Description

可一次记录光盘的重叠记录方法及装置技术领域 Record overlap at once optical disc recording method and apparatus TECHNICAL FIELD

本发明涉及高密度光盘,尤其是指在与BD-WO相类似的可一次记录光盘中的逻辑重叠记录方法及其缺陷管理方法。 The present invention relates to a high density optical disc, particularly to a method similar to the management logic overlap recording method for recording at once optical disc and a defect in the BD-WO phase.

背景技术 Background technique

最近出现了可以在长时间记录存储高画质视频数据和高音质音频数据的新型高密度光记录媒体(HD-DVD),举例来说正在开发蓝光光盘(BD-RE : Blue-ray Disc - Rewritable)。 Recently there has been an optical recording medium can (HD-DVD) in the new high-density storage for a long time record high-definition video data and high-quality audio data, for example, is developing Blu-ray Disc (BD-RE: Blue-ray Disc - Rewritable ).

另一方面,所述BD-RE与图1所示相同,区分分配有导入区(Lead-in Area) 和数据区(Data Area),以及导出区(Lead-Out Area)。 On the other hand, the BD-RE shown in FIG. 1, and lead-in area assigned to distinguish (Lead-in Area) and a data area (Data Area), and a lead-out area (Lead-Out Area). 与此相适应的是,在数据区的前端和后端,区分分配有内备用区(ISA: Inner Spare Area)和外备用区(OSA: Outer Spare Area)。 To adapt, in the front and rear ends of the data area, an inner spare area allocated to distinguish (ISA: Inner Spare Area) and an outer spare area (OSA: Outer Spare Area).

BD-RE以与一定记录单位相应的簇(Cluster)单位加以记录,此时与图1所示相同,在记录数据过程中,检测所述数据区域中否存在缺陷(defect)区域。 BD-RE recording unit corresponding to the certain cluster (Cluster) units to be recorded, the same as shown in Figure 1. In this case, the data recording process, detecting whether said data area defect (Defect) region. 当检测出存在缺陷区域时,向其缺陷区记录的数据,在所述备用区,例如内备用区(ISA) 中进行替代记录的一系列替代记录操作,关于缺陷区域的位置信息以及备用区替代记录的位置信息作为管理信息,在导入区作为缺陷表区域(DFL:Defect List)加以记录存储,在缺陷表区域(DFL: Defect List)中有缺陷管理区(DMA: Defect Management Area )。 When the detected defect region, to which the data recorded in the defective area in the spare area such as the inner spare area (ISA) is carried out a series of replacement record replacement record operation, the position information about the defect area and the spare area substitute recording position information as management information in the lead-in area as a defective area list (DFL: defect List) to be recorded is stored in the defect list area (DFL: defect List) defect management area (DMA: defect management area) in.

由此,所述BD-RE的数据区域中存在缺陷区域时,在其缺陷区域中记录的数据替代记录在所述备用区,进行播放操作时,参照管理信息,替代缺陷区域的数据, 读取播放在备用区中替代记录的数据,由此可事先防止数据记录/播放缺陷。 Accordingly, the data area of ​​the BD-RE in the presence of a defect area is recorded in the defect area in which the replacement record data in the spare area, playback operation, referring to the management information, the defect substitute data area, read Alternatively play data recorded in the spare area, thereby preventing in advance a data recording / playback defect.

另一方面,最近可一次记录的蓝光光盘(BD-WO : Blue-ray disc write once) 的规格化操作正在业界中加以商讨,根据可一次记录的光盘在光盘全部区域只能进行一次记录,与可再记录光盘不同,不可能进行物理上的重叠记录(overwrlte)。 On the other hand, recently recorded at once Blu-ray disc (BD-WO: Blue-ray disc write once) normalized operations are to be discussed in the industry, recorded only once in the entire area of ​​the disc according to the disc can be recorded once, and different rerecordable optical disc, recording can not overlap (overwrlte) physically.

但是,也存在可一次记录光盘中编辑记录数据或者要对相应部分进行修正, However, there are optical disc to record data or to edit the corresponding portion may be corrected time recording,

或者为增加用户或主机等便利而有必要进行重叠记录的情况。 Or the like to increase the convenience of users or hosts necessary overlap recording situation. 另外,在重叠记录过程中,也需要一种管理可检测缺陷区域的方法,现在正需要一种对此有效地方案。 Further, in the overlapping recording process, but also may be a need for a method of managing a defect area is detected, this is now a need for an effective solution.

以下将结合附图对本发明的可一次记录光盘的重叠记录方法及装置的实施方 DRAWINGS The following embodiment of the recording method and apparatus may be overlapping a recordable optical disc of the present invention

式进行详细的描述。 Formula be described in detail.

与此相适应,本发明中使用的术语虽然选择了现在最广泛使用的普遍术语, 但在特定的情况下也用撰稿人自身选择的术语,在这种情况下,相应发明的说明部分中会记录其详细意义,所以不是单纯术语名称的术语,需要掌握本发明进一步阐明。 Correspondingly, the term used in the present invention, in general terms, although the choice is now the most widely used, but the term itself writer selected under certain circumstances, in this case, the respective portions described invention detailed records its meaning, so the term is not simply the name of the term, we need to master to further illustrate the present invention.

图2是依据本发明可一次记录光盘中重叠记录的方法示意图。 FIG 2 is a diagram illustrating the method of the present invention can be redundantly recorded in an optical disc recording time. 与图2所示相同,可一次记录的蓝光光盘(BD-WO)中区分为导入区(Lead-in Zone)、数据区(DataZone)、以及导出区(Lead-out Zone)。 As shown in the same FIG. 2, may be recorded once Blu-ray disc (BD-WO) are divided into a lead-in area (Lead-in Zone), a data area (DataZone), and a lead-out area (Lead-out Zone). 在数据区的前端和后端区分分配有内备用区(ISA : Inner Spare Area)、外备用区(OSA : Outer Spare Area)。 In the front and rear ends of the data area distinguishing the assigned spare area (ISA: Inner Spare Area), an outer spare area (OSA: Outer Spare Area).

与此相同构成的可一次记录光盘中,记录管理信息根据光盘使用中的必要可以进行多次更新,所以作为在光盘内用于记录可多次更新的光盘管理信息的区域, 临时缺陷管理区域(TDMA : Temporary Defect Management Area,以下简称为TDMA')配备在导入区(Lead-in Zone)内。 Optical disc, recording management information can be updated several times in accordance with the necessary use of the disc, so that as the area for recording disc management information may be updated several times within the optical disc, recording the temporary defect management area may be one and the same configuration ( TDMA: Temporary Defect Management area, hereinafter abbreviated as TDMA ') provided in the lead-in area (Lead-in zone) inside.

在TDMA内记录临时缺陷表(TDFL : Temporary Defect List,以下简称为TDFL'),在所述TDFL内包括有缺陷表(List of Defects),它是由记录有实际缺陷区或重叠记录区位置信息等的管理信息的数个DFL条目(Defect List entry)构成。 TDMA is recorded in the temporary defect list (TDFL: Temporary Defect List, hereinafter referred to as TDFL '), within the TDFL includes a defect list (List of Defects), which is recorded by the position information of the actual defective area or overlap recording region several DFL entries and other management information (Defect List entry) constituted. (后面将对此进行详细说明) (Which will be described in detail later)

与此相同区分分配的可一次记录光盘中,在数据区域内存在已完成记录的区域(Previously Recorded Area)时,相应区域作为可一次记录光盘物理特性,不允许重叠记录(Overwrite)。 This same assignment can distinguish a recordable optical disc, a memory area in the data area (Previously Recorded Area) recording has been completed, the corresponding region may be a recordable optical disc as physical properties, does not allow overlap recording (Overwrite).

但是,用户或主机等记录命令与图2所示相同,要求在ab区域(记录完成区域)中进行记录时,在本发明中,执行光盘记录播放的光记录播放装置自身将其替换记录在数据区域内的其它区域。 However, other user or host commands the recording shown in the same FIG. 2, it is required ab area (recording area is completed) when recording, in the present invention, an optical recording playback apparatus performs playback of an optical disc recording itself replaces the data recorded in other regions within the region.

由此,用户或主机对光盘内特定区域记录完成与否可以毫无关联地下达记录命令,这个在可一次记录光盘中也可以像可再记录光盘一样加以使用。 Thereby, the user or host specific area within the optical disc recording unrelated completion can be issued a record command, the disc may also be used as rerecordable optical disc as in the one-time recording can be. 对此与可再记录光盘的物理重叠记录相区域,称为逻辑重叠记录(LOW: Logical Overwrite). This recording and re-recording with overlapping physical area of ​​the disc, called a logical record overlap (LOW: Logical Overwrite).

即,与图2所示相同,对于执行ab区域的记录命令,所述区域因为从物理上讲是已完成记录的区域,所以无法向这一区域再次重叠记录,但是在数据区域内(Data Zone)可替代记录至没有记录数据的cd区域。 That is, as shown in the same FIG. 2, for performing recording command ab region, because the region Physically recorded area is completed, it can not be re-recorded to the overlap region, but in the data area (Data Zone ) Alternatively cd recording region to the no data is recorded. 作为替代记录的区域可以是 As an alternative recording area may be

没有记录数据的用户数据区域(User Data Area)或备用区域(ISA, OSA)。 No user data area for recording data (User Data Area) or the spare area (ISA, OSA).

在与此相同替代记录后,将替换记录区域的信息在光盘内的TDMA中记录为TDFL信息,完成记录命令。 After this same alternative recording, the information recording area is replacement recorded in the TDMA as the TDFL information in the disc, completing the recording command.

对于类似的完成记录的光盘,之后根据用户的要求,主机要求ab区域播放时,光记录播放装置参照TDFL信息,替代ab区域的播放,播放cd区域,由此 For similar optical disc recording is completed, and after the user's request, the host player in claim ab region, the optical record player Referring TDFL information playback apparatus, an alternative area ab, cd play area, whereby

来完成播放命令。 To complete the play command.

另一方面,与此相类似,可一次记录的光盘内存在缺陷区域(Defect area)情况下,要记录在缺陷区域的数据替代记录在备用区域(ISA,OSA),这一方法参照图3 加以说明。 On the other hand, Similarly, the optical disc can be recorded once in the case of a defect memory area (Defect area), data to be recorded in the defect area is recorded in the spare area substitute (ISA, OSA), this process with reference to FIG. 3 to be instructions.

图3是依据本发明可一次记录的光盘中管理缺陷区域的方法示意图。 FIG 3 is a diagram illustrating the method of the present invention an optical disc can be recorded in a defect management area.

与图3所示相同,区分分配有导入区(Lead-inZone),数据区(DataZone)和导出区(Lead-out Zone)的可一次记录光盘中,记录实际数据的数据区域(Data Zone) 内部特定区域可发生有缺陷区域(ab)。 The same as shown in FIG. 3, lead-in area assigned to distinguish (Lead-inZone), data area (DataZone) and a lead-out area (Lead-out Zone) can be once optical disc, data recording area of ​​the actual data (Data Zone) records the internal a defective area may be a specific area (ab) occurs.

所述缺陷区域物理上讲可发生在一个簇(Cluster)或一个以上簇中,图3情况就是数个连续(Consecutive)簇中发生有缺陷的情况。 The defect area may occur in terms of a physical cluster (Cluster) one or more clusters, FIG. 3 is the case of a defect occurs several successive (the Consecutive) cluster. 与此相似,数个连续簇中发生缺陷的情况下,通过光盘驱动器(driver)上的设置(setting),为应对即使是一个簇中发生缺陷,在周围的簇也可能发生损伤或污染的情况,也可能发生缺陷簇周边数个簇同时作为缺陷区域加以处理情况。 Similarly, a case where a defect occurs in a number of consecutive clusters, a CD-ROM drive (Driver) setting (Setting) on, in response to even a defect occurs in one cluster, damage or contamination may also occur in clusters surrounding the case , defects may also occur outside the cluster number of clusters to be processed at the same time as the case where a defect area.

与相相同,数据区域(Data Zone)内发生缺陷区域(ab)时,记录在缺陷区域(ab) 的数据替代记录在备用区域(ISA, OSA),图3的情况就是以在外备用区(OSA)的cd 区域替代记录为例加以说明。 When the phase the same, a defective area (ab) occurs within the data area (Data Zone), data recorded in the defect area (ab) replacement recorded in the spare area (ISA, OSA), the case of FIG. 3 is to the outer spare area (OSA ) of the replacement record area cd an example will be described.

与上所述相同,在外备用区域(OSA)中替代记录的话,与此相关的管理信息在TDMA中通过TDFL信息记录,完成记录命令的执行。 The same as the outer spare area (OSA) are alternatively recorded, then the management information associated with this TDFL information in the TDMA by recording, the recording command execution is completed.

由此,对于这种完成记录的光盘,之后根据用户的要求主机要进行ab区域播放时,光记录播放装置参照已记录的管理信息替代ab区域播放而播放cd播放, 执行播放命令。 Accordingly, when the optical disc for which recording is completed, after the user's request to the host for playback ab region, alternative optical recording management information area ab playback apparatus playing and playing the recorded reference cd player, play command execution.

根据本发明,备用区(spare area)中替代记录的数个连续簇(consecutive multiple Cluster)中发生的缺陷特别称为CRD(Consecutive Real beatable Defect:连续实际可定位缺陷)。 According to the present invention, defect spare area (spare area) in the number of alternatives recorded in consecutive clusters (consecutive multiple Cluster) is particularly referred to CRD (Consecutive Real beatable Defect: continuous real defects may be positioned).

与此相关的是,替代记录在备用区的一个簇中发生的缺陷称为RAD(Realbeatable Defect:实际可定位缺陷)。 Related to this is the alternative recording defect occurs in one cluster of the spare area called RAD (Realbeatable Defect: actual positioning defects). 另外对于一个簇中发生的缺陷,也存在备用区不进行替代记录的情况,这称为NRD(Non-Real locatable Defect:非实际可定位缺陷〉。 In addition to the occurrence of a defective cluster, there are cases where no spare area for recording alternative, which is called NRD (Non-Real locatable Defect: Non-real defects may be positioned>.

与图2和图3的实施例所示相同,本发明的逻辑重叠记录方法在将重叠记录区域数据替代记录在备用区中,发生连续缺陷区域时,将记录在缺陷区域的数据替代记录在备用区的CRD类型相同加以处理。 Example FIGS. 2 and 3 shown in the same, overlapping logical recording method of the present invention in the overlapping recording area of ​​the data recorded in the spare area Alternatively, the occurrence of consecutive defect area, data recorded in the defect area is recorded in a spare alternative CRD regions of the same type to be processed.

由此,在逻辑重叠记录方式中,记录在DFL条目中的形态使用CRD条目类型,对此参照所附图加以说明。 Thereby, overlapping logical record, the record forms used in the DFL entry is CRD entry type, which will be described with reference to the accompanying drawings.

图4是依据本发明的可一次记录的光盘中记录重叠记录管理信息的方法示意图。 The method of FIG. 4 is a schematic view of superimposed recording recording management information based on the one-time recording discs of the present invention.

与图4所示相同,根据依用户要求的主机等的重叠记录(overwrite)命令,重叠记录在已记录的区域时,通过备用区等替代记录与前面所述相同。 Same as those shown in FIG. 4, according to the user when requested by the host like overlap recording (Overwrite) command, in the overlapping recording area recorded by the backup zones the same as the previously recorded alternatively.

这种情况,必要的重叠记录管理信息与连续缺陷簇的替代(CRD)类型相同力口以处J里。 This case, instead of recording management information necessary overlapping consecutive defective clusters (CRD) at the port in the same type of force in J.

即,对于连续缺陷簇的替代(CRD)类型(type),记录在TDMA的管理信息可以使用二个DFL条目表示,与图4所示相同,对于一个条目,"状态1 (status 1)" 字段中通过各DFL条目类型(type)的信息记录是否替换记录的相关信息(例如,如果是'0000',缺陷区表示正常替换记录完成的RAD(Re-allocation Defective)类型或者是CRD(Consecutive Re-allocation Defect)的DFL条目,如果为'0001'虽然是缺陷区域,但表示没有指定替换记录的替代记录区域NRD(Non-Real locatable Defect)类型的DFL条目)。 That is, an alternative for the consecutive defect clusters (CRD) type (type), using two DFL entries can be recorded in the management information indicates the TDMA, the same as that shown in FIG. 4, for one entry, "state 1 (status 1)" field whether replacement recording through the DFL entry type (type) information recording-related information (e.g., if it is '0000', indicating a normal defect replacement area recording completion of RAD (Re-allocation defective) type or the CRD (Consecutive Re- allocation defect) DFL entry, if '0001', although defect area, replacement recording is not specified but said alternative recording area NRD (Non-Real locatable defect) type DFL entry). "缺陷簇第1物理扇区数(Defective Cluster first PSN) "字段中记录发生缺陷的簇的位置信息,此时,上面所说的位置信息记录为相应簇第一个物理扇区数(PSN : physical sector number)。 "Defective Cluster first physical sector number (Defective Cluster first PSN)" cluster position information of a defect occurs in the recording field, at this time, the above-mentioned position information is recorded as a respective first physical cluster number (PSN sectors: physical sector number).

另夕卜,"status 2"字段中,与所述"status 1"字段一同记录各DFL条目类型(type) Another Bu Xi, "status 2" field, the "status 1" field of each record together with the DFL entry type (type)

和属性信息(例如,当'oooo'情况下,表示一个簇中发生缺陷的情况,而'ooor情况 And attribute information (e.g., when 'oooo', it indicates a case where a defect occurs in the cluster, and 'ooor case

表示连续数个缺陷簇的开始(start),当'0010'时,表示连续数个缺陷簇的最后(end)), "替代簇第1物理扇区数(R印lacement Cluster first PSN)"字段中记录缺陷区域替代记录至备用区域内的区域位置信息,此时,位置信息记录为相应簇第一个物理扇区数(PSN)。 Represents consecutive starts (start) cluster number of defects, when '0010', indicates that the last (end)), "substitute cluster number of the first physical sector (R printed lacement Cluster first PSN)" field several consecutive defect clusters Alternatively defect area is recorded into a recording area within the spare area position information, time, location information of the corresponding cluster is recorded as a first physical sector number (PSN).

另夕卜,使用另一个条目在"状态(status) 1"和"状态(status) 2"字段中表现 Another Bu Xi, another entry using "a state (Status)" and "state (status) 2" performance in the field

出各DFL条目类型(type)的信息(特别是在第二个条目的"status 2"字段中记录有告之连续数个缺陷簇和替换簇的末尾(end)的'0010'比特),"Defective Cluster first PSN"字段中,记录有发生缺陷簇的位置信息中最后簇的首个物理扇区数(PSN), 在"R印lacement Cluster first PSN"字段中记录有缺陷区域替代记录至备用区内的区域位置信息中最后簇的第一个物理扇区数(PSN)。 Each type of the DFL entry (type) of the information (particularly the second entry in the "status 2" field is recorded Advertisement several consecutive defective clusters and the replacement end (end) clusters '0010' bit), " defective cluster first PSN "field, recording the last cluster number of the first physical sector location information of the defective cluster has occurred (PSN of), in the" R printed lacement cluster first PSN "field of a defective area is recorded into the spare replacement record area last physical cluster number of the first sector in the region position information (PSN).

此时, 一个条目由8字节(64比特)构成。 At this time, an entry (64 bits) is constituted by 8 bytes. 为"status"字段分别分配4比特,为"Defective Cluster first PSN","Replacement Cluster first PSN"字段各分配28比特。 For the "status" field 4 bits are allocated as a "Defective Cluster first PSN", "Replacement Cluster first PSN" field is allocated to each 28 bits.

使用具有与此相同构造的本发明条目格式,体现重叠记录方法的图4举例说明的话,第一个条目(DFL entry 1)口"status 1"字段中记录有表示替换记录的'0000',在"Defective Cluster first PSN"字段中记录有缺陷簇首个物理扇区数'a'。 Having this same configuration entry format according to the present invention embodied in FIG overlap recording method 4 illustrates the case, the first entry (DFL entry 1) mouth "status 1" field is recorded represents a replacement recording '0000', the "defective cluster first PSN" field of a defective cluster is recorded in the first physical sector number 'a'.

另夕卜,"status 2"字段中记录有表示连续缺陷簇开始的'0001',在"R印lacement Cluster first PSN"字段中记录有缺陷区替换记录至备用区内的位置首个物理扇区数'c'。 Another Bu Xi, "status 2" field represents consecutive defective clusters is recorded beginning of '0001', the "R printed lacement Cluster first PSN" field of the defect area is recorded in a replacement recording in a spare area to a first position of a physical sector number 'c'.

另外,第二个条目(DFL entry 2)口"status 1"字段中记录有表示替换记录的'0000',在"Defective Cluster first PSN"字段中记录有缺陷溪最后蔟的第一个物理扇区数'b", "status 2"字段中记录有表示连续缺陷簇末端的'0010',而在"Replacement Cluster first PSN"字段中记录有缺陷区替换记录至备用区域内位置的最后簇的首个物理扇区数'd'。 Further, the second entry (DFL entry 2) mouth "status 1" field is recorded in the replacement recording expressed '0000', in the "Defective Cluster first PSN" field is recorded in the first physical sector of the nest last defect Creek number 'b "," status 2 "field is recorded represents consecutive defective clusters end of' 0010 ', and in the" recording defect area replacement recording to the last cluster of the spare area locations of the first replacement cluster first PSN "field a physical sector number 'd'.

由此,之后,根据用户的要求,主机(host)等要求ab区域播放时,参照TDMA 区域中记录的信息,只运行cd区域播放就可以。 Thus, after the user's request, the host (Host) requirements ab playing area, referring to the information recorded in the TDMA area, playback operation can only cd region.

另一方面,与此相同,对于使用DFL条目二个(DFL entry 1, DFL entry 2)表示重叠记录相关的管理信息的方法,所述二个条目总称命令为CRD条目。 On the other hand, this same, using two DFL entries (DFL entry 1, DFL entry 2) represents the overlap recording management information related to the method, the two generic name entry command CRD entry.

图5是依据本发明可一次记录光盘中已记录区域中存在缺陷区域时,重叠记录的方法示意图。 FIG 5 according to the invention is a recordable optical disc may be a defect area, recording methods schematic overlapping area exists in a recorded.

图5中的(a)表示的光盘是可一次记录光盘中已记录的区域示意图,与图5中的(a)相同,所述光盘的已记录区域具有缺陷区域。 The optical disk of FIG. 5 (a) shows a schematic view of the area of ​​the optical disc is recorded a recording time, the same as in FIG. 5 (a), the optical disk has a defect area recorded region.

与缺陷区域相关的管理信息记录在光盘内TDMA区域(未图示),特别是为RAD类型时,记录在所述缺陷区域的数据替换记录在备用区域中。 Associated with the defect management information recording region (not shown), especially for the RAD type, data recorded in the defect area is replacement recorded in the spare area in the TDMA area within the optical disc.

如此,包括缺陷区域的已记录区域中根据主机命令重叠记录时,不受所述缺 Thus, a recorded area including the defective area according to the host command overlap recording, from the lack of

陷区域局限,在光盘中替换记录在替代记录区域中。 Depression area limitation, the replacement recording in the optical disc replacement record area.

即,与所述缺陷区域的相关管理信息和所述缺陷区域中记录的数据是否替换记录无关,在光盘上的替代记录区域中进行逻辑重叠记录。 That is, management information associated with the defective area and data recording area of ​​the defect regardless of whether the replacement recording, the replacement record logical overlapping recording area on the optical disc. 这也就是可一次记录光盘特性上已记录区域中因为无法记录数据而不受缺陷区域局限的原因。 This is the reason may be a record in the area because they can not record data without the limitations of the defect area has been recorded on a CD-ROM features.

由此,与图5中的(b)相同,对ab区域的逻辑重叠记录完成后,表示光盘TDMA 区域中记录的最初七个缺陷区域相关信息的7个DFL条目中,包括重叠记录区域ab区域的相关信息,记录为6个DFL条目。 Thus, FIG. 5 (b) the same, after the logic ab overlap recording region is completed, it represents the first seven seven DFL entry area of ​​the disc defect TDMA area related information is recorded in a recording area comprising overlapping area ab the relevant information is recorded as 6 DFL entries. (一个CRD条目表示为二个DFL条目) (CRD entry is represented as a two DFL entry)

图6是依据本发明可一次记录的光盘中替换记录的区域存在缺陷区域时重叠记录的方法示意图。 FIG 6 is a schematic of a process when there is overlap recording defective area replacement recording disc according to the present invention may be recorded in one area.

与图6所示相同,光盘上用户数据区域(Userdata area)中存在已完成记录的区域(Previously recorded area),所述已记录的区域中对于ad区域要进行重叠记录时,对于光盘上没有记录数据的eh区域可以进行记录与前面所述相同。 The same as shown in Figure 6, the presence of the recording area has been completed (Previously recorded area) the user data area (Userdata area) on the optical disc, the recorded region in respect to the overlapping recording area to ad, not for recording on the optical disk eh recording area in which data can be the same as previously described.

此时,所述替换记录的eh区域中可能发生缺陷区域(Xm)。 In this case, the replacement recording area may occur eh defect area (Xm). 这种情况下,光记录装置根据缺陷管理方法,将缺陷区域(Xm)中记录的数据替换记录在光盘备用区域(ISA, OSA)。 In this case, the optical recording apparatus according to a defect management method, the defect region (Xm of) the data recorded in the optical disc recording replacement spare area (ISA, OSA).

与此相同重叠记录之后,所述替换记录的区域相关信息应记录在DFL条目中, 根据本发明可以想见下面的方法。 After recording the same overlap, the replacement area information recorded in the DFL entry to be recorded in accordance with the present invention, the following method can imagine.

即,所述逻辑重叠记录区域ad区域相关信息,和替代记录的eh区域相关信息用CRD条目记录后,所述替换记录的区域中发生的缺陷区域(Xm)和所述缺陷区域中记录数据替换记录的区域的相关信息用RAD条目加以记录的方法。 That is, after the logic overlapping area ad information recording area, and the replacement record area information with eh CRD entry recorded defect area (Xm of) the replacement recorded area occurs in the defect area and the replacement recorded data the method of information recording area to be recorded by the RAD entry.

但是这种方法,之后为读取ab区域光记录播放装置读取ab区域,发生再次要读取所述缺陷区域的替代记录区域的问题。 However, this method, after the reading of the recording area of ​​the optical playback apparatus ab ab reading area, the problem occurs again to read the defect replacement record area region. 这个因为DFL条目反复制作所以影响到光记录播放装置的处理速度。 The DFL entry repeatedly made so as to affect the processing speed of the optical recording playback apparatus.

由此,依据本发明,逻辑重叠记录时替代记录区域发生缺陷区域时,使用DFL 条目记录各分别相应CRD条目,记录为互不重叠的CRD条目和RAD条目的方法。 Thus, according to the present invention, the recording area logically replace defective area occurs, using the DFL entries respectively corresponding to the respective recording the CRD entry is recorded as RAD and CRD entry method entries do not overlap when overlap recording.

为此,与图6所示相同,与替代记录区域eh中发生的缺陷区域(Xm)相应的位置已记录(Xm')视为缺陷区域,分别分离所述视为缺陷区域和逻辑重叠记录进行的区域,按数椐播放顺序记录至DFL条目。 For this reason, the same as shown in FIG. 6, a position corresponding to a defective area (Xm of) the occurrence of replacement record area in the recorded-eh (Xm ') considered as a defect area, and separating the considered logical defect region overlapping records, respectively area, a DFL entry according to the recording playback sequence number noted.

由此,对于图6情况,记录为总共三个DFL条目,最初已记录的ab区域中记录的数据替代记录在ef区域的信息记录至CRD条目1中。 Thus, for the case of Figure 6, a total of three DFL entries is recorded, ab area was originally recorded in the data recording to an alternative recording a CRD entry information ef region.

CRD条目1中与前面所述相同,首个DFL条目的"Status 1"字段中记录为'0000', "Defective Cluster first PSN"字段中记录为'a', "Status 2"字段中记录为糊r, "Replacement Cluster first PSN"字段中记录为'e'。 CRD entry 1 is the same as previously, "Status 1" field of the first DFL entry is recorded as '0000', "Defective Cluster first PSN" is recorded as 'a', "Status 2" field is a field recorded paste r, "Replacement Cluster first PSN" field is recorded as 'e'. 另外,第二个DFL条目的"Status r字段中记录为'OOOO', "Defective Cluster first PSN"字段中记录相应簇第一个物理扇区数'b", "Status 2"字段中记录'0010',而"R印lacement Cluster first PSN"字段中记录相应簇第一个物理扇区数T。 Further, the second DFL entry "Status r field is recorded as 'OOOO'," Defective Cluster first PSN "field of the corresponding cluster is recorded in the first physical sector number 'b", "Status 2" field of record' 0010 ', and "R printed lacement cluster first PSN" field of the corresponding cluster is recorded in the first physical sector number T.

另外,视为已记录区域上缺陷区域的区域(Xm')因为一个簇中发生缺陷所以记录为RAD条目类型,在"Status 1"字段中记录为'0000',在"Defective Cluster first PSN"字段中为'b',在"Status 2"字段中记录为'0000',在"R印lacement Cluster first PSN"字段中记录为'i'。 In addition, the region (Xm of ') defective area on the recording region considered to have occurred because of a defect cluster is recorded so RAD type entry, the "Status 1" field is recorded as' 0000', in the "Defective Cluster first PSN" field for 'B', is recorded as "0000" in the "Status 2" field is recorded as 'i' in the "R printed lacement Cluster first PSN" field.

另外,cd区域中要记录的数据替换记录在gh区域的信息记录在CRD条目2中,首个DFL条目的"Status 1"字段中记录为'0000', "Defective Cluster first PSN" 字段中记录为'c', "Status 2"字段中记录为'0001',而在"R印lacement Cluster first PSN"字段中记录为'g'。 Further, the data cd area to be recorded in the replacement recording information is recorded in gh region of the CRD entry 2, "Status 1" is recorded in the first DFL entry field to '0000', "Defective Cluster first PSN" field is recorded as 'c', "Status 2" field is recorded as '0001', and recorded as 'g' in the "R printed lacement Cluster first PSN" field. 另外,第二个DFL条目的"Status 1"字段中记录为'0000', "Defective Cluster first PSN"字段中记录为相应簇第一个物理扇区数'd",而"Status 2"字段中记录为'0010', "R印lacement Cluster first PSN"字段中记录为相应簇首个物理扇区数'h"。 In addition, "Status 1" field of the second DFL entry is recorded as' 0000 ', "Defective Cluster first PSN" field of the corresponding cluster is recorded as a physical sector number' d ", and" Status 2 "field is recorded as' 0010 ', "R printed lacement cluster first PSN" field is recorded the corresponding cluster first physical sector number' h ".

由此,之后光记录播放装置要播放光盘上ad区域时,通过所述记录的DFL 条目信息,直接进行相应替代记录区域(ef,i区域,gh区域)的播放,来提高光记录播放装置的播放性能。 Thus, after the optical recording playback apparatus to play region ad the optical disc, by recording the DFL entry information directly corresponding replacement record area (ef, i region, gh region) play to improve the optical recording playback apparatus playback performance.

与所述说明相同,可一次记录光盘中替代记录的区域中如果存在缺陷区域时, 重叠记录的方法参照附图7的作业表加以说明。 The description of the same, if the defect area exists in the alternative recording area of ​​the optical disc, the recording method of the overlapping operations will be described with reference to the accompanying drawings in Table 7 may be one-time recording.
