包括
-用于产生辐射波束的辐射源，
-用于将辐射波束聚焦到一聚焦点的透镜系统，
-用于控制透镜系统的伺服装置，从而对在信息层上的辐射波束的聚焦点进行定位，
-将反射的辐射变换成电信号的检测装置，以及
-用于控制伺服装置的控制装置，其特征在于控制装置适合于控制伺服装置，以定位信息层上的聚焦点，从而通过读取包括记录载体中的信息层数目和信息层序号的指示的控制信息块来确定信息层的总数和信息层的序号。
所以，信息层的号码以一种容易的方式被确定。
本发明的这些和其它方面将参照以后所描述的实施例加以阐述，并成为显而易见。
在附图中：
图1显示了按照本发明的具有两个信息层的记录载体，
图2显示了记录载体和扫描装置，
图3显示了两个上部接连的信息层的信息区，
图4显示了控制信息块的划分，以及
图5显示了用于读记录载体的流程图。
图1显示了圆盘状记录载体1。正视图显示了记录载体的一个信息层，其信息区2由圆周形内边缘3和圆周形外边缘4围成。信息可以例如，以信息层中的圆周的或螺旋形轨道被存储，其中信息从信息区的内边缘往外边缘顺序地排列，或相反。信息可被分成，例如，扇形区，其中扇形区的顺序号从内边缘到外边缘逐渐增加。
图2是记录载体和用于光学扫描存储在记录载体中的信息的扫描装置10的扫描头的截面图。记录载体1具有透明基片5，装有第一信息层6和与之平行的第二信息层8，其间由透明的隔离层7分隔开。虽然在记录载体的本实施例中只显示了两个信息层，但是信息层数目可以大于2。隔离层可以被省略，这样第一和第二信息层相重合。藉助于在这种情况下以不同方式把信息存储在第一和第二层中。在第一和第二层中的信息在读取时可被区分开。在第一层中的信息可以，例如，以相位结构被存储，而在第二信息层中的信息以磁化强度结构被存储。也可能在区域内存储两种类型的信息，它们必须以不同的波长被读出。
扫描装置10包括辐射源11，例如，产生辐射波束12的二极管激光器。辐射波束通过波束分路器13，例如一块半透明板，和一个透镜系统14，例如一个物镜，被形成为一个聚焦点15。藉助于沿物镜的光轴移动该物镜14，如以箭头16所表示的，可使聚焦点位于任何的想要的信息层。由于第一信息层6是部分透过式的，辐射波束可通过该层而被聚焦在第二信息层8上。藉助于绕其中心旋转记录载体，以及在信息层面上沿垂直于轨道的方向移动聚焦点，信息层的全部信息区2可被聚焦点扫描。被信息层反射的辐射由存储的信息调制成，例如强度或极化方向。所反射的辐射被物镜14和波束分路器13引导到检测系统17，它把入射的辐射变换成一个或多个电信号。其中的一个信号，信息信号，具有与所反射的辐射的调制有关的调制，因此，该信号代表了已被读出的信息。其它的电信号表示对于被读的轨道的聚焦点15的位置。这后面的信号被加到伺服系统18，它控制物镜14的位置，因此就控制了在信息层平面上的聚焦点15的位置，且以这样的方式垂直于以使聚焦点跟随着要被扫描的信息层平面上的想要的轨道。
图3以图形显示了具有直线20形式的信息层6的信息区2，它从内边缘3扩展到外边缘4。所显示的在其上面的线21代表了信息层8的信息区2’，它从内边缘3’扩展到外边缘4’。线20和21的上面的部分也是在记录载体1的上面。在信息区2的起始端，也就是在线20的内边缘3的边侧处，保留了控制区22，用来存储控制信息。用户信息被存储在位于控制区22和外边缘4之间的地区。用户信息被存储的方向以箭头23表示。按照本发明，位于控制区22上面的控制区24也被保留在信息区2’中。用户信息被存储在外边缘4’和控制区24之间的地区，信息是沿着以箭头25表示的与以箭头23表示的方向相反的方向顺序地排列。相反的排列方向可藉助于提供以向外扩展的螺旋线轨道的信息层6以及提供以向内扩展的螺旋线轨道的信息层8来实现。这样用户信息可藉从内边缘3到外边缘4地扫描信息层6的信息区2，把聚焦点从信息层6移位到信息层8，以及从外边缘4’到内边缘3’扫描信息区2’等来被读出。在信息层6和8中以相反方向排序的信息可很快地一个接一个地被读出，因为比起聚焦点从一个信息层的外边缘移动到另一个信息层的内边缘来说，聚焦点可相当快地从一个信息层移动到另一个信息层。在原先的情况下，如果该记录载体是恒定的线性速度类型的话，还应当考虑为改变记录载体的旋转速度所需要的时间。
控制区22包括各个不同的带有控制信息的信息块，也被称为控制块，每个具有相同的内容。三个这样的控制块26、27、28示于图3的实施例。该控制块被存储三次，以便如果一个控制块的内容由于它包含的错误比起通过可能存在的纠错电路和存储在记录载体上的纠错码可被恢复的错误更多而不能被读出，就能读另两个控制信息块之一的内容。按照本发明位于控制区22的上面的控制区24也包括三个控制信息块29、30和31。带有用于信息层8的控制信息，在一个信息块中的信息沿着箭头25的方向被顺序地排列。
图4以图形显示了用于第一信息层6的控制信息块26的划分。该信息块26包括带有关于记录载体作为一个整体的信息的第一子信息块32。信息可包括记录载体的类型指示，记录载体中信息层的数目和用户信息的信息块的数目的指示，用于写和读的辐射波束的参数，关于所存储的信息的密码的信息，存储在每一层中的用户信息的总的指示的目录表，有关一组记录载体的数据，其中的一部分就是该载体，以及出版者和制造商的指示。
控制信息块26的第二子信息块33包括有关该信息块被写入的那个信息层的信息。除了层的顺序号的指示外，它还有该信息层上用户信息的信息块数目和用户信息的类型的指示。
控制信息块26的第三子信息块34包括控制信息块被写入的那个信息层的目录表。目录表表示了有关的用户信息的每个信息块的起始的和最终的地址，在每个信息块中用户信息的简短指示或具有这样的指示的地址。
控制信息块26的第四子信息块35包括重新分配表，其中参考地址是为信息层的不能写入的和不能读出的扇形区而提及的。第四子信息块只是在能写入的媒体中才是需要的。在第一信息层6上的控制信息块26包括所有的所述子信息块，而在其它信息层上的控制信息块包括第二、第三和可能的第四子信息块。其它的信息层也可包括第一子信息块。
图2所示的扫描装置10适合于在读出用户信息之前顺序地读出控制信息的信息块。为此，扫描装置包括用于使聚焦点，例如以上面提到的伺服系统的形式跟踪轨道，以及把聚焦点从一个信息层移到另一个信息层的装置。以上提到的聚焦点的位移可通过伺服系统来实现，它保持聚焦点在信息层上。
该装置也包括控制单元36，特别是控制伺服系统18。控制单元按照控制程序进行工作，它以这样的方式控制扫描装置，即在正确读出信息层6中的控制信息块以后该层中的用户信息先不被读出，而是把聚焦点移向信息层8，在其上读出用于该层的控制信息块。这样一个控制程序的流程图示于图4，用于读出按照本发明的记录载体上的用户信息的信息块。在第一步骤37中，通过伺服系统18，把聚焦点15对准在第一信息层6上。第二步骤38，读出在该层上的控制信息块26的信息。信息包括信息层总数N和即刻的被读信息层的序号i。如果i≠N，即还没有读过所有的信息层，则在步骤39把聚焦点对准下一个信息层。且有关的控制信息块被读出。如果i＝N，即所有控制信息已被读过。对于已被读过的所有控制信息块中的信息，在步骤40确定哪个信息层包括要被读出的用户信息的第一信息块。在步骤41，聚焦点被放置到适当的信息层上，在步骤42，聚焦点被放在该信息层的用户信息的信息块位置上，此后信息块中的信息被读出。如果带有用户信息的更多信息块必须被读出时，则控制程序返回到步骤40，以便从已被读过的控制信息确定下一个信息块的位置。
控制程序也可被用来写入和消除记录载体中的信息。在写入期间，在步骤40确定用户信息的信息块可被写的地方和哪一个信息层上。当在写入所述区期间由于记录载体中的缺陷，必须重新分配以后的扇形区时，可以把适当的地址记在所写的信息层的控制信息块的重新分配表中。在消除期间，在步骤40确定在适当的区被消除后，被消除的信息可被写入的地方和哪一个信息层上。
在许多扫描装置中，聚焦点是通过构成伺服系统18的一部分的两级移位系统沿记录载体的半径方向进行移动的。第一级是滑动的比较慢和大的位移，而第二级是物镜14沿径向的比较小和快的位移。对快速读出控制信息块，信息块以及宁可是控制区的径向尺寸小于由物镜造成的聚焦点15的最大径向位移。此最大位移通常是100μm的数量级。以控制区的给定半径。轨道间的距离以及记录载体1的轨道上的信息密度，这就产生大约每个控制信息1兆字节的容量。如果所有信息层的控制信息被存储在信息层6的1兆字节的单个信息块中，则很明显，当使用很多层时就会产生容纳空间问题。本发明通过把和信息层有关的控制信息放置在该信息层本身的信息块而解决了这个问题。其它信息层的划分，因而也就是用于用户信息的区域尺寸可以和信息层的数目无关。
显然，所述的存储信息的模式并不限于以前面所述的方式提供的控制信息块的记录载体，也不限于只适合于通过单个扫描头进行读数的记录载体。
也很显然，本发明的使用并不限于圆盘状的记录载体，它也适合于例如矩形的记录载体如存储卡。虽然本发明是参照光学记录载体加以说明的，但很显然，本发明可替换地被使用于可通过单个扫描头读取的任何类型的多层记录载体。
