Referring to FIG. 1, in a single recording layer once recording information storage medium 100, a lead-in area, a data area, and a lead-out area are provided in the circumferential direction from the inner circumference. The lead-in area includes finalized disc management area 1 (FDMA1), FDMA2, and recording management data area 0 (RMD area 0). The data area includes a spare area 0, a spare area 1, and a user area. The lead out area includes FDMA3, FDMA4, and RMD area 1 similarly to the lead in area.

The RMD area is an area for recording recording management information (hereinafter referred to as "RMD") according to the present invention. RMD is mentioned later.

The spare area is an area allocated to replace and rewrite the defective user data when a defect occurs in the user data recorded in the user area. In the present embodiment, the spare area is allocated to the data area once by the data recording and / or reproducing apparatus or by the user's choice upon initialization of the recording information storage medium 100.

In the present embodiment, in addition to user data rewritten for defect management, temporary defect management information (TDDS: Temporary Disc Defect Structure) and temporary defect information (TDFL: Temporary DeFect List) are recorded in the spare area.

The TDDS may include a temporary defect management information identifier, an update count, location information in which final temporary defect information is recorded, location information in which final disc and drive information is stored, size information of a spare area allocated to a data area, and the like. .

In the dual recording layer medium 200 shown in Fig. 2, the RMD areas are used in the order of RMD area 0, RMD area 1, RMD area 2, and RMD area 3. By defining the order of use of the plurality of RMD areas and the direction of use of each of the RMD areas, the data recording and / or reproducing apparatus can access the finally updated RMD in the dual recording layer medium 200 more quickly and easily. Can be.

4 is a diagram illustrating an RMD format for a sequential recording mode according to an embodiment of the present invention. Referring to FIG. 4, the RMD 400 according to the present embodiment includes an RMD Header 410 and a List of R-zone entries 430.

The RMD Header 410 includes RMD identifier 411, last border entry 413, and total number of borders 415. The RMD identification information 411 is information for distinguishing each RMD recorded in the RMD area, and the last border entry 413 is a plurality of data areas provided in the data area of the recording information storage medium once according to the present invention. Information indicating the position and state of the last used border. The number of borders 415 means the total number of borders provided on the recording information storage medium once.

The recording information storage mediums 100 and 200 according to this embodiment are used continuously in units of borders according to the direction of use of the user area. The last border is a border used last among the plurality of borders provided on the medium based on the direction of use. Therefore, only the last Border can always be an open border, and all borders before the last border are closed.

FIG. 5 is a diagram illustrating an example of the Last Border entry 413 illustrated in FIG. 4. The last border entry 413 shown in FIG. 5 includes status information indicating the state of the last border, a start address of the last border, and a last recorded address (LRA) which is a last address where data is recorded. The start address is the physical start sector address of the border. LRA is the physical sector address of the last location where data was recorded in the border.

The state information of the Last Border entry 413 is information indicating whether the Last Border is in an open state capable of recording new data in a sequential recording mode or a border dedicated for reproduction in which new data cannot be recorded. As will be described later, this state information is only for the Last Border and does not include the state information in the entries of the closed borders.

On the other hand, the number of borders 415 of FIG. 4 represents the starting R-zone entry number of the Last Border in the RMD 400. As will be described later, when the last border is closed, at least one R-zone included in the last border is merged so that one border becomes one R-zone.

FIG. 6 is a diagram illustrating an example of a list of R-zone entries 430 shown in FIG. 4. Referring to FIG. 6, List of R-zone entries 430 includes List of close border entries and List of R-zone entries of open border. List of close border entries indicates BORDER ENTRY # 1 to BORDER ENTRY #k (k is an integer greater than or equal to 1), which is an entry of borders used before creation of the last border which is open.

List of R-zone entries of open border are R-ZONE ENTRY # (k + 1) to R-ZONE ENTRY # (k + n) (k and n) An integer of 1 or more). Each BORDER ENTRY and R-ZONE ENTRY contains the start address and LRA of each BORDER and R-ZONE. Unlike the last border, it does not contain status information. The reason for including status information only for the Last Border is that it is not recorded in the border which is already closed, and is used only for playback, so it does not matter in which recording mode. Furthermore, closing the Last Border means that the medium is finalized and used only for playback.

Referring to the List of R-zone entries 430, the data area of the recording information storage medium 100 and 200 once according to the present embodiment includes k closed borders, and the Last Border is divided into n R-ZONEs. It can be seen that. As described above, each time the last border is closed, each closed border is composed of one R-zone since at least one R-zone included in the last border is merged into one R-zone.

The data recording and / or reproducing apparatus can know from the total number of borders 415 shown in FIG. 4 that the total number of borders is k + 1, and the (k + 1) th R-ZONE ENTRY is the last border. It can be seen that the start of R-ZONE ENTRY. The data recording and / or reproducing apparatus can know the location where the starting R-zone entry information of the last border is stored in the RMD format using the total number of borders and the starting R-zone entry number of the last border.

That is, the position in the RMD format where the first R-zone entry information in the Last (Open) Border starts can be calculated by Equation 1 below.

Last (Open) Starting position of the first R-zone entry information in the Border = (length of one Border entry * ("Total number of Borders" -1)) + (starting position of "List of close Border entries") )

As described above, by having a border entry having a start address and an LRA for each border, the start address and the LRA for each border can be known, so that the data recording and / or reproducing apparatus can be used as a recording information storage medium according to the present invention. Information about the latest file system can be obtained more quickly.

For example, for a UDF file system, the anchor point for a closed border should be at least two of 256, last logical sector number-256, and last logical sector number within the closed border. Therefore, in the case of the UDF file system, the start address and LRA of each border can be known so that the data recording and / or reproducing apparatus can easily obtain the location where the file system is recorded.

Furthermore, when closing the last border, all R-zones within the border are merged into one R-zone to represent as one R-zone entry (Border entry), thereby splitting the Open Border into as many R-zones as possible. Can be. For example, when the size of the RMD format is limited and the number of R-zone entries that can be included in one RMD is 7000, 5000 R-zone entries can be RMD using 5000 R-zones in the first border. If included, the second Border can only use 2000 R-zones. However, as in the present invention, if the border is closed and the R-zones included in the border are merged into one R-zone and represented as one R-zone (= Border) entry, the second border is 6999 R-zones. Can be used to improve the efficiency of media use.

7A and 7B illustrate a data area in which a previous last open border is closed and a new last open border is created according to an embodiment of the present invention.

FIG. 7A shows k closed borders and a (k + 1) th border as the last border in the open state. The last border (k + 1) th border includes (k + 1) th R-ZONE 571 to (k + n) th R-zone 575. In the (k + n) th R-zone, the last R-zone, data is recorded in a sequential manner only from the beginning to a predetermined position.

FIG. 7B is a diagram illustrating a data area in which the (k + 1) th border, which is the last border shown in FIG. 7A, is closed, and the (k + 2) th border, which is a new last open border, is generated. From the (k + 1) th R-ZONE (571) to the last position where the data of the (k + n) th R-zone (575) is recorded, it is merged into one R-zone so that the (k + 1) th border is do. That is, the (k + 1) th border with the closed position from the start position of the (k + 1) th R-ZONE 571 to the last position where the data of the (k + n) th R-zone 575 is recorded is do.

 FIG. 8 is a view showing an RMD 610 corresponding to the data area shown in FIG. 7A, and FIG. 9 is a view showing an RMD 620 corresponding to the data area shown in FIG. 7B.

Referring to the RMD 620 shown in FIG. 9, once there are (k + 2) borders in the recording information storage medium, the last border entry includes the state information, the start address, and the last border of the (k + 2) th border. LRA is included. When the data recording and / or reproducing apparatus is shown in Fig. 7B, when the (k + 1) th border which is the last last border is closed, and the (k + 2) th border which is the new last open border is generated in the data area, The previous RMD 610 shown in Fig. 8 is updated to generate the RMD 620 shown in Fig. 9, and then recorded in the RMD area. The RMD 620 changes the Last Border entry as the Last Border becomes the (k + 2) th border compared to the previous RMD 610, increases the "Total number of Borders" by 1, and "List of close Border entries". Will be added the entry of the (k + 1) th border.

If the last border is closed once for the finalization of the record storage medium, it is not necessary to create a new last border in the data area. As described above, when the media is finalized, the final media management information such as TDDS and TDFL is recorded in the FDMA so that the data recording and / or reproducing apparatus can determine whether the media is finalized by accessing the FDMA in the future. Alternatively, the final recorded RMD can be obtained, and it can be determined whether the medium is finalized from the state information of the Last Border entry obtained therefrom.

10 is a block diagram of a data recording and / or reproducing apparatus according to an embodiment of the present invention. Referring to FIG. 10, the apparatus according to the present embodiment includes a write / read unit 1, a control unit 2, and a memory 3. The write once information storage medium 10 is a write once information storage medium according to the embodiment of the present invention shown in FIG.

The recording / reading section 1 records and / or reproduces data in the recording information storage medium 10 once under the control of the control section 2. In data recording, the recorded data is read out after the recording in order to verify the recorded data.

The control unit 2 controls the overall operation of the data recording and / or reproducing apparatus according to the present embodiment.

At an initial point in time when the recording information storage medium 10 is loaded into the data recording and / or reproducing apparatus, the data recording and / or reproducing apparatus may be modified such as RMD, TDDS, TDFL, etc., last updated from the recording information storage medium 10 once. The information is read out and stored in the memory 3. Then, in the sequential recording mode, once user data is recorded on the last open border of the recording information storage medium 10 and a need arises for updating the RMD, the control unit 2 stores the recording information once, stored in the memory 3. An updated RMD is generated with reference to the RMD read from the medium 10.

The following describes a method of recording data on a recording information storage medium once according to an embodiment of the present invention, which is performed by the data recording and / or reproducing apparatus shown in FIG.

11 is a flowchart of a data recording method according to an embodiment of the present invention.

Although not separately shown, once the recording information storage medium 10 is loaded into the data recording and / or reproducing apparatus, the initialization for the use of the recording information storage medium 10 is performed once. That is, the controller 2 reads out basic control information for use of the recording information storage medium 10 and finally updated TDFL, TDDS and RMD from the lead-in area and stores them in the memory 3. The control unit 2 obtains the state of the last border, the start address, and the LRA from the RMD. The control unit 2 finds the position where the last updated file system is recorded from the start address of the last border and the LRA, reads it, and stores it in the memory 3.

Once user data is input to the record information storage medium 10 with the user data recording command from the host (not shown) once after initialization for use of the record information storage medium 10 is performed (S810), the controller ( 2) records user data once in a predetermined unit in a sequential recording mode in a specific R-zone provided at the last open border of the recording information storage medium 10 (S830).

The data recording and / or reproducing apparatus generates an updated RMD with reference to a previous RMD read out from the recording information storage medium 10 once stored in the memory 3 at a predetermined time for updating the RMD, and then records the updated RMD in the RMD area. (S850). The structure of the RMD is as shown in FIG.

FIG. 12 is a diagram illustrating an embodiment of step 830 illustrated in FIG. 11. After the user data is recorded in the last open border in R-zone units (S831), when the last open border is closed according to a command of a user or a host, the controller 2 controls the last time the user data was recorded from the start of the last open border. The section up to the position is determined as the last closed border (S833).

The controller 2 merges at least one R-zone included in the last closed border into one R-zone (S835). 7A, 7B, 8, and 9 described above, an understanding of steps 833 and 835 can be understood.

When closing the last open border, as shown in FIG. 9 described above, the controller 2 generates an updated RMD and then writes it to the RMD area of the recording information storage medium once.

Meanwhile, the update timing of the RMD can be determined in various ways. For example, the RMD can be updated by updating the RMD every predetermined period, updating when one recording operation is completed, or updating the amount of user data recorded in the recording information storage medium 10 once a predetermined amount.

Hereinafter, the data reproduction method of the recording information storage medium 10 in which the RMD is recorded will be described according to the present invention.

The data reproducing apparatus according to the present embodiment uses the data recording and / or reproducing apparatus shown in FIG. However, since it is a reproduction-only device, the recording / reading unit 1 corresponds to the reading unit and the control unit 2 will only perform a function related to data reading.

13 is a flowchart of a data reproducing method according to an embodiment of the present invention. Once the recording information storage medium 10 is loaded into the data reproducing apparatus (S910), the finally updated RMD is read out from the recording information storage medium 10 and stored in the memory 3 (S930).

The process of reading the finally updated RMD into the record information storage medium 10 is performed upon initialization for use of the record information storage medium 10 once. That is, the controller 2 reads out basic control information for use of the recording information storage medium 10 and finally updated TDFL, TDDS and RMD from the lead-in area and stores them in the memory 3.

The control unit 2 obtains the state of the last border, the start address, and the LRA from the RMD having the structure as shown in FIG. 4 (S950). The control unit 2 determines the location where the last updated file system is recorded from the start address of the last border and the LRA (S970). For example, in the case of the UDF file system, the anchor point has at least two logical sector numbers in the border of 256, last logical sector number-256, and last logical sector number. Therefore, the starting address of the last border and the location where the file system is recorded can be known from the LRA.

If the last border is open and no data is recorded, the last updated file system may not be recorded on the last border. In this case, from the list of closed border entries 430 of the RMD, the starting address and LRA of the last closed border since last used are found. From the start address of the last closed border and from the LRA you can see where the file system was last updated.

The control unit 2 reads and reproduces the last updated file system recorded on the record information storage medium 10 once (S990). Reproducing the file system means that the control unit 2 analyzes the read file system to recognize the type, the recording position, the directory structure, and the like of the user data recorded on the recording information storage medium 10 once.

The invention can also be embodied as computer readable code on a computer readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disks, optical data storage devices, and the like, and may also be implemented in the form of a carrier wave (for example, transmission over the Internet). It includes being. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion.
