Description

200539139 IX. Description of the invention: [Technical field to which the invention belongs] The present invention relates to a write-once optical disc, to a method for recording management information of a write-once optical disc, and to recording and playback of a write-once optical disc. A method of disc and its equipment. [Prior technology] An optical disc is an optical recording medium. The optical disc can be widely used to record large capacity data on the optical disc. Among them, a new areal density optical recording medium (rib-DVD), for example, a kind of Blu-ray disc, which can record and store a wide range of well-defined video materials and quality audio data over a long period of time. Currently, Blu-ray Disc, which is already being developed as the next generation of HD-DVD technology, is a next-generation optical recording solution. Compared with existing DVDs, the DVD has an excellent ability to store data. Righteous Θ month! J. International standards and technical specifications for Blu-ray Disc (BD) are being implemented. In connection with this, various standards for write-once Blu-ray discs (BD-w0) are preparing for the use of rewritable Blu-ray discs (BD-RE). Among the standards for write-once Blu-ray Discs (BD-W0), one method for recording management information is being discussed. This age method includes a method to indicate the recording status of a vehicle. It is a method of writing a human-shaped disc. It indicates that the information of the recording silk of the disc is allowed—Tai Lai or—Nan households can read it at- Write-on Humanoid Disc—A recordable area. This information has various names in existing write-once discs. For example: In the case of the ⑶ series 200539139, this information is called a magnetic weiwei; in the case of the _ series, the bribe is one Rzone (record area) or one segment. ▲ Due to the need to increase the method of effectively recording management information, this aging information corresponds to the recording status of high-density discs. In order to obtain a safe mutual character, this wealth is abundantly available for storage. In addition, there is a need for a method of recording management information on a single light, which requires that this method can be applied to a secondary write-on-density disc for missing words. This method can also be applied to Blu-ray disc. [Summary of the Invention] Therefore, the present invention is directly applicable to a disc and a method and apparatus for recording disc management information, and is a method and apparatus for effectively managing vehicle recording status information, thereby fully Solve one or more problems arising from the limitations and shortcomings of related technologies. An object of the present invention is to provide a write-once optical disc, a method for defining a sector and a sequential recording range (SRR) of an optical disc, and an apparatus therefor. Another object of the present invention is to provide a method for recording information (test) as a disc record residual state f_new and its equipment. The record state information Λ can be applied to this type of writer. Disc. The additional advantages, objectives, and characteristics of Shuming will be partly based on this book. The knife knife will be based on the & outline, and will become those who may learn from the real shot of the invention from the following description. Skilled technicians. The objectives of the present invention 200539139 and other Gamma may be achieved according to its structure. The structure is in the written description, patent translation and book must understand that the above-mentioned general description of the present invention and the following The detailed system of explanation examples is provided in this application. It is provided in this application. [Embodiment] The description will now explain in detail the specific examples of the preferred embodiments of the present invention. They are made in the form of this application. _ Solution method to explain some examples. No matter where you are, you can check all the reference numbers with a reference number, which refers to the same or similar parts. For convenience of description, a write-once Blu-ray disc is described as an example. Most of the terms in this specification are widely used in general terms, but some terms are specifically translated by the applicant, and their meanings will be described in detail in the corresponding sections. If such terms have already been discussed, the present invention should not Understand the simple literal meaning, but understand it according to the meaning of the term. In this specification, the meaning of "SRR" (sequential _Fding stomach 6 1 sequence recording range) is used to record data on an area of an optical disc, using; 丨 member sequence. A recorded § self-recorded unit (sequential rec〇rding_unit: sequential recorded unit). The capacity of an SRR is one cluster or multiple clusters. "SRR information" (sequential recording range information: SRRI) is a name used to identify a recording status of an optical disc. SRRi uses a sequential recording method of the optical disc 200539139 and belongs to one or more SRI ^ "Padding ) "Means 'at the request of the user, or under the control of a recording and playback device (Figure 12)'. Subdata or zero fills an unrecorded area in an SRR. A “Session” consists of one or more consecutive SRRs. The SRR is identified only for compatibility with the recording and playback specifications. Figure 1 illustrates a write-once optical disc designed in accordance with the present invention, such as: "please," a structure and a method for verifying and recording disc management information. As an example, as shown in the figure, the disc has a single recording layer. However, the present invention is not limited to this, it may be finer than-two recording layers or an optical disc having a plurality of recording layers. Referring to Fig. 1, the disc has a lead-in area, a data area, and a copper-out area in all recording layers. The lead-in area and the lead-out area have multiple sides of the disc (or defect) management area where the same defect management information is repeatedly stored. A1-In the data area, silk is provided instead of the inner spare area ISA of the defective area and (or ) An outside spare area OASA. It can be recognized that 'because the ugliness of a rewritable disc can be repeatedly written and deleted, even if the disc has a dirty financial capacity (disemanag_t area.), It depends on the money you can afford. No or need a large DMA. However, it is not suitable for write-once discs, for example, a type of human-writeable disc cannot be recorded repeatedly in the recording-time area, and a human-writeable disc requires and has a large management area. In order to store the management information more effectively, the management information is temporarily stored in a 200539139 5th CD-ROM I management area (temp management area: tdma). When the animal CD is ready or finished, the management information stored in the _ last or last TDMA is transferred to a MA for permanent storage. As shown in Figure 1, the CD includes two TDMA: TDMA0 and TDMA1. TDMA0 is allocated in the lead-in area and has a fixed, non-variable capacity. TDMM is allocated in the outer spare area GSA 'and has a capacity that can be changed according to the size of the control area. The capacity p of TDMA1 can be Yes, for example, p = (n * 256) / 4 towns, where N is a positive integer, which is about a quarter of the total capacity of the outer spare area OASA. In any one TDMA0 and TDMA1, you can Temporary defect list (TDFL) information and temporary disc definition structure (TDDS) information are recorded together (TDFL + TDDS) in a recording unit (for a rib-shame , It is a cluster), or you can record the SRRI and TDDS information together (SRRI + TDDS) in a recording unit as shown in the figure. When using a sequential recording method, record 丨, while manganese uses a In the free recording method, Sbm (space bit map) is recorded. At each update, (TDFL + TDDS) or (SRRI + TDDS) is recorded in TDMA with a capacity of one cluster. In the example shown in Figure 1, one TDFL and one TDDS are recorded in tdma0 with a capacity of one cluster, one SRRI and one TDDS are recorded in the next cluster of TDMA0, and one srri and one TDDS are recorded in TDMA0. In the next cluster, and so on. C 200539139 If a defective area occupies the data area, it will replace it—one owner. The independent scale is treated as a defective table, and it is a single-layered optical county. The size of the muscle defect is the size of the rider, which is 1 to 4 骑. The state of the disc indicates that a special area of the disc needs to be recorded or not. The special money pointed out that it can Effectively applied to the disc-by-face recording method or the incremental recording method = details. In addition, TDDS information is usually recorded in the last magnetic zone of a thief zone in the management area. For discs—the emphasis of generality management and defect management The information record is a part of TDDS information. When the management information is updated, the TDDS information is always recorded last. The present invention relates to a method for generating and recording the recording status information of an optical disc. This method is applied to a new high-level A density optical disc, for example, a type of BD-w0. In the present invention, SRRI is used as the disc recording status information, and the definitions of various SRR types are shown in Figs. 2A to 3E. The detailed structure of the SRRI will be described in conjunction with Figures 5A to 5D. The present invention also defines and distinguishes between different types of SRRs generated on an optical disc and uses these SRRs for recording and playback of the optical disc. In the following, the newly defined type of SRR and a method for generating information to distinguish the type of SRR will be described in detail. Figures 2A to 2D illustrate graphically the different types of open SRRs designed for write-once discs (i.e., a BD-W0) according to the present invention. An open SRR is an SRR in which data can be recorded. If the SRR is recordable, then the SRR has a next writable address "(nWA). Therefore, an open SRR has NWA SRR. 200539139 without NWA 疋 Unrecordable, called a closed SRR. The closed SRR will be described in conjunction with Figures 3A to 3E. In particular, Figure 2A illustrates an invisible srr , It is a type of open SRR. Invisible SRR is always formed on the outermost part of the disc or an initialized empty disc, which means a non-recorded area. In other words, invisible SRR is only A start address is defined. The meaning of the invisible SRR end address is the end of user data. Because the data is not recorded. The "last recorded area" (LRA) has a value of zero and is not visible. The NWA of the SRR is the same as the value of its starting address. Figure 2B illustrates an unfinished SRR, which is another type of open. The unfinished SRR is partially recorded in Figure 2A. One of the invisible SRRs. In other words, the unfinished SRR only defines a start address, and the end address of the unfinished SRR means the end of the user profile. However, because the profile is a partial record In the uncompleted SRR, the LRA of the uncompleted SRR indicates its last address. At this address, normal user information is recorded, and nwa is the next address of the uncompleted SRR LRA. This is the Say, NWA is the first psN of the next available unrecorded cluster in the relevant SRR (phys 丨 ⑺ 丄 sector number ·· physical sector number). For an open SRR 'If the SRR is partially recorded Then, the relationship between lra and · Α is as in Section 2B 'No, this relationship between bumps and dirty related to the filling operation will now be described in detail. The small dotted box in Figure 2B is enlarged. The figure is drawn in the lower part of this figure. 200539139 In other words, the meaning of LRA is the area where user data is actually recorded. As shown in Figure 2β, 'If user data is recorded in some of the 32 sectors, In the magnetic domain, in these The user data is recorded in the zone, the physical zone number (PSN) of the corresponding zone is called the LRA of SRR. However, since the basic recording unit of a Blu-ray disc is a cluster, the NWA representing an additional recordable area will be Immediately following the PSN of a head magnetic zone of this cluster. Therefore, if the recording of data in some magnetic zones of the cluster has been completed (ie the sequential recording is terminated), the remaining unrecorded magnetic zones are in accordance with the invention The design is filled with dummy data. For example, the remaining unrecorded sectors of the cluster are filled with zeros as shown. If user data is recorded in all sectors of the disc even in the last sector of the cluster, it is obvious that the description of the padding operation is unnecessary. Figure 2C illustrates an empty SRR, which is another type of open SRR. The empty SRR it is often not formed on the outermost part of the disc, but contrary to the invisible SRR and unfinished skimming shown in Figures and 2B, data is usually recorded in the middle area of the disc. In other words, ‘it ’s a situation where a host or a user has given an SRR’ but has not yet recorded data on the SRR. Because empty SRR has a start address and an end address. But it has not been recorded yet, so the LRA of the empty SRR has a "zero" value, and the starting address of the empty skim is the same. Figure 2D illustrates a partially recorded SRR, which is another type of open lion. The partially recorded SRR is a partially recorded 撇 R shown in Figure 2C. Therefore, a partially recorded SRR has a start address and an end address. ㈣The data is partly recorded in part of the record ⑽r, part 200539139 Lu Jilu's SRR LRA represents the last address, at this address, normal user data is recorded, and NWA is the next writable bit of LRA site. In the open SRR shown in Fig. 2D, if the SRR is partially recorded, the enlarged view of the small dotted portion in Fig. 2D illustrates the relationship between the LRA and NWA related to the padding operation. Since it is the same as the purpose of 2β, a detailed description of this feature is omitted here. Therefore, seeing Figures 2A to 2D, the open srr according to the present invention can be divided into unrecorded opening force SRR (Figure 2A and $ 2C) and partially recorded open SRR (Figure 2B and Figure 2D). Partially recorded and opened prisons (Figures 2β and 2D) can be divided into open feet that perform padding operations after LRA and open SRRs that do not perform padding operations. According to the design of the present invention, for a write-once optical disc, if the number of open SRRs is too large, it is difficult to manage the total number of open SRRs at any given time and is limited to a predetermined number. For example, in the case of Bp. Of the present invention, the total number of SRRs opened on the disc may be at most 16. For the status of the open lion's life position, you can refer to an "Open T's table" field and an "Open SRR entry number" field under a heading of SRRI. The "Open SRR Table" field and the "Open Shan's suffix L field" will be shown in Figure 5__ on the structure of Jane when a / 3A to 3_ diagrammatic method illustrates the method according to the present invention Designed differently: write-on optical discs, such as: a type of BD, different types of closed prisons. Closed is a job-specific, tear-off technique (that is, 11 200539139 data). If the SRR is not recordable, Then SRR does not have a territory. Because · is full of records, SRR may be generated. Also, even if a recordable area is reserved in Na, because a user or a host has executed a closed order on one side It is also possible to generate a closed SRR. In particular, Figure 3A shows an empty SRR, which is a closed SRR-facet. The empty SRR is an open empty lion (Figure%) ), Because there is no user profile record, it was closed with _ commands. Therefore, Figure 3A illustrates a closed empty SRR, and Figure% illustrates a closed empty SRR. Figure 3B illustrates a partially recorded SRR, which is another type of closed SRR. The SRR of the partial record shown in Figure 3B is the SRR of the open record shown in Figure 2D. It is closed because there is no additional user profile record and a close command is used. Therefore, Figure 3B A closed partial record SRR is illustrated, and Figure 2D illustrates an open partial record SRR. Figure 3C illustrates a completed SRR, which is another type of closed SRR. The completed SRR is An SRR in which the user profile is full of records, or it is filled with dummy data. The completed SRR only exists in the closed SRR. Figure 3D shows a closed partially recorded SRR, which is a closed Another type of SRR. When the SRR of the open partial record shown in Figure 2D is closed, the SRR of the partial record shown in 3D chart becomes one of the recordable areas that are filled with π subdata after its lra. SRR. In At the same time, the SRR is after its LRA or the king of Book 8: § recorded areas or only certain recordable areas (for example: one or 12 200539139 sorry) 'It can be filled with dumb data as filling data. In addition, When filling certain areas, a special character encoding, for example, the ASCn character set can be used as a filling data record to replace the oral Asian data record to indicate that the SRR is off. The special character encoding of the data can be characters such as CLSD, which indicates that a corresponding SRR is closed. Figure 3E shows an empty SRR, which is another type of closed Nana. When the open empty SRR shown in Fig. 2C is closed, the SRR of the worker shown in Fig. 2 becomes a recordable area after filling it with σ subdata, and then closed-one SRR. Here, the entire recording area of the SRR after its impact or orbit or only some recordable areas (for example, one or more clusters) can be filled with oral subdata as filling data. In addition, when filling certain areas, a special character encoding, for example, the ASCII character set can be used as a fill data record instead of a rent data record to indicate that the prison is closed. In this case, the special character encoding used to fill the lean material can be, for example, "asD," a character that indicates that a corresponding SRR is turned off. If the 3D and 3E figures show All closed SRRs are filled with dummy data,-directly to the end address, the closed SRR shown in Figure 3D and Figure 3E is still the same SRR as the completed SRR described in Figure 3C above. In other words, in the present invention, the method for determining the type of the closed SRR is to define two cases of distinguished closed SRRs. These two cases are: -The age order was executed, in the final analysis, the unrecorded remaining areas of SRR were closed without performing the fill operation (Figure 3A and Figure 1), 13 200539139, and the other case was the unrecorded SRR was performed with the fill operation closed. The rest of the area (Figure 3D and Figure 3E). In addition, in the present invention, when an SRR is closed, the SR may be closed without performing a padding operation, or after it is filled with special padding data. Consideration should be given to the compatibility of the 'blue silk disc' with the replay of the same car. Although only based on the SRR or whether the padding operation is performed on the unrecorded area. -A variety of recording and playback equipment (that is, as shown in Fig. 12) can optionally fill the disc and make further progress.-The freedom of designing the recording and playback equipment is further ensured. When the disc is filled, a recording and playback part of the recording and playback device (that is, the component in the figure 12) can automatically record special data, so by borrowing 1 () to receive special data from a controller, you can decide The time problem of the padding operation. The Lai diagram and the 4B_solution method illustrate some examples of = τ = identification information according to the present invention. The padding is a recorded, closed call of a ':: disc, respectively. When you close the open knowledge, you can perform a filling operation on a delivery. However, after editing the SRR opened by the Dagangzhangye, you can respond to the order. Section needs __ ( Also in the case of shirt ten_, where 'filling terminates the sequential recording): Figures are related. ^ ^ What's more special is that, where, the actual user information figure 4A illustrates an open SRR -Information is only recorded in certain areas of a cluster, and the remaining areas of 蔟 14 200539139 are filled with dummy data. Figure 4A shows the padding identification information used to distinguish a magnetic field "Padding-flag ) "In this magnetic In the zone, the actual user data record is filled with σ subdata starting from a magnetic zone, and it is set as the control mark in the corresponding cluster. There are 32 fill marks, and each fill mark corresponds to each A magnetic field of 32 magnetic fields in a cluster of the SRR. As shown in FIG. 4A, in this example, since magnetic field 0 to magnetic field 29 is a region for recording user data, the filling flag of each magnetic field is set. It is a certain value, that is, Ob is used to indicate that no data is filled in the corresponding magnetic field. On the other hand, because magnetic field 30 and magnetic field 31 are areas with filled data, the filling flag of each magnetic field is set to another value For example: "lb" is used to indicate that there is padding data in the corresponding magnetic zone. In this example, LRA represents the position of magnetic zone 29 (the first PSN). Therefore, the optical recording and playback device can decode a cluster containing LRA , Read the padding mark corresponding to each magnetic field, and then accurately identify a magnetic field filled with tons of data in this cluster. Figure 4B illustrates the recordable area in an SRR for a closed SRR. of A special cluster is filled with dummy data. Figure 4B shows the padding identification information “Padding-flag” used to distinguish an SRR. After the padding data is set as the control flag in the corresponding cluster, it is not changed from a closed one. The SRR performs a padding operation to close this SRR. As shown in Figure 4B, in this example, since magnetic zones 0-31 are all 4 areas filled with u subdata, each of the 32 magnetic zones is filled. Standard order, # set to 15 200539139 = "lb", which is used to indicate that the following magnetic field has performed the filling operation. In one word, the f-learning and recording equipment can be used to fill the information (fill the standard), family knife code ' The entry corresponds to each magnetic field filling designation, and then all magnetic fields filled with oral data in this volume are accurately identified. In other words, the 4A _ is used to terminate the filling operation of the record on the disc. The 4β map is related to the filling operation for closing an SRR. Fig. 4A shows that when the sequential recording is terminated, it is used in all other magnetic regions having a radio. Abbé padding: If a padding operation is performed on the corresponding magnetic field, each padding flag corresponds to this, and each of the magnetic pads is set to "Hua," in the case of pure maps, padding- One magnetic area is occupied at the same time. On the other hand, in the case of FIG. 4B, when the knowledge is closed, one or more clusters are filled (one at a time). For the filling of the family, it corresponds to 32 magnetic fields of this cluster. All the filling marks of the district are set Ί 'to indicate that the filling of this 和 is the same as the situation shown in Figure 4β. Figure 4C illustrates graphically the design of a human-designed example according to a concrete example of the present invention. An example of a sector of a type optical disc. A sector is a higher-order record sheet 7t and a lower-order recording unit, for example, a comparison, which contains at least one SRR. Multiple sectors can be recorded on the disc This optical disc is called a multi-segment vehicle. This day ’s pro will combine the concept of fc credits. Baixian, the present invention can allocate multiple ships from the inner magnetic track of the optical disc to the outer magnetic direction of the optical disc. Segment, segment sequence, mosquito _ sequence is assigned to this _ .Even if there are multiple sections' in a given time, there can only be one open section on the disc. This section is the section with the highest section_section number 16 200539139 segment. In other words, at some given time, the segment is formed at the outermost track, it is a recordable segment, called an open segment. When recording is completed or received -One _ command, # 前 打 _ 段 _, becomes a closed section. All in the closed section should be _, become the closed SRR. Here, if the section to be closed contains An invisible Na, the corresponding invisible SRR is not included in the closed, only the remaining Qing is closed. Then, the invisible identities that are not included form a new open section. In In Figure 4C, one Sessi0n # 1 represents a closed section, and one Session # 2 represents an instance of an open section. It consists of one SRR # 1 and one SRR # 2, and sessi〇n # 2 consists of one test # 3, one SRR # 4, one SRR # 5 ... etc. As mentioned above, when the zone is closed, SRR It is also closed. It is still possible to perform a read operation or a money-filling operation before performing a filling operation. Identifying whether to perform a filling operation on a sector is identified by "Padding_flag". When _ unfinished SRR When closed, only _ recorded SRR㊣ domains are closed, and an unrecorded area measured becomes an invisible SRR, forming a new open sector. In-Jiandu㈣-Miscellaneous sectors There is no slow touch of _. Instead, a "segment start bit: Ji Yi ⑽ confrontation order" is provided in SRRI. Table 1 should indicate whether the SRR is the start of the segment. The segment start bit will be later in The structure of the SRRI is described in detail. In addition, although most SRRs can be in the open section (such as Session # 2 shown in Figure 4C), all measurements in this section must be the open SRR. 17 200539139 is sufficient for at least one open test in the open section. In Session # 2 opened in Figure 4C, SRR # 3 and SRR # 5 are open SRR and SRR # 4 is a closed SRR. 5 to 6C illustrate a structure of the SRRI designed according to the present invention and the information contained in the SRRI. In particular, Figure 5 illustrates the overall structure of an SRRI by way of illustration. SRRI belongs to one or more SRRs, and management information provides a record of the disc. SRRI is recorded in the tdma (i.e., TDMA0) of the disc structure shown in Figs. As shown in Figure 5, each SRRI 60 in the TDMA consists of three parts: a header 50, an SRR entry table 30, and an SRR table terminator 40 50 to identify the SRRI. The SRR entry table 30 indicates the status of each corresponding srr record. The SRR table terminator 40 indicates the end or termination of the SRRI. The header 50 is located at the head of the SRRI, and contains a "SRRI structure identifier: SRRI structure identifier, a field of 5 characters_Ust 0f. ^ SRRs. The SRR table field 52 is opened, a "Number of SRR entries: SRR entry number field 53 and a" Number 〇f 〇p coffee d $: open Shan serial number "field 54. Therefore, reading the SRR entry Before the table, you can check the entire contents of the entry. Here, "SRRI structure identifier," field 51 is identified. The table field 52 of the opened SRR informs the position (identification mark ') of the corresponding opened Sb associated with the SRRI, which will be described in more detail later in conjunction with FIG. The '', ',' Number of SRR entries 'field 53 indicates the total number of all Na related to 60. The number of SRR entries opened' field 54 indicates the total number of open identities. Under the heading 50, the SRR entry table 50 is recorded in ·. On the last 18 200539139

After several SRR entries, the end of SRR is marked by the SRR table terminator 40. If SRRI

Should be an end position for SRRI.

Fig. 6A illustrates an example of an SRR entry table 30 recorded in an SRRI designed according to the present invention. As shown in Figures 6 and 8, the SRR entry table 30 is composed of one or more SRR entries 35. Each SRR entry 35 of an SRR (identified by the SRR serial number) on the optical disc transmits information, and its capacity is 8 bytes (64 bits), which indicates the corresponding SRR recording status. Each srr entry 35 includes a state field 31 (state 1) to store the state of the corresponding srr, a start address field 32 to store a start address of the corresponding SRR, and another state field 33 (state 2) Used to store the state of the corresponding SRR. A last record address (LRA) field 34 is used to store the LRA of the corresponding SRR (that is, the end address where the user data is stored in the SRR). Generally, the corresponding SRR start address in the start address field 32 is expressed as a physical sector number (PSN). According to a specific example, the first 4 most significant bits (b63-b60) in the 64-bit SRR entry 35 are allocated to the first state field 31, and the 28 bits below the SRR entry 35 (b59- b32) allocated to the start address field 32, the lower 4 bits (b31-b28) of the SRR entry 35 are allocated to the second state field 33, the last 28 bits (b27-b0) of the SRR entry 35 Assigned to LRA domain 34. 19 200539139 FIG. 6B illustrates an example of the SRR entry 35 in the entry table 30 recorded in srr designed according to the present invention. Status " or to store information identifying whether any padding operations are performed in the corresponding SRR. State 2 field is used to store information identifying whether the corresponding SRR is the start of a sector. As shown in FIG. 6B, since the first 4 bits are allocated to the state i field 31, one bit is used to store a padding identification information “P_flag”, and this “p_flag” is used to identify whether the SRR is padded. Data filling. The other three bits in the first four bits are reserved units, and any changes to the standard will be made in the future. Lu should note that the filling identification information recorded in the SRR entry π is similar. For the filling and information "Filling Lin", the county's figure 4A and the criminal figure are described. However, the objects they identify are different. If a special SRR is filled last, P-marks are recorded in the entry of the SRR, directly Indicates that the corresponding skimmer is a filled SRR. Therefore, the optical recording and playback equipment (Figure 12) can easily check whether the corresponding SRR has performed a filling operation by checking the records of the P-marks. As the management information in the SRR entry. See Figures M and 4B, and after that, as described above, the optical recording and playback device decodes the corresponding thief (SRR) and reads each magnetic field corresponding to the SRR from this frame. Zone Filling Standards Value, so that the optical recording and playback device can determine how much recognition has performed a padding operation after its LRA. In the example shown in the figure, the first bit (31a) of field 31 of state 1 transmits the P-label 'And the remaining 3 bits of field 31 (b) are reserved bits. If p_ is equal to lb, it means that it is a corresponding _ (that is, at least some parts of the SRR have padding data ). If the p_identification is equal to this, it means that 20 200539139 means that the corresponding SRR is an SRR with no padding data. Field 33 in state 2 is allocated 4 bits, and whether the corresponding SRR is the SRR at the beginning of the segment. Information. One bit in the 4-bit field 33 transmits a segment identification information flag, and is used to identify whether the corresponding SRR is the start of a segment. The other three bits in field 33 are reserved units. , Leaving any future changes to the standard. In this example, the first bit (33a) of the 4-bit field 33 stores the S-flag, and the remaining 3 bits (33b) are reserved. Bit. If the S-flag is equal to lb, it means that the corresponding SRR is a zone SRR at the beginning of the segment.

If the S-flag is equal to 0b, it means that the corresponding SRR is not the SRR at the beginning of a segment. One of the reasons for identifying the beginning of a section with a log is to provide compatibility with existing disc structures. For example, DVDs allocate additional areas for distinguishing sections (eg, border-in / border -out). However, allocating additional areas reduces the overall recording capacity of the disc. Therefore, the present invention overcomes this limitation by using the method of SRR entry 35 1 ^: for identifying and reconciling (S-standards). Therefore, the sector structure of the entire disc can use the sector identification information S-marker at the entrance 35 of the SRR to easily identify the beginning of a sector without allocating additional areas to store such sector discrimination information. In order to conveniently describe the present invention, it is described that the P-flag and the s-flag are stored as separate state information in a separate state domain of an SRR entry, but they can also be stored together in a state domain of the SRR entry. The LRA field 34 of the SRR entry 35 is a field for recording an end address (LRA) of a user profile in the corresponding SRR. This field stores a record of user data at 21 200539139 an end address in the corresponding SRR. (Does not contain any filling information). Fig. 6C illustrates the "open SRR table" of SRRi shown in Fig. 5 according to the _ specific embodiment of the present invention in a diagrammatic manner, and the structure of the field 52 is detailed. The information stored in the field 52 is used To determine each open test = or identification information. As shown in Figure 6C, one or more open serial numbers are recorded in the "Open SRR table, 'field 52 as the location information of the open SRR. ^ Two bytes are allocated, recording _ open sequence numbers used to identify a particular SRR. In the present invention, if there are at most 16 open SRRs on the optical disc, the position (identification information) of the corresponding open SRR (and thus the SRR entry opened) is recorded with each open SRR serial number. Therefore, when an optical disc having the optical disc structure of the present invention is loaded, the recording and reproducing apparatus can determine the position of the recordable area (NWA) of the optical disc based on the opened SRR information of the present invention. In other words, the position of the open SRR on the current disc should be obtained from the recorded data. Because there is no information provided at the entrance of srr to identify whether a corresponding SRR is an open SRR or a closed SRR, it is easy to access the practitioner identification information recorded under the title of Satoshi ㈣ Open SRR, so The silk recording and playback equipment can easily read and open the SRR entry related to the SRR identification information.

Therefore, only in the "Open SRR table, the SRR with the SRR sequence number recorded in field 52 is an additional recordable SRR, which acts as an open SRR. After that, if the SRR transitions to a closed SRR, the closed The SRR sequence number of the SRR is cleared from the "Open SRR table" field 52. In this way, the open SRR can be easily distinguished according to the closed SRR 22 200539139. Now, the update of the SRRI that represents the recording status of the optical disc designed according to the present invention will be described. -A method. In particular, you must combine Figures 7A to nB to open and close SRR and sections, and use a sub-data to fill an SRR and record side-a method. Figures 7A to 11B are illustrated The method illustrates a method for sequentially recording SRRIs according to the recording status of the disc # in the write-once optical disc of the present invention. More specifically, FIGS. 7A to 11B illustrate how to sequentially real estate on the disc. # Generate different types of SRR (as shown in Figures 2A to 3E), and how to record SRRI according to the sequence of steps used in a time stream. Here are discussed these methods in conjunction with Figures j to% Times For example, how to achieve this on a BD-W0 with an optical disc structure such as SRR, JJ, and this disc structure. Figure 7A is a description of step 1. Among them, the entire area of the disc is recordable and is an initialized blank. The disc, its designated part is marked with a thick arrow to indicate the position of the NWA. The starting position of the disc is here, there is only one SRR (SRR _ # 1) on the disc. This is the invisible SRR shown in Figure 2A Therefore, a sector is in the initial state of the disc. There is only one open Sessi〇n # ι. The disc is an empty disc, and SRRI is not recorded on the disc. Figure 7B is step 2, where the data (that is, User profile) is recorded on the empty disc shown in Figure 7A, but Session # 丨 has not been closed. Here, there is only one SRR (SRR # 1) on the disc. This is unfinished as shown in Figure 2B SRR. Session # 1 remains as an open section. As shown in Figure 7B, user profile 23 200539139 is recorded in the-section of unfinished SRR # 1, an unrecorded section of SRR # 1 (XIANG) ( (I.e. magnetic domain) is filled with rented data. As mentioned above, SRR The magnetic field filled with dummy data is represented by "Padding_flag = lb". This mark is recorded in an already marked area of the cluster, that is, in the cluster and / or the padding area of SRR # 1. Figure 7C illustrates the process of recording an SRRI in the management area of the disc when the disc is in the state shown in Figure 7β. For the convenience of explanation, the structure of the disc is not shown in Figures 1 and 5. Of all the different parts of the SRRI structure, only certain parts emerge. For example, although (SRRI + TDDS) or (TDR + TDDS) is recorded in a TDMA cluster, such as TDMA0 of a disc as discussed above, only SRRI is drawn in TDMA0 in Figure 7C, as For clarity, TDFL and / or TDDS are omitted. Furthermore, in each field of ㈣ shown in FIG. 5, only the “open SRR table”, the field 52 and the “SRR entry table” field 30 appear.

The recording state of the optical disc shown in FIG. 7C is a case where only one open SRR (SRR # 1) exists in the entire area of the optical disc shown in FIG. 7β. As shown in Figure 7C, when the unfinished SRR # 1 is not closed in the section shown in Figure 7β, SRRI # 1 (60a) subordinate to SRR # 1 is generated and recorded in TDMA 〇 中. In SRRI #i (60a), the pin number (SRR # 1) of the opened SRR # 1 is recorded in its opened SRR table field 52a. In the "SRR entry table field 30a" of SRRI # 1 (60a) There is only one SRR entry 35a subordinate to SRR # 1. The SRR entry 35a (or SRR entry 3, as discussed below) has the SRR entry structure shown in Figures 6A and 6B discussed above 24 200539139. In the entry 35a of the SRR, since some parts of srr # i are filled last, the P-flag is set to "lb" as the status information of the corresponding SRR # 1. Because SRR # 1 is the first deletion of Session # 1 that was opened, s-marks are set to "ib" as the corresponding SRR # 1 status information. Fig. 8A is Step 3, in which a section close command is received and Step 2 of Fig. 7B is executed. Due to the response to the section closing order, the area where the user's information is recorded is divided into a separate closed SRR and a new section generated by the area immediately following the user's data recording area. For example, as shown in FIG. 8A, in the second step, the part of the user data recorded in step 2 is converted into completed SRR # 1 (closed SRR), which turns to form closed gession. At the same time, the unrecorded area is converted into an invisible SRR # 2 (open SRR), which in turn forms an open session # 2. Fig. 8B illustrates a process of recording the recording state (srri) b of the optical disc as a subordinate to the state of the optical disc shown in Fig. 8A. Because this SRRI is the second recorded SRRI, this SRRI is called SRRI # 2 (60b) C3SRRI # 2 (60b) is recorded in TDMA0 followed by SRRI # 1⑽a). For the recording of the disc shown in Figure 8A, the entire area of the disc has only one open SRR (SRR # 2), only one closed SRR (SRR # 1), and the 3 serial number of the open SRR # 2 is recorded in The open SRR table of # 2, domain 52b, and the resources afU related to SRR # 1 and SRR # 2 have been recorded in the "SRR entry table of SRRI # 2, and the domain 30b, respectively, as the SRR entry The 35b and 35c ° SRR entrances (ie, 35b) are shown in Figure 8B (and in other figures). 25 200539139 Shaded, this is a closed SRR entrance. Tian s 丄

u 舄 The newly generated SRR user data has not been recorded, so _Entry (35_ marriage is set to taste. And because Shan # 2 is the beginning of the opened Session # 2, so SRR # 2 entry (35c ) The S-flag is set to "lb". Fig. 9A is step 4, in which, when the disc is in the state shown in Fig. 2, the two opened SRRs are additionally retained in the latest recording material. Therefore, the latest The resulting open SRR is open empty SRR # 2 and SRR # 3, and has a thick arrow ^ No NWA. The result 'Open Session # 2 consists of empty SRR # 2 and SRR # 3 and an invisible SRR Composition of # 4. Figure 9B illustrates the recording state (㈣) of the recording disc by using the g-solution method. The recording state (SRRI) of this disc belongs to the disc-like complaint shown in Figure 9A. Because this SRRI is The third record of the SRRI is called Shun # 3 (60c). The record of SRRI # 3 (60c) is adjacent to SRRI # 2 in TDMA0

(60b). For the state of the recorded disc shown in Figure 9A, the entire area of the disc has three open SRRs (SRR # 2, SRR # 3, and SRR # 4) and one closed S server (SRR # 丨). The SRR sequence number of the SRR (SRR pull, sRRrr, and srr # 4) is recorded in the "Open SRR table, field 52c" of SRRI # 3. Information related to all four SRRs (SRR # 1 ~ SRR # 4) Recorded in the "SRR Entry Table" field 30c of SRRI # 3, and serve as SRR entries 35d-35g, respectively. Therefore, the information Λσ related to the newly generated SRR # 2, SRR # 3, and SRR # 4 has been recorded in SRRI # In 3 (60c), there are no recorded user profiles in SRR # 2, SRR # 3, and SRR # 4. The corresponding SRR entries 35e, 35f, and 35g have P-flags set 26 200539139.

Set it to b. However, 'because SRR # 3 and SRR # 4 are not SRRs that are started from Session # 2, and SRR # 2 is the SRR that is started at the segment, SRR # 2 entry 35e, SRR # 3 entry 35 {and 81 ^ # 4 entry 353 The 8-flag is set to "113,", "Ob", and "〇b," respectively. Figure 10A is step 5, where the user profile is recorded in the empty server 3 and invisible SRR # 4 shown in Figure 9A. Therefore, the first empty SRR # 2 becomes a partially recorded SRR # 2, and the invisible SRR # 4 turns into an uncompleted SRR # 4. The open empty SRR # 3 remains unchanged. SRR # 2 did not perform a padding operation 'recorded the user profile. SRR # 4 records user data but also fills it with padding data. In the magnetic field of SRR # 4 which is filled with the padding data, the padding flag is set to "化." Fig. 10B illustrates a process of recording the recording state (SRR) of the optical disc. This recording state of the optical disc is dependent on The state of the disc shown in Figure 10A. Because this SRRI is the fourth recorded SRRI, this SRRI is called SRRI # 4

(60d). The record for SRRI # 4 (60d) is adjacent to SRRI # 3 (60c). It ’s sad for the disc shown in Figure iOA because the entire area of the disc has three open SRRs (SRR # 2 -SRR # 4) and one closed SRR (SRR # 1). The number of open SRR entries (SRR # 2-SRR # 4) for SRR is recorded in the "Open srr table" field 52d (60d) in SRRI # 4. Information related to all four SRRs (SRR # 1-SRR # 4) is recorded in the "SRR Entry Table" field 30d of SRRI # 4 (60d) as SRR entries 35h-35k.

In this step, the number of SRR entries and the position of the open SRR are the same as in the case shown in Figure 9β, but because the user profile is recorded in a special open SRR 27 200539139, it is recorded in the open SRR entry. The LRA has changed, and the value of the p-tag has also changed. In other words, the information related to record SRR # 2 * SRR # 4 has been updated. Because SRR # 2 records the user profile but does not perform the padding operation, the p-flag of entry 35i of server # 2 remains "0b" unchanged. Because SRR # 4 records the user profile and also performs the padding operation, the P-flag of the 35k entry in SRR # 4 is changed to "lb ,." In addition, because the state of Session # 2 is unchanged, 35h in the SRR entry —3 The S-mark is the same as the SRR entry described in Fig. 9B. Fig. 11A is step 6, in which, when the disc is in the state shown in Fig. 10A, a sector is received and executed Close command. As shown in Figure 11A, SessiON # 2 changes from an open session to a closed Session # 2, and all SRRs of SessiON # 2 are also closed to become closed SRR # 2-SRR # 4. In particular, the additional recordable part of the open SRR is filled with dummy data and closed. The entire additional recordable part of the open SRR can be filled and closed with dummy data. As mentioned above, this is an optional event In addition, when performing a padding operation, special data (for example: CLSD as a character code) can be recorded as padding data as described above. The SRRs that were originally opened, namely SRR # 2, SRR # 3, and SRR # 4, become -One closed SRR # 2, one closed empty SRR # 3 and a completed SRR # 4 form a closed Session # 2. SRR # 2 and SRR # 3 execute a close command, retaining an additional recordable area and turning it into a closed SRR. Here It is optional to fill some parts with dummy data. Therefore, all the magnetic fields in this filling (or) SRR (as shown in Figure 4B) are filled with dummy data. Its p standard path, Padding_flag = lb. However, even in this case, the LRA recorded at the entrance of sxin 28 200539139 means a healthy beam position, and the user profile is actually recorded in xe ,,,, and beam positions. As mentioned above, there is no film studio for the determination of the location of the oral Asian data section. The reserved outermost SRR # 5 is an invisible SRR # 5, which in turn forms a new open Session # 3. Figure 11β is illustrated The method explains a process of recording the recording state (SRRI) of the optical disc. This recording state of the optical disc belongs to the optical disc state shown in Figure UA. Because the S leg is the fifth record in the tube area towel. This is called SRRI # 5 (60e). The record of SRRI # 5 (60e) is adjacent to SRRI # 5 (6Gd) in D. For the recording status of the disc shown in Figure ha, because the entire area of the disc has one open SRR (SRR # 5) and four closed SRR (SRR # 1 SRR # 4) 'The SRR number of the opened SRR (SRR # 5) is recorded in the "

Table J of the opened SRR: or 52e, all previously opened SRR serial numbers (for example: SRR # 2, SRR # 3, and SRR # 4, as shown in Figure 10B) are recorded in Xie # 4, which are currently opened Eliminated in the SRR table 52e. From the "open SRR table, the meaning of domain elimination SRR is that such SRR has been closed. Information related to all five SRRs (SRR # 1-SRR # 5) is recorded in the SRR entry table of SRRI # 5," In the domain 30e, they serve as SRR entries 35b and 35p, respectively. Because SRR # 2 * SRR # 3 is filled with rent data in response to the shutdown order, both SRR # 2 population 35m and SRR # 3 into π 35η are turned _ < < ib ,, This sign indicates that there is at least The -part of the corresponding SRR performs a padding operation. Because the LRA of a population is an end position, the user profile is actually recorded at this end position. The LRA of SRR # 2-Skip # 4 is equal to the value of LRA originally recorded in Satoshi (Xie) 29 200539139. In addition, since the user data has not been recorded on the newly generated invisible SRR # 5, the P-flag at the entry 35p of the SRR # 5 is set to "0b". Because SRR # 5 is a starting SRR of the newly generated Session # 3, the S-flag of the entry 35p of SRR # 5 is set to "lb". As can be seen from Figs. 7A to 11B, SRRI is information indicating the recording status of the current disc. When an optical disc designed according to the present invention is loaded into a recording and playback device, the recording and playback device should check the last SRRI (in the above example, Sie # 5) that was last recorded in the management area. Therefore, it is possible to ascertain the current disc recording status including a recordable area on the disc and / or the position of the SRR. The desired user material can be recorded on a recordable area of an open sector on the disc. Referring to Fig. 12, a diagrammatic illustration of an optical disc recording and reproducing apparatus designed in accordance with the present invention is shown. It is discussed here that such equipment or other suitable equipment or other suitable systems can be used to implement the present optical disc structure and disregard structure and methods. 、, in the control error 丨 1 town you stay; 1 Π „put the unit to record data on the car and ⑷ reproduce the data from the disc, Ping UJ, this record reproduces the data, one for

The disc recording and playback equipment includes a recording and playback unit 10 200539139 computer 16. The interface unit 12 is responsible for communication with external devices, such as a controller. Disc reading unit: Record data directly on the disc or reproduce data on the disc. The data processor 13 receives a reproduction signal from the optical disc reading unit u, and recovers a signal of preference. Modulate the disc with an appropriate signal and transmit the signal. The servo unit 14 controls the signal of the reading unit 2 from the optical disc 'or records this signal to the optical disc. Memory 15 holds temporary data and various kinds of information: including management information discussed here. The microcomputer 16 controls the components of the recording and playback list. Because the recording and playback device shown in Fig. 14 can selectively perform a fiber patch operation ', a designer is free to design the recording and playback device. Recording and playback 1G can automatically store special data when performing a fill operation. The methods of recording and replaying data on a disc can be divided into two categories. The first type is the situation shown in Figures 4 to 11B. They include: a method of completely recording the dragon on an open test, and this kind of square wire fills the rest of the LRA that contains the LRA. ·, Remember to perform the _ operation on the remaining sectors, or when closing one, according to whether the cluster has filled the cluster and recorded the fill identification information. 2. The second category is the one that closes all of the sections when the section is closed. No special buffer is provided between a sector and its adjacent sector. The start position of the segment (ie, the clear SR_segment identification information, such as: ^ mark to identify. Now will be described in detail the method of recording the enemy of the optical disc designed according to an embodiment of the present invention. When the optical disc, For example: a kind of load recording and playback equipment, such as the one shown in Figure 31 200539139 12 when the last SRRI is read out, this increase is recorded as the last disc management information in a TDMA. The question mark and thank you π of the rising rule are recorded in the last SRRI, read out and temporarily stored in the memory 15 of the recording and playback unit 10. The stored SRRI refers to the state of the last disc recording by the month. By Cong The title ’s poor news can identify the open SRR. The data can be recorded in the entire area of the disc through the SRR entrance, or you can check whether the non-recorded state and the open section exist, check the non-recorded state and the position of the open section. , You can identify whether the SRR has performed a padding operation. All such information can be used when the disc is recorded and replayed.

Then, the data (that is, the user data) is recorded in a special open SRR. When the negative material element is recorded neatly in the open SRR, the unrecorded Wei Jun data meaning of lra is included in this cluster (that is, Due to stability and robustness factors) 'padding_flag' is set to "lb". For each padding magnetic field ', padding identification information padding_f i is set to lb. If the magnetic field is not filled, the corresponding padding_flag is set to

Ob. In addition, when the SRR entry in the SRRI is updated, the SRR status information p flag is set to "lb" to indicate that at least some parts of the corresponding SRR have performed the padding operation. In addition, 'for the execution of a by the controller 20. In the case of issuing a section shutdown command to close all SRRs in the section, and for the case where an SRR shutdown command issued by the controller 20 is only to close the corresponding SRR, the microcomputer 32 200539139 16 may also It is called to close a recordable area after performing the filling operation or not (for example: when performing the filling operation, the designer can choose a variety of design solutions: put it in the above situation 'One ODD, ^ ^ ^ 早 凡 丨 0 Automatically fill the closed SR with padding data: ^ system is issued and not executed-a padding command is closed unconditionally ... The self-described function is called the "automatic padding function performed by the recording and playback unit 1Q = the IT system Unit 1G executed an age-filling order and received suction. After that, compared to the case of filling, the automatic filling function has reduced the filling operation time more effectively. In addition, 'If due to the implementation of the above The state of the leg is changed when the padding operation is changed, then the Padding_flag of each padding region is set to lb. Furthermore, the corresponding SRR is set to be set. Various different recording and playback equipment can use this Information. There is a new open segment with a start srr at the corresponding SRR entry. The 3_ flags are set to lb Shaw to indicate the start position of the open segment. Therefore, the present invention provides Defined types and definitions of SRR, and a method of recording SRRI based on the defined SRR types. Therefore, a variety of recording and playback equipment with such desired performance can be used to access various existing discs. Designed in accordance with the present invention The method for recording management information of a write-once disc 'includes defining a new SRR type and a sector type. If an open server has performed a padding operation, or if the SRR is closed due to a padding operation, it is appropriate The padding identification information Padding_flag is set and recorded in the padding area. The other 33 200539139 padding identification information p-flag and section identification information s-flag record Recorded in the entrance. Therefore, for a write-once disc with a new physical structure, management information can be effectively recorded and managed. Obviously, experienced technicians can apply the present invention to various modifications and changes. Therefore, it is intended The present invention covers various modifications and changes made to the present invention by those skilled in the art, and these modifications and changes will appear in the scope of the dependent patent application of the present invention and its equivalent.
