Description

1332195 IX. Description of the Invention: [Technical Field] The present invention relates to a structure formed on a connection area between data blocks on a high-density read-only recording medium to ensure that the reproduction can be compatible with the overwriteable recording medium. rancid. [Prior Art] A disc type recording medium such as a compact disc (C D ) can permanently store a question density digital audio material, so it is a fairly popular medium. In addition, a digital audio-visual disc (referred to as DVD in this article) has been developed as a new disc-type recording medium. A DVD has a much larger storage capacity than a CD, so high-quality audio or audio data can be recorded on a DVD for a longer period of time. Therefore, a DVD is widely used. There are three types of DVDs, read-only DVD-ROM, single-write DVD-R, and rewritable DVD-RAM or DVD-R/W » Recently, a high-density rewritable recording medium called It is a BD-RE (Blu-ray Disc Rewritable, which can overwrite Blu-ray disc), and its storage capacity is larger than that of a general DVD developed by the company. As shown in the 1st circle, a rewritable optical disc bd-RE has a plurality of distinguishing regions consisting of a clipping region 1, a transition region 2, and a burst cutting area (BCA) 3, one. Import area 4, _ data area and a lead area 5. The clamping area 1 is a central area, so that the disc equipment is misplaced for placing a rotating optical disc' and the conversion area is an information area, which is between 5 1332195 and the clamping area 1 and includes the above-mentioned lead-in area 4 and the above Between data areas. After the disc manufacturing process is completed, the bCA 3 system is used to add information to the disc. The import area 4 is the important information required for the optical reproduction, and the export area 5 is where the optical disc is written. The lead-in area 4 is divided into a plurality of areas; a first protection area, a PIC, a first-protection area, a second type of information, a #reserved area, and a first type of information. The first protected area is a protected area that prevents Bca from overwriting the PIC. The PIC area 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 an r1jB (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 real burst, 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 instant 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 the iC chart. ‘As shown in circle 2A, the starting area is determined by . . Channel bit protection E-domain Guard-Ι' and a 1 660-channel bit into a 55-channel 20-bit bit type complex region PrA group ''~, to mark the head of the ,, ^ is ^ The defense area and the first-time data 'Syne_2' are written in the front area ~, in its 6 1332195, Sync_ 1 and Sync _ 2 have a length of 30 channels. Each synchronization data is composed of 24 bits. The synchronization body and the 6-bit synchronization ID are composed. The synchronization IDs of the first and second synchronization data are each '000 1 00, (FS4) and ς 010 0005 (FS6) 〇

As shown in Figure 2, the end zone consists of a 540-channel bit protection block 'Guar d_2' and a 564-channel bit followed by the content 'Ρ〇Α'. 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 '000001' (F S0). 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 to indicate the end of the pre-recorded area called the REB-only record. The user profile is written to the physical cluster and is restored to the original data by the signal processor using the clock synchronized with the synchronization data written in the start zone.

Fig. 1D shows a detailed recording format of the physical cluster of BD_RE, where BD_RE is the location recorded by 31 recording frames (frames #0 to #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 1332195 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 write once and overwriteable discs (DVD-R, -RW, -RAM, +R,

In + RW), a link frame is generated after the previous record area before the new material is recorded discontinuously from the previous record. 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. Despite the differences between writable and CD-ready discs, a conventional disc player, such as a DVD-Player and a DVD-ROM, is required to equip additional entities and/or software for playing both types of discs.

Needless to say, a CD player capable of recording and reproducing a writable disc also needs to be equipped with additional physical and/or software to play CD-ROM and writable discs. Also, a high density called 'BD-ROM' The standard for reading-only recording media is also discussed with BD-RE. Incidentally, if the BD-ROM is the same as the BD-RE, it is advantageous for the disc player to apply the same re-calculation 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. SUMMARY OF THE INVENTION 8 1332195

[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" j, "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 the 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 (consisting of a start region, a physical cluster, an end region, and a protected area) as described with reference to FIGS. 1 and 2; . 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 area of the first embodiment of the present invention, as shown in Fig. 3A, is composed of a guard area 'Guard_l' and a pre-arranged area 4PrA', and the pre-area area 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 1332195 100' and 4〇1〇000', as shown in FIG. 2A, the front area of the BD-ROM constructed according to the present invention Contains two synchronization data, whose IDs are FSO('〇〇〇〇〇i')(Sync_3) and FS6('01 0 000')(Sync_2). In addition, the sync data ‘Sync_3 is placed before the sync data 'sync_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 synchronization data having an id of FS4 ('000 100') (Sync_l). There is a difference in that the synchronization data of the bd-RE with the synchronization ID FS0 ('00O 001') is written in a region after bd_re. In BD-RE, if two RlJBs are generated, a pair of start region and end region are also generated as shown in Fig. 1C. The pair start and end areas (corresponding to a connection area) contain three synchronized data whose recording order is 'Sync_i, 'Sync_2, and Sync_3'. Incidentally, the note in BD_R〇M

The order of recording is ‘Sync_3, ‘Sync_2, and ‘Sync_l, which are opposite 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 Bd_r〇m. In the above embodiment, the start area, the end 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-ROM connection area can be defined in a different manner as shown in Fig. 4A showing the second embodiment of the present invention. As shown in Figure 4, at 14 1332195

In one example of the BD-ROM, the two frames of the same size (1 932 channel bits) constitute a single connection area. In one example of the BD-RE, the start region of the different 1104 bits and the end region of 2760 bits constitute a connection region. The two connection frames are in the same architecture and any frame consists of a 30-bit frame synchronization code, a 9-bit entity address, a 1 1 4 byte data, and a 32-bit parity bit. 114-bit user data can contain 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 feeding operations) ). Fig. 4B shows a third embodiment of the present invention. The connection area of the third implementation is composed of two equal-sized (1932 channel bits) connection frames, and each frame is composed of a 30-channel bit frame synchronization code, a meta-group entity location, and a 146-bit tuple user data. The difference between the constituents of Fig. 4A and the embodiment of Fig. 4B is that there is no parity. 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-R0M to other media) or control (for servo control operations). Fourth embodiment. The connection area of the fourth implementation is composed of two equal size (1 932 channel bits) connection frames, and each frame is composed of a 30 channel bit frame synchronization code byte user data. Compared with Figure 4A, the size of the 4C picture frame is a single channel user's message. In the case of a service control case, the shelf is located in the first place. Physical address and parity. This embodiment also differs from the 48th because there is no physical address. The $4D diagram shows 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 37-four-channel bit connection portion, two 30-channel bit-side synchronization codes, and 40 and 20-way respectively; ;§: a • Consists of two replica modules of the length of the forced position. The connection portion of the 3714 channel bit is composed of three connection frames and 4 & meta-filled data. - The connection area can have any possible architecture that is different from the above. The data is written in the physical cluster in the format of the ECC block, and the above seven frame synchronization codes FS0~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 'FSn, and its synchronization (1) is different from the above seven frame synchronization dailies. The synchronization ID 'FSN of the new frame synchronization code is '1〇〇1〇1 (FS7), '101 010' (FS8), '〇1〇i〇i' (FS9), 'ιοί 001 '(FS 10) As shown in Figure 5. Φ 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 be Satisfy the RMTR (Run-Limited) that is limited by the 17ΡΡ (parity reservation) adjustment

Transition, the implementation of limited conversion) This limit is defined by bd_re 16 1332195 material record standard. The prohibition of RMTR (to ensure that the RF signal is stable) is the minimum execution length of 2T, that is, '01' or '10' cannot be continuously repeated more than six times. Therefore, it tends to use a frame synchronization code with a small conversion frequency, i.e., '1〇〇 101, (FS7) or '101 001' (FS10) achieves a bit conversion that satisfies the limit in the new frame synchronization code. The use of the framework synchronization code will be explained in detail with reference to Figure 6A.

The first condition shown in Fig. 6A is the first embodiment of the present invention. In an embodiment, two 1932 channel bit record frames are recorded in the connection area, and each record frame is composed of a frame synchronization code, a real address, user data, and parity bits. At least one of the record frames contains the newly defined frame synchronization code 'FS η,. For example, the frame synchronization code 'FS0' and its identification module (ID) are written as the first frame synchronization code, and the identification module is '010 101', '101 〇1〇, or '100 101' new The frame synchronization code 'FS η' is written as the second frame synchronization code.

When the synchronous recognition module is '010 101, '101 010, or '100 101, the new frame synchronization code 'FS η' is used, the 9-bit entity address after the frame synchronization code 'FS η' There is an unscrambled starting 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 17-inch adjustment code is for use as a material record on the Bd-RE. For example, if there is a synchronous identification module '1' 101, a new frame synchronization code FS7 is used, and at the same time the physical address bit is '〇1 11 17 1332195 01 11 '' via the 7D picture The adjustment bit made by the 1 7PP adjustment table shown is '010 101 010 101', and finally the adjustment bit of the synchronous identification module constitutes el〇〇101 010 101 010 101, wherein 2T module (one zero The module between one of the two adjacent) continues to appear 7 times.

However, if the physical address includes '00' in its header, the example of the above physical address becomes '00 01 1 1 01 11', and its 17PP adjustment bit becomes '010 1〇〇101 01〇 101'. Therefore, the final bit having the synchronous recognition module constitutes '100 101 010 100 101 010 101'. Among them, a 3T and four 2T 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 record frames contains one of the frame synchronization codes 'FS η' newly defined by the frame synchronization 玛10 ('101 001')'. For example, the frame synchronization code FS0 whose identification module is '〇〇〇001' is written as the first frame synchronization code, and the new frame synchronization code FS10 is written as the second frame synchronization code β when the new frame synchronization generation When the 'FS10' is used, the 1 RMTR limit is defined as the 17PP adjustment of the data recorded on the BD-RE. Therefore, the subsequent physical address does not begin with ‘00’. For example, if the recognition module group is '1 01 00 1 ', the new frame synchronization generation masma fs 1 〇 is used 'while the subsequent real truncated address bit is I 〗 11, 11, and the 7D picture Adjustment bit 18 made by the 17PP adjustment table shown

1332195 is ‘010 101 010 10Γ, and finally contains the sync element to form '101 〇〇1 〇1〇 1〇1 〇1〇 ιοί’, which has '3T and 6 21' modes. The third condition as shown in Fig. 6B is the connection area of the two 1932 channel bits in this embodiment, and each recording frame is composed of a frame co-location, user data and parity bits. Composition. Contains the newly defined frame synchronization code 'FS η'. For example, the first and second frame synchronization codes are one of the synchronization codes, namely FS7 ('010 10Γ), FS9 ('100 101 ') ° when the new frame synchronization code FS7, FS8 or shelf synchronization code FS7, FS8 or FS9 The following 9 has unscrambled start data '00', as shown in Fig. 6A, which satisfies the RMTR limit defined as the data scale code on the BD-RE.

When the new frame synchronization code FS7 ('100 101 is written to the physical address space after the frame with the data is not '01 11 01 1 ,, the RMTR R can be satisfied as shown in the sixth situation as shown in Figure 6B. In this embodiment, two 1932 channel bits are connected to each other, and each recording frame is composed of a frame co-location, user data, and parity bits. Include new frame synchronization code FSIO^IO 001,) . The adjustment position of the identification module shows a 2T and a third embodiment of the invention. The recording frame is recorded in a step code, a physical bit. Both of the two record frames are represented by the new frame FS8 ('101 〇1〇,) and FS9 are used, and the frame byte entity address is displayed. When the above various types of 17PP adjustments used for t are used, the frame synchronization code is followed by the system. A fourth embodiment of the invention. The recording frame is recorded in one step code, one physical position, the two recording frames are all 19 1332195 When the new frame synchronization code 'FS10' is used for two data frames' automatically meets the definition of data records used on the BD-RE RMTR limit for 17PP adjustment code. Therefore, the physical address of each frame after synchronization is not starting with '0 0 '. If the newly defined frame synchronization code 'FS n is used in the above situation, whether an existing area is in a connected area can be easily and accurately judged 'because the new frame synchronization code is different from the physical cluster user"

For example, when the combination of the frame synchronization codes is used to discriminate the existing area, since the combination of a frame synchronization code is composed of 'FS η' and FS4 written in a connection area, each is written to the previous entity. FS4 and FS2 of the 29th and 31st record frames (record frames #28 to #30) in the cluster become FSn-FS4 or FSn-FS2, which are also significantly different from the frame synchronization code written in a solid cluster. The combination of production. Whether an existing area is in a connected area is precisely determined based on a combination of frame synchronization codes. The seven scenarios described above are summarized below.

Any other four frame synchronization codes can be used if the appropriate restrictions are applied to the data to be written after a frame synchronization code. For example, if an address of an entity is written after the frame synchronization code, if the address of the entity always has a header of the element '00', the frame synchronization codes FS8 and FS9 can be used unimpeded. In the special case where a physical address is not written, if a byte, for example, '08h, (〇〇〇〇1〇〇〇) is not exactly after the frame synchronization code, it is scrambled by ' 17PP from '08h' adjusted bit chain '〇〇〇1〇〇20 1332195 100 1 00' is placed after the frame synchronization code, can use any four new frame synchronization code FS7-FS10, without considering RMTR constraint. The frame 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-FS 6 is in a connection frame. Needless to say, this new framework synchronization code can only be used in Cases 3 and 4 of Figure 6B, as shown in the two connection framework. If at least one selected from the new frame synchronization code 'FS η' is used to connect the frame, when the recorded data is reproduced from a BD-ROM, the optical disk player (as shown in Fig. 9 is read and written by an optical device) The head η, a vdP system 12 and a D/Α converter 13) can quickly know whether the currently read frame is within the connection area or a data section (solid cluster). In a BD-RE, '3 1 record frames respectively include seven different frame synchronization codes. However, the seven frame synchronization codes are not sufficient to clearly define 31 record frames, so the frame synchronization in the previous record frame Used to identify an existing record frame and a frame synchronization code in an existing framework. The s' can be identified by the continuous synchronization code of its own frame synchronization code and the frame synchronization code in the previous record frame N-1, N-2, and/or n-3. That is, although one or two previous synchronization gemas N-1 and/or N-2 are not detected, the last detected ν·3 can be used together with its synchronization code and the recording frame. Do identification. For example, assuming that the existing recording frame is the eighth, that is, the record frame #7, then the frame synchronization code of 匕 is FS1 shown in the 1D chart. 21 1332195 However, the frame synchronization code FS1 is also written in frames #1, #23, and 24, so the existing frame is identified by the previously detected frame synchronization code. At present, the framework of the detection synchronization dynasty FS1 and the previously detected framework synchronization code FS4'FS1' and/or FS3 (in frames #6, #5 and #4 respectively) can identify the existing frame as the #7th °

As mentioned above, since the data frame is identified by the arrangement of the frame synchronization code, it should be noted that the frame synchronization code sequence (from the previous data frame to the record frame in the connection area defined by the new frame synchronization code) is explained in detail. Figures 7A through 7C. Figures 7A through 7C show the sequence of code synchronization codes in accordance with the present invention. Fig. 7A is the first case shown in Figs. 6A and 6B. Figures 7B and 7C are the synchronous gamma pairs of FS7-FS7 and FS7-FS8 in the third case shown in Figure 6B, respectively. If the FSO and fS7 framework synchronization code is used as shown in Figure 7A, the frame synchronization code before the frame with the frame synchronization code FS〇1. N2 and N-3, in turn, fs7, FS0 and As shown in case (1). Frame #〇 corresponds to the first address unit of a RUB. As shown by ease (2), the three frames in the frame of the second column are in the order of frame synchronization mega FS2, FS^ FS4e frame # 〇 corresponds to a RUB intermediate address unit. As shown by ease (3), the three frames in front of frame #1 are synchronized to FS〇, FS7/FS^ FS4. Therefore, frame #1 corresponds. In addition, the frame synchronization code 22 1332195 of the three frames between the frame unit #2 and the intermediate unit of the first address unit or a RUB is sequentially FS1, FSO and FS7 / FS2, such as case (4, red _ ^ , _ does not. So frame #2 corresponds to the first or intermediate unit β of a rub, as described in the 'Α, symbolic case of the 7th diagram, the second frame and the intermediate address unit of a RUB Correspondingly, according to the innovative design of 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 adopt the pair of FS0 and FS7 will not be an appropriate solution.

In the following example, FS7 shown in Fig. 7B is taken as an example of interpretation. As shown in case (1) of Figure 7B, the framework synchronization code before frame #〇 is FS7/FS2 ’ FS7/FS4. And FS2/FS4. The frame #〇 is the first address unit or intermediate unit of rub. As shown in case (2), the framework synchronization code before the framework is FSO, 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 fsI, FS0. And FS2. Frame #2 is also the first or intermediate unit of RUB. However, as shown in FIG. 7B 'B, as shown in the example of the invention, according to the innovative design of the present invention, the first connecting frame (frame #31) and the second connecting frame (#32) are in the frame frame N and the frame N-3. Having the same framework synchronization code sequence, and its ambiguous connection area can cause problems. However, if the two connection frames use two FS7s, and there is a newly defined frame synchronization code FS7 » when detecting a connection area, the problem caused by this situation of FS7-FS7 is no more than the FS0-FS7 of the 7A圊The situation is serious. Figure 7C shows the implementation of FS7 and FS8. As shown in case(l), the framework synchronization code before frame #0 is FS8/FS2, 23 1332195 FS7 / FS4 and FS2 / FS4. Frame #〇 is the first or intermediate address unit of the RUB. As shown in case (2), the framework synchronization generation before frame #1

The code order is FSO, FS8/FS2 and FS7/FS4. Frame #1 is the first or intermediate unit of the RUB. In addition, as shown in case (3), the framework synchronization code before Frame #2 is FS1, FSO and FS7 / FS2. Frame #2 is also the first and middle unit of the RUB.

As shown in Figure 7C, before any framework, FS7 and FS8 are used to represent different previous frame synchronization code sequences, ie, the previous frame synchronization code sequence before any frame is unique, so the detection is opposite to the 7A. When it is connected to one of the 7B charts, it does not cause a problem. Thus, the use of FS7 and FS8 is a preferred embodiment of the connection area constructed in accordance with the present invention. Further, the frame synchronization codes FS7 and fs8 satisfy the RMTR constraint as described above. Figure 8 is a flow chart of a method for reproducing a recording medium in accordance with an embodiment of the present invention. The bd-rom is loaded (S81), and the management information for re-control in the bd.rom is first read into a memory (S82). Because in general, the management information has been written into the lead-in area, which is started by a read/write head in the initial: standby phase under the control of the control unit. System (S83). During the reproduction period, it is checked whether or not the detection frame-synchronization daisy (S84) 4 is detected to determine whether or not the synchronization code written in the synchronization area of the detection is (S85). If the comparison - the recording of the synchronization code F SO ~ FS6 stored in the recording/reproducing component of the recording and reproducing component, and the detected synchronization code, can be discriminated"

If it judges that the detected synchronization code is a synchronization code (FS0 to FS6) written in the main material area (S86), the relay is reproduced. However, if it judges that the detected synchronization code does not belong to the synchronization code (FS0-FS6), it means that it is the newly defined synchronization code FS7 or FS8, an existing location is associated with a connection area (S87), and then checks again whether In the first connection frame or in the second connection frame (S88). 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 head n, a VDP system 12, and a D/A converter 13, as shown in Fig. 9, when a BD-ROM is placed therein, A user profile and a physical address in the first and second connection frames (record frames #k+1, #卜2) of the BD-ROM are accurately detected. In particular, if the user profile contains useful information about anti-infringement copyright or servo control, use CD-ROM to perform appropriate operations on useful information. As mentioned above, 'whether-the existing position (the optical head is located on it) is located within the -connection area or the main data area, and can be compared and easily compared with the newly defined frame synchronization code. I know. (2) Physical address As in the record frame area shown in Fig. 4A, the write frame structure 5 in the record frame 5 enters a physical address in the 10A, and there are three types of 25 1332195 cases. In the first case, the AUN closest to the physical cluster #k+l after the frame is written in both connection frames. The second case is the closest physical cluster AUN that was written before the framework. 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 #k+l after the second connection frame is written to the The second connection frame.

The physical address (consisting of the address of 4 bytes, the reserved 1 byte and the parity of 4 bytes, as shown in Figure 11A) is encoded by RS (9, 5, 5) , with error recovery capability 'for 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's data contains useful information about anti-infringement copyright 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 #k+l after writing the frame in the three connection frames. The second case is written to the closest physical cluster #ki AUN 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 11A) is RS(9,5,5) 26 1332195 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. Fig. 10C shows another embodiment of the present invention, which writes an address in the recording frame. Any of these connection frames (record frames #k+l, #k + 2) contain a 9-byte entity address' and the entity address contains a 4-bit real address. The 4-bit real address may have 16 AUNs #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 in front of the first connection frame is a 27-bit address, and a 4-bit sequence code (0000~1111) for indicating its order in the physical address. ) and a 1-bit fixed value of '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 (0000~ used to indicate its order in the physical address) 1111) and a 1-bit fixed value of '0', as shown in Figure 10C. All of the physical clusters written after it 27 27

The 1332195 bit address 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 1, 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-bit 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 'Γ to indicate that a physical address is written to a connected area instead of The last five of the 4-bit real address written by an entity I 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 be '11110'. In addition, an address written into a physical cluster may be written in the second connection area, and the physical cluster is one of the physical clusters before and after the connection area, as described in the previous section of FIG. 10C ( 3) Scrambling Figure 11A shows the structure of the connection frame of the structure shown in Figure 4A. The flow includes the first six [110, the first 1' is not connected to the AUN i, the frame, and the t set. The bit address '- and or the square 28 1332195 circle. The flow of the framework of the connection framework includes scrambling 10 and adder 20. The scrambler 10 scrambles the user data of the 1 1 4 tuple with the physical address of the 9-byte tuple so that its DSV (digital sum value) approaches zero and is used after scrambling. Add a 9-bit entity address zero before the data.

The adder 20 adds 32 bytes of parity from the scrambler 10 and the 20-channel bit frame synchronization code before the user data of the added address. It is located after the user data of the added address. Thus, a complete recording frame is constructed which contains 114 bytes of user data, and the 114-byte user data is scrambled with a 9-bit physical address. In terms of scrambling of user data, information other than a physical address of a 9-byte can be used. Figure 11B is a block diagram of another connection frame for the framework construction process shown in Figure 4D. The architecture of the connection framework includes scrambling 10' and adder 20·. The scrambler 1 (scrambles a user data of 62 bytes (such as anti-infringement information) with a 9-bit physical address to bring its DSV (digital sum value) closer The physical address of the 9-bit tuple is added to zero and before the scrambled user data. The adder 20 adds 32-bit tuple parity from the scrambler 10' after the user data of the added address. Thus, a record frame constituting a complete 103-bit tuple includes user data of 62-bit tuple scrambled with a physical address of 9-byte. The scrambling aspect of the user data can be used except one 9-bit entity information outside the physical address. Contrary to construction including frame synchronization code, 9-bit entity bit 29

1332195 address, 1 14-bit tuple user data, and 32-bit tuple connection framework, as shown in Figure 4A, can be constructed with a frame synchronization code, 9-bit entity address, 1 The parity of the byte and the 4-byte, and the 146 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 scramble key. That is, in the scrambling process, a portion of the 4-bit entity bit (AddO~Add31) is used as an initial load value of a 16-bit recorder 101, as shown in the recorder 101 in FIG. 12B. After loading the initial load value in parallel, each bit is scrambled. Because in the embodiment of Fig. 9, the length group ' of the user data' is loaded in parallel with each of the 146 conversions in the conversion register 1〇1. After some of the addresses to be loaded are loaded due to changes in the connection area, 146 scrambling bytes (s〇~S145) are created to repudiate or close "1" 2 to 146 consecutive bits of user data. "Exclusive or". Thus, the continuous group scrambled as before is written into the connection frame. In addition to the physical address, some replicas of one of the frame sync code modules ‘1〇’ can be used as a high-frequency key to the user. In addition, one of the real addresses written in the connection frame can be used, which is included in the -trend cluster after an existing spin box. In particular, the closest parity connection frame among the 16 addresses, including the reserved byte, is a 32-bit conversion of the real address of the 146-bit tuple. In the conversion, the conversion output is a change of 1 4 6-bit entity address. In parallel, it is disturbed by a mutual (D0-D145) 1 4 6-bit or bit data, 16 addresses. An address of the frame before or before the existing connection frame 30 1332195 is used. β The physical address of one of the connection frames to be written can be scrambled together with the user data written therein.

In another embodiment of the invention, it is not possible to write a physical address in the connection frame as shown in Figure 4C. In this case, a physical address before or after the connection frame is used as a scramble key, that is, an initial load value stored in the conversion register. Since the user data length is 155 bytes in this embodiment, every 155 conversions, the same or different physical addresses are used as an initial value to load the conversion register. As shown in Fig. 13, one part of the 4-bit address (Add#0~#3 1 ) is loaded into the 16-bit conversion register 1〇1 of the scrambler in parallel, and the scrambler is also Applicable to the recording of BD-RE, and then, in the bit conversion process, 155 8-bit scrambling bits are sequentially output and (s〇~sl54). The consecutive 155 scrambling bytes (S0~S154) are "mutually exclusive" by a "mutually exclusive or gate" 102. with a continuous number of 55 user bytes (do~D1 54). Therefore, 155 scrambled user data (D, 〇 ~ d, 154) are generated and they are written into the recording frame of a connected area. In addition to a physical address, it is possible to use a portion of the frame synchronization mega module or a copy of the bit as a scrambling key to scramble the user data. (4) Filling data When anti-infringement copyright or useful information of servo control is not written into the user data space 'Although a BD-ROΜ connection area forms two recording frames to ensure compatibility with BD-RE reproduction It is possible to fill the user data space with an arbitrary value 31 1332195 (for example, 'OOh'), as shown in Figure 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 fill data, certain values (eg, '〇〇h', 'Olh', '10h', 4llh', 'FFh', 'A Ah', etc.) are sequentially Written and used

In the data space, as shown in Figure 14B, to reduce the possibility of crosstalk. In the embodiment of the padding data record, padding data of different values are recorded in the recording frame of each connection frame deployed in a BD-ROM, 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 compatibility with BD-RE reproduction. 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., '0', '01', '11', which alternate as shown in Figure 14C. In the embodiment of the padding data recording of Fig. 14C, 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 tracks is small, and therefore, the possibility of occurrence of crosstalk is lowered as compared with the embodiment of Fig. 14A. The process of the BD-ROM of this embodiment is simpler than the one of Fig. 14B. 32 1332195 Furthermore, if a value (e.g., 'OOh') fills the entire user data space after scrambling with one of the physical addresses of each of the connected areas, the crosstalk can be greatly eliminated. After the scrambling, if '〇〇h' fills the user data space, if an unscrambled '08h' is placed at the top of each user data space, then any of the above new ones can be utilized. The 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 by channel coding to ensure its reliability, RS (62, 30, 33) and (24 8, 2) 1 6,3 3) The coding system is used as a channel coding method. Those coding systems are also set to encode user data for a BD-RO Μ entity cluster. Figure 15 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, 30, 3 3) system first encodes the useful data for the 30-bit tuple, which creates a 32-bit parity bit. For operation, a memory sequentially stores the input data to organize a 30x309 data block. When a 30x309 data block is organized, each column (151) is scanned sequentially. The RS (62, 30, 33) encoding system produces a 32-bit parity bit, and all operations scan the column and attach it there. Finally, a 62-tuple data sequence is structured. Each 62-bit tuple containing parity bits can be scrambled. If scrambling is performed, one of the physical addresses can be used as a scrambling record as described in 33 1332195. 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, a 9-bit entity address 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, 216, 33) 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 bytes to generate a continuous 103-bit data unit. After the three cells were fabricated, the three cells were followed by 4 padding bins, after which a total of 2467 bins were subjected to a 17PP adjustment. After the 17PP 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 30 channel bits, and the 40-channel bit repeats the bit module, repeating The third 30-channel bit frame synchronization code of the bit module and another 20-channel bit are sequentially appended to the adjusted bit. The 3864 channel bits thus generated are written to 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-tuples in each connection area 34 U32195 must inevitably constitute a single data sheet. Therefore, as shown in Fig. 15C, in a 3〇χ3〇9 data block, a straight row of 309 bytes is written in only one column and the other 29 columns are all filled in the padding data. In each straight line, in. The padding data of the byte is added to the useful data of the 1-byte. Finally, an RS (62, 30, 33) encoding system is used to fill each of the added 3 〇 bytes to add a 32-bit parity to the parity. To restore 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 bar domain as shown in FIG. 4B, the user data space of the connection frame can be filled with the 114-byte useful data and the 32-bit parity bit shown in FIG. 4A. . Figure 4a illustrates the use of a different method described in Figure 4B or Figure 4C for channel coding to ensure data reliability. For details of this method, see page 16 _ ° Try to collect useful information for up to 2048 bytes (S 1). A 4-byte EDC (Error Detection Ma) is attached to the / useful data block (S2) composed of the 2048 collected bytes. A data unit (S3) containing 2052 bit components of the EDC ▲ eighteen 114 bytes will be included. The first data unit is scrambled (S4)' and the 9-bit real address is added to its head (s5). The padding data of 93 bytes is added to the data unit of the 123-bit group containing the physical address and is encoded by the RS (248, 216, 33) system, thereby adding the parity of the 32-bit tuple to the data. Unit β removes the 93 added bytes to generate 155-byte frame data 35 1332195 (S 6), which is then adjusted by 17PP. Finally, the framework data is added to the above-mentioned 30-channel bit frame synchronization code to complete the connection frame of 1932 channel bits (S7) » One of the above series of processes (S4-S7) is applied to the 114 bytes that are subsequently cut. The data unit is used 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 114-byte data unit, 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 real address of 4 bytes, a reserved 1 byte, and a 4-bit parity bit. 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 '00000/11110' or '00001/11111' can be used as the address identifier. If the former (or the latter) is used, '〇〇〇〇〇' (or '00001') is inserted into one physical address in a connection frame, and '11110' (or 36 1332195 iiiii') is inserted in another Connect the frame. The new frame synchronization code 'FS η' described in the above section (different from the synchronization code "FSO~FS6" used for the data frame for writing the actual cluster) can be used for the connection framework. If a new root synchronization code different from the synchronization code of the data frame is used, the data written in the physical 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 recorded in a BD-ROM with such a translated password is copied to the overwrite disc 'for example, BD-RE, the new frame synchronization code 'FS η' in the connection frame is not copied to a bd-RE. Above, and not during the Bd-RE recording. That is, the key that has been used for encoding cannot be obtained during the period in which the RE is copied, so it is impossible to decode it. Therefore, the above configuration of a media connection area of a high-density read-only recording of the present invention can be made free of illegal copying of a content on a BD_R〇M to ensure a rewritable recording medium with, for example, Jm ~r ^ ^ BD-RE The rework compatibility is when it is reproduced by a optical broadcast player or a first disc player. In addition, in the case of a disc player or a virtual block, and if necessary, the structure of the connection area of the present invention enables it to be quickly made by recording a record-only medium with a rewritable medium. The division is also W.3⁄4 volume' to carry out the appropriate operation. In addition, the useful page can be stored in a connection area on the right side through the above recording method. Although it has been revealed that there is a departure from the spirit of the invention. Therefore, it is noted that certain specific embodiments of the invention of the invention are not to be construed as being limited by the scope of the invention.
