Description

1314727 IX. Description of the Invention: The present invention relates to a write-once optical disc, a method for recording management information of a write-once optical disc, and a method for recording and playing a write-once optical disc Method and equipment. [Prior Art] Since the optical disc is an optical recording medium, it can be widely used to record large-capacity data on the optical disc. Among them, a new high-density optical recording medium (HD_DVD) (such as a Blu-ray disc) is currently under development, which can record and store a wide range of video materials and high-quality audio materials for a long period of time. Blu-ray Disc (BD) is the next generation of HD-DVD technology and the next generation of optical recording solutions. It has excellent data storage capabilities compared to existing DVDs. Currently, technical specifications for international standards for HD-DVD have been established. Related to this, after the rewritable Blu-ray disc (BD-RE) standard, a write-once Blu-ray disc (BD-WO) is being prepared. Various standards. In the standard of write-once Blu-ray Disc (BD-WO), a method for recording management information has been discussed. This method involves a recording method of information (used to indicate a recording state of a disc) and is one of the characteristics of a write-once optical disc. The information used to indicate the status of the disc recording allows a host or a 5,14727 to find a recordable area. There are various names for this kind of information. For example: for a track information (track ' information called - Rz〇ne households can easily be on a write-once disc in an existing write-once disc, this is the CD series, this information is called Information); in the case of a DVD series (recording area) or a fragment (fragment). Therefore, a need for an effective method of recording management information (corresponding to the recording state of a high-density optical disc) has been increasing. In order to achieve a safe mutual compatibility, this method must be provided with information on the 'real world'. In addition, there is a need to record the answer on a CD. A method of managing education has been recorded. This method can be applied to the write-once type of high-quality farmer's seven-density compact disc for defect management, and can also be applied to Blu-ray discs. SUMMARY OF THE INVENTION Accordingly, the present invention is directed to a disc and a method and apparatus for recording information management information of a disc, and is a method and apparatus for efficiently managing information on recording status of the optical disc, thereby solving the problem related to the disc. One or more problems arising from technical limitations and shortcomings. SUMMARY OF THE INVENTION An object of the present invention is to provide a write-once optical disc, a method and apparatus for defining a type and a sequential recording range (SRr) of a section of a disc. Another object of the present invention is to provide a method for recording SRR information (srri) as a disc recording status information, and the information of the first recording status can be applied to the write-once type. CD. Additional advantages, objects, and features of the invention will be set forth in part in the description in the description. The object and other advantages of the present invention may be realized and obtained in accordance with the structure thereof, which is particularly pointed out in the written description, the scope of the claims, and the drawings. It is to be understood that the foregoing general description of the invention and the claims [Embodiment] The description will explain in detail preferred embodiments of the invention, which are some examples of illustrations of the invention in the form of drawings. Wherever possible, the same reference numerals will be used throughout the drawings to refer to the same. For convenience of description, a write-once Blu-ray disc (BD-WO) will be described as an example. Most of the terms in this specification use generic terms extensively, but some terms are specifically chosen by the applicant and their meaning will be described in detail in the corresponding sections. If the meaning of such terms has been discussed, the present invention should not be understood in a simple literal sense, but rather in terms of the meaning of the specifically recited terms. In the present specification, the meaning of "SRR" (sequential recording range: 13,14727 sequential recording range) is a field for recording data on a disc, and is used for the order of the recorded ones. Sequential recording-unit: sequential recording unit). - The capacity of the SRR is _ cluster. SRR information (SRRI) is the name used to identify a record status of a disc. The SRRI is applied to a sequential recording mode of a disc and is multi-SRR. "Padding" means that an unrecorded "segment" is filled in an SRR with dummy data or a value of zero according to a user or under the control of a recording and playback device (Fig. 12). ), is composed of one or more consecutive SRRs [other SRR (only for compatibility with the specification of playback). Figure 1 illustrates one of the write-once optical discs BD-WO designed according to the present invention) The structure and a method for recording a disc management information. For example, the disc shown in the figure has a single record. The present invention is not limited thereto, and it can be applied to a disc having two recording layers having multiple recording layers. Referring to Fig. 1, in all the recording layers of the optical disc, there is a lead field, a data area, and a lead-out area 1 into the area and the lead-out area. A plurality of optical disc (or defect) management areas (DMA1 to DMA4) repeatedly store the same defect. Management information. In the data area, - the internal spare area ISA0 and/or an external spare area 〇SA〇, use the defective area. It can be recognized that even if the disc has a limited capacity area - or more range information about one The area of interest and the identification (for example, the square layer. However, there is a DMA (disc 13, 14727 management area) that is provided in the layer or in the area because the DMA can be repeatedly written and Delete, so a re-writable disc does not have or does not require a large DMA. However, it does not apply to write-once discs such as a BD-WO. Because write-once discs cannot be recorded. Once in a single area, it is recorded again, so a write-once disc requires and has a large management area. In order to store management information more efficiently, 'in a write-once disc' management information is temporarily stored in a temporary disc management area. (temporary disc management area, TDMA). When the disc is ready to be completed or closed, the management information stored in a last or latest TDMA is transferred to a more permanent storage DMA. As shown in Figure 1, the disc Includes two TDMAs: TDMA0 and TDMA1. The TDMA0 is allocated in the lead-in area and has a fixed, non-variable capacity. The TDMA1 is allocated in the outer spare area (〇uter spar-e ar Ea) OSA 'has a capacity that can vary depending on the size of the spare area. For example, the capacity P of TDMA1 can be p = (n* 256) / 4 clusters (N is a positive integer 'it is about the outer spare area〇 SA〇 is a quarter of the total capacity. In any of TDMA0 and TDMA1, the temporary defect list (TDFL) information can be combined with the temporary disc definition structure (TDDS) information ( TDFL + TDDS) is recorded in a recording unit (which is a cluster for a BD-WO), or SRRI and TDDS information (SRRI + TDDS) can be recorded in a recording unit as shown. The SRRI is recorded when a sequential recording mode is used, and when a random recording mode is used, SBM (space bit map) is used. At each update, (TDFL + TDDS) or (SRRI + TDDS) is recorded in a TDMA with a capacity of one cluster. In the example shown in Fig. 1, a TDFL and a TDDS are recorded in a TDMAO of a cluster, an SRRI and a tdDS are recorded in the next cluster of TDMAO, and an SRRI and a TDDS are recorded in the TDMAO. A cluster, and so on. If a defective area occurs in the data area, a program is executed to replace it with the spare area. TDFL treats this program as management information for the defect table. For a single-layer disc, the TDFL sets the recorded capacity to 1 to 4 clusters according to the size of the defect table. The SRRI is a piece of information that is used to notify the disc that a special area does not need to be recorded. When the disc is a continuous type, ni. j C r> rfc τ

SRRI can be widely used. In particular, SRRI can be effectively applied to the following situations: The disc is in a sequential or incremental recording mode & spicy. In addition, the TDDS information is usually recorded in the last magnetic region of the 32 magnetic regions of the management area. The general management information and the deficiencies of the CD-ROM are recorded as part of the TDDS information. When in the TDMA-Hongda Dingji new management information, usually the TDDS information is always recorded last. The invention relates to a method for generating and recording recording state information of an optical disc, which is applied to a new high-density optical disc which is as difficult as BD-WO. In the present invention, the SRRI system is used as the information on the recording state of the optical disc, and the definitions of the various SRR types are as shown in Figs. 2A to 3E. The detailed structure of the SRRI will be described with reference to Figs. 5A to 6C. The present invention also defines and distinguishes between different types of SRRs generated on a disc, and uses these SRRs for recording and playback of optical discs. A newly defined S RR type and information generated to identify the S RR type are described in detail below. Figures 2A through 2D illustrate different types of open SRRs for write-once optical discs (e.g., a BD-WO) designed in accordance with the present invention. An open SRR is an SRR that can record data. If the SRR is recordable, the SRR will have a "next writable address" (NWA). Therefore, an open SRR is an SRR with NWA. The SRR without NWA is an unrecordable SRR, which is called a closed SRR. The SRR for shutdown will be described with reference to Figures 3A through 3E. More specifically, Figure 2A illustrates an invisible SRR, which is a type of open SRR. The invisible SRR is usually always formed in the outermost part of the disc or in an initialized empty disc, which means a non-recording area. In other words, the invisible SRR only defines a starting address, and the invisible SRR's ending address represents the end of the user profile. Since the data is not recorded, the "last recorded area" (LRA) has a value of zero, and the NWA of the invisible SRR is equal to the value of its starting address. Figure 2B illustrates an unfinished SRR, which is another type of open SRR. The unfinished SRR is an SRR that is partially recorded in the invisible SRR shown in Figure 2A. In other words, the unfinished SRR only defines the end of 11 13.14727 a starting address. However, the next available number of the LRA that is not recorded in the address is not the same as the dotted line in the NWA 补 操作 换 换 换 换 换 换 换 换 ; ; ; ; ; ; ; ; ; ; ; ; The basic recording area will be I. The recording according to the present invention has been completed using the virtual data recording magnetic area for recording the user.

The design, while the unfinished SRR's east address represents the user profile and 'because the data is partially recorded in the unfinished SRR, the LRR is the last address (in this normal user profile), NWA is the address of the unfinished SRR. That is to say, the NWA is the first PSN (physical sector) in the next recorded cluster in the SRR. The SRR of the release, if the SRR is partially recorded, the relationship of the LRA 3 is as shown in Fig. 2B, and this relationship between the LRA and the NWA will now be described in detail. An enlarged view of the μ map is shown in the lower part of this figure. Said that the meaning of LRA is the area where the user data is actually recorded. It is indicated that if the user data is recorded in some magnetic regions composed of 32 magnetic regions, the latest magnetic domain number (PSN) recorded in the user data is LRA. However, because the Blu-ray recording unit is a cluster, NWA (represents an additional recordable

Then, the pSN of a head magnetic region of the cluster is filled if it is recorded in some of the magnetic regions of the cluster (i.e., the sequential recording is terminated), and the remaining unrecorded magnetic regions are filled. For example, as shown, the rest of the cluster is not filled to fill. * Even if the data is in the last _ magnetic region of the plexus. It is obvious that the filling operation is not 12 1314727. Figure 2C illustrates an empty SRR, which is another type of open SRR. Unlike the invisible SRR and the unfinished SRR shown in Figs. 2A and 2B, the empty SRR is usually not formed at the outermost portion of the disc, but is usually formed in the middle portion of the disc to record data. In other words, it is in the case where a host or a user forms an SRR, but no data has been recorded on the SRR. Since the empty SRR has a start address and an end address but has not yet been recorded, the LRA of the null SRR has a "zero" value, and the start address of the NWA and the null SRR is the same. Figure 2D illustrates the SRR of a portion of the record, which is another type of open SRR. The partially recorded SRR is an SRR that is partially recorded in the empty SRR shown in Fig. 2C. Therefore, the partially recorded SRR has a start address and an end address. Since the data is partially recorded in the SRR of the partial record, the LRA of the partial record SRR represents the last address (at which the normal user profile is recorded), and the NWA is the next writable of the LRA. Address. In the open SRR shown in Fig. 2D, if the SRR is partially recorded, an enlarged view of the broken line portion in Fig. 2D illustrates the relationship between the LRA and the NWA related to the padding operation. Since it is the same as the description board of Fig. 2B, a detailed description about this feature is omitted here. Therefore, referring to FIGS. 2A to 2D, the open SRR of the present invention can be classified into an unrecorded open SRR (Fig. 2A and 2C) and a partially recorded open SRR (Fig. 2B and 2D). . The partially recorded open SRR (Fig. 2B and 2D) can be divided into an open SRR that performs the 13 1314727 operation after the LRA and an open SRR that does not perform the padding operation. According to the design of the present invention, for a write-once optical disc, if the number of login data of the open SRR is too large, it is difficult to manage, so the total number of open SRRs is limited to a predetermined number at any given time. For example, in the case of the BD-WO of the present invention, the total number of open SRRs on the optical disc may be up to 16. Information on the number and location of login data for open SRR can be found in the “Open SRR Table” field under the heading of SRRI and an “Open SRR Login Data” field. An "Open SRR Table" field under the heading of the SRRI and an "Open SRR Logging Data Number" block will be described later when discussing the structure of the SRRI with reference to Figures 5 through 6C. Figures 3A through 3E illustrate different types of shutdown SRRs for a write-once optical disc (e.g., a BD-WO) designed in accordance with the present invention. A closed SRR is an SRR that cannot record data (that is, user data). If the SRR is not recordable, the SRR does not have an NWA. Since the SRR is full, a closed SRR may be generated. Also, even if a recordable area is reserved in the SRR, a closed SRR may be generated because a user or a host executes a command to close the SRR. In particular, Figure 3A shows an empty SRR' which is a type of closed SRR. An empty SRR is an open, empty SRR (Fig. 2C) that is closed with a close command and no user data is recorded. Thus, Figure 3A illustrates a closed empty SRR, while Figure 2C illustrates an open empty SRR. 14 1314727 Figure 3B shows a portion of the recorded SRR, which is another type of SRR that is turned off. The partial record SRR shown in Fig. 3B is the open partial record SRR shown in Fig. 20, which is closed using a close command without any additional user data recorded therein. Thus, Figure 3B illustrates the SRR of a closed partial record, while Figure 2D illustrates the SRR of an open partial record. Figure 3C shows a completed SRR, which is another type of closed SRR. The completed SRR is an SRR where the user profile is full or it is filled with dummy data. The completed SRR exists only in the closed SRR. Figure 3D shows a closed partial record SRR, which is another type of closed SRR. When the open partial record SRR shown in Fig. 2D is closed, the partial record SRR shown in Fig. 3D becomes an SRR in a recordable area after the LRA is filled with dummy data. Therefore, the SRR can be filled with virtual data as padding data after its LRA or all recordable areas of the NWA or only certain recordable areas (e.g., one or more clusters). In addition, when filling certain areas, a special character encoding (for example, an ASCII character set) can be recorded as a padding data instead of a virtual data record to indicate that the SRR is off. In this case, the special character code used to fill the data may be a character such as "C L S D ", which indicates that a corresponding SRR is off. Figure 3E shows an empty SRR, which is another type of SRR that is turned off. When the open null SRR shown in Fig. 2C is closed, the work SRR of Fig. 3E is not a work-filled SRR that fills the recordable area after its LRA with virtual data and then closes. Therefore, the SRR can be filled with dummy data as a padding material after it has a full or recordable area or only some recordable area (e.g., a set). In addition, when filling certain areas, a special character encoding (such as an ASCII character set) can be recorded as a padding data instead of a virtual data record to represent S R "R ^ gn

疋& In this case, the special character code used as the padding material may be a character such as "CLSD" which indicates that a corresponding SRR is off. _ If the closing srr shown in the 3D and 3E figures is all filled with dummy data to its end address, the completed SRR of the closing = 疋 and the 3C drawing shown in the 3D and 3e are The same SRR. In other words, in the present invention, when the open SRR is turned off (by closing the "decrease"), the method for determining to close the s RR type is to define the closed SRR to be divided into the following two cases: The padding operation is not performed to close the remaining areas where the SRR is not recorded (Figs. 3A and 3B), and the other case is to perform the padding operation and close the remaining areas where the SRR is not recorded (Fig. 3D and Fig. 3E). Further, in the present invention, when an SRR is turned off, the SRR may be turned off without performing a padding operation, or the SRR may be closed by filling with a special padding material. Although only the SRR or unrecorded area has performed the padding operation, 'Blu-ray discs are considered to be compatible with only one disc recording and playback device during playback (eg, as shown in Figure 12) can be selectively filled 16 1314727 The disc, the sample, further ensures the freedom of designing the recording and playback device. When the optical disc is filled, a recording and reproducing portion of the recording and reproducing device (for example, the component 1 in FIG. 12) can automatically record the special material, so that the component 接收 receives a special material from a controller 20 and can solve the problem. Fill in the problem of operation. 4A and 4B illustrate some examples of padding identification information designed in accordance with an embodiment of the present invention when a closed (four) and an open SRR of a write-once optical disc are respectively filled to fill the virtual f-material. When off-open SRR, the fill operation can be performed on the open SRR. However, it is also performed in response to a - open SRR in response to a command without closing srr (for example, as shown in Figures 2B and 2D). That is to say, the Fig. 4A map is associated with the 2B map or the 2D map and the 4B graph is associated with the Fig. 3 or Fig. 3E. More specifically, Figure 4A illustrates a situation in which an open SRR is in which actual user data is only recorded in certain areas of a cluster, and the rest of the cluster is filled with dummy data. Figure 4a shows the padding identification information used to distinguish a magnetic region in which the actual user data is recorded from one of the magnetic regions filled with dummy data. The Padding_flag is set to the corresponding cluster. Control data in. There are 32 padding flags here, each padding flag corresponding to one of the 32 magnetic regions in the cluster. As shown in Fig. 4A, in this example, because the magnetic region is 〇_magnetic The area 29 is the area in which the user data is recorded, so the padding flag of each magnetic area is set to 17 1314727 as a value (for example, "0 b ") to indicate that no data is filled in the corresponding magnetic area. Since the magnetic zone 3〇 and the magnetic zone 31 are areas where the data is filled', the padding flag of each magnetic zone is set to a value (for example, lb) to indicate that there is padding data in the corresponding magnetic zone. In this example, LRA represents the position of the magnetic zone 29 (first PSN). Thus the 'optical recording and playback device can decode a cluster containing LRA, read the padding flag corresponding to each magnetic zone, and then accurately identify a magnetic field. District (here, user profile In this cluster, it is recorded from one of the magnetic regions filled with virtual data.) Figure 4B illustrates the case where a special cluster of recordable areas in an SRR is filled with dummy data for a closed SRR. Figure 4B shows The padding identification information "Padding_flag" (used to distinguish between a closed SRR without padding and a SRR with padding after padding) is set to the control flag of the corresponding cluster. As shown in Fig. 4B, in this example, because of the magnetic region The 〇-magnetic region 3 1 is an area filled with dummy data, and the padding flag is set to a value for all magnetic regions (for example, " lb " ). Therefore, as described above, the optical recording and reproducing device can have a padding recognition. A cluster of information (filling the flag) decodes, reads the padding flag corresponding to each of the magnetic regions, and then accurately identifies all the magnetic regions filled with the virtual material in the cluster. In other words, FIG. 4A and The padding operation for terminating the sequential recording on the disc is related to 'the 4B picture and the padding operation for closing an SRR. FIG. 4A illustrates that when the sequence recording is terminated, in the relevant cluster 18 13 All other magnetic regions of .14727 are virtual data colonies, and if the corresponding magnetic H sleeves/fill operations, each padding flag corresponds to u stubling', in the cluster's spare area, and is set to " Lb". In the case of Figure 4A & g, the magnetic field is occupied by the filling. On the other hand, the flute is on the case of Figure 4B and t is filled when the SRR is turned off. One or more clusters of A ° results (sub-cluster). For the filling of the set, corresponding to this cluster 32 magnetic zone, -?, 32 2 fill flag is set to "lb" to represent this cluster Filling in 3: The feeding is the same as in Figure 4B. 1 ^ ~ -X ) a "section", 熹 spleen, 一 an instance of a segment of a higher-level credit-recording disc for an upper unit and a lower recording unit (eg, an SRR, , ) In comparison, it contains at least one SRR. A plurality of segments can be recorded on the first, and such a disk is called a multi-session optical disc. The present invention will now refer to the concept of the U.S. section. First, the present invention can allocate a plurality of segments from the inner track of the optical disk to the outer track of the 70 segments, and the segment numbers are assigned to the segments in a given order. Even if there are multiple segments' In a certain time - there can only be one open section on the disc. This open section is ugly. The section with the highest serial number in the existing section. In other words, in a certain _ The section formed at the outermost track for a predetermined period of time is a recordable section, referred to as an open section. When the recording is completed or a close command is received, the currently open section is closed. Become a closed section. All SRRs in the closed section should be off 'Become a closed SRR. 19 13.14727 Here, if the section to be closed contains an invisible SRR, then the corresponding: visible SRR is not included in the closed SRR, only the rest of the curry is closed. Then ' $ The invisible SRR included includes a new open section. In Figure 4C, 'as an example, a section #1 indicates a closed section' - section #2 represents an open section. Segment #1 consists of -SRRH and an SRR#2, and section #2 consists of a srr#3, a coffee#4, and an SRR#5, etc. As mentioned above, when the segment is closed, the SRR is also The closed 'srr can be closed after the padding operation is performed or is not performed without performing the padding operation. The identification of whether the padding operation has been performed is identified by "filling the flag 〇 > adcHng_flag". When - the unfinished _ is closed Only the prison-recorded area is closed, and the _unrecorded area becomes the open section of m SRR with % 胄. There is no special buffer between the - section and the other-contiguous section. Instead, provide _ "segment open, · session plus t (10) in SRRI It indicates whether the corresponding SRR is the beginning segment. The sector gate start bit will be described in detail later (when describing the structure). Although the plurality of SRRs may exist in the open (four) segment (for example, segment #2 shown in the figure π.), all the SRRs of this segment are opened.

At least the open 峨 in the open section is sufficient. In the open section #2 of Fig. 4C, 'SRR J疋 belongs to the open SRR, and SRR #4 belongs to the closed SRR. Figures 5 through 6C illustrate a coffee structure 20 1314727 and information contained within the SRRI designed in accordance with the present invention. In particular, Figure 5 illustrates the overall structure of an SRRI. SRRI is about one or more srr, and SRRI is management information (used to provide the recording status of the disc). In the optical disc structures shown in Figs. i and 5, the SRRIs are recorded in (these) TDmas (e.g., TDMAO). As shown in Fig. 5, each SRRI 60 in the TdmA is composed of three parts: a header 50, an SRR registration data table 30, and an SRR table terminator 40. Title 50 identifies the SRRI. The SRR login data table 30 indicates the recording status of each corresponding SRR. The SRR table terminator 40 indicates the end or termination of the SRRI. The title 50 is located at the head of the SRRI and contains an "SRRI structure identifier: SRRI structure identifier" booth 51, a "List of opened SRRs: open SRR table" block 52, and a "Number of SRR entries: SRR The number of login data "blocks 53," and a "Number of opened SRRs: open SRR number" field 54. So, before reading the SRR login data sheet, you can check the entire contents of the SRR login data. Therefore, the SRRI Structure Identifier field 5 identifies the SRRI. The "open SRR table" block 52 informs the location (identification flag) of the open SRRs associated with the corresponding SRRI, and a more detailed description (see Fig. 6C) will be described later. The ''s R R Login Data Number' field 53 indicates the total number of srrs associated with the SRRI 60. The "Open SRR Sequence Number" field 54 indicates the total number of open SRRs.

After the title 50, the SRR registration data sheet 5 is recorded in SRRI 21 13,14727. After the last SRR login, the end of the SRRI is marked with the SRR table terminator 40. If the capacity of the SRRI is variable, the SRR table terminator 40 is a meaningful piece of information indicating an end position of the corresponding SRRI. Therefore, as the management information of the optical disc, the SRRI is composed of the title 50, the SRR registration data table 30, and the SRR table terminator 40. Whenever an update is made, all such information is recorded in batches. Figure 6A illustrates an example of an SRR login data table 30 (recorded in an SRRI) designed in accordance with the present invention. As shown in Figure 6A, the SRR login data table 30 is composed of one or more SRR login data 35. Each SRR login data 3 5 transmits the information of an SRR (identified by the SRR sequence number) on the optical disc, and its capacity is 8 bytes (6 4 bits) to indicate the recording status of the corresponding SRR. Each SRR login data 3 5 includes a status field 3 1 (state 1), a start address field 3 2, another status block 3 3 (state 2), and a last recorded address (LRA) field. 34. The status field 3 1 is used to store the corresponding S RR status; the start address block 3 2 is used to store a starting address of the corresponding SRR; the other status field 33 (state 2) is used to store the corresponding The state of the SRR; the Last Recorded Address (LRA) field 34 is used to store the LRA of the corresponding SRR (e.g., the end address of the user profile stored in the SRR). Typically, the starting address of the corresponding S RR in the start address field 3 2 is represented as a physical magnetic sector number (PSN). According to an embodiment, the first 4 most significant bits (bit 63-bit 60) of the SRR login data 35 (64 bits) are assigned to the first status field 3 1 and the next 28 bits from the 13.14727 (bit 59·bit 32) minutes; match, D start address field 3 2 and then the next 4 bits (bit 31_bit 疋 28) are assigned to the second state clamp 33, The last 28 bits (bit 27彳fr - 兀27-bit 兀0) are assigned to the lra block 34 °. Figure 6B illustrates the SRR login data 35 of the month sigh according to the present invention (recorded in the SRR login data table) One of 30)

Ά 1J Status 1 Field 3 1 is used to store information to identify whether any fill gestures are performed in the corresponding SRR 魇MR. State 2 Block 33 is used to store the gift, π Ά ^ to identify whether the corresponding SRR is the beginning of a segment. - As shown in Fig. 6B, in the first four headers assigned to the state 1 position 31, one element is used to store the padding identification information ''flag, to identify whether the padding data is in progress. The other three of the four digits are reserved as any modification to the standard.

It should be noted that the identification information "P

The target (recorded in the SRR login data) is similar to the padding identification criteria (see Figure A and Figure 4B for a description). However, the door has a different purpose. The special SRR is finally filled, then

The ~f kickmark is broken in the SRB login data to directly indicate that the corresponding coffee is _filled. Therefore, 'by checking the P-flag (recorded as the management information of the SRR login data), the optical recording device (12th round) can check whether the corresponding SRR has been filled by the & operating. Referring to FIG. 4A and FIG. 4Risi - , ^ shows the 4J3 diagram 'After then, the optical recording and reproducing apparatus as described above decodes the phase 庳 相 7 phase m srr, and reads from this cluster corresponds to SRR per The magic padding flag value of a magnetic zone, so that the optical recording 23 1314727 device can determine how many SRRs perform the padding operation after its LRA" In the example shown in Figure 6B, the state 1 pad 3 i The first one (31a) transmits the P-flag, while the remaining 3 bits (3 lb) of field 31 are reserved. If the p-flag is equal to lb, it means that the corresponding SRR is a filled SRR. (That is, at least some parts of srr are filled with padding data). If the 1>_flag is equal to 〇b, it means that the corresponding SRR is an SRR that has no data to be filled. State 2's Block 3 3 (which is assigned 4 bits) is used to transmit information (whether the corresponding SRR is the SRR at the beginning of the segment). One of the 4-bit fields 33 transmits a segment identification information "S_flag" to identify whether the corresponding SRR is the start SRR of a segment. The other three bits of block 33 are reserved as any modification to the standard. In other words, the S-flag is the segment start bit described above. In this example, the first bit (3 3 a) of the 4-bit field 3 3 stores the S-flag, and the remaining 3 bits (3 3 b) are reserved bits. If the S-flag is equal to lb, it means that the corresponding SRR is the beginning SRR of a sector. » If the S-flag is equal to 〇b, it means that the corresponding SRR is not the first SRR of a sector. One reason for identifying the beginning of a segment with an S-flag is to provide compatibility with existing optical disc structures, such as DVDs, which allocate additional regions for distinguishing segments (eg, border) -in/border-out). However, the allocation of additional areas reduces the overall recording capacity of the disc. Therefore, the present invention overcomes this limitation by providing section identification information (S-flag) at the SRR login data 35. Therefore, the area identification in the SRR registration material 35 is used instead of allocating additional information. The segment structure of the entire optical disc can be identified by the segment identification information S-flag to be easily stored in such a segment to separate the individual status information (stored in _) described in the present invention, but they can also be stored together. In the bit. Conveniently, the P-flag and s_flag are described as separate status of the SRR login data. There is a status of the SRR login data. The LRR rogue 34 of the SRR login data 35 is used to record the user data in the corresponding SRR. The End Address (LRA) field and an end address that stores the user data (without any padding data) recorded in the corresponding SRR. Figure 6C illustrates a detailed structure of the SRRI "Open SRR Table" field 52, represented in Figure #, designed in accordance with an embodiment of the present invention. The information stored in field 52 is used to determine the location or identification information for each open SRR. As shown in Fig. 6C, one or more open SRR numbers are recorded in the "Open SRR Table" field 52 as location information for the open SRR. Two bytes are allocated to record the open SRR sequence number 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 open SRR login data) is recorded with each open Srr sequence number. Therefore, when the 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 according to the SRR information of the present invention. In other words, it should be known that the location of the SRR is open on the current disc to record the data. Since there is no specific information provided in the SRR login data (identifying whether a corresponding SRR is an open SRR or a closed SRR), the location or identification information of the open SRR is recorded under the SRRI title and can be easily Access, so the optical recording and playback device can easily read the SRR login data (related to the identified open srr information). Therefore, only the SRR with the SRR sequence number (recorded in the "Open SRR table, the Palme position 52" can be additionally recorded as an open SRR. After that, if the SRR transitions to a closed SRR, the closed SRR The serial number is cleared from the "Open SRR Table" field 52. Thus, it is possible to easily distinguish between the closed SRR and the open SRR. According to the present invention, a method of updating the SRRI (used to indicate the recording state of the optical disc) will be described. In particular, a method will be described with reference to Figures 7A through 1 1 B to open and close the SRR and segments, fill a SRR with virtual data, and record the SRRI. The recording state of the optical disc in the optical disc, FIGS. 7A to 11B illustrate a method of sequentially recording the SRRI. More specifically, the 7A to 11B drawings sequentially illustrate how different types of SRR are generated on the optical disc. (as shown in Figures 2A through 3E), and how to use the sequential steps to perform SRRI recordings in a sequential flow. As discussed in Figures 1 through 6C, these methods are implemented with SRR. , SRRI, and this The write-once disc of the disc structure (for example, 26 13.14727 BD-WO). Figure 7A shows step i, where the entire area of the disc can be recorded as an initialized empty disc, and one with a thick arrow. The part is marked with the position of the NWA. The starting position of the disc is NWA. Here, there is only one SRR (SRR #1) on the disc. As shown in Figure 2A, this is an invisible SRR. Therefore, one area The segment is in the initialization state of the disc, in which there is only one open segment > 1. The disc is an empty disc, and the SRRI is not recorded on the disc. Figure 7 shows step 2, where the data (such as user data) Partially recorded in the empty disc shown in Figure 7, but section #1 is not yet closed. Here 'On the disc there is only one SRR (SRR #1), as shown in the figure 'is unfinished SRR. Section #1 remains open. Section. As shown in Figure 7B, 'User Profile is recorded in an unrecorded portion of SRR #1 (cluster) in part of SFR #1 not completed (eg ( The magnetic regions are filled with dummy data. As described above, the magnetic filling of the SRR Department with

Padding_flag = lb" indicates that this flag is recorded in an already marked area of the cluster (eg 'in this cluster or padding area'). Figure 7C shows the disc as shown in Figure 7:8 In the state, an SRRI_program is recorded in the management area of the disc. For the convenience of explanation, in all the different knives of the disc structure # srri structure shown in Figs. 1 and 5, only the different knives are removed. Some parts. For example, although (srri + TDDS) or (TDFL + TDDS) is recorded in each cluster of TDma 27 13.14727 (for example, in the TDMAO of the disc discussed above), for the sake of clarity In the tdMAO of Fig. 7C, only SRRI is drawn, and TDFL and/or TDDS are omitted. Further, in the different intercepts of the SRRI as shown in Fig. 5, 'only open' is opened. The SRR table "field 52 and SRR login negative material table" is 3 feet. The disc recording state shown in Fig. 7C is the case where only one open SRR (SRR #1) exists in all the disc regions as shown in Fig. 7B. As shown in Fig. 7C_, when the unfinished SRR #1 is formed without closing the section (as shown in Fig. 7B), SRRI #1 (60a) belonging to Srr #1 is in TDMA0. Generated and recorded. The SRR sequence number (SRr #1) of the open SRR #1 in SRRI #1 (60a) is recorded in its "open SRR table" block 52a. In the SRR #1 (60a) SRR Login Data Table" block 30a, there is only one srr login data 35a (belonging to the SRR#1pSRR login data 35a (or the SRR login data 35b-35p which will be discussed below)) The SRR login data structure of tf as in the 6A and 6B diagrams discussed above. In the SRR login data 35a 'because some parts of Srr #ι are finally filled, the P-flag is set to " Lb" as the status information of the corresponding SRR #1. Since SRR#1 is the starting SRR of the open section #1, the S-flag is set to ''lb'' as the status information of the corresponding srr #1 Figure 8A shows step 3 'here, the section close command is received and executed in step 2 of Figure 7B. As a response to the section 13.14727 for the section close command, the area (with user profile recorded on it) ) is divided into a separate closed SRR, and a new section is generated in the area (immediately in the user data recording area). For example, as shown in Figure 8A, in step 2, the user data is completely recorded. The area portion is now turned into a completed SRR # 1 (closed SRR), which in turn forms a closed section #1. In addition, the unrecorded area becomes an invisible SRR #2 (open SRR), and it is instead formed into an open section# 2. Figure 8B illustrates a procedure for recording the disc recording status (SRRI) as belonging to the disc state as shown in Fig. 8A. Since this SRRI is the second record SRRI, this SRRI is called SRRI #2 (60b) In the TDMAO, 'SRRI #2 (60b) is recorded immediately after SRRI #1 (60 a). For the recording of the disc status shown in Figure 8A, since the entire area of the disc has only one open SRR (SRR #2) and only one closed SRR (SRR #1), so the SRR sequence number of the open SRR #2 is recorded in the "Open SRR Table" block 52b of SRRI #2, and SRR #1 and The information related to SRR #2 is recorded in the "SRR Login Data Table" block 30b of SRRI #2 (as SRR login data 35b and 35c, respectively). In Figure 8B (and in other figures), it is shaded. Srr and recorded data (for example, 35b) indicates that this is a closed SRR login. Because the user data in this newly generated SRR #2 Not recorded, so 81^#2 login data (35<〇p_flag is set to ''仉.) And because SRR#2 is the beginning of open section #2, say #2 login data ( The S-flag of 35c) is set to "lb". 29 13.14727 Figure 9A shows step 4, where the two open srr are additionally retained when the disc is in the form of cancer not seen in Figure 8a. Open section #2 to record the latest information. Therefore, the newly generated open SRr is an open null SRR #2 and SRR #3, and the NWA is indicated by a thick arrow. The result 'open sector #2 consists of empty Srr #2 and SRR #3 and an invisible SRR #4. Fig. 9B is a diagram showing a procedure for recording the recording state (SrRI) of the optical disc, which is related to the state of the optical disc shown in Fig. 9A. Since this SRRI is the SRRI of the third record, this srri is called SRRI #3(60c). SRRI #3 (60〇 is recorded in 311111#2 (6013) adjacent to Ding〇^[0]. For the recording of the disc status shown in Fig. 9A, since the entire area of the disc has three open SRRs (SRR #2, SRR #3, and SRR #4) and a closed SRR (SRR #1), so the SRR sequence numbers (SRR #2, SRR #3, and SRR #4) of the open SRR are recorded in SRRI #3. The "Open SRR Table" block 52c. Information related to all four SRRs (SRR #1 -SRR #4) is recorded in SRRI #3's "SRR Login Data Table" block 3〇c, respectively As the SRR login data 35d-35g. Therefore, because the information related to the newly generated SRR #2, SRR #3, and SRR #4 is recorded in SRRI #3 (60c), in s RR #2, SRR #3 And there is no recorded user data in SRR #4, so the corresponding SRR login data 3 5 e, 3 5 f and 3 5 g P-flags are set to "丨b". However, because SRR #3 and SRR #4 is not the start SRR of open section #2 (SRR #2 is the start SRR of the zone), so SRR #2 login 30 13.14727 material 35e, SRR #3 login data 35f and SRR #4 login data 35g The S flag is set to "1 b ", respectively 〇b ', and "〇b". Figure 10A shows step 5 'here, the user profile is recorded in the empty SRR #2 and invisible SRR #4 shown in Figure 9A. Therefore, the first empty The SRR #2 transition becomes part of the recorded srr #2, and the invisible SRR #4 transitions to an unfinished srr #4, but the second open empty SRR #3 is unchanged. SRR #2 does not perform the fill operation To record user data, SRR #4 is recorded with user data and filled with padding data. In the padding area of SRR #4, the 'fill flag is set to '丨b". Figure 10B shows the recording disc. A program for recording the status of the disc as shown in Fig. 10A. Since this SRRI is the SRRI of the fourth record 'This SRRI is called SRRI #4 (6〇d). SRRI #4(6 0d) ) is recorded adjacent to SRRI #3 (60c). For the recording of the disc status shown in Fig. 10A, 'because the entire area of the disc has three open SRRs (SRR #2 - SRR #4) and one off) SRR (SRR #1), so the SRR sequence number (SRR #2 _SRR #4) of the open SRR is recorded in the "Open SRR table" of SRRI #4 (60d). Bit 52d. The information related to all four SRRs (SRR #1 - SRR #4) is recorded in SRRI #4 (60d) "SRR Login Data Table" block 30d, which is used as SRR login data 35h-35k. In this step, the number of SRR login data and the open srr location are the same as those shown in Figure 9B, but since the user profile is recorded in a special open SRR, it is recorded in the open SRR login. 31 1314727 The LRA of the material was changed, and the value of the P-flag was also changed. In other words, the information recorded on SRR #2 and SRR #4 is updated. Since SRR #2 records the user data but does not perform the padding operation, the P-flag of the SRR #2 login data 35i is kept at "Ob". Since SRR #4 records the user data and also performs the padding operation, the P-flag of SRR #4 login data 35k is modified to "lb". Further, since the state of the section #2 has not changed, the S-flags in the registration materials 3 5 h - 3 5 k of the S RR are the same as the SRR registration materials described in the 9B diagram. Fig. 11A shows a step 6, in which a sector close command is received and executed when the optical disk is in the state shown in Fig. 10A. As shown in FIG. 11A, the section #2 is changed from an open section to a closed section #2, and all SRRs of the section #2 are also closed to become closed SRR #2 to SRR #4. In particular, the extra recordable portion of the open SRR is filled and closed with dummy data. All additional recordable parts 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 material (e.g., "CLSD" as a character encoding) can be recorded as padding as described above. The previously opened SRR #2, SRR #3, and SRR #4 become a closed partial record SRR #2, a closed empty SRR #3, and a completed SRR #4 (turned into a closed area) Section #2). In SRR #2 and SRR #3, there are additional recordable areas that are preserved (but become a closed SRR by a shutdown command). Here, some parts can be filled with dummy data as an alternative. Therefore, all the magnetic regions filled with dummy data in this cluster or SRR (for example, as shown in Fig. 4B) are set by padding flag Padding_flag = lb. However, even in this case, the LRA recorded at the SRR registration data indicates an end bit (user data is actually recorded at this end position). As mentioned above, the virtual data portion has no effect on determining the LRA location. The remaining outermost SRR #5 is an invisible SRR #5, which in turn forms a new open section #3. Fig. 11B is a diagram showing a procedure for recording a disc recording state (SRRI) relating to the state of the optical disc shown in Fig. 11A. Since this SRRI is the SRRI of the fifth record in the management area, this SRRI is called SRRI #5 (60e). In TDMAO, SRRI #5 (60e) is recorded adjacent to SRRI #5 (60d). For the recording of the disc status shown in Figure 11A, because the entire area of the disc has an open SRR (SRR #5) and four closed SRRs (SRR #1 - SRR #4), the open SRR (SRR) #5) The SRR sequence number is recorded in the "Open SRR Table" block 52e of SRRI #5' and all previously opened SRR numbers recorded in SRRI #4 (for example, SRR #2 in Figure 10B) SRR #3 and SRR #4) are eliminated from the currently open SRR table 52e. Eliminating SRR from the "Open SRR Table" block means that such SRRs have been closed. Information related to all five SRRs (SRR #1 -SRR #5) is recorded in the "SRR Login Data Table" field of SRRI #5, which is used as SRR login data 351-35p. Because SRR # 2 and SRR #3 are filled with dummy data (in response to the closing command of 33 1314727), so the P-flags of the SRR #2 login data 35m and SRR #3 login data 35η are converted to " Lb" to indicate that at least a part of the corresponding SRR is filled with padding data. Since the LRA of an SRR login data is an end position (user data is actually recorded at this end position), SRR #2 to SRR #4 The LRA is equal to the value of the LRA previously recorded in SRRI #4 (60d). In addition, 'the user data is not recorded on the newly generated invisible SRR #5', so the P-flag at 35p of the SRR #5 login data It is set to “Op.” Since SRR #5 is the SRR of the beginning of new section #3, the S-flag of SRR #5 login data 3 5p is set to “lb” ° from 7A to 11B It can be seen that SRRI is information indicating the recording status of the current disc. When the disc is loaded and recorded During standby, the recording and playback device checks the latest SRRI (SRRI #5 in the above example) that was last recorded in the management area. Therefore, it is possible to accurately understand the current disc recording status (included in a recordable area on the disc or The location of the SRR. Therefore, the expected user profile can be recorded in a recordable area of an open section on the optical disc. Figure 12 illustrates a disc recording and playback device designed in accordance with the present invention. The device or system can be used to implement the solar cell structure and/or SRRI structure and method thereof as discussed herein. Figure 12, the disc recording and playback device includes a recording and playback unit 1 (for recording and (or , && reproduce data to (from) disc and a controller 20 (for controlling the playlist + 1). All components of the recording and playback device are operatively coupled 34 13.14727 I. Controller 20 pairs Yu #,上,来录 enemy unit 10 sends a command to record and/or I number from (to) a special area (such as one of the SRR or a section on the disc)彔Release unit 1 〇 according to control The command of 20 records and/or reproduces the data to the (self) optical disc. The recording and playback unit 10 includes an interface unit 12, a disc reading unit 11, a data processor 13, a servo unit, and a memory. 1 5, and - micro-power (four) 16. The interface unit 1 2 is responsible for communication with the door of an external device (such as the controller 20). The optical disk reading unit u directly records or reproduces the data to the (self) optical disk. The data processor 13 receives a reproduction signal 4 from the optical disk reading unit u, and modulates a signal to the optical disk and transmits a signal. The servo unit 14 controls the optical disk reading unit 11 to read the letter I from the optical disk or record the signal to the optical disk. The memory 15 temporarily stores data and various information (including management information discussed herein). The microcomputer 16 controls the components of the recording and playback unit 10. Since the recording and reproducing apparatus as shown in Fig. 12 can selectively perform a padding operation, the designer can more freely design the recording and reproducing apparatus. When a padding operation is performed, the recording and playback unit 1 can automatically store a special police psychology. The methods of recording and playing back data on a disc can be divided into two categories. One type is the case shown in Figure 4 to Figure B, involving a method: completely recording data on an open SRR, forcibly filling the remaining magnetic regions in the middle (including LRA), and when closing an SR ^, , b - recorded information to identify whether the remaining magnetic regions have been filled or rooted. *, sub-data to confirm whether the cluster has been filled and the padding identification information is recorded. 35 1314727 The second category is The method of closing all S RRs in a section when the section is closed. No special buffer is provided between a segment and its adjacent segments. The starting position of the segment (i.e., the S RR at the beginning of the segment) is identified by segment identification information (e.g., S-flag). A method of recording and reproducing a disc designed in accordance with an embodiment of the present invention will now be described in detail. When a disc (e.g., a B D - W 0) is loaded into a recording and playback device (e.g., a device as shown in Fig. 12), the latest srri is read as the latest disc management information recorded in a TDMA. Further, the SRRI title and SRR registration data recorded in the latest SRRI are read out and temporarily stored in the memory 15 of the recording and reproducing unit 10. The stored SRRI indicates the latest disc recording status. The header information through the SRRI can be used to identify these open srRs. Through the SRr login data, the data can be recorded on the entire area of the disc, or the non-recorded status and open sections can be checked for presence, as well as the location of the unrecorded status and open sections. Also, it can be identified whether the sRR has performed a padding operation. All such information can be used when the disc is recorded and played. The 'data (eg user profile) is then recorded in a special open SRR. When the data is completely recorded in the open srr, the unrecorded magnetic regions (including LRAs) in this cluster are filled with dummy data (eg 'for stability and robustness'), padding identification information Padding_flag is set Is "lb". For each padding area, padding identification information paddi.ng-fiag is set to 36 1314727 lb for each magnetic zone. If the magnetic area is not filled, the corresponding padding_flag is set to "Ob". Also, when the SRR login data in the SRRI is updated, the SRR status information P-flag is set to '' lb' to indicate that at least some portions of the corresponding SRR have performed the padding operation. The controller 20 issues a segment close command to allow all SRRs in the segment to be closed and another case where the SRR is issued by the controller 2() and only the corresponding SRR is turned off. The computer 16 can select whether to close a recordable area (eg, a cluster) on the closed SRR after performing the padding operation or when the padding operation is not performed. For the above case, a designer can design the recording and playback unit 10 automatically. The padding is used to fill the SRR, and the SRR is unconditionally turned off by the controller 20 without executing a padding command. The above function is referred to as the "auto-fill function" performed by the recording and playback unit. Compared with the case where the recording and playback unit 1 receives the dummy data by a padding command and fills the SRR thereafter, the automatic padding function more effectively reduces the padding operation time. Further, if the padding operation as described above is performed When the state of the SRR is changed, the Padding_flag is set to lb according to each padding area. Furthermore, the p flag of the corresponding srR login data is set to ib. Such information can be used by a variety of different recording and playback devices. Further, the S-flag at the beginning of a new open section is set to lb' at the corresponding SRR registration data to indicate the starting position of the open section. Therefore, 'SRR type and SRR definitions defined by the present invention are provided, 37 1314727 and, as defined, 'there are various optical discs that have the SRR, including the SRR, which is included in the method of the transmission, the SRR is closed, Padding_flag P-flag and section in. Therefore, the information can be effectively changed, changed and changed. The scope of the patent application is modified and changed. [The figure is simply an example of a patent application, it and the description: Figure 1 is a method for recording SRRI in the SRR type and definition of write once. Various recording and playback devices, such as desired performance, can be used to access the recording management resources for write-once optical discs that are currently designed: define new SRR types and segment types. If the padding operation is performed, or if the padding operation is performed, the padding identification information is appropriately set and recorded in the padding area. Other padding identification information The identification information S-flag is recorded in the SRR login data in a write-once optical disc with a new physical structure, managing the location record and management.
