记录介质,以及用于在同一记录介质上重写数据的方法和 Recording medium, and a method for rewriting data on the same recording medium, and

设备 device

技术领域 FIELD

[0001] 本发明涉及一种记录介质,更具体地说,涉及一种用于在记录介质中记录数据时 [0001] The present invention relates to a recording medium, and more particularly, to a recording medium for recording the data

执行逻辑重写功能的方法和设备。 Method and apparatus for performing logical overwrite function. 背景技术 Background technique

[0002] —般而言,最近开发了一种能够长期记录高质量视频数据和高质量音频数据的记录介质,例如,可重写蓝光光盘(BD-RE)。 [0002] - In general, recently we developed a long-term recording medium capable of high-quality video data and high-quality audio data, for example, a rewritable Blu-ray disc (BD-RE).

[0003] 图1示出普通BD-RE的结构以及用于管理BD-RE的缺陷的方法。 [0003] FIG. 1 shows the structure of a general BD-RE and BD-RE method for managing defects. [0004] 如图1中所示,BD-RE包括引入区段、数据区段以及引出区段。 [0004] As shown in FIG. 1, BD-RE includes introducing zone, data zone and the lead-out zone. 数据区段包括内部备用区(ISA)和外部备用区(0SA)。 Data zone includes an inner spare area (ISA) and an outer spare area (0SA). ISA位于数据区段的前端,而OSA位于数据区段的后端。 ISA data located in the front section, the rear end of the OSA is located in the data segment. [0005] BD-RE将数据记录在簇单元中,每个簇单元对应于一个预定的记录单元。 [0005] BD-RE records data in cluster units, each unit corresponding to a predetermined cluster of the recording unit. 这种情况下,当数据被记录在簇单元中时,BD-RE判定数据区段中缺陷区的存在或缺失。 In this case, when data is recorded in cluster units, BD-RE determines the presence or absence of a defective area in the data section. 如果检测到了缺陷区,将要记录在缺陷区的数据就被记录在前述的备用区,比如ISA,而不是记录在缺陷区,并且与此同时,在引入区段所包含的缺陷列表中,记录与缺陷区相关的位置信息以及记录在前述备用区中的位置信息。 If a defective area is detected, the data to be recorded in the defect area is recorded in the spare area, such as the ISA, and not recorded in the defective area, and at the same time, the defect list included in the lead-in section, the recording and location information related to the defective area and the location information is recorded in the spare area.

[0006] 因此,由于要记录在缺陷区中的数据被记录在备用区中而不是缺陷区中,记录在备用区中而不是缺陷区中的数据可以被读出/再生,以至于BD-RE可以避免在记录/再生数据时生成的意外错误的出现。 [0006] Thus, since the data to be recorded in the defective area is recorded in a spare area instead of the defective area is recorded in the spare area instead of the defective area the data can be read out / reproduction, so that the BD-RE avoided generated when the recording / reproducing data unexpected errors.

[0007] 同时,最近开发了诸如可记录蓝光光盘(BD-R)之类的一次写入光盘。 [0007] Meanwhile, recently developed a write-once optical disc such as recordable Blu-ray disc (BD-R) or the like. 与BD-RE不同,BD-R在整个区域中只能物理地记录数据一次,以至于它不能够向其中物理地重写入数据。 BD-RE with a different, BD-R data is physically recorded only once in the entire area, so that it is not possible to re-write data thereto physically.

[0008] 然而,由于用户可能希望对BD-R中记录的数据进行编辑或改正,为了用户或主机的方便,BD-R可能需要数据重写功能。 [0008] However, since the user may wish to record the BD-R data editing or correction, in order to facilitate the user or host, BD-R function may need to rewrite the data. 因此,必须开发一种有效的方法以使得BD-R可以执行前述的数据重写功能。 Thus, an effective method must be developed so that the BD-R may perform the data overwrite function.

具体实施方式 Detailed ways

[0031] 现在将对本发明的优选实施例做详细的参考,优选实施例的示例在附图中说明。 [0031] Preferred embodiments will be now made in detail to the present invention with reference to the example of preferred embodiments illustrated in the drawings.

[0032] 在下文中将参考附图来说明本发明的优选实施例。 [0032] The preferred embodiments will be described embodiments of the present invention hereinafter with reference to the accompanying drawings.

[0033] 在说明本发明之前,应注意的是本发明中公开的大多数术语对应于本领域内众所周知的通用术语,但是一些术语被申请人因为需要而选择出来,并在随后的本发明的说明中公开。 [0033] Before describing the present invention, it should be noted that most terms disclosed in the present invention correspond to general terms well known in the art, but some terms are selected applicant because of the need, and subsequently present invention Description disclosed. 因此,申请人所定义的术语最好基于它们在本发明中的意义来理解。 Accordingly, the terms defined by the applicant is preferably based on their significance in the present invention be understood.

[0034] —种用在本发明中的记录介质表示所有可记录介质,例如,光盘、磁盘以及磁带等。 [0034] - represents all kinds of recording media, such as optical disks, magnetic disks, and magnetic tape, etc. used in the present invention is a recording medium.

[0035] 为了说明的方便并且为了对本发明的更好的理解,下文中将示例性地使用一次写入光盘(即BD-R)来作为上述本发明中的记录介质。 [0035] For convenience of description and for a better understanding of the present invention, will hereinafter be exemplarily used the write-once optical disc (i.e., BD-R) as the recording medium of the present invention.

[0036] 图2示出一种用于在一次写入光盘(即BD-R)中记录数据的方法。 [0036] Figure 2 illustrates a method for recording write-once optical disc (i.e., BD-R) for the data. [0037] 参考图2,BD-R包括引入区段、数据区段以及引出区段。 [0037] Referring to FIG 2, BD-R includes a Lead-in zone, data zone and the lead-out zone. 数据区段包括内部备用区(ISA)、外部备用区(0SA)以及用于在其中存储真实用户数据的用户数据区。 Data zone includes an inner spare area (ISA), an outer spare area (0SA) and means for storing user data area where user's real data. 该ISA位于数据区的前端,而0SA位于数据区的后端。 The ISA is located in the front end of the data area, and data area located at a rear 0SA.

[0038] 引入区段记录多种向光盘中记录数据/从光盘再生数据所需要的管理信息。 [0038] introduction of various recording section recording data management information / data required for reproducing the optical disc to disc. 具体地说,引入区段还包括临时光盘管理区(TDMA),其中记录有光盘的缺陷管理信息以及记录 Specifically, the introduction section further includes a temporary disc management area (TDMA), wherein the recording disc defect management information and recording

管理信息。 Management information.

[0039] TDMA适于对前述的在使用光盘时经常生成的缺陷以及记录管理信息进行更新。 [0039] TDMA is adapted to the frequently generated when using the optical disc recording and defect management information is updated. 一个附加的TDMA也可视需要被分配给分配前述的备用区。 An additional TDMA may also optionally be allocated to the allocation of the spare area.

[0040] 前述的一次写入光盘(即BD-R)使用两种数据记录方法,即顺序记录模式(SRM) 方法和随机记录模式(RRM)方法。 [0040] the write-once optical disc (i.e., BD-R) using two data recording method, i.e., the sequential recording mode (SRM) method and a random recording mode (RRM) method.

[0041] SRM方法将存储真实用户数据的用户数据区划分为多个连续的区域,使得数据可以被轻松地记录在光盘中。 [0041] SRM method of real user data stored user data area is divided into a plurality of successive regions, so that the data can easily be recorded in the optical disc. 每个前述的被划分的区域被称为轨道或SRR(顺序记录范围)。 Each of the divided regions is referred to as a track or the SRR (sequential recording range). 在本发明中被划分的区域在下文将被称为SRR。 In the present invention, the divided regions will be referred to hereinafter SRR.

[0042] 用在SRR中的数据记录是在表示下一可写未记录簇的未记录簇中实现的。 [0042] The data used in the SRR is recorded in the cluster indicating that the next writable implemented unrecorded unrecorded cluster. 未记录簇的地址被称作下一可写地址(NWA)。 Unrecorded cluster address is called a next writable address (NWA). 换言之,SRR中所包含的预记录区的下一个簇充当NWA,并且数据记录操作在NWA处开始。 In other words, the pre-record area contained in the SRR acts as NWA in one cluster, and the data recording operation is started at the NWA. 因此,如果数据被从特定的位置(即NWA)连续地记录,NWA就随着数据记录操作动态地增长。 Thus, if data is continuously recorded from a specific position (i.e. NWA), NWA will grow dynamically as the data recording operation.

[0043] 在这种情况下,由于NWA的存在,可在其中记录数据的SRR被称为保留SRR或开放SRR。 [0043] In this case, due to the presence of the NWA, data may be recorded in the SRR which is referred to as reserved open SRR or SRR. 为了说明的方便,该SRR在本发明中被称为开放SRR。 For convenience of explanation, the open SRR SRR is referred to in the present invention.

[0044] 可分配两个或更多的开放SRR以执行数据记录操作。 [0044] may be assigned two or more open SRR to perform the data recording operation. 一个SRR可被用作文件系统数据区,用于存储与用户数据相关的信息,而另一个SRR可被用作记录用户数据的用户数据区。 SRR may be used as a file system data area for storing data associated with the user information, the SRR can be used as another user data area for recording user data.

[0045] 文件系统数据表示光盘中所包含文件的名称信息以及光盘记录位置信息,以至于使得用户数据文件可在光盘中记录/从光盘再生。 [0045] The file system data indicates the name information and an optical disc recording position information contained in the file, so that the user data file can be recorded in the optical disk / reproduction from the optical disk. 换言之,主机或应用程序利用前述的文件系统数据来记录或再生光盘中所包含的特定文件。 In other words, the host or application using the file system data is recorded or reproduced in a specific file contained in the disc.

[0046] 因此,上述的文件系统数据包括分级文件/路径的名称信息,以及表示上述文件/ 路径的大小/位置数据的指针信息。 [0046] Thus, the above-described file system data includes a hierarchical file / path name information, and pointer information indicating a size of the file / path / location data.

[0047] 根据上述的SRM方法,在接收到应用程序或主机的请求时,可产生与单个SRR中所包含的预记录区有关的重写命令。 [0047] The SRM method described above, upon receiving the request of an application or a host, produces an overwrite command associated with a pre-recorded area contained in a single SRR. 这种情况下,由于BD-R的特征,光盘记录操作可被物理地执行一次,以至于与预记录区有关的数据记录操作即重写功能是不被允许的。 In this case, due to the characteristics of the BD-R, the optical disk recording operation may be performed once physically, that associated with the prerecorded area i.e. rewriting data recording operation is not allowed. 然而,要记录在上述预记录区中的数据可被记录在下一可写用户数据区中所包含的NWA中,而不是记录在预记录区。 However, data to be recorded in the pre-record area may be recorded in a next writable NWA user data area included instead of the prerecorded area. 上述的替代记录操作被称为逻辑重写操作,该逻辑重写操作与BD-RE的物理重写操作不同。 Alternatively the above-described recording operation is called a logical overwrite operation, logical overwrite of the BD-RE with the physical operation of rewriting different operations.

[0048] 在下文将结合附图对上述的逻辑重写方法进行说明。 [0048] In the above-described below in conjunction with the accompanying drawings logical overwriting method will be described.

[0049] 图3示出了根据本发明的第一优选实施例的用于在BD-R中逻辑重写数据的方法。 [0049] FIG. 3 shows a method for logically overwriting data in a BD-R according to a first preferred embodiment of the present invention. [0050] 参考图3,在接收与单个SRR所包含的预记录区相关的数据记录命令时,要记录在预记录区中的数据被记录在表示下一可写区的NWA中,而不是记录在预记录区中。 [0050] Referring to FIG 3, the relevant data in the pre-record area to receive a single SRR included in the recording command, data to be recorded in the prerecorded area is recorded in the NWA indicates a next writable area, not recorded in the pre-record area. [0051] 更详细地说,如果SRRftl的FS数据区由于NWA的存在而充当开放SRR,数据就记录在SRRftl中所包含的NWA中。 [0051] In more detail, if the FS SRRftl data area due to the presence of the NWA the SRR acts as an open, data is recorded in the NWA contained in SRRftl. 如果SRRft2的用户数据区由于NWA的存在而充当开放SRR,数据就记录在SRR#2中所包含的NWA中。 If SRRft2 user data area due to the presence of the NWA acts as an open SRR, the data is recorded in the NWA contained in the SRR # 2 in.

[0052] 根据本发明,如果出现与一次写入光盘(即BD-R)中所包含的预记录区相关的数据记录命令(即重写命令),数据被记录在与接收道重写命令的区最接近的丽A中,而不是记录在预记录区中。 [0052] According to the present invention, if there is write-once optical disc (i.e., BD-R) data related to a pre-recorded area contained in the recording command (i.e., overwrite command), the data is recorded in the overwrite command receiving channel a region closest to Li, instead of the prerecorded area.

[0053] 因此,正如图3中所见,如果单个的SRR包括NWA,该SRR充当开放SRR。 [0053] Thus, as seen in FIG. 3, including the NWA if a single SRR, the SRR acts as an open SRR. 如果该SRR有足够的空间来存储希望的数据,数据被第一记录在对应的SRR中(即执行了与对应SRR相关的替代记录操作)。 If the SRR has enough space to store the desired data, the data is first recorded in a corresponding SRR (i.e., the replacement record operation is performed to the corresponding SRR is associated).

[0054] 如果如上面陈述地执行了替代记录操作,接收到数据重写命令的区域的第一位置 [0054] If a first position as stated above, the replacement record operation is performed, the received data rewriting command area

信息以及在其处执行替代记录操作的另一区域的第二位置信息被记录在光盘的特定区域 The second position information and the other region of the replacement record operation at which is recorded in a specific area of ​​the disc

中。 in. 例如,第一位置信息和第二位置信息被记录为光盘TDMA的LOW输入项。 For example, the first position information and second position information is recorded as the LOW entry TDMA disc.

[0055] 上述的位置信息可由对应簇的第一物理扇区号(PSN)表示。 [0055] The location information may be a first cluster corresponding to physical sector number (PSN) FIG. 优选地,如果逻辑重 Preferably, if the logical weight

写操作满足多个簇的大小信息,可利用两个输入项分别地对第一簇的第一PSN与最后簇的 A plurality of write operations to meet the cluster size information, and using two entries for the last cluster first PSN of the first cluster, respectively

第一PSN进行记录。 Recording a first PSN.

[0056] 因此,如果用户希望参考在TDMA中记录的LOW输入项信息来再生接收重写命令的第一区的数据,存储在其处执行数据替代记录操作的第二区的数据将被再生,而不是再生存储在第一区中的数据。 [0056] Thus, if a user wishes to reproduce the reference data of the first area receiving the overwrite command in the LOW entry information recorded in the TDMA, at which alternate in the execution data storage area of ​​the second data recording operation will be regenerated, instead of reproducing the data stored in the first region.

[0057] 因此,虽然要记录在接收重写命令的第一区中的数据被物理地记录在充当替代区 [0057] Thus, although the data to be recorded in the first area receiving the overwrite command is physically recorded in functioning as a replacement area

的第二区中,实际的主机识别为数据在接收重写命令的第一区内被重写。 A second region, the actual identification of the host data is rewritten in the first zone receiving the overwrite command.

[0058] 当执行上述的逻辑重写命令时,执行与逻辑重写命令相关联的替代记录操作所在 [0058] When the above logical overwrite command, perform the logical overwrite command associated with the replacement record operation where

的替代记录区域对于替代记录操作可能是不够的,下文将参考图4详细地解释这一点。 Replacement area for recording a replacement record operation may not be sufficient, will hereinafter be explained with reference to FIG. 4 of this detail.

7[0059] 更详细地说,根据重写命令所执行的替代记录操作首先在对应的SRR中被执行。 7 [0059] In more detail, first in the corresponding SRR is performed according to a replacement record operation performed by the overwrite command. 然而,如果对应的SRR中不包含替代记录操作所要求的区域,最好数据被记录在邻近对应SRR的另一个SRR中。 However, if the corresponding SRR is not included in the region required for the replacement record operation, data is preferably recorded in another SRR adjacent in the corresponding SRR.

[0060] 图4表示根据本发明的第二优选实施例的在BD-R中逻辑重写数据的方法。 [0060] FIG. 4 shows a method for logically overwriting data in a BD-R according to a second preferred embodiment of the present invention. [0061] 正如图4中所见,与SRR#1的预记录区相关联的数据重写命令可被其中记录有文件系统(FS)数据的SRR#1接收。 [0061] As seen in FIG. 4, data pre-record area SRR # 1 is associated with the overwrite command can be recorded therein with a file system (FS) of the SRR # 1 receives the data. 这种情况下,如果SRR#1由于NWA的存在而充当开放SRR, 在NWA中执行替代记录操作。 In this case, if the SRR # 1 acts as the presence of the NWA open the SRR, performing a replacement record operation in the NWA.

[0062] 当执行上述的替代记录操作时,替代记录区对于前述的替代记录操作可能是不够的。 [0062] When the above replacement record operation, a replacement record area for the replacement record operation may not be sufficient.

[0063] 这种情况下,对应于SRR#1的剩余区域,数据的替代记录操作被执行数次,其替代记录操作没有被执行的剩余数据被记录在临近的SRR的NWA中。 [0063] In this case, corresponding to the remaining region SRR # 1, data of a replacement record operation is performed several times, an alternative to the remaining data record operation is not performed in the SRR is recorded in the NWA adjacent. 换言之, 一些数据被记录在SRR#1的NWA中,而剩余的数据被记录在临近SRR#1的另一个SRR的NWA中。 In other words, some data is recorded in the NWA of SRR #. 1, and the remaining data is recorded in the SRR # adjacent another of the NWA of SRR 1. 图4示例性地示出在SRR#2中执行的替代记录操作。 FIG 4 shows an example of the replacement record operation is performed in the SRR # 2.

[0064] 这种情况下,其中执行剩余数据的替代记录操作的SRR#2可表示用户数据区。 [0064] In this case, the remaining data in which the replacement record operation of the SRR # 2 may represent user data area. 这种情况下,希望将相同的数据记录在单个SRR中。 In this case, it is desirable to record the same data in a single SRR. 优选地,存储用户数据的SRR#2被关闭, 一个新的SRR被分配,数据被记录在新的SRR中。 Preferably, the SRR # 2 storing the user data is closed, a new SRR is assigned, the new data is recorded in the SRR.

[0065] 例如,SRR#1的数据表示文件系统数据。 [0065] For example, the data of the SRR # 1 represents the file system data. 因此,如果文件系统数据被记录在SRRS2 中,而SRRft2中记录有与文件系统数据不同的用户数据,则SRRft2被自动地关闭,一个新的SRR被分配,并且数据被记录在新的SRR中。 Thus, if the file system data is recorded in SRRS2, whereas SRRft2 recorded in the file system data different from user data, the SRRft2 is automatically closed, a new SRR is assigned, and data is recorded in the new SRR in.

[0066] 因此,存储用户数据的SRR#2被关闭,并且新的SRR#3被分配,以使得用于逻辑重写操作的剩余文件系统数据被记录在SRR#3中。 [0066] Thus, the SRR # 2 storing the user data is closed, and a new SRR # 3 is allocated so that the logical overwrite operation of the remaining file system data is recorded in the SRR # 3.

[0067] 结果,用户数据被记录在SRR#2中,而文件系统数据被记录在SRR#3中,这样上述数据记录操作能够避免由逻辑重写命令引起的不同数据单元被记录在单个SRR中。 [0067] As a result, the user data is recorded in the SRR # 2, and the file system data is recorded in the SRR # 3, so that the data recording operation can be avoided caused by a logical overwrite command different data units are recorded in a single SRR in . [0068] 然后,如果用户想在光盘中重新记录用户数据, 一个新的SRR#4被分配给光盘,这样用户数据被记录在SRR#4中。 [0068] Then, if the user wants to re-record the user data on the optical disc, a new SRR # 4 are allocated to the optical disc, so that the user data is recorded in the SRR # 4.

[0069] 上述的逻辑重写操作从光盘驱动器中生成。 [0069] The foregoing logic is generated from the optical disc drive rewriting operation. 更详细地说,虽然光盘实际等同于BD-R,应用程序或主机可被自由地应用于BD-R,好像BD-R是BD-RE —样,而与BD-R的预记 More specifically, while the optical disc is equivalent to the actual BD-R, or host application program can be freely applied to the BD-R, BD-R seems to be BD-RE - like, with the BD-R pre-credited

录区无关。 Record unrelated area.

[0070] 因此,如果执行逻辑重写操作,应用程序或主机并没识别出:由于上述逻辑重写操作的发生,下一可写区(NWA)被更改为另一个区域。 [0070] Thus, if performing a logical overwrite operation, application or host did not identify: logical overwrite occurs due to the above operation, a next writable area (the NWA) is changed to another region.

[0071] 因此,文件系统可处理其中由于执行重写操作使得NWA被更改为另一个NWA的特定情况。 [0071] Thus, since the file system which can handle rewrite operation is performed such that the NWA NWA is changed to another particular case. 更详细地说,如果文件系统希望执行数据记录操作,它询问光盘驱动器下一可写区(NWA)的位置信息,并且允许数据被记录在对应于该位置信息的更改的NWA中。 More specifically, if the file system performs a data recording operation is desired, it queries the location information of the optical disc drive next writable area (NWA), and allows data to be recorded in the NWA corresponding to the change in the position information. [0072] 同时,新近分配的SRR(即SRR#3和SRR#4)被形成在不用于初始分配的用户数据的SRR#2的分区的旁边。 [0072] Meanwhile, the SRR newly allocated (i.e. SRR #. 3 and SRR #. 4) is formed in the SRR # next partition is not used for the initial allocation of user data 2.

[0073] 虽然本发明的第二优选实施例示例性地示出当在包括文件系统(FS)数据的SRR 内执行逻辑重写操作时提供不充足的替代记录区的特定情况,对于所属领域的技术人员, 明显逻辑重写操作可在其所有区域充满文件系统(FS)数据的关闭的SRR中被执行。 [0073] While the embodiments exemplarily a second preferred embodiment of the present invention shows a specific case of providing an insufficient replacement record area when performing a logical overwrite operation in the SRR including file system (FS) data, for the skilled in the is performed in the art, obvious logical overwrite operation can be filled with all of its area in a file system (FS) data of the closed SRR. [0074] 图5示出根据本发明的第三优选实施例的在BD-R中逻辑重写数据的方法。 [0074] FIG. 5 shows a method for logically overwriting data in a BD-R according to a third preferred embodiment of the present invention. [0075] 正从图5所见,根据本发明的第三优选实施例,当SRR#1的文件系统数据区充满数据以致SRRftl被关闭时,与新文件系统数据相关联的记录命令被应用于被关闭的SRR#1。 [0075] n as seen from FIG. 5, according to a third preferred embodiment of the present invention, when the SRR # 1 is a file system data area is full of data that SRRftl is closed, and the new file system data recording command is applied to the associated closed SRR # 1. [0076] 这样,如果与预记录区相关联的记录命令被应用于SRRftl,要记录在预记录区(即SRR#1)中的数据被记录在距预记录区(即SRR#1)最近的NWA中,而不是记录在预记录区(即SRR#1)中。 [0076] Thus, if the pre-record area associated with the recording command is applied SRRftl, to be recorded in the prerecorded area (i.e. 1 SRR #) is recorded in the data from the prerecorded area (i.e. SRR # 1) Recent the NWA, instead of the prerecorded area (i.e. SRR # 1) in the.

[0077] 因此,数据被记录在包括最临近NWA的SRR#3中,而不是SRR#1中。 [0077] Thus, data is recorded in the NWA comprising nearest the SRR # 3, SRR # 1 instead. 这种情况下, 由于SRR#3表示其中记录有文件系统数据的区域,与SRR#1相同的数据被记录在SRR#3中, 这样数据立即被记录在SRR#3的NWA中,而没有关闭SRR。 In this case, since the SRR # 3 represents a region wherein recorded file system data, the same data is recorded in the SRR # 1 the SRR # 3, so that data is immediately recorded in the SRR # NWA 3, but not closed SRR.

[0078] 与其中执行替代记录操作的光盘相关联,下文将参考图6说明一种用于在关闭的SRR中或在包括不足替代记录区域的用户数据被记录在其中的SRR中逻辑重写数据的方法。 [0078] wherein the optical disc associated with below with reference to FIG. 6, the replacement record operation instructions for insufficient replacement record area comprising user data is recorded in the SRR wherein the logic in the closed SRR or rewriting data Methods.

[0079] 图6示出根据本发明第四优选实施例的在BD-R中逻辑重写数据的方法。 [0079] FIG. 6 shows a method for logically overwriting data in a BD-R according to a fourth preferred embodiment of the present invention.

[0080] 正如图6所见,如果包括用户数据的SRR#2充满数据以致其被关闭,或者如果 [0080] As seen in FIG. 6, if the user data including SRR # 2 is closed so that it is full of data, or if

SRR#2具有不足的替代记录区域,新数据的记录命令可被发送给SRR#2。 SRR # 2 has a region of insufficient replacement record, the new data record command may be sent to the SRR # 2.

[0081] 这种情况下,要记录在SRR#2的数据被记录在最临近的NWA中。 [0081] In this case, to be recorded is recorded in the NWA in the immediate vicinity of SRR # 2 data. 换言之,数据被记 In other words, the data are recorded

录在最临近SRR#2的SRR#3中出现的NWA中。 Recorded in the NWA nearest SRR # 2 of the SRR # 3 appears.

[0082] 这种情况下,SRR#3中记录文件系统数据。 [0082] In this case, SRR # 3 is recorded in the file system data. 因此,如果如前述优选实施例在SRRS3 中执行逻辑重写操作,则在SRRft3中混合有不同的数据单元。 Accordingly, the foregoing preferred embodiments as if performing a logical overwrite operation in the embodiment SRRS3, then mixed with different data units in the SRRft3. 更详细地说,希望相同的数据被记录在单个的SRR中,但由于逻辑重写操作的发生,在单个SRR中实际存在不同的数据单元。 More specifically, the same desired data is recorded in a single SRR but since the logical overwrite operation occurs, the actual presence of the different data units in a single SRR.

[0083] 为了解决上述的问题,希望用户数据被顺序地记录。 [0083] To solve the above problems, desired user data are sequentially recorded. 更详细地说,虽然可在BD-R 的所有区域执行逻辑重写操作,通常对于由文件系统生成的用户数据仅执行顺序记录操作。 More specifically, although the logical operation is performed rewritable BD-R for all areas, usually for the execution sequence generated by the file system only the user data recording operation.

[0084] 根据本发明的光盘包括与开放SRR相关联的信息的顺序记录范围信息(SRRI)头部的"开放SRR列表"域,这样可以利用"开放SRR列表"域容易地在存储用户数据的关闭的SRR上执行逻辑重写操作,并且利用"开放SRR列表"可以避免不同的数据单元被记录在单个的SRR中。 [0084] The optical disk according to the present invention comprises an open SRR information associated with a sequential recording range information (the SRRI) "List of Open SRR" header field, which can use the "List of Open SRR" field is easily stored user data performing a logical overwrite operation on the closed SRR, and using the "list of open SRR" avoid different data units are recorded in a single SRR in. 关于这点下文将参考图7进行详细地说明。 In this regard hereinafter with reference to FIG. 7 will be described in detail.

[0085] 图7是表示根据本发明的用在BD-R中的基于SRM方法的SRRI的结构图。 [0085] FIG. 7 is a diagram for use in a BD-R based on the structure of FIG SRRI SRM method according to the present invention. 更详细地说,图7显示一种根据本发明的第五优选实施例的逻辑重写方法。 More specifically, FIG. 7 shows an example of a logical overwriting method according to a fifth preferred embodiment of the present invention.

[0086] 参考图7, SRRI表示记录在光盘的TDMA中的信息。 [0086] Referring to FIG 7, SRRI represents the information recorded in the TDMA of the optical disc. SRRI包括"SRR输入项列表" 域以及"SRRI终止"域。 SRRI including the "SRR entry list" field and "SRRI termination" field.

[0087] "SRRI头部"域包括"SRRI标识符='SR'"域作为表示SRRI的ID (标识)信息。 [0087] "SRRI header" field includes a "SRRI identifier = 'SR'" field indicates the SRRI as ID (identification) information. "SRRI头部"域还包括"SRR输入项数"域,"开放SRR数"域以及"开放SRR序号列表"域。 "SRRI header" field also includes "the number of SRR entries" field, "open SRR number" field and the "List of Open SRR numbers" field. [0088] 表示SRR输入项数的信息被记录在"SRR输入项数"域中。 [0088] The information indicating the number of SRR entries is recorded in the "Number of SRR entries" field. 表示开放SRR数的信息被记录在"开放SRR数"域中。 It represents the number of open SRR information is recorded in the "open SRR numbers" field. 表示开放SRR序号列表的信息被记录在"开放SRR序号列表"域中。 Open SRR numbers list information is recorded in the "List of Open SRR numbers" field.

[0089] 与开放SRR序号列表相关联的信息被记录在"开放SRR序号列表"域中。 [0089] Information is recorded in the associated "List of Open SRR number" field and the list of open SRR numbers. 正如图7 中可见,从第一开放SRR序号域到第16开放SRR序号域的16个开放SRR序号域的每一个都被分配了两个字节,使得每个SRR序号域在其中记录数据。 As seen in FIG. 7, from the first open SRR number field to open SRR number field 16 of 16 open SRR number field is assigned to each of the two bytes, such that each field in the SRR number recorded therein data. [0090] 这种情况下,前述的SRR序号被以数字递减顺序来分配。 [0090] In this case, the SRR number is the number to be allocated in descending order. 如果被分配的SRRs的序号小于16,数据0被记录在单个未使用的开放SRR序号域中。 If the sequence number is assigned SRRs is less than 16, data 0 is recorded in the open SRR number field of a single unused. 因此,光盘驱动器通过查询"开放SRR序号列表"域来搜索替代可记录SRR。 Thus, the optical disc drive by querying the "List of Open SRR numbers" field to search for alternative recordable SRR.

[0091] 根据本发明,当利用上述的SRRI头部信息在被关闭的SRR中执行逻辑重写操作时,逻辑重写操作被执行以避免不同的数据单元在单个SRR中出现,并且关于这一点下文将参考图8进行详细地说明。 [0091] According to the present invention, when using the header information of the SRRI perform a logical overwrite operation, a logical overwrite operation is performed to prevent different data units present in a single SRR in the SRR is closed, and on this point below with reference to FIG 8 will be described in detail.

[0092] 图8示出根据本发明的第五优选实施例的在BD-R中逻辑重写数据的方法。 [0092] FIG. 8 illustrates a method for logically overwriting data in a BD-R according to a fifth preferred embodiment of the present invention. [0093] 参考图8,如果光盘驱动器希望在预记录SRR或通过用户请求关闭的SRR上执行逻辑重写操作,被关闭的SRR序号被记录在对应于关闭的SRR序号除以开放SRR数所获得的余数的开放SRR的NWA中。 [0093] Referring to Figure 8, if the optical disc drive desires to pre-recorded SRR or overwrite operation by a user request to execute logic on a closed SRR, the closed SRR number is recorded in the obtained corresponding to the closed SRR number is divided by the number of open SRR NWA an open SRR in the remainder.

[0094] 例如,如图8所示,假设关闭的SRR是第0、第1、第2以及第3SRR(即SRR0,SRR1, SRR2以及SRR3),文件系统数据被记录在前述的关闭的SRRO和SRR2中,并且用户数据被记录在前述的关闭的SRR1和SRR3中。 [0094] For example, as shown in FIG. 8, the closed SRR is assumed that the 0th, first, second and 3SRR (i.e. SRR0, SRR1, SRR2 and SRR3), file system data is recorded in the aforementioned closed and SRRO SRR2 and the user data is recorded in the aforementioned closed and SRR3 in SRR1. 如果开放SRR是第4和第5SRR,"开放SRR序号列表" 域存储"开放SRR列表[0] = 4"信息以及"开放SRR列表[1] = 5"信息。 If the open SRR is 4 and 5SRR, "a list of open SRR numbers" field stores "List of Open SRR [0] = 4" and the message "List of Open SRR [1] = 5" information. [0095] 这种情况下,"开放SRR列表"信息的加上括号的字符表示第0开放SRR以及第一开放SRR,因为被分配的开放SRR的数目是2。 [0095] In this case, "List of Open SRR" parenthesized character information represents 0, and a first open SRR open SRR, since the number of allocated open SRR is 2.

[0096] 在上面所提到的记录状态下,如果光盘驱动器希望在利用主机或应用程序请求而关闭的SRRO中执行逻辑重写操作,开放SRR的数目为2,则计算当关闭的SRR数"O"除以2 时所获得的余数。 [0096] In the recording state mentioned above, if the optical disc drive desires to perform logic SRRO application requests the use of the host or closed in rewriting operation, the open SRR number is 2, is calculated when the number of the closed SRR " O "the remainder obtained by dividing 2:00.

[0097] 因为计算所得的余数等于O,用于逻辑重写操作的替代记录操作在第O开放SRR(即具有开放SRR序号4的开放SRR4)的NWA中被执行。 [0097] Since the calculation of the resulting remainder is equal to O, a replacement record operation for the logical overwrite operation (i.e., an open SRR number of open SRR4 4) is performed in the NWA of the open SRR O. 在这种情况下,关闭的SRRO表示包括文件系统数据的SRR,以至于文件系统数据也被记录在其中执行替代记录操作的开放SRR4中。 In this case, the closed SRR represents SRRO include file system data, so that the file system data is also recorded in the open SRR4 wherein performing the replacement record operation.

[0098] 如果逻辑重写命令被传输给关闭的SRR1 ,计算当关闭的SRR序号"1 "除以开放SRR 数(即2)时所获得的余数。 [0098] If the remainder logical overwrite command is transmitted to the closed SRR1, calculated when the closed SRR number "1" by the number of open SRR (i.e., 2) obtained.

[0099] 因为计算所得的余数等于l,用于逻辑重写操作的替代记录操作在第一开放SRR(即具有开放SRR序号5的开放SRR5)的NWA中被执行。 Is performed [0099] Since the calculated remainder is equal to l, a replacement record operation for the logical overwrite operation in the first open SRR (i.e. having the open SRR number of open SRR5 5) of the NWA. 在这种情况下,关闭的SRR1 表示包括用户数据的SRR,以至于用户数据也被记录在其中执行替代记录操作的开放SRR5 中。 In this case, the closed SRR represents SRR1 includes user data, so that user data is also recorded in the open SRR5 wherein performing the replacement record operation.

[0100] 这样,如果光盘驱动器希望在关闭的SRR2中执行逻辑重写操作,替代记录操作在开放SRR4中被执行。 [0100] Thus, if the optical disc drive desires to perform the logical overwrite operation in the closed SRR2, replacement record operation is performed in the open SRR4. 开放SRR4表示包括文件系统数据的SRR。 Open SRR4 represents SRR including file system data. 虽然执行了用于与存储有文件系统数据的关闭SRR2相关联的逻辑重写操作的替代记录操作,不同的数据单元不会在相同的SRR中出现。 Although there are implementation of logic for storing file system data and associated off SRR2 rewriting replacement record operation of the operation, different data units do not appear in the same SRR.

[0101] 如果光盘驱动器希望在关闭的SRR3上执行逻辑重写操作,在开放SRR5中执行替代记录操作。 [0101] If the optical disc drive desires to perform the logical overwrite operation on a closed SRR3, performing a replacement record operation in open SRR5. 因为开放SRR5和关闭的SRR3在其中记录用户数据。 Because opening and closing SRR3 SRR5 in which user data is recorded. 相同的数据可在单个SRR中出现。 The same data may be present in a single SRR.

[0102] 下文将参考图9说明一种根据本发明的用于在BD-R中记录数据的方法。 [0102] below with reference to FIG 9 illustrates a method of recording data in the BD-R according to the present invention.

[0103] 图9表示一种根据本发明的用于在BD-R中记录数据的方法。 [0103] FIG. 9 shows a method of recording data in the BD-R according to the present invention. 参考图9,BD-R包括 Referring to FIG 9, BD-R comprises

引入区段、数据区段以及引出区段。 Introduction zone, data zone and the lead-out zone. 两个或更多的SRR被分配给数据区段以使得可在数据 Two or more data segments are allocated to SRR so that the data can be

10区段中记录希望的数据。 Desired data recording section 10.

[0104] 在这种情况下,如图9所示,三个SRR(即第一到第三SRR)被同时分配给数据区段。 [0104] In this case, as shown in Figure 9, the SRR three (first to third SRR) is simultaneously assigned to the data segment. 第一SRR记录文件系统数据,第二SRR记录用户数据,而第三SRR记录等同于前述文件系统数据的文件系统(FS)镜像数据。 A first SRR records file system data, a second user data is recorded SRR, and the third SRR records file system data is equivalent to a file system (FS) mirror data.

[0105] 文件系统镜像数据等同于文件系统数据,并且适于更稳定地保存表示主要数据的文件系统数据。 [0105] file system mirror data equivalent to the file system data, and adapted to hold more stably showing major data file system data.

[0106] 如果执行逻辑重写操作,即使当数据被记录在三个SRR中,只要该数据按照如上所述的三个SRR被分类,对本领域的技术人员而言,显然逻辑重写操作可被执行以避免不同的数据单元出现在单个的SRR中。 [0106] If the logical overwrite operation is performed, even when the data is recorded in the SRR three, as long as the data are classified according to three SRR described above, to those skilled in the art, the logical overwrite operation can be clearly performed to prevent different data units are present in a single SRR.

[0107] 图10是表示根据本发明的一种光盘记录/再生设备的方框图。 [0107] FIG. 10 is a block diagram of the apparatus according to the present invention an optical disc recording / reproducing.
