Hereinafter, exemplary embodiments of a recording medium and a recording medium recording and reproducing method according to the present invention will be described in detail with reference to the accompanying drawings.

In addition, the term used in the present invention was selected as a general term that is widely used as possible at present, but in certain cases there is a term arbitrarily selected by the applicant, in which case the meaning is described in detail in the description of the invention, It is to be understood that the present invention is to be understood as the meaning of terms rather than names.

In this regard, in the present invention, "recording medium" means any medium in which data is recorded or data recording is possible. For example, it is meant to encompass all media regardless of the recording method such as disk or magnetic tape. Hereinafter, the present invention will be described by using a disc (disc), in particular, a "Blu-ray Disc (BD)" as a recording medium for convenience of explanation, but it is obvious that the technical concept of the present invention is equally applicable to other recording media. something to do.

In addition, in the present invention, "management area" means an area for recording management information of a recording medium. The management area may include a temporary disc management area (TDMA) and a disc management area (DMA). The temporary disk management area (TDMA) means an area for recording management information before disk closing in the disk, and the disk management area (DMA) means an area for recording final management information during disk closing. For example, the TDMA may be provided in the lead-in area and the spare area (ISA or OSA), and the DMA may be provided in the lead-in area and the lead-out area, respectively.

The TDMA and the DMA have the following relationship. Due to the characteristics of a write once Blu-ray Disc (BD-R), not only defect management information generated during use of the disc but also general management information indicating the recording state on the disc are mixed in the TDMA. For example, when a disk is closed, the disk can no longer be written to, so that the final management information in the TDMA is transferred to the DMA and recorded. Therefore, management information is recorded in the TDMA while the disk is in use, and final information in the TDMA is previously recorded in the DMA when the disk is closed, and the disk is reproduced by utilizing the management information in the DMA after the disk closing.

In addition, in the present invention, "test zone" refers to an area allocated for performing OPC in a recording medium, and "OPC (Optimum Power Control)" refers to a recordable disc. The process of calculating the optimal recording power. In other words, when a disc is loaded into a specific recording / reproducing apparatus, the recording / reproducing apparatus repeatedly performs a process of recording and reproducing at a specific recording power in the test area of the disk to calculate an optimum recording power applicable to the corresponding disk. The optimal recording power determined by the optimal recording power calculation process is then used when recording the corresponding disk. Therefore, since a test area is required for a recordable disc, the present invention will be described with reference to the OPC area and the DCZ (drive calibration zone) area as examples of the test area, but the present invention is not limited thereto.

In addition, in the present invention, an "INFO zone" means an area including information related to data exchange on a disk. In particular, in the recording medium having a plurality of recording layers, the inner region and the outer region may include at least one info region. For example, when two info areas exist in the inner area and the outer area of the zeroth recording layer L0, which is one of the plurality of recording layers, respectively, the information area existing in the inner area is defined as the first information area INFO1. The second information area INFO2 may be called, and the info area existing in the outer area may be called a third information area INFO3 and a fourth information area INFO4. In this regard, the info area may include a DMA including management information, a control data area including control information, and a physical access control (PCA) area.

Incidentally, in the present invention, "multi layer" means a plurality of recording layers. In particular, the case of having two recording layers in a multi layer is referred to as a "dual layer". Although the present invention will be described based on the recording medium having four recording layers, the present invention is applicable to all recording media having a plurality of recording layers.

1 shows an embodiment of a recording medium according to the present invention. In particular, the structure of a recordable multilayer Blu-ray disc (e.g., BD-R, BD-RE) is schematically shown.

 Although the disk of Fig. 1 shows the case of having four recording layers in the disc, it is clear that the present invention is applicable to the case of having n recording layers in the disc. In the disc according to the present invention, each recording layer is a first recording layer (Layer 0: referred to as 'L0') and a first recording layer sequentially from the recording layer furthest from the direction in which the optical beam is incident. (Layer 1: hereinafter referred to as 'L1'), Second recording layer (Layer 2: hereinafter referred to as 'L2'), Third recording layer (Layer 3: hereinafter referred to as 'L3') The recording layer (Layer n: hereinafter referred to as 'Ln'). In this embodiment, the disk shows four recording layers L0, L1, L2, and L3. Of course, the disc of the present invention may be arranged in the order in which the recording layers are close to the light beam, and the present invention is not limited to the recording layer arrangement order.

In the disc of the present invention, each recording layer L0, L1, L2, and L3 is divided into an inner zone, a data zone, and an outer zone from the inner circumference of the disc. The inner zone and the outer zone include a test zone and a management zone. The data zone includes a user data zone for recording user data and a disk defect management. An inner circumferential spare area ISA and an outer circumferential spare area OSA are provided as spare areas. However, the spare area may not be allocated as necessary.

Fig. 2 shows a first embodiment of the inner area in the recording medium according to the present invention. In particular, in order to have a structure in which a recording medium having a plurality of recording layers is resistant to scratches and foreign matters, the inner region has a structure in which the TDMA and OPC regions are not provided at physically the same position with respect to the traveling direction of the light beam. It is.

Referring to FIG. 2, the inner region of L0 is formed from the inner circumference of the disk by the first protection zone (Pion 1), PIC area, second protection zone (Protection zone 2), second information area (INFO2), OPC0 area, TDMA0, One information area INFO1 is provided. For example, referring to the size of a specific area included in the inner region of L0, the second protection region (protection zone 2) is 223 clusters, the second information region (INFO2) is 256 clusters, the OPC0 region is 2048 clusters, and TDMA0 is 2048 clusters, the first information area (INFO1) can be 256 clusters.

The inner area of L1 is the first protection zone (buffer), buffer, OPC1 area, buffer, second information area (INFO2), TDMA1, 0th reserved area (Reserved0: Rsv0) from the inner circumference of the disk. And a first information area INFO1. For example, looking at the size of a specific area included in the inner area of L1, the buffer is 1547 clusters, the OPC1 area is 1547 clusters, the buffer is 1770 clusters, and the second information area (INFO2) is 256 clusters. The TDMA1 may be 2048 clusters, the reserved area 0 (Reserved0: Rsv0) may be 2048 clusters, and the first information area INFO1 may be 256 clusters.

The inner region of L2 is the first protection zone (protection zone1), the OPC2 region, the TDMA2, the buffer, the second information region (INFO2), the first reserved region (Reserved1: Rsv1), and the first information region (INFO1) from the inner circumference of the disk. It is provided. For example, looking at the size of a specific area included in the inner area of L2, the OPC2 area is 1547 clusters, the TDMA2 is 1547 clusters, the buffer is 1770 clusters, the second information area INFO2 is 256 clusters, and the first spare area ( Reserved1: Rsv1) can be 4096 clusters, and the first information area INFO1 can be 256 clusters.

The inner region of L3 is the first protection zone (protection zone1), TDMA3, buffer, OPC3 area, second spare area (Reserved2: Rsv2), second information area (INFO2), and first spare area (Reserved1) from the inner circumference of the disk. Rsv1) and a first information area INFO1. For example, looking at the size of a specific area included in the inner area of L3, TDMA3 is 1547 clusters, buffer is 1547 clusters, OPC3 area is 1547 clusters, second information area INFO2 is 256 clusters, and the first spare area ( Reserved1: Rsv1) can be 4096 clusters, and the first information area INFO1 can be 256 clusters.

As described above, in the recording medium according to the present invention, an OPC area (for example, an OPC0 area, an OPC1 area, an OPC2 area, and an OPC3 area) provided in an inner area of a plurality of recording layers based on a traveling direction of a light beam. It is not provided at the same physical location. Also, the TDMA (for example, TDMA0, TDMA1, TDMA2, TDMA3) provided in the inner region of the plurality of recording layers is not provided at the same physical position with respect to the advancing direction of the light beam. This is to ensure that TDMA has no influence from performing OPC for optimal recording power calculation. For example, the reason why TDMA2 and TDMA3 are arranged under each of the OPC1 and OPC2 areas should be placed below the OPC area because data recorded in TDMA2 and TDMA3 may be damaged by high power during OPC performance. In addition, the TDMA is arranged so that the disks do not overlap layer by layer in order to have a structure that is resistant to scratches and foreign substances on the surface. In relation to the above, since the size of each region described above is one embodiment, it is apparent that various embodiments of the size of each region may be possible by changing, inserting, or removing a size of a buffer or a spare region.

3 shows a second embodiment of the inner area in the recording medium according to the present invention.

3 shows that the inner region does not include the TDMA and the OPC region at the same physical position with respect to the traveling direction of the light beam in order to have a structure in which a recording medium having a plurality of recording layers is resistant to scratches and foreign substances, compared to FIG. The part with the structure which does not is the same. However, the first information area INFO1 and the second information area INFO2 of L0 are provided at physically the same position as the first information area INFO1 and the second information area INFO2 of L1, and the first information area of INFO2 of L2. The info area INFO1 and the second information area INFO2 are provided at physically the same position as the first information area INFO1 and the second information area INFO2 of L3. However, the first information area INFO1 and the second information area INFO2 of L0 and L1 are not provided at physically the same position as the first information area INFO1 and the second information area INFO2 of L2 and L3. Is the difference. Note that for the structure of the inner region mentioned above, the size of each region may be different from the example of FIG.

Referring to FIG. 3, since the inner regions of LO and L1 have been described with reference to FIG. 2, the inner region structures of L2 and L3 will be described here. The inner area of L2 is the first protection zone (protection zone1), buffer (3), second information area (INFO2), OPC2 area, TDMA2, buffer, first information area (INFO1), and first spare area from the inner circumference of the disc. (Reserved1: Rsv1). The inner region of L3 is defined as the first protection zone (protection zone1), buffer, second information area (INFO2), TDMA3, buffer, OPC3 area, second reserved area (Reserved2: Rsv2), first information area (i. INFO1) and a first reserved area (Reserved1: Rsv1).

For example, referring to the size of a specific area included in each recording layer of the disk of FIG. 3, the OPC0 area, the TDMA0, the TDMA1, and the 0th reserved area (Reserved0: Rsv0) may be 2048 clusters. The size of the buffer 3 provided in the inner region of L2 is X cluster, and the size of the second reserved region (Reserved2: Rsv2) provided in the inner region of L3 is 223 cluster, OPC1 region, OPC2 region, OPC3 region, TDMA2, The size of TDMA3 can be Y cluster. Here, Y can be obtained from Equation 1 below, where X can be a value in which Y becomes an integer.

Y = (4864-223-X) / 3

In this manner, the second information area INFO2 of L0 and L1 and the first information area INFO1 of L2 and L3 are physically disposed at the same position, thereby reducing the possibility of data loss due to scratching or the like. It is preferable to design a disk structure according to the present invention in terms of data stability in the case of a multi-layer (for example, four-layer) disk.

In another embodiment of the present invention, each of the first information areas INFO1 provided in the plurality of recording layers is not provided at the same physical position at the same position relative to the traveling direction of the light beam. Note that it is also possible to arrange the respective regions so that they are not provided at the same physical position with respect to the traveling direction of the light beam.

4A to 6B will be described below by taking an example of the structure of the outer area in the recording medium according to the present invention. In particular, although the description will be made based on the recording medium having four recording layers, it is obvious that the present invention is applicable to the recording medium having a plurality of recording layers.

4A and 4B show the first and second embodiments of the outer area in the recording medium according to the present invention.

Referring to FIG. 4A, in order to have a structure in which a recording medium having a plurality of recording layers is resistant to scratches and foreign matter, the outer regions of L0 and L1 may include a third information area INFO3 and a fourth information area INFO4 as light beams. It is provided at the same physical location with respect to the traveling direction. The outer regions of L2 and L3 include the third information area INFO3 and the fourth information area INFO4 at physically the same position with respect to the traveling direction of the light beam. However, the third information area INFO3 and the fourth information area INFO4 of L0 and L1 are not provided at the same physical location as the third information area INFO3 and the fourth information area INFO4 of L2 and L3. .

In detail, the outer region of L0 includes a third information area INFO3, an Angular buffer, a fourth information area INFO4, a DCZ0 area, and a protection zone from the inner circumference of the disc. The outer region of L1 includes a third information area INFO3, an angular buffer, a fourth information area INFO4, a DCZ1 area, and a protection zone from the inner circumference of the disc. The outer region of L2 includes a DCZ2 region, a third information region INFO3, an angular buffer, a fourth information region INFO4, and a protection zone from the inner circumference of the disk. The outer area of L3 includes a DCZ3 area, a third information area INFO3, an Angular buffer, a fourth information area INFO4, and a protection zone from the inner circumference of the disc.

For example, the outer region may have a size of 780 clusters excluding the protective region. Looking at the size of the specific area provided in the outer area, 96 clusters in the third information area (INFO3) and the fourth information area (INFO4), 76 clusters in the Angular buffer (DCZ0 area, DCZ1 area, DCZ2) Each of the zones and DCZ3 zones is capable of 512 clusters. Therefore, the third information area INFO3 and the fourth information area INFO4 of L0 and L1 are not present at the same physical location as the third information area INFO3 and the fourth information area INFO4 of L2 and L3. .

FIG. 4B has a reserved area in the inner circumference of the disc in the outer areas of L2 and L3, compared with FIG. 4A. At this time, the size of the DCZ2 area and the DCZ3 area is reduced as much as the spare area. For example, the size of the reserved area is 268 clusters, and the size of the DCZ2 area and the DCZ3 area is 244 clusters, respectively. In the embodiment of FIG. 4B, when OPC is performed in the DCZ2 area and the DCZ3 area, data recorded in the info areas INFO3 and INFO4 of L0 and L1 may be prevented from being damaged.

Hereinafter, in the third and fourth embodiments described with reference to FIGS. 5A to 6, the “X area” includes all of the third information area INFO3, the Angular buffer, and the fourth information area INFO4. It means an area.

5A and 5B show a third embodiment of the outer area in the recording medium according to the present invention.

Referring to FIG. 5A, the recording medium having a plurality of recording layers is provided with an X area so that only a part of the X area overlaps between adjacent recording layers in the plurality of recording layers in order to have a structure resistant to scratches and foreign matter. The recording medium according to the present invention constitutes an outer area so that a part of the X area overlaps between adjacent recording layers, but areas containing important data in the third information area INFO3 and the fourth information area INFO4 do not overlap by recording layer. It is to avoid.

Referring to FIG. 5B, for example, the third information area INFO3 and the fourth information area INFO4 include a buffer, a DMA, and a control data area (CONTROL DATA). The overlapping portions of the N layer and the N + 1 layer are a portion of the N-type Anger buffer, a fourth information area INFO4 and a third information area INFO3 of the N + 1 layer, and a portion of the Angler buffer. At this time, the DMA, which is an area containing important data in the N layer, and the control data area (CONTROL DATA) are provided at the same position with respect to the part of the angler buffer of the N + 1 layer and the traveling direction of the light beam. In addition, DMA, which is an area containing important data in the N + 1 layer, and the control data area (CONTROL DATA) are the same with respect to a part of the angler buffer of the N layer, the buffer of the fourth information area INFO4, and the direction of the light beam. In place. Therefore, even if a scratch or the like occurs on the surface of the recording medium specific position, the amount of data lost in the recording medium having a plurality of recording layers is small, and thus a recording medium having a strong characteristic such as scratching is possible.

6A and 6B show a fourth embodiment of the outer area in the recording medium according to the present invention.

Referring to FIG. 6A, a recording medium having a plurality of recording layers according to the present invention physically has an X region between adjacent recording layers in a plurality of recording layers with respect to a traveling direction of a light beam in order to have a structure resistant to scratches and foreign substances. It is not provided at the same position.

Referring to FIG. 6B, for example, assume that the total cluster size of the X region and the DCZ region in the outer region is 780 clusters. In this case, the third information area INFO3 includes a 16 cluster buffer, a 32 cluster DMA, and a 32 cluster control data area, and the angle buffer has a size of 35 clusters, and the fourth information area. (INFO4) includes 32 clusters of DMA, 32 clusters of control data area (CONTROL DATA), and 16 clusters of buffers. Therefore, the size of the X area becomes 195 cluster so that the X areas of the four recording layers L0, L1, L2, and L3 are not physically located at the same position. The size of each region mentioned in FIG. 6B is one example, and the size of each region may be changed.
