T匿A也^^皮周期性地或者需要时进行更新。 A leather hide ^^ T can be updated periodically or as needed. 当BD-WO准备完成(例如,在用户数据区域中的数据写入操作完成、T画A装满、或者从用户收到结束命令等)时,那么,临时写入TDMA中的TDMA信息(最新版本)被转移和写入到T画A 1-4的一个或各个上。 When ready BD-WO (e.g., data in the user data area write operation is completed, T A full painting, or the like from the user end command is received), then the TDMA information temporarily written in the TDMA (Latest version) is transferred and written in one or each of a 1-4 is drawn on the T. 写入TDMA 1和2各个中的TDMA信息包括临时缺陷列表(TDFL ) 信息和临时盘定义结构(TDDS)信息。 TDMA information is written. 1 and TDMA 2 each includes a temporary defect list (the TDFL) information and temporary disc definition structure (the TDDS) information. 在一个实施例中,TDFL信息包括一个或多个TDFL (TDFL #1~TDFL #n )。 In one embodiment, TDFL information includes one or more of the TDFL (TDFL # 1 ~ TDFL #n). 各个TDFL包括一个或多个缺陷项(defect entry),缺陷项标识缺陷和在盘上对应的替换区域。 Each TDFL includes one or a plurality of defect entries (defect entry), the corresponding defect entries identifying defects and disc replacement area. 各缺陷项包括与用户数据区域的有缺陷的区域和对应的替换区域有关的位置信息。 Each defect entry includes location information regarding the replacement area corresponding to the user data area and a defective area. 例如,在BD-WO上的数据记录操作期间,如果在用户的 For example, data on the BD-WO recording during operation, if the user's

数据区域中发现有缺陷区域,那么,按照线性替换模式,写入或将要写入有缺陷区域中的数据,被写入在备用区域(例如,ISA0或OSA0) 的一部分(替换区域)中。 Defective area found in the data area, then, in accordance with the linear replacement mode, or to write data to be written in the defective area is written in a portion of the spare area (e.g., ISA0 or OSA0) of (replacement area). 然后,与有缺陷区域和替换区域及它们的关系有关的信息作为缺陷项被输入到TDFL中。 Then, a defective area and the replacement area and their relationship information is entered as a defect entry in the TDFL. 例如,该信息可以包括在盘上的有缺陷区域的第一物理扇区号、对应于有缺陷区域的替换区域(备用区域)的第一物理扇区号、和与缺陷管理的缺陷有关的其他任何数据。 For example, the information may include a first physical sector number of the defective area on the disc, a region corresponding to the defective replacement area (spare area) is a first physical sector number, and any other data related to the defect management defect . 在一个实施例中,写入在TDMA 1和2的各个中的TDDS信息包括一个或多个TDDS (TDDS #1~TDDS #n )。 In one embodiment, the TDDS information written in the TDMA 1 and 2 each comprise one or more TDDS (TDDS # 1 ~ TDDS #n). 各TDDS具有固定的容量(例如, 一个簇)并且包括与TDFL有关的位置信息,从而通过访问TDDS 能够快速地识别任何TDFL的位置。 Each TDDS has a fixed capacity (e.g., one cluster) and includes location information relating to the TDFL, the TDFL is possible to identify any location by accessing the TDDS quickly. 这一位置信息能够被写入在一个蔟的扇区Q的一部分中,并且可以包4舌一个或多个各指示出写入BD-W0 上的TDFL位置的物理扇区号,和任何与TDFL信息相关的其它信息。 This location information can be written in a portion of a sector in the Q of the nest, and the tongue 4 may be coated with one or more physical sector numbers each indicating a location of the TDFL written on the BD-W0, the TDFL information, and any other relevant information. 这里, 一个簇有32个扇区,各扇区有2048个字节。 Here, a cluster has 32 sectors each of 2048 bytes. 各TDDS还包括记录模式信息。 Each TDDS also includes recording mode information. 该记录模式信息标识BD-WO的记录模式,并且能够被写入在一个簇的扇区0的一部分中。 The recording mode information identifies a recording mode of the BD-WO and can be written in a portion of the sector 0 of the cluster. 与TDFL相关的位置信息和上面讨论的记录模式信息这里也被称为TDDS部分。 Position information and recording mode information discussed above relating to the TDFL is also referred to herein TDDS part. 这里, TDDS部分占据整个扇区0 (或者任何另外指定的位置区域)。 Here, TDDS part occupies the entire Sector 0 (or any additional specified location area). 各TDDS还包括盘使用管理信息,其标识BD-WO的记录区域的状态, 并且,能够以下列两种形式中的一种表示:轨道信息(Track-Info) 和空间位图信息(SBM)。 Each TDDS further includes disc usage management information, which identifies the state of the recording area of ​​the BD-WO, and can be expressed in one of two forms: track information (Track-Info) and space bitmap information (SBM). TDDS的这一结构将在后面通过参考图4进行更详细地讨论。 This structure of the TDDS will be discussed with reference to FIG. 4 in more detail later with. 当进行写入数据到数据区域的数据记录操作时,TDMA可以被周期性地更新,以反应任何当前发现的有缺陷的区域和对应的替换区域。 When the data recording operation for writing data into the data area, TDMA can be updated periodically to reflect any defective area and the replacement area corresponding to the currently found. 在TDMA的每一次更新以后,可以包括所有的原先的TDMA信息和最近生成的TDMA信息的TDFL和对应的TDDS,可以被写入在TDMA中。 After each updating of the TDMA, may include all previous TDMA information and the recently generated TDMA information TDFL and the TDDS corresponding, may be written in the TDMA. 在这一方面,写入在BD-WO的TDMA中的最新TDDS和TDFL将包括最新TDMA 信息。 In this regard, written in the BD-WO TDMA in the latest TDDS and TDFL will include the latest TDMA information. 然后,当BD-WO将完成时,写入在BD-WO上的最新TDDS和TDFL 被转移并写入在DMA l-4中的一个或各个中,作为最终的和最新更新的缺陷管理信息。 Then, when the BD-WO will be completed, the writing on the BD-WO latest TDDS and TDFL are transferred and written in one or each of the DMA l-4, and as a final updated latest defect management information. 图4所示为按照本发明的实施例的可重写盘的DDS结构、BD-WO的TDDS结构和BD-WO的盘管理信息记录方法的实例。 It is a rewritable disc according to an embodiment of the DDS structure of the present invention, TDDS structure of the BD-WO shown in FIG. 4 example and the disc management information recording method for the BD-WO. 如图4中所示,在通常的可重写入光盘的DDS中,仅有对应于1簇的特别小的部分的60 字节信息被用于在其中存储DDS信息。 Particularly small 60-byte information part as shown in FIG DDS in a general rewritable optical disc, corresponding to only one cluster 4 is for storing therein information DDS. DDS所有的剩余部分被全部设置为'补零(zero padding )'。 DDS is all of the remaining portions of all set to 'zero padding (zero padding)'. 相反,在BD-WO中,整个的TDDS区域被用于在那里存储TDDS信息。 In contrast, in the BD-WO, the entire TDDS area is used TDDS information stored there. 如图3和4所示,TDDS部分(包括位置信息和记录模式信息)被写入在分配作为TDDS的簇的整个的扇区0中,而扇区1-31在其中存储盘使用管理信息(Track-Info或SBM)。 3 and 4, TDDS part (including the location information and the recording mode information) are written in the four cluster assigned as the TDDS entire sector 0, and the sector 1-31 store therein the disc usage management information ( Track-Info or SBM). 在另一个实例中,盘使用管理信息能够被记录在TDDS中的最初的31个扇区(扇区Q~30)上, 并且,任何剩余的盘使用管理信息与TDDS部分一起能够被记录在TDDS 中的最后的第32个扇区(扇区31)上。 In another example, the disc usage management information can be recorded on the first 31 sectors (sector Q ~ 30) in the TDDS, and any remaining disc usage management information can be recorded together with the TDDS part in the TDDS last 32nd sector (sector 31). 按照本发明,记录模式信息标识应用在BD-WO中的多个记录模式中的一个。 According to the present invention, the recording mode information identifies a recording mode of a plurality of applications in BD-WO in one. 在这一实例中,"0000 0000"的值可以被用于表示顺序记录模式,并且"0000 0001"的值可以被用于表示随机记录模式。 In this example, the value "0000 0000" may be used to indicate a sequential recording mode, and a value of "0000 0001" may be used to indicate a random recording mode. 明显地,还可有其它的实例。 Obviously, there may be other examples. 根据本发明有关BD-WO的信息可根据需要按照技术说明规则的方法不同地确定。 It may be determined as needed according to the different technical description of the method in accordance with the rules information about the BD-WO according to the present invention. 盘使用管理信息随盘的用途不同而变化。 Different purposes varies with the disc using the disc management information. 在BD-WO中,为了精确地搜寻和检测可用的记录区域的开始点,需要盘使用管理信息,并且盘使用管理信息用于区别盘上的记录区域和未记录区域。 In the BD-WO in order to accurately searching and detecting the start point of the recording area is available, it is necessary to use the disc management information and disc management information for using the recording area on the disc and the difference between an unrecorded area. 在这一方面, 盘使用管理信息表示可用的记录区域和已记录的区域位于数据区域(例如,用户数据区域)中的位置。 In this aspect, the disc usage management information indicating a recording area and the available area in the data recorded region (e.g., user data area) in position. 如上所述,盘使用管理信息可以用轨道信息(Track-Info)或者空间位图信息(SBM)来表示。 As described above, the disc usage management information may track information (Track-Info) or the space bitmap information (an SBM) is represented. 当BD-W0以顺序记录模式记录时通常使用Track-Info。 When the BD-W0 recorded sequential recording mode is often used Track-Info. 当BD-W0以随机记录模式记录时通常使用SBM。 When the BD-W0 recorded in a random recording mode is generally used SBM. 这些记录模式可以依据存储在TDDS中的记录模式信息所识别的记录模式来确定。 These recording modes can be determined according to the recording mode information stored in the TDDS of the identified recording mode. 在传统的一次性写入光盘中,记录状态/模式信息在压缩盘系列中被表示为'轨道信息,,以及在DVD系列中被表示为'Rzone,,'片段(Fragment)'或'记录范围,。 In a conventional write-once optical disc, the recording status / mode information in a compact disc series is expressed as' track information ,, and a DVD series as shown in ',,, Rzone' fragment (Fragment) 'or' recording range . 但是,在本发明中,前面所述的关于记录状态/模式信息的各种表达方式都被称为'Track-Info,,而Track - Info相应地被理解为具有这些含义而不管它的表达方式。 However, in the present invention, the aforementioned various expressions recording status / mode information are referred to on the 'Track-Info ,, and Track - Info expression accordingly be understood as having such meaning irrespective of its . 在一个实施例中,由于在BD-WO上的轨道在顺序记录模式期间被顺序地用来记录,Track - Info识别BD-WO的记录区域(比如,用户数据区域)的开始点(位置),以及记录区域的上一个记录部分的结束点(位置)。 In one embodiment, since the tracks on the BD-WO in order during the recording mode is sequentially used for recording, Track - Info identification area recording the BD-WO (e.g., user data area) of the start point (position), and the end point of a recorded portion of the recording area (position). 这个信息就表明在BD-WO上的记录区域的下一个可用部分的开始。 This information would indicate the start of the next available portion of the recording area on the BD-WO. 位图信息利用位值如'0,和'1,来标识BD-WO上的记录区域的可用记录部分的开始点。 Bitmap information using bit values ​​such as' 0, and "1, identifies a start point of the recording area on the BD-WO is available for recording portion. 比如,如果在BD-WO上的记录区域的特定簇区域已经被记录,它就会通过给每一个最小记录单元(1簇)赋值T 来标明。 For example, if a particular cluster area of ​​the recording area on the BD-WO has been recorded, it will be designated by T assigned to each minimum recording unit (1 cluster). 如果记录区域的簇区域上没有记录的数据,那么该簇就会被 If no data is recorded on the cluster area of ​​the recording area, then the cluster will be

分配一个值'0,。 Assigned a value of '0 ,. 这样,如果SBM表示具有分配的值T的特定簇, 那么它就表明该簇已经被使用了(即,在其上已经记录数据了)。 Thus, if the SBM indicates a particular cluster has a value of T is assigned, then it indicates that that cluster has been used (i.e., in which the data has been recorded). 如果SBM表示具有值'0,的特定簇,那么它就表明该簇还没有被使用(即, 在其上还没有记录数据)。 If the SBM indicates having a value of '0, of a particular cluster, then it indicates that that cluster has not been used (i.e., on which data is not recorded yet). 显然,相反的或者其他的一些数据也可以用来标识各个区域单元譬如用户数据区域的簇的记录/未记录状态。 Obviously, the opposite, or some other data may also be used to identify clusters of each area unit such as the user data area is recorded / unrecorded state. 因此,该SBM使表示盘的记录使用状态成为可能,即使在随机记录模式中。 Thus, the SBM makes use state indicating a disc recording becomes possible, even in the random recording mode. 图12示出了根据本发明的另一个实施例的一次性写入光记录介质,如单层BD-冊,的结构。 FIG 12 shows another embodiment of the invention disposable embodiments writing optical recording medium such as a single layer BD- volumes structure. 除了TDDS部分,图12中的BD-W0结构和图3中的BD-W0结构相同,它包括TDFL的位置信息和记录模式信息, 在各个更新状态之后被更新和写入,如图12所示。 In addition TDDS part, the same as in FIG. 12 BD-W0 and the structure in FIG. 3 BD-W0 structure including position information and the TDFL recording mode information, is updated and written after each update state, as shown in FIG. 12 . 在这种情况下,盘使用管理信息(Track-Irifo或者SBM)被存储在一个簇的扇区G - 30 中,以及TDDS部分存储在一个簇的扇区31中。 In this case, the disc usage management information (Track-Irifo or SBM) is stored in a storage cluster sector G - 30, and in TDDS part is stored in Sector 31 of the one cluster. TDDS部分占据整个扇区31。 TDDS part occupies the entire Sector 31. 在另一个实例中,TDDS部分可以被存储在一个簇的整个扇区0 中,并且Track-Info或者SBM可以存储在一个簇的扇区1 - 31中。 In another example, the TDDS part may be stored in the entire Sector 0 of one cluster, and the Track-Info or SBM may be stored in a sector cluster 1-- 31. 图5示出了根据本发明的一个实施例的双层BD-WO的结构。 FIG. 5 shows the structure of two-layer BD-WO according to an embodiment of the present invention. 在图5 中示出的该双层BD-WO的结构和各区域的指定是为了描述方便和理解的示例,并不限制本发明的范围。 Structure and the regions of the bilayer designated the BD-WO shown in FIG. 5 is an example for description convenience and understanding, and do not limit the scope of the invention. 参照图5, BD-WO包括两个记录层。 Referring to FIG. 5, BD-WO includes two recording layers. 第一记录层(层0或者L0 )包括导入区域,数据区域40a,和外部区区域Outer Zone 0。 A first recording layer (Layer 0 or L0) includes a lead-in area, a data area 40a, and an outer zone area Outer Zone 0. 第二记录层(层1或者L1)包括导出区域,数据区域40b,和外部区区域Outer Zonel。 The second recording layer (Layer 1 or L1) includes a lead-out area, a data area 40b, and an outer zone area Outer Zonel. 第一记录层(层G)的导入区域包括临时缺陷管理区域TDMAl 和多个最终缺陷管理区域DMAla和画A2a。 The first recording layer (layer G) of the lead-in area comprises a temporary defect management area TDMAl and a plurality of final defect management area, and Videos DMAla A2a. 第二记录层(层l)的导出区域包括临时缺陷管理区域TDMA4和多个最终缺陷管理区域DMA lb和DMA2b。 The second recording layer (layer l) of the lead-out area comprises a temporary defect management area TDMA4, and a plurality of final defect management areas DMA lb and DMA2b. 在Outer ZoneO和/或Outer Zonel中也^殳置另外的最终缺陷管理区域(比如,DMAs 3a, 3b, 4a, 4b )。 In Outer ZoneO and / or Outer Zonel ^ Shu also opposed additional final defect management area (for example, DMAs 3a, 3b, 4a, 4b). 第一记录层(层0)的数据区域40a包括内部备用区域ISAO,用户数据区域42a,和外部备用区域OSA0。 A first recording layer (Layer 0) includes a data area 40a 42a, and an outer spare area OSA0 inner spare area ISAO, a user data area. 第二记录层(层1)的数据区域40b包括内部备用区域ISA1,用户数据区域42b,和外部备用区域0SA1。 The second recording layer (Layer 1) of the data area 40b includes an inner spare area ISA1, a user data area 42b, and an outer spare area 0SA1. 外部备用区域OSA0和/或外部备用区域OSAl包括TDMA(比如, TDMA2或T腿A 3)。 Outer spare area OSA0 and / or the outer spare area includes OSAl TDMA (for example, TDMA2 leg or T A 3). 图5中所示的各区域中标出的箭头是数据记录方向的示例。 Each region shown in FIG. 5 is an example of an arrow marked data recording direction. 和单层BD-WO相似,TDMA1和4可以具有固定的容量,而备用区域中的T画A 2和3依据备用区域的容量可以具有可变容量。 Similar single-layer BD-WO, the TDMA1 and 4 may have a fixed capacity, and the spare area A 2 and T Videos 3 based on the capacity of the variable displacement spare area may have. 例如,若OSAO/OSA1具有N x 256蔟的容量,在此N>0( N =整数),则TDMA2/TDMA 3具有P簇的容量,在此P- (Nx 256 )/4。 For example, if the OSAO / OSA1 has a capacity of 256 nest N x, here N> 0 (N = integer), then the TDMA2 / TDMA 3 has a capacity of P clusters where P- (Nx 256) / 4. 如上所述的单层BD-W0的應As和TDMAs的结构和用途同样可用于双层BD-WO的DMAs和TDMAs。 As described above, a single layer BD-W0 should TDMAS As the construction and use and can be used for the same double the BD-WO DMAs and TDMAs. 一个区别是在双层BD-W0的各记录层的DMAla-4b各具有32簇的容量,从而第一记录层中的DMA和第二记录层中的相应的DMA构成了一个完整的DMA。 One difference is that each has a capacity of 32 clusters DMAla-4b in each recording layer of the two-layer BD-W0, so that the first recording layer and a corresponding DMA in the DMA in the second recording layer constitute one full DMA. 比如,DMA la和lb构成一个DMA, DMA 2a和2b构成一个DMA, DMA 3a和3b构成一个DMA,而DMA 4a和4b构成一个DMA。 For example, DMA la and lb constitute one DMA, DMA 2a and 2b constitute one DMA, DMA 3a and 3b constitute one DMA, the DMA 4a and 4b constitute one DMA. 在这点上,同样的信息记录在第一记录层的DAM la, 2a, 3a, 4a各个中。 In this regard, same information is recorded in the first recording layer DAM la, 2a, 3a, 4a of each. 和记录在DMA la, 2a, 3a, 4a中的信息不相同的信息,被记录在丽A lb, 2b, 3b, 4b的各个中。 And recording DMA la, 2a, 3a, 4a information is not the same information is recorded in Korea A lb, 2b, 3b, 4b of each. 当BD-W0完成时(比如,在用户数据区域的数据写4喿作完成,TDMA (s)被装满,或者接到了来自用户、主机、盘制造者的结束命令等), 已经存储在TDMA (s)上的TDMA信息被作为DMA信息写到DMA (s)上。 When the BD-W0 is completed (for example, data written in the user data area 4 is completed as Qiao, TDMA (S) is filled, or received from a user, a host, a disk manufacturer's end command, etc.), already stored in the TDMA information on the TDMA (s) are written to the DMA (s) as DMA information on.
