第二保護區、第二類資訊、OPC、保留區以及第一類資訊。 第一保護區係指防止BCA覆寫PIC之保護區域。該 P 1C區域係一區域，其中以預先記錄的刻痕儲存一般相關 於光碟和各種其他資訊。第二保護區係一緩衝區，供自預 先記錄區域轉換至可覆寫區域，而第一及第二資訊區域各 自用以儲存相關於光碟或應用之特定資訊，諸如控制資訊。 第1B圖和第1C圖所示為一 RUB(記錄單元區塊），定 義於所討論之光碟標準中。一對應於單一 ECC(Error Correction Code,錯誤修正瑪）之單一 RUB係由起始區、實 體叢集、結束區及保護區域所構成，如第1B圖所示。如 果許多RUBs，或稱.為連續RUBs，一次被創造了許多，用 以儲存即時輸入資料，例如，A/V資料、一組起始區、實 體和結束區被反複創造達到所需數量，並在結束時形成一 保護區域‘Gurar_3’，如第1C圖所示。 如第2 A圖所示，起始區係由一 1 1 0 0通道位元之保護 區域‘Guar d_l’及一個1660通道位元之前置區域‘PrA’所組 成。5 5 個 2 0通道位元型態之複本被寫入於防衛區域 ‘Guard_l’以標示 RUB之表頭，而第一同步資料‘SyncJ’ 和第二同步資料‘Sync_2’被寫入於前置區域‘PrA’之中。其 1330358 中，Sync_l和Sync_2具有30通道位元之長度。每一同步 資料係由24位元之同步本體和6位元之同步ID所構成。 該第一和第二同步資料之同步IDs各為‘000 1 00’（FS4)和 ‘0 1 0 000，（FS6)。 如第2 B圖所示，結束區係由一 5 4 0通道位元保護區 塊‘Guard_2’和一 564通道位元之後置内容‘PoA’所組成。 其中，PoA包含第三同步資料‘Sync_3’。該第三同步資料 亦由24位元之同步主體和6位元之同步ID所構成。又該 第三同步資料之同步ID為‘000 00 1’（FS0)。 保護區域‘Guard_2’被創造以防止在預先記錄資料和 欲記錄的新資料間之覆蓋。又它具有27個20通道位元型 態之複本，用以標示稱為僅記錄RUB之預先記錄區域的結 束0 使用者資料被寫入於實體叢集中而它經由訊號處理器

碼都被用到而每一框架同步代碼由 2 4位元同步本體和 6 位元識別型態所構成。 每一對應於前述單一 ECC區塊之RUB，具有實體位址 7 1330358 資訊，例如，位址單位碼（Address Unit Number, AUN)，用 以隨機存取寫入於一 BD-RE之隨機RUB。在調整（modulate) 及和 A/V資訊一起編碼後，該實體位址資訊被寫入於一 RUB之一實體叢集中。此外，一 AUN係導源於實體區塊 碼（physical sector number, PSN)，而實際上，該實體區塊 碼沒被寫入於一 BD-RE之中。 只能寫入一次和可覆寫光碟（DVD-R，-RW，-RAM, +R， + RW)中，在新的資料以不連續於先前記錄而被記錄之前， 一連結框架被產生於先前記錄區域之後。然而，一唯讀光 碟’諸如DVD-ROM和視訊CD不需要任何連結框架以連 接兩個資料區塊，因為它包含了完整記錄之資料。 儘管可寫入和唯讀光碟間有著差異，皆需要一普通之 光碟播放機’諸如DVD-Player和DVD-ROM以裝備額外之 實體和/或軟體，供播放此兩類型之光碟。 自不待言’ 一能夠記錄和播放可寫入光碟之光碟機亦 需配備額外之實體和/或軟體以播放唯讀光碟以及可寫入 光碟。 同時，稱為‘BD-ROM’之高密度唯讀記錄媒體的標準亦 和BD-RE

第一，依據本發明建構之高密度記錄媒體的連接區域 和相關於該連接區域之資料記錄方法，亦稱資料生成方 法，將詳述於後。 下文中，詞彙「寫入（write)」、「記錄（record)」和「生 成（form)」對唯讀記錄媒體而言，具表示相同之意思。此 外，一生成於連接區域之框架稱為連接框架或記錄框架。 (1)連接區域之架構 一高密度唯讀記錄媒體，例如，一依據本發明建構之 BD-ROM具有參照第1圖和第2圖所述之實體格式（由起始 區域、實體叢集 '結束區域和保護區所構成）。又第1圖和 第2圖係敘述高密度可覆寫記錄媒體。然而，BD-ROM上 符合於可覆寫記錄媒體元件格式之區域可各別以不同名稱 命名。 本發明第一個實施例之開始區域，如第3 A圖所示， 由一保護區域^Guard—l’和一前置區域‘PrA’所構成’又該 前置區域包含兩同步資料。每一同步資料由24位元同步本 體和6位元之同步ID所構成。 當BD-RE中前置區域同步資料之同步IDs各為‘000 13 1330358 100’和{010 000’時，如第2A圖所示’依據本發明所建構 之 BD-ROM的前置區域包含兩同步資料，其 IDs為 FS〇r〇00 001，）（Sync_3)和 FS6(‘0 1 0 000，）（Sync_2)。又該 同步資料‘Sync_3’置於同步資料1γη<:_2’之前。 此外，依據本發明所建構之BD-ROM結束區域的後置 區域（PoA)，如第 3B 圖所示，包含 ID 為 FS4(‘000 100’）（Sync_l)之同步資料。有一相異處，即BD-RE中同步 ID為FS0(‘000 001，）之同步資料係寫入於一 BD-RE之後置 區域。 在BD-RE中，如果產生兩RUBs，而一對開始區域和 結束區域亦如第1 C圖所示生成。該對開始和結束區域（對 應於一連接區域）包含三個記錄順序為‘Sync_l ’、‘Sync_2’ 和‘ Sync_3 ’之同步資料》順帶一提的是，bd-ROM中之記 錄順序為 ‘Sync_3’、lSync_2，和 ‘ Sync_l，，相反於 BD-RE 之順序。 因此’雖然依據本發明所建構之BD-ROM相似於 BD-RE之實體記錄格式’仍可以連接區域中同步資料之寫 入順序區別於BD-RE。此外，亦可以同步資料之佈置，輕 易地斷定是否現有之區域為BD-ROM之連接區域。 在上述實施例中’開始區域、結束區域和保護區域 ‘Guard-3’可能包含之資訊相似於在BD-RE上對應區域之 記錄。 BD-ROΜ連接區域之結構可如揭示本發明第二實施例 之第4Α圖所示’以不同之方式定義。如第4Α圖所示，在 14 1330358 而在BD-RE之一例中，相異 域和27 60位元之結束區域構成 BD-ROM之一例中，知m 同大小（1932通道位元）之兩連 架構成一單一連接區域 之1 104位元之開始區 一連接區域。 該兩連接柩架传 > 丄 糸在相同的架構而任一框架由3〇 位70框架同步代碼、9位元組實體位址、i "位元組使 資料和32位元組奇偶校驗位所構成。 該U4位元組使用者資料可以包含一多種額外資 例如，防盗版資訊（用以防制非法複製諸如記錄 BD-R0M上之電影至其他的媒體上）、控制資訊（供伺 制操作之用）。 第4B圖所示為本發明之第三實施例。第三實施 之連接區域係由兩相等大小（1 932通道位元）之連接框 構成’而每一框架係由一 3〇通道位元框架同步代碼、 元組實體位置和1 4 6位元組使用者資料所構成。相較 4A圖’第4B圖之實施例之差別是沒有奇偶校驗位。 有用之資訊可以被寫入於該146位元組使用者資 間。該有用資訊為反盜版資訊（用以防制非法複製諸 錄於一 BD-ROM上之電影至其他的媒體上）、或控制 (供伺服控制操作之用）。 第4C圖所示為本發明之第四實施例。第四實施 之連接區域係由兩相等大小（1 9 3 2通道位元）之連接框 構成，而每一框架係由一 30通道位元框架同步代碼-位元組使用者資料所構成。相較於第4A圖’第4C圖 接框 大小 一單 通道 用者 訊， 於一 服控 例上 架所 9位 於第 料空 如記 資訊 例上 架所 • 155 之實 15 1330358 施例之差別是沒有實體位址和奇偶校驗位。該實施例亦因 沒有實體位址相異於第4B圖。 第4D圖所示為本發明之第五實施例。第五實施例上 之連接區域係由30通道位元前方框架同步代碼、3714通 道位元之連接部位、兩個30通道位元之後方同步代碼和分 別為40和20通道位元長度之兩複本模組所構成。 該3714通道位元之連接部位係由三個連接框架和4 位元填充資料所構成"一連接區域可以具有任何異於上述 内容之可能架構。 資料以ECC區塊之格式寫入於實體叢集甲，而上述七 種框架同步代碼FS0〜FS6通常用於ECC區塊。 如第4A圖所示之兩個連接框架至之至少一個使用新 框架同步代碼‘FS η’’又其同步ID相異於上述七個框架同 步代碼。新-框架同步代碼之同步 ID 4FS Ν’為‘1〇〇 101’（FS7) 、 ‘101 〇l〇’（FS8) 、 ‘〇1〇 i〇i，（FS9) 、 ‘101 OOI’（FSIO)，如第5圖所示。 所有這四個同步代碼之選擇滿足專屬於BD-RE之轉 換限制，即位元模組不能短於2位元。 在第4A圖之記錄實施例中，框架同步代碼FS0係寫 入於第一連接框架，而框架同步代碼‘FS η’則在第二連接 框架。 此外，記錄於一 BD-RE之資料必須滿足1 7ΡΡ(奇偶校 驗位預留）調整所限制之「禁止 RMTR(Run-Limited Transition，執行有限轉換）」。該限制係BD-RE所定義之資 16 1330358 料記錄標準。 該禁止RMTR之限制（用以確保對RF訊號做穩定之偵 測）係最小執行長度2T，即為4 〇 1，或‘ 1 〇，不能被連續重複超 過六次。因此，它傾向於以小的轉換頻率使用一框架同步 代碼，即為‘100 101，（FS7)或‘101 001’（FS10)在新的框架同 步代碼_達成滿足限制之位元轉換。框架同步代碼之使用 將參照第6A圖做詳細解說》 圖示於第 6A圖之第一種狀況為本發明之第一實施 例。在實施例中’兩1 9 3 2通道位元之記錄框架被記錄於一 連接區域’而每一記錄框架由一框架同步代碼、一實體位 址、使用者資料和奇偶校驗位所構成。該兩個記錄框架之 至少一個包含最新定義之框架同步代碼‘FS η，。 例如’框架同步代碼‘ F S 〇 ’及它的識別模組（id)被寫入 為第一框架同步代碼，而識別模組為‘〇1〇 1〇1，、 M〇1 〇1〇, 或‘100 101’之新的框架同步代碼‘FS n，則被寫入為第二框 架同步代碼。 當同步識别模組為‘〇1〇 101，、‘101 010，或‘1〇〇 1〇1， 之新的框架同步代碼‘FS n，被使用時，框架同步代碼‘FS n， 之後的9位元組實體位址具有一未擾頻之起始資料‘〇〇，， 如第6Α圖所示。這是因為它有助於滿足17ΡΡ調整碼之 RMTR條件。又該i 7ρρ調整碼之定義係供作bd-RE上資 料記錄之用。 例如’如果具有同步識別模組‘丨00丨〇 1 ’之新的框架同 步代碼FS7被使用，而同時其後之實體位址位元為‘〇ι n 17 1330358 01 11’，其經由第7D圖所示之17PP調整表所做的調整位 元為‘ 0 1 0 1 0 1 0 1 0 1 0 Γ，則最終包含同步識別模組之調整 位元構成‘100 101 010 101 010 101’，其中2T模組（一個零 介於兩個鄰近之一的模組）持續出現7次。 然而，如果實體位址在它的表頭包括‘ 0 0 ’，則上述實 體位址之示例變為‘00 01 11 01 11’，而其17PP調整位元 變為‘010 100 101 010 10Γ。因此，具有同步識別模組之 最終位元構成‘100 101 010 100 101 010 101’。其中，一個 3 T和四個2 T模組相繼出現。 如第6 A圖所示之第二種狀況係本發明第二實施例。 該實施例中，二1932通道位元之記錄框架被記錄於一連接 區域，而每一記錄框架係由一框架同步代碼、一實體位址、 使用者資料和奇偶校驗位所組成。兩記錄框架之至少一個 包含框架同步代碼FS10(‘101 001’），最新定義之框架同步 代碼‘ F S η ’之一。 例如，識別模組為£ 0 0 0 0 0 1 ’之框架同步代碼F S 0被寫 入為第一框架同步代碼，而新的框架同步代碼FS10被寫 入為第二框架同步代碼。 當新的框架同步代碼‘FS10’被使用時，自動滿足在 BD-RE上定義為資料記錄所用的1 7ΡΡ調整碼之RMTR限 制。所以，其後之實體位址不以‘ 〇〇 ’為開頭。 例如，如果識別模組為Μ 0 1 0 0 Γ之新框架同步代碼 FS10被使用，而同時其後之實體位址位元為‘〇1 11 01 11’，其經由第7D圖所示之17ΡΡ調整表所做的調整位元 18 1330358 為‘ 0 1 0 1 0 1 0 1 0 1 0 Γ，則最終包含同步識別模組之調整位 元構成 ‘101 001 010 101 010 101’，其中出現一個 2Τ、一 個3T和6個2T模。 如第6B圖所示之第三種狀況為本發明第三實施例。 在該實施例中，兩個1 9 3 2通道位元之記錄框架被記錄於一 連接區域，而每一記錄框架由一框架同步代碼、一實體位 址、使用者資料和奇偶校驗位所構成。該兩個記錄框架皆 包含新定義之框架同步代碼‘FS η’。 例如，第一和第二框架同步代碼係利用下述新的框架 同步代碼之一，即 FS7(‘010 101，） 、FS8(‘101 010’）和 FS9(‘ 100 101，）。 當新的框架同步代碼 FS7、FS8或FS9被使用時，框 架同步代碼FS7、FS8或FS9之後的9位元組實體位址具 有未擾頻之起始資料‘〇〇’，如第6A圖所示。上述種種是為 了更能滿足在BD-RE上定義為資料記錄所用的17PP調整 碼之RMTR限制。 當新的框架同步代碼FS7(‘100 101’）被使用時，則藉 由寫入實瘇位址空間於具有資料的該框架同步代碼之後而 非‘ 0 1 11 0 1 11 ’之後，可以滿足RMTR限制。 如第 6B圖所示之第四種狀況為本發明第四實施例。 在該實施例中，兩個1 9 3 2通道位元之記錄框架被記錄於一 連接區域，而每一記錄框架由一框架同步代瑪、一實體位 址 '使用者資料和奇偶校驗位所搆成。該兩個記錄框架皆 包含新框架同步代碼FS10(‘10 001’）。 19 1330358 當新的框架同步代碼ISIO’被用於兩種 自動滿足在BD-RE上定義為資料記錄所用合 之RMTR限制。所以，每一框架同步代碼後 以‘ 0 0 ’為開頭。 如果新定義之框架同步代瑪‘FS η’被用 是否一現有區域位在一連接區域之中，可被 判斷，因為該新的框架同步代碼異於實體叢i 例如，當框架同步代碼之結合被用以判 時，因為一框架同步代碼之結合係由寫入於 ‘FS η’及FS4所構成，則各自寫入於前一實 29和第3 1記錄框架（記錄框架#28至#30)之 為FSn-FS4或FSn-FS2，又其明顯相異於寫 集的框架同步代碼所產生之結合。是否一現 接區域之中，係以框架同步代碼之結合為基 定。 上文所述之七種情況摘要如下。 如果適當之限制被施加於欲寫入一框架 的資料，則任何其他四個框架同步代碼皆可 例如，假如在框架同步代碼後面寫了一 如果實體的位址總有一位元‘ 00 ’之標頭，則 代碼FS8及FS9可以無阻礙地被使用。 在未寫入一實體位址的特殊情況中， 組，例如’ 4 0 8 h ’（ 0 0 0 0 1 0 〇 〇)沒有恰在框架同 擾頻寫入，藉由1VPP自508h’所調節之位 資料框架時， !) 1 7PP調整碼 之實體位址不 於上述狀況， 輕易而準確地 I上所使用者。 別現有之區域 ~~連接區域之 體叢集中之第 FS4和FS2變 入於一實體叢 有區域在一連 礎做精確之確

larger than the general DVD made by the relevant company. The amount of suba is as shown in Fig. 1A, and a rewritable optical disc BDRE-^ is divided into the following regions, a sweet region 1'-converted region 9'@2, a burst cutting area (BCA) 3, a lead-in area to find the rainbow field 4, the secondary material area and a lead-out area 5» The clamp area 1 is a central area, so that the disc is equipped with sweetness for placing a rotating optical disc' and the above-mentioned conversion area For an information area secret B 埤, between 5 1330358 clamp area 1 and between the above-mentioned introduction area 4 and the above data area. After the disc manufacturing process is completed, B C A 3 is used to add information to the disc. The import area 4 is the important information required for disc playback, and the export area 5 is where the disc end signal is written. The lead-in area 4 is divided into a plurality of areas; a first protection area, a PIC, a second protection area, a second type of information, an OPC, a reserved area, and a first type of information. The first protected area is the protected area that prevents the BCA from overwriting the PIC. The P 1C zone is an area in which pre-recorded nicks are stored generally associated with the disc and various other information. The second protected area is a buffer for converting from the pre-recorded area to the rewritable area, and the first and second information areas are each used to store specific information related to the optical disc or application, such as control information. Figures 1B and 1C show a RUB (recording unit block), which is defined in the disc standard in question. A single RUB corresponding to a single ECC (Error Correction Code) consists of a start zone, a solid cluster, an end zone, and a guard zone, as shown in Figure 1B. If many RUBs, or continuous RUBs, are created a lot at a time to store real-time input data, for example, A/V data, a set of start zones, entities, and end zones are repeatedly created to the required number, and At the end, a protected area 'Gurar_3' is formed, as shown in Fig. 1C. As shown in Fig. 2A, the start zone is composed of a protected area 'Guar d_l' of a 1 0 0 channel bit and a preamble area 'PrA' of a 1660 channel bit. 5 copies of the 2 0 channel bit type are written in the defense area 'Guard_l' to indicate the header of the RUB, and the first synchronization data 'SyncJ' and the second synchronization data 'Sync_2' are written in the front In the area 'PrA'. In 1330358, Sync_l and Sync_2 have a length of 30 channels. Each sync data consists of a 24-bit sync body and a 6-bit sync ID. The synchronization IDs of the first and second synchronization data are each '000 1 00' (FS4) and '0 1 0 000, (FS6). As shown in Fig. 2B, the end zone is composed of a 540 channel protection block ‘Guard_2’ and a 564 channel bit content ‘PoA’. The PoA includes the third synchronization data 'Sync_3'. The third synchronization data is also composed of a 24-bit synchronization body and a 6-bit synchronization ID. Further, the synchronization ID of the third synchronization data is '000 00 1' (FS0). The protected area 'Guard_2' is created to prevent coverage between pre-recorded data and new data to be recorded. It also has a replica of 27 20-channel bit patterns for indicating the end 0 of the pre-recorded area called REB only. The user data is written in the physical cluster and it is used and written by the signal processor. The clock of the synchronized data synchronization in the initial area is restored to the original data. Figure 1D shows the detailed recording format of the physical cluster of BD_RE, where BD_RE is the location recorded by the 31 recording frames (frames #0~#30). The seven frame synchronization codes (FSs #0 to #6) which are different from each other are written in 31 recording frames in a predetermined unique order, as shown in Fig. 1D. The type and type of frame synchronization code shown in Figure 1E is written in a solid cluster. As shown in Fig. 1E, all seven frame synchronization codes are used and each frame synchronization code is composed of a 24-bit synchronization body and a 6-bit identification type. Each RUB corresponding to the foregoing single ECC block has a physical address 7 1330358 information, for example, an Address Unit Number (AUN), which is used to randomly access a random RUB written in a BD-RE. After being modulated and encoded with the A/V information, the entity address information is written in a physical cluster of a RUB. In addition, an AUN system is derived from a physical sector number (PSN), and in fact, the physical block code is not written in a BD-RE. Can only be written once and overwriteable discs (DVD-R, -RW, -RAM, +R, + RW), a link frame is generated before new data is recorded discontinuously from previous records After the previous recorded area. However, a CD-ROM such as a DVD-ROM and a video CD does not require any link frame to connect two data blocks because it contains the complete record information. Despite the differences between writable and CD-ready discs, a conventional disc player such as DVD-Player and DVD-ROM is required to equip additional entities and/or software for playing both types of discs. It goes without saying that a CD player capable of recording and playing a writable disc also needs to be equipped with additional physical and/or software to play CD-ROM and writable disc. At the same time, the standard for high-density CD-ROMs called ‘BD-ROM’ is also discussed with BD-RE. Incidentally, if the physical size of the bd-R〇M is the same as that of the BD-RE, it is advantageous for the optical disc player to apply the same playback operation to the two types of recording media. In addition, they need to be distinguished and their format compatibility is guaranteed. Therefore, there is a need to adjust these conflicts. However, suitable adjustment methods have not yet been provided.

[Embodiment] In order to make the present invention fully understandable, the preferred embodiments will now be described by the accompanying drawings. First, the connection area of the high-density recording medium constructed in accordance with the present invention and the data recording method associated with the connection area, also referred to as the data generation method, will be described in detail later. Hereinafter, the words "write", "record", and "form" have the same meaning for a read-only recording medium. In addition, a frame generated in the connection area is called a connection frame or a recording frame. (1) Architecture of a connection area - A high-density read-only recording medium, for example, a BD-ROM constructed in accordance with the present invention has an entity format (starting from a start area, a physical cluster) as described with reference to FIGS. 1 and 2 Regional and protected areas constitute). Further, Fig. 1 and Fig. 2 show a high-density rewritable recording medium. However, the areas of the BD-ROM that conform to the format of the rewritable recording medium element can be individually named under different names. The start region of the first embodiment of the present invention, as shown in Fig. 3A, consists of a protected area ^Guard-1' and a pre-arranged area 'PrA', which in turn contains two sync data. Each sync data consists of a 24-bit sync body and a 6-bit sync ID. When the synchronization IDs of the preamble synchronization data in the BD-RE are each '000 13 1330358 100' and {010 000', as shown in FIG. 2A, the front area of the BD-ROM constructed according to the present invention includes two Synchronous data, whose IDs are FS〇r〇00 001,) (Sync_3) and FS6 ('0 1 0 000,) (Sync_2). Further, the sync data 'Sync_3' is placed before the sync data 1γη<:_2'. Further, the rear area (PoA) of the BD-ROM end area constructed in accordance with the present invention, as shown in Fig. 3B, includes the synchronization data having the ID FS4 ('000 100') (Sync_l). There is a difference, that is, the synchronization data of the BD-RE with the synchronization ID FS0 ('000 001,) is written in the area after the BD-RE. In the BD-RE, if two RUBs are generated, a pair of start area and end area are also generated as shown in Fig. 1C. The pair start and end areas (corresponding to a connection area) contain three synchronization data records of 'Sync_l', 'Sync_2' and 'Sync_3'. Incidentally, the recording order in the bd-ROM is 'Sync_3'. ', lSync_2, and 'Sync_l,, in contrast to the order of BD-RE. Therefore, although the BD-ROM constructed in accordance with the present invention is similar to the physical recording format of the BD-RE, the writing order of the synchronized data in the connected area can be distinguished from the BD-RE. In addition, it is also possible to synchronize the arrangement of the data and easily determine whether the existing area is the connection area of the BD-ROM. In the above embodiment, the 'starting area, the ending area, and the protected area 'Guard-3' may contain information similar to the record of the corresponding area on the BD-RE. The structure of the BD-ROΜ connection region can be defined differently as shown in Fig. 4 which discloses the second embodiment of the present invention. As shown in Fig. 4, in 14 1330358 and in the case of BD-RE, the dissimilar domain and the end region of 27 60 bits constitute an example of a BD-ROM, and two of the same size (1932 channel bits) are known. The frame constitutes a starting area of a 104-bit unit of a single connection area. The two connection trusses are </ br> in the same architecture and any frame consists of 3 70 70 frame synchronization codes, 9 octet entity addresses, i "bytes for data and 32-bit parity Forming the position. The U4 byte user data can include a variety of additional resources such as anti-piracy information (to prevent illegal copying such as recording movies on BD-ROM to other media), control information (for servo operation) use). Fig. 4B shows a third embodiment of the present invention. The connection area of the third implementation is composed of two equal-sized (1 932 channel bits) connection frames, and each frame is composed of a 3-inch channel bit frame synchronization code, a tuple entity location, and a 1 4 6-bit tuple. User data consists of. The difference from the embodiment of Figure 4B of Figure 4A is that there is no parity bit. Useful information can be written to the 146-bit user resource. The useful information is anti-piracy information (to prevent illegal copying of movies recorded on a BD-ROM to other media), or control (for servo control operations). Figure 4C shows a fourth embodiment of the present invention. The connection area of the fourth implementation is composed of two equal-sized (1 193 channel bits) connection frames, and each frame is composed of a 30-channel bit frame synchronization code-byte user data. Compared with the single channel user information in Figure 4A's 4C picture frame, the one in the service control case is located in the first empty space. The information is on the shelf. • 155 Real 15 1330358 The difference between the examples is that there is no entity. Address and parity. This embodiment also differs from Figure 4B because there is no physical address. Fig. 4D is a view showing a fifth embodiment of the present invention. The connection area on the fifth embodiment is composed of a 30-channel bit front frame synchronization code, a connection portion of 3714 channel bits, two 30-channel bit rear synchronization codes, and two copies of 40 and 20 channel bit lengths, respectively. The module is composed of. The 3714 channel bit connection is made up of three connection frames and 4-bit padding data. A connection area can have any possible architecture that is different from the above. The data is written to the physical cluster A in the format of the ECC block, and the above seven frame synchronization codes FS0 to FS6 are usually used for the ECC block. At least one of the two connection frames as shown in Fig. 4A uses the new frame synchronization code 'FS η' and its synchronization ID is different from the above seven frame synchronization codes. Synchronization ID of new-frame synchronization code 4FS Ν' is '1〇〇101' (FS7), '101 〇l〇' (FS8), '〇1〇i〇i, (FS9), '101 OOI' (FSIO ), as shown in Figure 5. The selection of all four synchronization codes satisfies the conversion restrictions specific to BD-RE, that is, the bit module cannot be shorter than 2 bits. In the recording embodiment of Fig. 4A, the frame synchronization code FS0 is written in the first connection frame, and the frame synchronization code 'FS η' is in the second connection frame. In addition, the data recorded in a BD-RE must satisfy the "Run-Limited Transition (RMTR)" limitation of the 1 7ΡΡ (Parity Check Reserved) adjustment. This limitation is the 16 1330358 material recording standard defined by BD-RE. The prohibition of RMTR (to ensure stable detection of RF signals) is a minimum execution length of 2T, which is 4 〇 1, or ‘ 1 〇, which cannot be repeated more than six times in succession. Therefore, it tends to use a frame synchronization code with a small switching frequency, that is, '100 101, (FS7) or '101 001' (FS10) in the new frame synchronization code_to achieve a bit conversion that satisfies the limit. The use of the frame synchronization code will be explained in detail with reference to Fig. 6A. The first case shown in Fig. 6A is the first embodiment of the present invention. In the embodiment, the recording frames of the two 193 channel bits are recorded in a connection area, and each recording frame is composed of a frame synchronization code, a physical address, user data, and parity bits. At least one of the two record frames contains the newly defined frame synchronization code 'FS η,. For example, 'frame synchronization code' FS 〇' and its identification module (id) are written as the first frame synchronization code, and the identification module is '〇1〇1〇1, M〇1 〇1〇, or The new frame synchronization code 'FS n' of '100 101' is written as the second frame synchronization code. When the synchronous recognition module is '〇1〇101, '101 010, or '1〇〇1〇1, the new frame synchronization code 'FS n' is used, the frame synchronization code 'FS n, followed by 9 The byte entity address has an unscrambled start data '〇〇, as shown in Figure 6. This is because it helps to meet the RMTR condition of the 17ΡΡ adjustment code. The definition of the i 7ρρ adjustment code is used for recording information on the bd-RE. For example, 'If the new frame synchronization code FS7 with the synchronization identification module '丨00丨〇1' is used, the subsequent physical address bit is '〇ι n 17 1330358 01 11', which is via the 7D The adjustment bit made by the 17PP adjustment table shown in the figure is ' 0 1 0 1 0 1 0 1 0 1 0 Γ, then the adjustment bit that finally contains the synchronization identification module constitutes '100 101 010 101 010 101', wherein The 2T module (a module with one zero between two adjacent) continues to appear 7 times. However, if the physical address includes '0 0 ' in its header, the example of the above physical address becomes '00 01 11 01 11', and its 17PP adjustment bit becomes '010 100 101 010 10Γ. Therefore, the final bit having the synchronous recognition module constitutes '100 101 010 100 101 010 101'. Among them, a 3 T and four 2 T modules appeared one after another. The second condition as shown in Fig. 6A is the second embodiment of the present invention. In this embodiment, a record frame of two 1932 channel bits is recorded in a connection area, and each record frame is composed of a frame synchronization code, a physical address, user data, and parity bits. At least one of the two recording frames includes a frame synchronization code FS10 ('101 001'), one of the newly defined frame synchronization codes 'F S η '. For example, the frame synchronization code F S 0 of the recognition module of £ 0 0 0 0 0 1 ' is written as the first frame synchronization code, and the new frame synchronization code FS10 is written as the second frame synchronization code. When the new frame synchronization code 'FS10' is used, the RMTR limit of the 17-inch adjustment code used for data recording on the BD-RE is automatically satisfied. Therefore, the subsequent physical address does not begin with ‘ 〇〇 ’. For example, if the new frame synchronization code FS10 whose identification module is Μ 0 1 0 0 被 is used, and the subsequent physical address bit is '〇1 11 01 11', it passes the 17ΡΡ shown in the 7D figure. The adjustment bit 18 1330358 made by the adjustment table is ' 0 1 0 1 0 1 0 1 0 1 0 Γ, then the adjustment bit that finally contains the synchronization recognition module constitutes '101 001 010 101 010 101', where a 2Τ appears , a 3T and 6 2T modes. The third condition as shown in Fig. 6B is the third embodiment of the present invention. In this embodiment, two recording frames of 1 193 channel bits are recorded in a connection area, and each record frame is composed of a frame synchronization code, a physical address, user data, and parity bits. Composition. Both record frames contain the newly defined frame synchronization code 'FS η'. For example, the first and second frame synchronization codes utilize one of the following new frame synchronization codes, namely FS7 ('010 101,), FS8 ('101 010'), and FS9 ('100 101,). When the new frame synchronization code FS7, FS8 or FS9 is used, the 9-bit entity address after the frame synchronization code FS7, FS8 or FS9 has the unscrambled start data '〇〇', as shown in Figure 6A. Show. All of the above are for the RMTR limitation that better satisfies the 17PP adjustment code used for data recording on the BD-RE. When the new frame synchronization code FS7 ('100 101') is used, it can be satisfied by writing the actual address space after the frame synchronization code with the data instead of '0 1 11 0 1 11 ' RMTR limit. The fourth condition as shown in Fig. 6B is the fourth embodiment of the present invention. In this embodiment, two recording frames of 1 193 channel bits are recorded in a connection area, and each record frame is synchronized by a frame, a physical address 'user data and parity bits. Composition. Both record frames contain the new frame synchronization code FS10 ('10 001'). 19 1330358 When the new frame synchronization code ISIO' is used for two automatic RMTR restrictions that are defined on the BD-RE as data records. Therefore, each frame synchronization code begins with '0 0 '. If the newly defined frame synchronization daima 'FS η' is used if an existing area is in a connection area, it can be judged because the new frame synchronization code is different from the entity plex i. For example, when the frame synchronization code is combined Used to judge the time, because the combination of a frame synchronization code is composed of 'FS η' and FS4, each is written in the previous real 29 and the 31st recording frame (recording frames #28 to #30) ) is FSn-FS4 or FSn-FS2, which is obviously different from the combination generated by the frame synchronization code of the write set. Whether it is in a current area is based on the combination of frame synchronization codes. The seven scenarios described above are summarized below. If the appropriate restrictions are applied to the material to be written to a frame, then any other four frame synchronization codes can be, for example, if one is written after the frame synchronization code if the address of the entity always has a one-digit '00' Head, the code FS8 and FS9 can be used without hindrance. In the special case where a physical address is not written, the group, for example ' 4 0 8 h ' ( 0 0 0 0 1 0 〇〇) is not exactly written in the frame with scrambling, adjusted by 1VPP from 508h' When the data frame is in place, !) 1 The physical address of the 7PP adjustment code is not in the above situation, and the user is easily and accurately. The existing area ~~ The FS4 and FS2 of the body cluster in the connection area are changed into a solid cluster. The area is used after the exact code is synchronized. The address of the entity This frame is synchronized. If a bit step code is followed by the element chain '000 100 20 1330358 100 100' is placed after the frame synchronization code, then any four new frame synchronization codes FS7-FS 1 can be used. 0, without having to consider the RMTR constraint. The framework synchronization code is used to write one of the four new frame synchronization codes to one of the two connection frames when a known frame synchronization code FS0-FS6 is in a connection frame. Needless to say, this new framework synchronization code can only be used in the two connection frames as shown in the case of Cases 3 and 4 of Figure 6B. If at least one selected from the new frame synchronization code 'FS η' is used to connect the frame, when the recorded material is played from a BD-ROM, the optical disk player (as shown in FIG. 9 is composed of an optical pickup) 11. A VDP system 12 and a D/A converter 13 are configured to quickly know whether the currently read frame is within the connection area or a data section (solid cluster). In a BD-RE, 31 recording frames each include seven different frame synchronization codes. However, the seven frame synchronization codes are not sufficient to clearly define the 31 record frames, so the frame synchronization code in the previous record frame is used to identify an existing record frame and a frame synchronization code in the existing frame. In other words, the record frame N can be identified by the continuous sync code of its own frame sync code and the frame sync code in the previous record frame N-1, N-2, and/or N-3. That is, although one or two previous synchronization codes N -1 and / or N - 2 are not detected, the last detected N - 3 can be used together with its synchronization code and the record frame N Identification. For example, assuming that the existing recording frame is the eighth, that is, the recording frame #7, its frame synchronization code is F S 1 shown in the first D picture. 21 1330358 However, the frame synchronization code F S1 is also written in frames #1, #23 and 24, so the existing frame is identified by the previously detected frame synchronization code. And the current framework synchronization code F S 1 and the previously detected framework synchronization code FS4, FS1, and/or? 83 (in frames #6, #5, and #4, respectively) can recognize that the existing frame is #7.

如果FS0和FS7之框架同步代碼如第7A圖所示般被 使用，在具有框架同步代碼 FS0的框架#0之前的框架 Ν-1、Ν-2和N-3之框架同步代碼，依次是FS7、FS0和 FS2，如case (1)所示。框架#0與一 RUB的第一個位址單 元相對應。如case (2)所示，在第二列之框架#0前之三個 框架依序為框架同步代碼FS2，FS4和FS4。框架#0與一 RUB的中間位址單元相對應。如case (3)所示，框架# 1前 的三個框架之框架同步代碼依序為FSO，FS7/FS2和FS4。 因此，框架# 1與第一個位址單元或者一 RUB的中間單元 相對應。此外，在框架#2之前的三個框架之框架同步代碼 22 1330358 依序是 FS 1，FS0 和 FS7 / FS2，如 case (4、叱 _ , 、J所示e所以框 架#2係對應於一 RUB之第一或者中間單元。 如第7A圖的‘A，記號之情況所述，二框架#〇俱與一 RUB之中間位址單元相對應，而依據本發明之創新設計， 框架#3 1(第一個連接框架）具有與先前的框架相同之框架 同步代碼序列。因此，將難於偵知連接區域的開始，而採 納這對FS0與FS7將不是一個適當的解決辦法。 下例中，以第7B圖所示之FS7作為闡釋之示例。如 第7B圖之case (1)所示，框架#0之前的框架同步代碼依If the frame synchronization codes of FS0 and FS7 are used as shown in Fig. 7A, the frame synchronization codes of the frames Ν-1, Ν-2, and N-3 before the frame #0 having the frame synchronization code FS0 are FS7 in order. , FS0 and FS2, as shown in case (1). Frame #0 corresponds to the first address unit of a RUB. As shown in case (2), the three frames in front of frame #0 in the second column are frame synchronization codes FS2, FS4 and FS4. Frame #0 corresponds to an intermediate address unit of a RUB. As shown in case (3), the framework synchronization code of the three frameworks before Frame #1 is FSO, FS7/FS2 and FS4. Therefore, frame #1 corresponds to the first address unit or an intermediate unit of a RUB. In addition, the frame synchronization code 22 1330358 of the three frames before frame #2 is FS 1, FS0 and FS7 / FS2 in sequence, as in case (4, 叱_, , J, e, so frame #2 corresponds to one The first or intermediate unit of the RUB. As described in the case of 'A, the symbol of Figure 7A, the two frames correspond to the intermediate address unit of a RUB, and the innovative design according to the present invention, frame #3 1 (The first connection frame) has the same frame synchronization code sequence as the previous frame. Therefore, it will be difficult to detect the start of the connection area, and adopting this pair of FS0 and FS7 will not be an appropriate solution. In the following example, The FS7 shown in Fig. 7B is taken as an example of explanation. As shown in case (1) of Fig. 7B, the frame synchronization code before frame #0 depends on

然而，如第7 B圖‘ B，標示之例所示。依據本發明創新 之設計第一連接框架（框架#31)和第二連接框架（#32)在 框框架N及框架N_3中具有相同的框架同步代碼順序，而 其定義連接區域時可能產生問題。然而，如因兩連接框架 使用兩F S 7，而有新定義的框架同步代碼f S 7。在偵測一 連接區域時，FS7-FS7的這個情況所導致之問題，並不比 第7A圖的FS〇_FS7的情況來得嚴重。 第7C圖所示為FS7和FS8被實施之情況。如case(l) 所不’在框架#〇之前的框架同步代碼依序是FS8/FS2 ， 23 1330358 前’利用FS7和 即，任何框架之 因此，在偵測相 它不會產生問題 FS7 / FS4和FS2 / FS4。而框架#〇是RUB的第—或者 位址單元。如case (2)所示，在框架#1之前的框架同 碼依序是FSO ’ FS8 / FS2和FS7 /

如第4A圖所示之連接框架結構，在第圖所示連 接區域之每-個記錄框架中寫入一個實體位址，計有三種 25 1330358 情況。第一種情況，在兩個連接框架中皆寫入該框架之後 最接近之實體叢集#k+ 1的 AUN »而第二種情況係寫入該 框架之前最接近之實體叢集#k2 AUN。 第三種情況，第一連接框架之前最接近之實體叢集#k 的AUN被寫入該第一個連接框架，而第二連接框架之後最 接近之實體叢集#1<+1的AUN被寫入該第二個連接框架。 實體位址（由 4位元組的位址，保留之 1位元組和 4 位元組的奇偶校驗位所組成，如第1 1 A圖所示）被RS(9,5，5) 編碼後，具有錯誤恢復能力，供一 BD-RE所用。使一個位 址具有錯誤恢復能力之過程將詳述於後。 因此，一光碟播放機其由一個光學讀寫頭 11、一個 VDP系統 12、和D/A轉換器13所組成，如第9圖所示， 當一 BD-ROM被置於其中時，能夠更精確地偵知在該 BD-ROM之第一和第二連接框架（記錄框架#k+l、#k + 2)中 之一使用者資料和實體位址。尤其是如果使用者資料包含 反-侵犯版權或伺服-控制之有用資訊，以光碟播放進行對 有用之資訊合適之操作。 第4D圖中所示的連接框架結構中，在第10B圖所示 連接區域之三個記錄框架之任一中寫入一個實體位址，計 有二種情況。第一種情況，在三個連接框架中寫入該框架 之後最接近之實體叢集1的 AUN。而第二種情況係寫 入該框架前面最接近之實體叢集之AUN。 實體位址（由 4位元組的位址，保留之 1位元組和 4 位元組的奇偶校驗位所組成，如第1 1 A圖所示）被RS(9,5,5) 26 1330358 編碼後，具有錯誤恢復能力，供一 BD-RE所用。使一個位 址具有錯誤恢復能力之過程將詳述於後。 因此，一光碟播放機其由一個光學讀寫頭 11、一個 VDP系統 12、和D/A轉換器13所組成，如第9圖所示， 當一 BD-ROM被置於其中時，能夠更精確地偵知在該 BD-ROM之連續三個連接框架（記錄框架#k+l、#k + 2、K + 3) 中之一使用者資料和實體位址。尤其是如果使用者資料包 含反-侵犯版權或伺服-控制之有用資訊，以光碟播放進行 對有用之資訊合適之操作。 第1 0 C圖所示為本發明另一實施例，其在記錄框架中 寫入一位址。這些連接框架（記錄框架#k+l、#k + 2 )之任 一包含一個 9位元組的實體位址，又該實體位址包含 4 位元組的真實位址。4位元組的真實位址可能具有相同數 值之16個A UNs#0〜#15,又其寫入於連接框架之前或之後 的實體叢集之中。 一寫入於第一連接框架前之實體叢集的4位元組真實 位址係由一 2 7位元位址、一用以標示其在實體位址中順序 的4位元序列碼（0 0 0 0〜1 1 1 1)和 1位元固定之數值4 0 ’所組 成，如第10C圖所示。所有寫入於前面的實體叢集之27 位元位址具有相同數值。 另一寫入於第二連接框架後之實體叢集的4位元組真 實位址係由一 2 7位元位址、一用以標示其在實體位址中順 序的4位元序列碼（0 0 0 0〜1 1 1 1)和1位元固定之數值‘ 0 ’所組 成，如第10C圖所示。所有寫入於其後的實體叢集之27 27 1330358 位元位址具有相同數值。 如前所述，第一連接框架之4位元組的真實位址 一位址，又其寫入於位於之前的實體位址中。例如， 連接框架之 4位元組的真實位址具有最接近之第1 AUN (AUN#15)的位址值，又該AUN由27位元和‘1: 所組成，如第10C圖所示。這種情況下，被寫入該 連接框架之該五位元‘11110’的最後一位元‘0’可以被' 取代，藉以標示一實體位址係被寫入一連接區域，而 實體叢集。 此外，第二連接框架之4位元組的真實位址包括 址，又其寫入於位於之前的實體位址中。例如，第一 框架之 4位元組的真實位址具有最接近之第 1個 (AUN#0)的位址值，又該AUN由27位元和‘00000’所k 如第10C圖所示。這種情況下，被寫入該第一連接 之該五位元‘00000 ’的最後一位元‘0’可以被‘1’所取代 以標示一實體位址係被寫入一連接區域，而非一實體1

位址被用作一初始值，以載入轉換登錄器。 如第13圖所示，4位元組位址（Add#0〜#31)之一部 被平行載入一擾頻器之16位元轉換登錄器101’中，該 頻器亦適用於BD-RE之記錄，而後，在位元轉換過程中 依序輸出155個8位元擾頻位元組（S0~S 154)。 該連續之155個擾頻位元組 （S0~S154)被.一「互斥 閘」102'以連續之155個使用者位元組 （D0〜D 154)「互

之 入 料 體 分 擾 ί 或 斥 生 部 者 用 記 值 31 1330358 (例如，‘00h’）填充使用者資料空間，如第14 A圖所示。一 系列這樣的填充值稱作填充資料。 如果填滿相同的資料於整個使用者資料空間，一個 BD-ROM的製程便能簡化得更多。順帶一提，如果鄰近磁 轨具有相同的位元模組，則可能發生串音。因此，如填充 資料之另一實施例所示，某些值（例如，、 ‘Olh’、 ‘10h’、 ‘llh’、 ‘FFh’、 ‘ A Ah’、等等）依序被寫入使用 者資料空間中，如第14B圖所示，以減少串音發生之可能 性。 填充資料記錄之實施例中’一 B D - R Ο Μ中部署之每一 連接框架的記錄框架中記錄了不同值的填充資料，它減少 鄰近磁軌間形成相同的記錄模組之可能性。因而大大地減 少串音發生之可能性。 一個BD-ROM的連接區域形成兩個記錄框架以確保與 BD-RE之播放相容性。依據本發明的另一個實施例，可以 利用任意幾個相異值填充使用者資料空間，例如，‘ 〇 〇 ’、 ‘01’、 ‘11’，其如第14C圖所示交替出現。 第1 4 C圖之填充資料記錄實施例中，一連接區域之使 用者資料空間中有相同的資料，而鄰近連接區域有不同之 填充資料。 在該實施例中，鄰近磁執之間形成相同的記錄模組的 可能性很小，因此，與第14 Α圖實施例相較’串音發生之 可能性降低了。該實施例之B D - R〇Μ的製程比第1 4 B圖的 那個更簡單。 32 1330358 此外，如果一值（例如，’0 0 h ’）在以改變每個連接區域 之一實體位址擾頻之後，填充整個使用者資料空間，也能 夠大為消除串音。 在擾頻之後，‘〇〇h’填充該等使用者資料空間之情況 下，如果一未擾頻之‘〇8h’被置於每一使用者資料空間之最 前面，則能利用任何上述之新框架同步代碼而無需顧慮前 文所述之17PP調整所規定之RMTR限制。 (5)ECC區塊之建構 如果使用者資料空間中寫入了有用且重要之資訊，其 以通道編碼進行編碼以確保它的可靠性，RS(62,30,3 3)和 (2 4 8,2 1 6，3 3)編碼系統被用作通道編碼方法。而那些編碼系 統也被設定為替一個BD_ROM的實體叢集中寫入之使用者 資料編碼。 第1 5 A圖所示為一記錄之實施例，其中資料記錄於第 4D圖所建構之連接區域。為如第15A圖所示般記錄有用 資料，首先RS(62,3 0,3 3)系統對30位元組之有用資料進行 編碼，它創造3 2位元組的奇偶校驗位。 . · · 為供操作之用，一記憶體依序儲存輸入之資料以組織 一個3 0 X 3 0 9資料區塊。當組織一個3 0 X 3 0 9資料區塊時， 依序掃描每個縱列（1 5 1)。RS(62,3 0,33 )編碼系統產生了 32 位元組的奇偶校驗位，所有操作掃描該欄並向那裡附加。 最後，一 6 2位元組的資料序列被架構起來。 可以對包含奇偶校驗位的每一個 62位元組進行擾 頻。如果進行擾頻，可以把一個實體位址之一部分用作如 33 1330358 前所述之一個擾頻金鎗。 其次，在由上述過程組成之62位元組之前增加一個 9 位元組的實體位址。該9位元組之實體位址可以在此由一 個真實實體位址和奇偶校驗位組成。例如’ 9位元組之實 體位址可以由一個4位元組之真實位址、保留的1位元組， 和4位元組的奇偶校驗位所組成。 此外，向包含實體位址之71位元組中添加 145位元 組的填充資料，而後RS(248,2 1 6,3 3)系統將其編碼。從而 增加 3 2位元組的奇偶校驗位。最後，被加入之1 4 5位元 組之填充資料被移除以產生欲寫入連接區域之103位元組 的資料單元。 對下一 30位元組之有用資料重複進行上述操作以產 生連續之103位元組的資料單元。在製造三個單元之後， 該三個單元之後加入4填充位元，而後總共2 4 6 7個位元被 施以1 7PP調整。在1 7PP調整之後，該2467位元者被擴 展為3714個通道位元。該被調整之3714位元者，和第二 個3 0通道位元框架同步代碼之前被置入3 0個通道位元之 第一框架同步代碼，一 40通道位元者重複了位元模组，重 複位元模組之第三個3 0通道位元框架同步代碼和另一 2 0 通道位元者依序附加至該調節之位元。以此產生之 3 8 6 4 個通道位元被寫入一連接區域。 如果有用之資料太小而不足以填充上述之一單一連接 區域，則有用資料之片斷中添加了填充資料以達到3 0個位 元組。例如，欲寫入3位元組之有用資料，則每一連接區 34 1330358 域三位元組中的一個不可避免地必須構成一單一資料單 元。因此，如第15C圖所示，一個30x309資料區塊中， 一個3 0 9位元組之直行攔位僅僅寫入一橫列而其他2 9橫列 全部被填充入填充資料。它意味著每個直行欄位中，2 9位 元組之填充資料被加入 1位元組之有用資料。最後， RS(62,30,33)編碼系統被用於該填充加入之30位元組中的 每一個縱列以向該處附加 3 2位元組的奇偶校驗位。 為恢復之前寫入連接區域之有用資料，一個解譯過 程，可實施即如上所述解釋之寫入過程的相反順序。 如果兩相同之框架構成如第4B圖所示之單一連接區 域，可用第4A圖所示之114位元組的有用資料和32位元 組的奇偶校驗位填充連接框架的使用者資料空間。第4 A 圖記錄實施例中，把第4 B圖或者第4 C圖描述之一個不同 方法用於通道編碼以確保資料之可靠性。該不同之方法詳 見第16圖。 首先收集有用之資料達2 04 8個位元組（S 1)。把4位 元組E D C (錯誤偵測碼）附加給以該2 0 4 8個收集到之位元組 組成的一個有用資料區塊（S2)。將包含EDC之2052個位 元組分成十八個 1 1 4位元組的資料單元（S 3 )。對第一個資 料單元進行擾頻（S4)，而9位元組的實體位址被加在它的 前頭（S 5)。9 3位元組之填充資料被加入於包含實體位址之 123位元組的資料單元中並被 RS (24 8，2 1 6,33)系統編碼， 以此把 3 2位元組的奇偶校驗位附加給資料單元。將該9 3 個增加的位元組移除以產生 155 位元組的框架資料 35 1330358 (S 6)，又該資料隨後被1 7PP調整。最後，框架資料前面加 入上述之30通道位元框架同步代碼以完成1932個通道位 元之連接框架（S7)。 上述之一系列過程 （S 4 - S 7)應用於其後被切割之 1 1 4 位元組的資料單元以製造另一個連接框架。由此產生之兩 連接框架被寫入一連接區域，最後形成了第4A圖所示之 結構。 當對每一個1 1 4位元組的資料單元都進行上述過程之 擾頻時，將一個實體位址如上所述般用於擾頻。將相同的 或者不同的實體位址（其寫入於位在連接區域之前或之後 的 RUB)被用於連接區域的第一和第二連接框架。如果使 用於不同位址，第一連接框架使用一連接框架之前寫入之 一個位址，而第二連接框架使用該連接框架之後寫入之另 一個位址。 — 如前所述，每一個連接框架中寫入之實體位址可以由 4位元組的真實位址，保留之1位元組，和4位元組的奇 偶校驗位組成。這種情況下，藉由應用通道編碼系統 RS(9,5,5)至該5位元組以產生4位元組的奇偶校驗位。 此外，該4位元組的真實位址由用於連接區域中分辯 個別實體位址之5位元位址標識符和2 7位元的位址所組 成。 可以將一對‘ 0 0 0 0 0/ 1 1 1 1 0 ’或‘ 0 0 0 0 1

FS7/FS4. And FS2/FS4. The frame #〇 is the first address unit or intermediate unit of the RUB. As shown in case (2), the frame synchronization code before frame #1 is FS0, FS7/FS2. And FS7/FS4. Frame #1 is the first or intermediate unit of a RUB. In addition, as shown in case (3), the frame synchronization code before frame #2 is FS1, FS0. And FS2. Frame #2 is also the first or intermediate unit of rub. However, as shown in Figure 7B ‘B, the illustration is shown. According to the inventive innovation of the present invention, the first connection frame (frame #31) and the second connection frame (#32) have the same frame synchronization code sequence in the frame frame N and the frame N_3, and a problem may arise in defining the connection area. However, if the two connection frames use two F S 7, there is a newly defined frame synchronization code f S 7. When detecting a connection area, the problem caused by this situation of FS7-FS7 is not more serious than the case of FS〇_FS7 in Figure 7A. Figure 7C shows the implementation of FS7 and FS8. For example, case(l) does not 'frame synchronization code before frame#〇 is FS8/FS2, 23 1330358 before 'utilize FS7 and ie, any frame, therefore, it will not cause problems in detecting phase FS7 / FS4 And FS2 / FS4. The frame #〇 is the first or the address unit of the RUB. As shown in case (2), the frames in the same order before frame #1 are FSO s FS8 / FS2 and FS7 / FS4. The frame #丨 is the first or intermediate unit. In addition, as shown in case (3), the frame synchronization before frame #2 is FS1' FS0 and FS7 / FS2e, and frame #2 is also an intermediate unit. As shown in Fig. 7C, in any frame representing a different previous frame synchronization code sequence, the previous frame synchronization code sequence is only _, when one of the 7A and 7B diagrams is connected, thus, FS7 and FS8 The preferred embodiment is constructed in accordance with the present invention. In addition, the framework synchronization codes FS7 and FS8 generally satisfy the RMTR constraint. Figure 8 is a flow chart of a method according to an embodiment of the present invention for playing a recording medium. If one of the connection areas BD_constructed according to the present invention is loaded (S81)', the tube sfl for playing control first in the BD-ROM is read into the suffix (S82). Since in general the management information is written into a lead-in area, it is read by a read/write head in an initial stage. Then, the main asset playback is started under the control of the control unit (S83). During playback, it is checked whether or not the frame is synchronized (S84). If the Detector determines whether the synchronization code to be detected is a synchronization code written in the main material area (S85). If the comparison-light intermediate step RUB code before the FS8 is opposite to the splicing area as above, the code for the ROM resource has been preliminarily required to be recorded 24 1330358 recording/playback component stored in the synchronization code FS0~FS6 and The well-known synchronization code can be discriminated. Playback continues if it determines that the detected sync code is the write L-step code (FS0-FS6) (S86) in the main data area. However, 'such as an IJ' determines that the detected synchronization code does not belong to the synchronous generation (FS0~FS6)' means that it is the newly defined synchronization code FS7 or FS8' an existing location is associated with a connection area (S 8 7), and then check again whether it is in the first connection frame or in the second connection frame (S 88). If in the first connection frame, the data after its frame synchronization code is scrambled (S89). Otherwise, the existing location is associated with the second connection frame, and then the data just after its frame synchronization code is scrambled (S90). Therefore, a disc player is composed of an optical pickup 11, a VDP system 12' and a D/A converter 13, as shown in Fig. 9, when a BD-ROM is placed therein, One of the user data and the physical address in the first and second connection frames (recording frame #k+1 ' #k + 2) of the BD-ROM is accurately detected. In particular, if the user profile contains useful information about anti-infringement or servo-control, use CD-ROM playback to perform appropriate operations on useful information. As described above, whether an existing location (on which an optical pickup is located) is located within a connection area or a main data area, and can be compared by detecting and synchronizing code with a newly defined frame. know. (2) Physical address As shown in the connection frame structure shown in Fig. 4A, one physical address is written in each of the recording frames of the connection area shown in the figure, and there are three cases of 25 1330358. In the first case, the AUN of the closest physical cluster #k+ 1 after the frame is written in both connection frames and the second case is the closest physical cluster #k2 AUN before the frame. In the third case, the AUN of the closest physical cluster #k before the first connection frame is written to the first connection frame, and the AUN closest to the physical cluster #1<+1 after the second connection frame is written. The second connection frame. The physical address (composed of a 4-bit address, a reserved 1-byte and a 4-bit parity, as shown in Figure 1 A) is RS (9, 5, 5) After encoding, it has error recovery capability for use by a BD-RE. The process of making an address error resilience will be detailed later. Therefore, a disc player is composed of an optical pickup 11, a VDP system 12, and a D/A converter 13, as shown in Fig. 9, when a BD-ROM is placed therein, One of the user data and the physical address in the first and second connection frames (record frames #k+1, #k+2) of the BD-ROM is accurately detected. In particular, if the user profile contains useful information about anti-infringement or servo-control, use CD-ROM playback to perform appropriate operations on useful information. In the connection frame structure shown in Fig. 4D, one physical address is written in any one of the three recording frames of the connection area shown in Fig. 10B, and there are two cases. In the first case, the AUN closest to the physical cluster 1 after the frame is written in the three connection frames. The second case is written to the AUN of the closest physical cluster in front of the framework. The physical address (composed of a 4-bit address, a reserved 1-byte and a 4-bit parity, as shown in Figure 1 A) is RS (9, 5, 5) 26 1330358 After encoding, it has error recovery capability for use by a BD-RE. The process of making an address error resilience will be detailed later. Therefore, a disc player is composed of an optical pickup 11, a VDP system 12, and a D/A converter 13, as shown in Fig. 9, when a BD-ROM is placed therein, Accurately detect one of the user data and the physical address in the three consecutive connection frames (record frames #k+l, #k + 2, K + 3) of the BD-ROM. In particular, if the user profile contains useful information for anti-infringement or servo-control, use CD-ROM playback to perform appropriate operations on useful information. Figure 10C shows another embodiment of the present invention in which a single address is written in the recording frame. Any of these connection frames (record frames #k+l, #k + 2) contain a 9-bit entity address, and the entity address contains a 4-bit real address. The 4-bit real address may have 16 A UNs #0~#15 of the same value, which is written in the physical cluster before or after the connection frame. A 4-bit real address of a physical cluster written before the first connection frame is a 27-bit address, and a 4-bit sequence code (0 0) indicating its order in the physical address. 0 0~1 1 1 1) and 1 bit fixed value 4 0 ', as shown in Figure 10C. All 27-bit addresses written to the previous physical cluster have the same value. Another 4-bit real address of the physical cluster written after the second connection frame is a 27-bit address, and a 4-bit sequence code (0) indicating its order in the physical address (0) 0 0 0~1 1 1 1) and 1 bit fixed value ' 0 ', as shown in Figure 10C. The 27 27 1330358 bit address of all the physical clusters written after it has the same value. As mentioned before, the real address of the 4-bit tuple of the first connection frame is written to the previous physical address. For example, the real address of the 4-byte of the connection frame has the address value closest to the 1st AUN (AUN#15), and the AUN consists of 27 bits and '1: as shown in Figure 10C. . In this case, the last bit '0' of the five-bit '11110' written to the connection frame can be replaced by ', thereby indicating that a physical address is written to a connection area and a physical cluster. In addition, the real address of the 4-byte of the second connection frame includes the address, which is written in the previous physical address. For example, the real address of the 4-byte of the first frame has the address value closest to the first (AUN#0), and the AUN is represented by 27 bits and '00000' as shown in FIG. 10C. . In this case, the last bit '0' of the five-bit '00000' written to the first connection can be replaced by '1' to indicate that a physical address is written to a connection area, and The last five of the 4-bit real address of the non-entity 1 written to the first connection frame may be '〇〇〇〇〇', and the last five bits of the true 4-bit written to the second connection frame may It is 1 11 1 1 0 '. In addition, an address written into a physical cluster may be written in the second connection area, and the entity cluster is one of the physical clusters before and after the connection area, as described above with reference to FIG. . (3) Scrambling The flow of the connection frame of the structure shown in Fig. 4A includes the first six 110s, the first one is not connected to the AUN, the frame, and the I set. The bit address is one or or square 28 1330358. The process of the connection frame architecture includes scrambling 1 〇 and adding the user frequency of the 1 to 4 1 byte to the user data to be scrambled by 9 bytes to make its DSV (digital sum value) Adding a 9-bit entity address zero before the user data approaching zero. The adder 20 increments the 32-bit tuple synchronization code from the scrambler 10 and the user of the added address by the 20-bit bit frame synchronization code located behind the user data of the added address. Thus, a recording frame is constructed, which contains 114 bytes of user data, and the user data of the group 1 is scrambled by a 9-bit physical address to disturb the user data, and can be used except one 9 Information outside the physical address. Figure 11 is a block diagram of a connection frame for the frame structure shown in Figure 4D. The connection framework is structured by the process package 10· and the add-on device 20·. The scrambler 1 (ie with a 9-bit address to the 6-byte user data (eg anti-infringement; to scramble, so that its DSV (digital sum) approaches zero) And adding a physical address of the 9-byte group before the user data. The adder 20 self-scrambler 10·adds the parity of the 32-bit tuple to the user data of the added address, thus forming a complete position The tuple's record frame, which includes user data of a 5-byte entity frequency of 62 bytes. The scrambling aspect of the user data can use information other than a 9-bit physical address. The construction includes the frame synchronization code, and the 9-bit tuple is 20. The perturbation address is completely recorded in the 12-bit frequency of the scrambling data. The additional scrambling entity bit information of the bit group is pre-scrambled. The check digit & 103 address scrambling entity bit 29 1330358 address, the 1 1 4 byte user data, and the 3 2 byte location connection framework, as shown in Figure 4A, can be constructed A physical address with a frame synchronization code, 9 bytes, 1 byte and 4 The parity of the byte, and the user data, as shown in Figure 4B or Figure 12A. The user data of the group can be scrambled and the 4-bit address can be used as a scrambling That is, in the scrambling process, a portion of the 4-bit entity bit (Add0~Add3 1) is used as an initial load value of a 16-bit recorder 101, as shown in FIG. 12B. After the initial load value is loaded in parallel in parallel, each bit has a scrambling byte. Because in the embodiment of Fig. 9, the length of the user data group, each 146 conversions are parallelized in the conversion register 101. After entering part of the address to be loaded due to the change of the connection area, 146 scrambling bytes (S 0~S 1 4 5) are created to repute or gate "1 0 2 to make. The 146 consecutive bits of the user data are known as "mutually exclusive." Thus, the contiguous group that was scrambled as before is written into the connection frame. In addition to the physical address, one part of the frame synchronization code module Some replicas of '1 0 ' can be used as scrambling keys to frequency users. In addition, one of the physical addresses is written in addition to the connection frame. One of them can be used, which is included in a physical cluster behind an existing connection box. In particular, among the 16 addresses, the closest parity connection frame contains the reserved bytes of the pair 1 4 6 The 32-bit conversion of the real real address of the byte is converted. The conversion output is a change of the address of the 1 4 6-bit entity. In parallel, it is "inter-l (D0 ~ D145) 1 4 6 Bits or bit data are used for scrambling, and an address of the existing frame 30 1330358 is used before the 16 address frame. A physical address to be written to a connection frame can be scrambled along with the user data written to it. In another embodiment of the invention, it is not possible to write a physical address in the interface as shown in Figure 4C. In this case, the physical address before or after the connection frame is used as a scramble key, that is, the initial load value of a store switch. Because in this embodiment, the user resource length is 155 bytes, and every 15 5 conversions, the same or different real addresses are used as an initial value to load the conversion register. As shown in Fig. 13, one of the 4-bit address (Add#0 to #31) is loaded in parallel into a 16-bit conversion register 101' of a scrambler, which is also applicable to BD. The -RE record, and then 155 8-bit scrambling bytes (S0~S 154) are sequentially output during the bit conversion process. The contiguous 155 scrambling bytes (S0~S154) are "interconnected" by a "mutually exclusive" gate 102' with 155 consecutive user bytes (D0~D 154). Therefore, 155 scrambled user data (DW~IV 154) are produced and they are written into the recording frame of a connected area. In addition to a physical address, some copies of the frame with the #.code module or bits '1 〇 ' can be used as a scramble key to scramble the usage data. (4) Filling data When the anti-infringement copyright or the useful data of the servo control is not written into the messenger data space, although the connection area of one BD-ROM forms two recording frames to ensure compatibility with the playback of the BD-RE, it is possible The user data space is filled with an arbitrary splicing of the incoming body or by the scribing unit 31 1330358 (eg, '00h'), as shown in FIG. 14A. A series of such fill values is called fill data. If the same data is filled in the entire user data space, a BD-ROM process can be simplified more. Incidentally, crosstalk may occur if adjacent tracks have the same bit module. Thus, as shown in another embodiment of the padding data, certain values (eg, 'Olh', '10h', 'llh', 'FFh', 'A Ah', etc.) are sequentially written for use. In the data space, as shown in Figure 14B, to reduce the possibility of crosstalk. Filling data of different values are recorded in the recording frame of each of the connection frames deployed in the embodiment of the padding data record, which reduces the possibility of forming the same recording module between adjacent tracks. This greatly reduces the possibility of crosstalk. The connection area of one BD-ROM forms two recording frames to ensure playback compatibility with the BD-RE. In accordance with another embodiment of the present invention, the user profile space can be populated with any of a number of distinct values, e.g., '〇 〇 ’, '01', '11', which alternate as shown in Figure 14C. In the embodiment of the padding data recording of Fig. 4C, the user data space of a connection area has the same data, and the adjacent connection area has different padding data. In this embodiment, the possibility of forming the same recording module between adjacent magnets is small, and therefore, the possibility of occurrence of crosstalk is lowered as compared with the 14th embodiment. The process of B D - R 该 of this embodiment is simpler than the one of Fig. 4B. 32 1330358 Furthermore, if a value (e.g., '0 0 h ') fills the entire user data space after scrambling the physical address of one of the connection areas, the crosstalk can be greatly eliminated. After the scrambling, if '〇〇h' fills the user data space, if an unscrambled '〇8h' is placed at the top of each user data space, any of the above can be utilized. The new framework synchronizes the code without having to worry about the RMTR limits specified in the 17PP adjustment described above. (5) Construction of ECC block If useful and important information is written in the user data space, it is coded with channel coding to ensure its reliability, RS (62, 30, 3 3) and (2 4 8 , 2 1 6, 3 3) The coding system is used as a channel coding method. Those encoding systems are also set to encode user data for a set of BD_ROM entities. Figure 15A shows an embodiment of a record in which the data is recorded in the connection area constructed in Figure 4D. To record useful data as shown in Figure 15A, the RS (62, 3 0, 3 3) system first encodes the useful data for the 30-bit tuple, which creates a 32-bit parity bit. • For operation, a memory stores the input data in order to organize a 30 0 3 0 9 data block. When a 30 0 3 0 9 data block is organized, each column (1 5 1) is scanned sequentially. The RS (62, 3 0, 33) encoding system produces a 32-bit tuple parity, and all operations scan the column and attach it there. Finally, a data sequence of 6.2 bytes is constructed. Each 62-bit tuple containing parity bits can be scrambled. If scrambling is performed, one of the physical addresses can be used as a scrambled gun as described in 33 1330358. Second, add a 9-bit entity address before the 62-bit tuple consisting of the above process. The physical address of the 9-bit tuple can here consist of a real entity address and a parity bit. For example, the physical address of a '9-byte' can consist of a 4-bit real address, a reserved 1-byte, and a 4-bit parity. In addition, a padding of 145 bytes is added to the 71-bit tuple containing the physical address, which is then encoded by the RS (248, 2 1 6, 3 3) system. This increases the parity of the 32-bit tuple. Finally, the padding data of the added 145 bytes is removed to generate a data unit of 103 bits to be written to the connection area. The above operation is repeated for the useful data of the next 30-tuple to generate a continuous 103-bit data unit. After the three cells were fabricated, the three cells were followed by 4 padding bins, and a total of 2 4 6 7 bins were then subjected to a 1 7 PP adjustment. After the 1 7PP adjustment, the 2467 bits were expanded to 3,714 channel bits. The adjusted 3714 bit, and the second 30 channel bit frame synchronization code are placed into the first frame synchronization code of the 30 channel bits, and the 40 channel bit repeats the bit module. The third 30 channel bit frame synchronization code and another 20 channel bit of the repeating bit module are sequentially added to the adjusted bit. The 3 8 6 channel bits thus generated are written into a connection area. If the useful data is too small to fill one of the above single connection areas, padding data is added to the piece of useful data to reach 30 bytes. For example, to write a useful piece of 3-byte, one of the three octets of each connection zone 34 1330358 must inevitably constitute a single data unit. Therefore, as shown in Fig. 15C, in a 30x309 data block, a straight block of a 309 byte is written into only one row and the other 209 ranks are all filled into the padding data. It means that in each of the straight-line fields, the padding data of the 29-bit group is added to the useful information of the 1-byte. Finally, an RS (62, 30, 33) encoding system is used to fill each of the added 30-bit bytes to add a 32-bit parity to the parity. To recover the useful information previously written to the connection area, an interpretation process can be performed in the reverse order of the write process as explained above. If the two identical frames form a single connection area as shown in Fig. 4B, the user data space of the connection frame can be filled with the useful data of 114 bytes shown in Fig. 4A and the parity bits of 32 bytes. In the fourth embodiment of the recording example, a different method described in Fig. 4B or Fig. 4C is used for channel coding to ensure the reliability of the data. See Figure 16 for a detailed description of the different methods. First collect useful information up to 2 04 8 bytes (S 1). A 4-byte E D C (error detection code) is attached to a useful data block (S2) composed of the 2 0 48 collected bytes. The 2052 bit elements of the EDC are grouped into eighteen 1 1 4 byte data units (S 3 ). The first data element is scrambled (S4), and the physical address of the 9-byte is added to its head (S 5). 9 3-bit padding data is added to the data unit containing the physical address of the 123-bit tuple and is encoded by the RS (24 8, 2 1, 6, 33) system, thereby taking the parity of the 32-bit tuple The check digit is appended to the data unit. The 93 additional bytes are removed to produce 155-bit frame data 35 1330358 (S 6), which is then adjusted by 1 7PP. Finally, the above-mentioned 30-channel bit frame synchronization code is added to the frame data to complete the connection frame of 1932 channel bits (S7). One of the above series of processes (S 4 - S 7) is applied to the data unit of the 1 1 4 byte that is subsequently cut to make another connection frame. The resulting two connection frames are written into a connection area, and finally the structure shown in Fig. 4A is formed. When scrambling the above process for each of the 1 1 4 byte data elements, a physical address is used for scrambling as described above. The same or different physical addresses (written in RUBs before or after the connection area) are used to connect the first and second connection frames of the area. If used for a different address, the first connection frame uses an address written before the connection frame, and the second connection frame uses another address written after the connection frame. – As mentioned earlier, the physical address written in each connection frame can consist of a 4-bit real address, a reserved 1-byte, and a 4-bit parity. In this case, the 4-bit tuple parity is generated by applying the channel coding system RS (9, 5, 5) to the 5-bit tuple. In addition, the real address of the 4-byte is composed of a 5-bit address identifier and a 27-bit address for distinguishing individual entity addresses in the connection area. A pair of '0 0 0 0 0 / 1 1 1 1 0 ' or ' 0 0 0 0 1 / 1 1 1 1 1 ' can be used as the address identifier. If the former (or the latter) is used, '〇〇〇〇〇' (or '〇〇〇〇厂') is inserted into a physical address in a connection frame, and [11110' (or 36 1330358 '11111') is inserted. In another connection frame. In the above, the new frame synchronization code 'F S η ' (different from the synchronization codes 'FS0~FS6' used for the data truss written to the physical cluster) can be used for the connection frame. If a new framework synchronization code different from the synchronization code of the data frame is used, the data written in the real cluster is translated into a password using the framework synchronization code in a connection framework to protect the digital content recorded on a BD-ROM from the digital content. Illegal copying. Although the data content recorded on a BD-ROM with such a translated password is copied to a rewritable optical disc, for example, BD-RE, the new frame synchronization code 'FS η in the connection frame is not copied to a BD- Above the RE, and β is not generated during the BD-RE recording, that is, the key that has been used for encoding cannot be acquired during the period in which the BD-RE copies the content, so it is impossible to decode it.
