The technical field to which the invention relates.

The present invention relates to an optical disk write-once, and more particularly, to a device and method of placement of the backup area on an optical disc write once, such as a disk write-once Blu-ray.

The level of technology

Currently developing a new type of optical disk for high density recording capacity, such as a rewritable disc "Blu-ray disc ("BD-RE"). The advantage of the drive "BD-RE" is that it provides an option to overwrite, so that video and audio data of high quality can be recorded, erased and re-written to him many times.

Figure 1 presents a block diagram of a conventional device for recording/playback of an optical disk drive for recording data on an optical disc such as BD-RE, and playback of information. As shown in figure 1, a device for recording/playback of an optical disk includes an optical head 11 for recording/reproducing a signal on the disk 10 "BD-RE" and with it, the system 12 records video (VDR) for processing the signal from the optical head unit 11 as a reproduced signal or demodulating and converting the external data stream in a recording signal suitable for recording on the disk 10 "BD-RE", and the encoder 13 for encoding vneshnej the analog signal and the encoded signal system 12 records video (VDR).

2 shows the structure of a conventional disk drive "BD-RE". According to figure 2, on the drive "BD-RE" are the initial area "LIA", the data area and the destination area "LOA". At the beginning and end of the data area separately placed internal reserved area "ISA" and external backup area "OSA". The user data area with numbered logical sectors LSN stored in the field data between the internal backup area "ISA" and external backup area "OSA".

According to figures 1 and 2, the system 12 records video (VDR) records incoming data from an external source after encoding and convert the incoming data signal is recorded in the block cluster corresponding to the block error control (ECC)having a predetermined recording capacity. Also, the system 12 records video (VDR) detects a defective area in the data area during recording of data.

Upon detection of the defective area system 12 records video (VDR) performs the operation on the replacement recording, recording data cluster of the defective area internal reserved area "ISA". After recording the data, the location information of the defective area and the control information for reproducing the cluster data recorded in the backup area (back area), is written as a list of defects in the initial area "LIA".

On Phi is A and 3B shown, respectively, in the typical structure of a single-layer disc BD-RE DL drive "BD-RE". As shown, the drive "BD-RE" can have one recording layer (figa) or two recording layers (pigv).

According figa, the recording capacity of the internal backup area "ISA"allocated on a single layer disc BD-RE, is 2048 clusters, and the recording capacity external backup area "OSA" is N×256 (0=<N<=64) clusters with the maximum 16384 cluster. The recording capacity of the data area of layer drive "BD-RE" is 355603 cluster. The recording capacity of the user data area of layer drive "BD-RE" is defined as the difference between the capacity of the recording area and a data recording capacity of the reserve areas. For example, if the recording capacity external backup area equal to 16384 cluster (N=64), the recording capacity of the user data area is 337171 cluster. As a result, the size of the inner and the outer back areas (18432=2048+16384) is 5.5% of the size of the user data area of layer drive "BD-RE".

According figv, on a double-layer drive "BD-RE" record internal backup area ISA0" first layer "Layer 0" 2048 clusters. Recording capacity external backup area OSA0" the first layer is N×256 clusters (0=<N<=32) with a maximum of 8192 cluster (N=32). On the other hand, the recording capacity of the internal backup area "ISA1" second layer "Layer 1" is L×256 clusters (0=<L<=64) is a maximum of 16384 cluster (L=64). Recording capacity external backup area "OSA1" of the second layer is N×256 clusters (0=<N<=32) with a maximum of 8192 cluster (N=32). As a result, the total recording capacity of the reserve areas of the first and second layers is 5.1% of the total capacity of the recording of the user data areas of the first and second layers.

Disc Blu-ray write-once BD-WO" is another type of developed optical disk with a high recording density that can be recorded and played with it high-quality data. As the name suggests, data can be written to disk BD-WO" only once and on the drive "BD-WO," they can't be overwritten. However, the data is read from disk BD-WO" can be performed repeatedly. Therefore, the disc is BD-WO" is useful when the possibility of overwriting data on the recording medium is not required.

Recently addressed the issue of standardization of the size of the drive "BD-WO". But the selection of reserve areas on the disk BD-WO"how to drive "BD-RE", would create the problem of the waste of valuable space to write due to the characteristics of the drive "BD-WO". For example, on drive "BD-RE" record of reserve areas must be large enough so as to drive "BD-RE" data overwrite multiple times and, therefore, the disc can have a lot of defective areas. And, on the contrary, dis is e "BD-WO" entry can be made only once, and so the disc can be a relatively small number of defective areas. Therefore, it is not required and would be in vain to assign to disk BD-WO" the same size of the backup area, and on the drive "BD-RE".

Preferred embodiments of the present invention

Consider the detailed description of preferred embodiments of the present invention, examples of which are illustrated in the attached drawings. Where possible, the same item numbers will be used on all drawings to indicate the same or similar elements.

Next explained in detail with reference to the drawings, examples of the method of placing the backup area on the optical disk od is obratnoi records such as drive "BD-WO", in accordance with the present invention. This method can be applied in the process of manufacturing a single-layer disc write-once BD-WO" and double-layer disc write-once BD-WO". Given the characteristics of the record data on the disc is BD-WO, you can select the maximum size of the backup area that is smaller than the maximum size of the backup areas highlighted on the drive "BD-RE".

In the present invention, the recording capacity backup(s) region(s)/surrogate(s) zone on the drive "BD-WO" is maintained less than about 5% of the capacity of the recording area of the user data. In this application the size of the recording in the field (in the absence of defects) means the size of this area. As such, these two terms are used here interchangeably. Just as an example, below we will provide an implementation option of the present invention with the purpose of recording capacity backup(s) region(s) approximately 3% of the capacity of the recording of the user data area of the disc is BD-WO".

Figure 4 shows the structure of a single-layer disc BD-WO" and the way to accommodate the backup area in accordance with the first embodiment of the present invention.

According to figure 4, a single-layer disc BD-WO" includes a single recording layer dedicated to starting area "LIA", about what actu data and the destination region "LOA". The data area includes a user data area having numbered logical sectors "LSN", and the internal reserved area and/or external backup area for recording data of the defective areas (i.e. as a replacement zones). Recording capacity internal backup area "ISA" is allocated to a predetermined fixed size (for example, 2048 clusters), and the recording capacity external backup area (OSA) is a variable, for example, N×256 clusters (0=<N<=32) with a maximum of 8192 cluster (N=32). The recording capacity of the data region, a single-layer disc BD-WO" is defined in 355603 cluster. The recording capacity of the user data area obtained by subtracting the capacity of the recording of reserve areas ("ISA" and "OSA") from the tank record the field data. For example, when the recording capacity external backup area "OSA" is equal to the maximum 8192 cluster (N=32), the recording capacity of the user data area is equal 345363(=355603-(2048+8192)) cluster. As a result, the recording capacity of the internal and external backup areas (10240=2048+8192) single-layer BD-WO in accordance with this embodiment is approximately 3% capacity records (size) of the user data area (345363 cluster) single-layer disc BD-WO".

Accordingly, when the recording capacity of the internal and external backup areas highlighted layer is the claim "BD-WO", set to approximately 3% of the capacity of the recording area of the user data by changing the maximum recording capacity external backup area, backup area of the disk BD-WO" are not spent in vain and their placement is carried out effectively.

Figure 5 shows the structure of a double-layer disc BD-WO" and the way to accommodate the backup area in accordance with the first embodiment of the present invention.

According to figure 5, the double-layer disc BD-WO" includes the first recording layer "layer 0" and the second recording layer "layer 1". The first recording layer "layer 0" includes the initial area "LIA", the data area 32A and the scope of the outer zone Outer Zone 0". The data area 32A includes internal backup area ISA0", the user data area 33a and external backup area OSA0". The second recording layer "layer 1" includes the target region "LOA", the data area 32 and the scope of the outer zone Outer Zone 1". The data area 32b of the second layer includes internal reserved area "ISA1", the user data area 33b and external backup area "OSA1". The write operation of data is performed usually in the direction of the dotted arrow "A".

Internal backup area ISA0" in the first layer has a predefined fixed size, for example, 2048 clusters. Recording capacity external reserve is the second area OSA0" in the first layer is variable and is N× 256 clusters (0=<N<=16) with a maximum number of 4096 clusters (N=16). Recording capacity internal backup area "ISA1" in the second layer is variable and is L×256 clusters (0=<L<=32) with a maximum amount equal to 8192 clusters (L=32). Recording capacity external backup area "OSA1" in the second layer is variable and is N×256 clusters (0=<N<=16) with a maximum number of 4096 clusters (N=16). The total recording capacity of the first and second data regions 32A and 32b is 711206(=355603×2) cluster.

The total recording capacity of the user data in the first and second layers is calculated by subtracting the total capacity of the back areas of the total capacity of the recording data regions of the first and second layers. For example, if the recording capacity of both the first and second outer regions "OSA0 and OSA1" equal to the maximum of 4096 clusters (N=16), and the capacity of the internal backup area (ISA1) of the second layer is equal to the maximum 8192 cluster (L=32), then the total recording capacity of the user data areas of the first and second layers becomes equal 692774 cluster [=(355603×2)-(2048+4096+4096+8192)]. As a result, the total capacity of the reserve areas of the first and second layers (2048+4096+4096+8192 clusters) is about 3% of the total capacity of the recording of user data in the first and second is Leah.

Accordingly, the total recording capacity of the first and second inner and outer back areas highlighted on dual-drive "BD-WO", becomes equal to approximately 3% of the total capacity of the recording of user data when establishing the maximum capacity of the first and second external backup areas ("OSA0", "OSA1") and the maximum recording capacity of the second internal backup area "ISA1". Therefore, the backup area is not spent in vain and effectively assigned in accordance with the characteristics of the data recording disk drive "BD-WO".

In the first exemplary embodiment of the present invention, as shown in figure 4 and 5, the backup area (for example, internal backup area and outside the reserve areas) are fully utilized as a substitute areas for storing data of the defective areas in accordance with the scheme of linear substitution. For example, if the zone cluster in the user data area is determined to be defective, the data stored in the defective area of the cluster, are also stored in the backup area, functioning as a replacement area for the defective zone cluster.

Figure 6 shows the structure of a single-layer disc BD-WO" and the way of placing the backup area on a single layer disc "DD-WO in accordance with a second embodiment of the present invention. Single-layer disc BD-WO is, shown in Fig.6, includes an initial region, the data region and the destination region. The data area has a fixed size, for example, 355603 cluster.

The initial region includes first and second zone defect management "DMA1 and DMA2 and time zone management defects "TDMA". Time zone defect management is an area to temporarily record information management defects disc BD-WO and information management up until the disc is BD-WO" will not be completed. For example, during a write operation of user data area, if the data in the area of the defective cluster in the user data area is recorded in the spare part (replacement area) reserve areas according to the scheme of linear substitution, then the information (for example, information about the location, size, etc) of the area of the defective cluster and the corresponding replacement area within the reserve area is temporarily stored in the temporary management area defects, as "TDMA". Then, if the disc is BD-WO" must be finalized (e.g., upon completion of writing data in the user data area), the information "TDMA"stored in the temporary management area defects, is transferred to one or each of the control zones of defects "DMA", assigned to drive "BD-WO". In this example, time zone control is of defects, provided in the initial area has a fixed size, for example, 2048 clusters.

The data region includes internal reserved area "ISA", the user data area 34 and the external backup area "OSA". In this example, all internal reserved area "ISA" is used as an area for linear replacement (i.e. as the swap area). In other words, the area of the temporary defect management is not placed in the internal backup area "ISA". Usually internal reserved area "ISA" has a fixed size (for example, 2048 clusters), and external backup area "OSA" has a variable size.

External backup area "OSA" includes intermediate zone management defects (IDMA) and the replacement area 40 for linear replacement. In this example, the intermediate zone defect management "IDMA" dedicated bordering the replacement area 40. The size of the intermediate zone defect management "IDMA" is assigned to a variable depending on the size of the external backup area "OSA". Because the external backup area "OSA" has a variable size, the intermediate zone defect management "IDMA" also has a variable size.

Here, a distinction is made between intermediate zone defect management "IDMA" and time zone management defects "TDMA"having a fixed size in the initial region the STI, in that area "IDMA" has a variable size and may differ from zone "TDMA" depending on the usage data recorded timing. However, zone "TDMA" and "IDMA" can store the same content, despite the differences between the terms. This will be explained below.

In this example, the intermediate zone defect management "IDMA"having a variable size, allocated inside the external backup area "OSA", depending on whether allocated or not external backup area "OSA". For example, if external backup area "OSA" is selected, the zone "IDMA" stands out in it, as it was mentioned in the text above. But if external backup area "OSA" is not selected, the zone "IDMA" cannot be selected, and can only be allocated area "TDMA"having a fixed size, as it was mentioned in the text above. In another embodiment, external backup area "OSA" can be selected without selecting the area, "IDMA". However, if external backup area "OSA" is selected, it is preferable to select it zone "IDMA".

The size of the intermediate zone defect management "IDMA", located on the outer track of the disk depends on the variable size of the external backup area "OSA". In this example, the size of the external backup area "OSA" is N×256 clusters (0≤N≤64). In this case, the size of the zone "IDMA" can be R×256 clusters are the moat, where P is an integer defined as P=N/4. To have when determining the size of the zone "IDMA" can be used a method in which the size of the zone "IDMA" is defined in a quarter of the size of the external backup area "OSA". For example, if N=64, then the size of the external backup area "OSA" is defined equal to 16384 cluster (16384=64×256) and P=N/4=16. As a result, the size of the zone "IDMA" in accordance with the present invention is defined 4096 clusters (4096=h). Similarly, the size of the intermediate zone defect management "IDMA" can be variable depending on the size of the external backup area "OSA", given that the allocation of external backup area "OSA" replacement area for linear replacement, the size of the replacement area, the size of the defect management "DMA" and the size of the backup(s) region(s) independent of each other. Conversely, the size of the inner tracks of the disk (especially the size of the time zone defect management "TDMA", located in the starting area) has a fixed size.

7 shows the structure of a double-layer disc BD-WO" and the way of placing the backup area on dual-drive "BD-WO in accordance with a second embodiment of the present invention.

According to Fig.7, the double-layer disc BD-WO" includes the first layer "layer 0" and the second "layer 1". The first layer"layer 0" includes an initial region, the data region 35A and the scope of the outer zone Outer Zone 0". The second layer "layer 1" includes the target region, the data region 35b and the scope of the outer zone Outer Zone 1".

In each of the start and end fields in accordance with the present invention provides a temporary management area defects "TDMA"presented as the first 37A 37b and the second zone "TDMA", and there are several areas management defects "DMA". Several zones defect management "DMA" is also provided in each of the outer zones of the "Outer Zone 0" and "Outer Zone 1". Each time zone defect management "TDMA"provided for in the initial area and the destination area has a fixed size, for example, 2048 clusters.

The first data region 35A of the first layer "Layer 0" includes interior back area ISA0", the user data area 36A and external backup area OSA0". Internal backup area ISA0" has a fixed size (for example, 2048 clusters), and external backup area OSA0" has a variable size. Here all internal backup area ISA0" is used as a replacement area for linear replacement. External backup area OSA0" includes the replacement area 38d for linear replacement, and the first intermediate zone 38A defect management "IDMA" for storing therein information "IDMA" for defect management. That is, in the internal backup is the area ISA0" first layer "Layer 0" area for the temporary defect management is not allocated.

The second data region 35b of the second layer "Layer 1" includes interior back region "ISA1", the user data area 36b and external backup area "OSA1". Each internal and external backup area "ISA1" and "OSA1" are of variable length. Each of the inner and outer back areas "ISA1" and "OSA1" includes the replacement area 38f or 38d for linear substitution and intermediate zone 38b or 38C defect management "IDMA" for storing therein information "IDMA" for defect management. In this example, the intermediate zone 38A-38C defect management "IDMA" are assigned as each part of the region bordering the corresponding replacement area for linear replacement. The amount of the reserve areas "IDMA" is allocated depending on the size of the reserve areas "ISA1", "OSA0 and OSA1", while the backup area "ISA1", "OSA0 and OSA1" are of variable length.

In this case, the intermediate zone 38A-38C defect management "IDMA" stand out inside the reserve areas, depending on whether allocated or not, the backup area. For example, if the drive "BD-WO" dedicated backup area, it can be selected corresponding to the intermediate zone defect management "IDMA". But if the backup scope is not selected, then the corresponding intermediate zone defect management "IDMA" cannot be selected, and the can is (can be) to be allotted(s) only temporary(s) area(s) management defects "TDMA, with(s) of a fixed size. In one example, if the drive "BD-WO" was selected internal backup area ISA0", but not selection "ISA1", "OSA0 and OSA1", then there will only be allocated the first time zone 37A defect management "TDMA", a second time zone 37b "TDMA" and the intermediate zone 38A-38C defect management "IDMA" on the disc cannot be selected. In another example, if the drive "BD-WO" selected backup area ISA0 and ISA1" (not the area OSA0 and OSA1"that can be allocated time slots 37A and 37b defect management "TDMA" and the intermediate zone 38b defect management "IDMA" (but not the intermediate zone 38A and 38C "IDMA"). In another example, the intermediate zone defect management "IDMA" may not be allocated within the corresponding backup area, even if the corresponding backup area is allocated for disc BD-WO". For example, even if the backup area ISA0", "OSA0 and OSA1" allocated on disk BD-WO"corresponding to the intermediate zone 38A and 38C defect management "IDMA" can not be allocated. It should be noted that one or more spare area ISA0", "OSA0 (with intermediate zone 38A defect management "IDMA" or without it), "OSA1" (intermediate zone 38C defect management "IDMA" or not) and "ISA1" (intermediate zone 38b defect management "IDMA" or not) can be allocated on disk BD-WO" od is Oh or more temporary management area defects "TDMA".

The size of the intermediate zone defect management "IDMA" may depend on the size of the reserve areas "ISA1", "OSA0 and OSA1". For example, the size of each of the external backup area OSA0 and OSA1" is defined equal to N×256 clusters (0≤N≤32), and the size of the internal backup area "ISA1" is defined equal to L×256 clusters (0≤L≤64). Then the size of each of the intermediate zones 38A and 38C defect management "IDMA" is defined equal to P×256 clusters, and the size of the intermediate zone 38b defect management "IDMA" is defined equal to Q×256 clusters, where P and Q are integers, defined as P=N/4 and Q=L/4. There may be used a method in which the size of the intermediate zone defect management "IDMA", which has a variable size that is determined in a quarter the size of the corresponding external/internal backup area.

As an example, if N=32 (maximum), then the size of the external backup area OSA0 and OSA1" a total of 16384 cluster and P=N/4=8. Therefore, the size of the staging areas 38A and 38C defect management "IDMA" a total of 4096 clusters. And if L=64 (maximum), the size of the internal backup area "ISA1" is 16384 cluster and Q=L/4=16. As a result, the size of the intermediate zone 38b defect management "IDMA" is defined 4096 clusters. In accordance with this example, the common poppy is imally the size of the data region (35A and 35b) double-layer drive "BD-WO is 711206 clusters: the total maximum amount of the reserve areas ("ISA0", "ISA1", "OSA0 and OSA1") double-layer drive "BD-WO is 34816 clusters, the total maximum size of the intermediate zones (38A-38C) management defects "IDMA" is 8192 cluster, the total maximum size of the replacement zone (zone "ISA0" and zone 38d, 38f and 38g) within the reserve areas is 26624 cluster and the total size of the user data (36A and 36b) is 676390 clusters. Therefore, the total storage capacity (size) replacement zones ("ISA0", and zones 38d, 38f and 38g) in reserve areas double-layer drive "BD-WO" corresponds to approximately 4% of the total capacity of the recording of the user data of a double-layer disc BD-WO".

In this case, the size of the intermediate zone defect management "IDMA" may vary depending on the size of the reserve areas "ISA1", "OSA0 and OSA1" given the fact that the allocation of the replacement area for linear replacement in the corresponding backup area, the size of the replacement area, the size of the staging area (s) "IDMA" and the size of the backup area vary from one another. Conversely, the size of the inner tracks (especially time zone defect management "TDMA", located in each of the start and end fields) has a fixed size.

Arrows in each of the areas shown in Fig.6 and 7 show examples of the directions of the data record.

In accordance with storymania implementation of the present invention, as shown in Fig.6 and 7, if the detected defective area within the user data area during the operation of writing data to a disc BD-WO", the data written or copied in the defective area is recorded in the replacement area backup area in accordance with a linear substitution. Information pertaining to the defective area and the replacement area, and any other information are written to a temporary(s) and intermediate(s) zone defect management "TDMA" and "IDMA", highlighted in a special area of the disc. The same information management defects can be recorded in each of the zones defect management "TDMA" and "IDMA".
