The technical field

The present invention relates to the field of disk management and its defects, and more specifically to nooboo effective defect management for recording and/or reproducing video and/or audio data from the memory with random access digital versatile disk (DVD-RAM (DVD-RAM) in real time and method of recording data in real-time using the information of the defect management.

Description of the prior art

Recording and / or playback in real time means that a given amount of information necessarily recorded or reproduced within a specified time interval, since the input information is lost if it is not processed at the time of receipt of data, and because there is a phenomenon, such as pause image or temporary interruption of music during playback of data, such as the warning information if the data is not recorded or not reproduced at a given speed. The above problems arise due to the fact that the input information cannot be controlled in time with the playback device and recording.

In version 1.0 standard MCC-RAM is disclosed a method of managing defects, which are formed on the disk, to increase the reliability of the recorded on the data disk. Sliding replacement and linear replacement include as disclosed method of defect management stages: the first way to handle the defects detected during the initialization process, and the second method replace the module with 16 sectors) block code error correction (KIO (ECC), which includes centroblast.

Sliding replacement is used to minimize the speed reduction when recording or playback due to defects, in which the number of the logical sector that you want to assign the defective sector is assigned to the sector following the defective sector detected during the certification process, which allows to detect defects of the disk when the disk is initialized, i.e. set is recorded or reproduced by slipping sector, which formed the defect during recording or playback. In this case, the number of real physical sector is moving back in line with the sector number that is assigned when the promotion of the defective sector. This residual effect is resolved through the use of sectors that match the number of defects existing in the spare area, which is located in the end part of the corresponding field of the record.

However, moving the replacement cannot be used for defect, which is formed during use of the disk. When the defective part is ignored and skipped in numbering logical sector gap is formed, which means that moving the substitution disrupts the organization of the file system. Takamine bloc KIO, including the defective sector with a block KIO existing in the spare area.

When using the linear change no skipping non logical sector, however, the position of the sector on the disk is not continuous and real data corresponding to the defective block CROS are located in the spare area.

As described above, when recording in real time, in which it is impossible to arbitrarily perform the time delay for temporarily incoming information, for example during recording, broadcast or real images, it is essential that information was recorded in the line-replaceable region in the result of a process in which the actual sensor goes up to the spare area and the search area that you want linearly to replace, and the process in which the actual sensor comes back. Therefore, the recording speed is reduced and therefore the information in real time, not continuously recorded by use of linear replacement.

Provided that the drive is DVD-RAM in accordance with the version 1.0 standard MCC-RAM handles all of this for the management of defects to minimize the load on the main computer the e to control defects in the drive, using the command specified in the standard interface. That is, if the host computer determines that they will be managed defects, it is assumed that directly manage defects will be using the drive.

Even when the host computer does not control the defects in accordance with the need of the application program, disk, DVD-RAM in accordance with the version 1.0 standard MCC-RAM must manage the defects that were recorded in the list of primary defects (SPD (PDL) and in the list of secondary defects (SVD (SDL) in accordance with rule management defects, if there is a region, replaced by slipping or linearly replaced due to defect management performed by another drive. In this case, provided that the position of the defective sector is replaced in accordance with the slipping replacement, must have been recorded in the core, and the position of the defective block is replaced in accordance with the linear replacement, was recorded in SVD. That is, when data is written after the establishment of the fact that a particular drive is not needed to perform defect management using linear replacement, we cannot guarantee that each the ü is performed in real time using current drive DVD-RAM, problems can occur because of the field that will be used with linear replacement.

A detailed description of the preferred option exercise

The following describes preferred embodiments of the recording media that stores information of the defect management to record data in real time, the method of managing defects using same, and method of recording data in real time with reference to the accompanying drawings.

For understanding of the present invention is explained in detail below sliding replacement and linear replacement with reference to Fig.1 and 2.

In Fig.1 depicts a view explaining a method of managing defects using a sliding replacement. Physical address on the disk (Fig.1) written as P1, P2, P3, ..., PN, and for recording the real data in this physically segmented sector is necessary for the logical address. These logical addresses are addresses that allow real file system to search their own data. However, the defect is detected on the third physical sector P3 (Fig.1), the logical address is not assigned to this defective sector and the number of L3 logical sector is assigned to the next physical sector P4. Then the logical sector consistently move back using the number of bad sectors, and a spare area located at the end of the corresponding data group is used by the advanced part. In this way the sliding replacement is an effective treatment in units of sector possible using a simple slip of the defective area and the sensor does not necessarily have to move to another location after the recording and playback using a simple ignore and skip the defective part. Thus, the defective area can be avoided by reducing the time delay. In this case, the position of the defective sector is replaced with a sliding replacement is recorded in the OSD.

In Fig. 2 depicts a view explaining a method of managing defects using linear replacement. In a linear replacement for detected defects arising during use of the disk after the initialization, the defects are managed in the module block KIO, i.e. modules with 16 sectors. In other words, when in the specific sector, an error occurs and the I bug fixes module fixes errors on each data previously recorded on the disc must be changed. Thus, the handling should be carried out in the module block KIO and way of moving replace precultural defective sector and destination logical sector cannot be used as the logical address region, where data that has already been recorded, you cannot change. When a defect occurs in logic block LB3 (Fig.2), the defective area, which is recorded in the SVD will not be used and the defective part is replaced with a usable block existing in a spare area. Replaced unit (SBk in Fig. 2) in the spare area has the same logical number (LB3) block, as the erroneous block.

In the play sequence shown in Fig.2, the reading continues only to the defective block, as in region 1, the replaced block KIO, existing in a spare area, is read by moving the sensor or similar way as in region 2, and the data is continuously read from the block, which immediately follows the defective block, as in region 3. To treat defects, as described above, the movement of the transducer occurs so sposobstvuya replaced unit. Thus, for reading or writing data takes a long time, so it's a defect management is not intended to record in real time.

In Fig. 3 shows the table structure of the disk definition (SPD), the existing management defects (OAD (DMA)) of MCC-RAM. In particular, the position of the byte (PB (BP)) 3, the flag certification of disk records certified the contents of the entire disk and PB 16-39, flags certification group, write content certification about 24 groups of data.

In addition, the IB 0 and 1 are identifiers SPD and PB 4-7 are the values of the counters to update SPD/OSD representing the total number of updates and overwrite block SPD/OSD. That is, at the beginning of the initialization, the counter is set to "0" and incremented whenever SPD/OSD is updated or overwritten. All blocks SPD/OSD and SVD must have the same value of the counter after formatting. PB 8 and 9 indicates the number of groups and, for example, 24 of the group are recorded as "0018" (hexadecimal number).

In Fig.4A shows the structure of the flag certification of a disk shown in Fig. 3. When the bit b7 of the three bits b7 b6 b5, pre is animal a value of "1b", this indicates podgoreanu". When the bit b6 is set to "0b", it indicates success formatting using the full certification, and when the bit b6 takes a value of 1b indicates successful completion of the formatting using partial certification. When the bit b5 is equal to "0b", it indicates successful completion of the formatting on the entire disk, and when the bit b5 takes a value of 1b indicates successful execution format only and indicates that the flag certification of the group is effective. When the bit b1, representing the certification of the user is set to "0b", it indicates that the drive has never been certified by the user, and when the bit b1 is equal to "1b", it indicates that the drive has already been certified by the user one or more times. When bits b0, which is a certification of the manufacturer of the disk equal to "0b", it indicates that the drive has never been certified by the manufacturer, and when bit 0 is equal to "1b", it indicates that the drive has been certified by the manufacturer one or more times. Other bits b4, b3 and b2 are back. However, the bits "in process", set to "1" by using any sertifikaciis in "000".

Fig. 4B depicts the structure of each flag certification a bit 16-39 (Fig. 3). When the bit b7 among two bits b7 and b6, representing the state of data in real time, takes a value of "0b", it indicates the completion of the format of the corresponding group, and when the bit b7 is equal to "1b", it indicates that the corresponding group is formatted. When the bit b6 is equal to "0b", it indicates that the group is formatted using full certification, and when the bit b6 is equal to "1b", it indicates that the group is formatted using partial certification. When the bit b1, which is a certification of the user is set to "0b", it shows that the band has never been certified by the user, and when the bit b1 is equal to "1b", it shows that the group has been certified by the user one or more times. Other bits b5, b4, b3, b2 and b0 stay back.

In Fig. 5 depicts a table showing the contents of the list of secondary defects (SVD). PB represents the position of the corresponding byte, starting with 0. Positions 0 and 1 of the respective bytes are identifiers SVD, and conditions 2 and 3 of the respective bytes are back. Positions 4-7 the every time when updating the contents of the SVD. The position of the corresponding byte 8-15 represent the flags completely spare area, and the position of the corresponding byte 16-19 indicate the updated counter value SPD/OSD, each of which shows the total number of updates and overwrite block SPD/OSD. The counter value is set to "0" after the start initialization and is incremented by 1 whenever SPD/OSD is updated or overwritten. As mentioned above, all blocks SPD/core and SVD must have the same value of the account after the end of the formatting. Regulations 20 and 21 of the respective bytes are back, and regulations 22 and 23 of the corresponding byte indicate the number of inputs in the SVD. The remaining provisions of the relevant bytes show each input SVD.

In Fig.6 shows the structure of a flag completely spare area positions 8-15 of the respective bytes (Fig. 5). In Fig.6, if the bit representing the respective group, is set to "1", this indicates that the replacement units do not remain in the group, and if the bit is set to "0", it indicates that the spare block remains in the appropriate group.

Fig. 7 depicts the structure of the input SVD, pokazat was replaced FRM writes a binary "0", and when the defective block is not replaced or were missing spare area, FRM writes a binary "1". Enter SVD includes a first sector number of the defective block and the first sector number of the replacement unit. In this case, if the defective block is not replaced, the hexadecimal number "000000" is written in the area where the registered number of the first sector of the replacement block.

Meanwhile, when recording in real-time processing of relevant data within the specified time becomes more important than some of the error real data. In particular, in the case of an image or the like, the failure is detected on any part of the screen when in picture there is a small error. On the other hand, when the input data cannot be processed in time, constant data error occurs, which leads to impossibility to normal playback. Therefore, the data processing time is very important.

Thus, for recording in real time is proposed to use a method to avoid the use of linear replacement. When the linear replacement is not used, must be part of production and such content will be described with reference to Fig. 8A and 8B.

Fig. 8A and SB represent the structure of the flag certification of the disk and the flag certification of the LDS group, proposed in this invention for recording data in real time, respectively. The structure of the flag certification of the disk and flag certification group (Fig. 8A and 8B) are the same as in Fig. 4A and 4B, except for the bit position b2. That is, as shown in Fig. 8A, when the corresponding drive is used without linear replacement, the bit position b2 of the flag certification of the disk is set to "1", and when you are using the correct disk using linear replacement, as in the prior art, the position of the bit b2 is set to "0". In Fig. 8A and 8B, the information relating to the use or non-use of linear replacement, stored in position 2 (b2) bits, called defect management disk.

Also in the case when only a specific group of partially initialized to prevent linear replacement, as shown in Fig. 8B, the position 2(b2) bit flag certification group for the relevant group is set to "1" to show that the linear replacement is not performed in the data area in the appropriate group. In the embodiment, nastoyashzee in Fig. 8A and 8B, but you can use other reserved bits. In this case, is reserved each existing region b2 and its value is written as "0".

When the bit b2 to the control mode of the defect disk flag certification drive or flag certification group is set to "1" after disk initialization, SVD only records the address of the start sector of a block having a defect arising during use of the disk, writes bits FRM input SVD as "1" and the linear replacement is not performed. Hexadecimal number "000000" is written in the field to record the first of sector number of the replacement unit input SVD.

Thus, while maintaining compatibility between the method of managing defects, based on the current standard DVD-RAM, and the method of the present invention, there is proposed a method that allows to show the existence of nonlinear replaced by blocks, as in the existing method of managing defects, it is also a way of allowing nonlinear replace defective blocks, thereby performing recording and reproduction of data in real time.

Determining regardless of whether the replaced defective area on the block, existing is whether the non-use of defect management for linear replacement, recorded in the defect management area on the entire disk or specific area of the disk, regardless of the type of data that will be recorded in the respective field.

Also determine regardless of whether the replaced defective area on a block that exists in the spare area using the linear replacement is done by using the information related to the use or non-use of defect management for linear replacement, written in the management of defects on the entire disc or a specific area on the disk only if the required data will be recorded in real time.

Method for preventing linear replacement in relation to the entire disc or a specific disk group, was described on the basis of the above variants of implementation. In another embodiment, when the mode control defects disk is set as "1", it can be used as information indicating that the linear replacement is not performed with respect to a block having a defect in the disk for recording information, requiring the recording and playback in real time, but the linear replacement can be performed with respect to the area of the disk, does not require the time, have already been recorded in the area in which data should be written in real time, and the defective region, therefore, is replaced by the nonlinear, linear replacement of the defective areas should be able to cancel. Therefore, when the control mode defects of the disk is set as "1", this may indicate that the linear replacement defect can be canceled when recording information in real time.

To prevent all linear replacement in relation to the entire drive or to the group on the disk, information related to defect management disk is set after initialization as "1". On the other hand, when the linear replacement is not performed only in the case of recording data in real time, no need to install after initialization information on the mode of the defect management. That is, when determining that there is a need to write data to disk in real time, the control mode defects of the disk is set to "1" only before recording data in real time. At this time determining regardless of whether made whether the corresponding disk, which is suitable for recording data in real extent of what is appropriate, control mode defects of the disk is set to "1". On the other hand, the necessary process of informing the user that the disk is not suitable for recording data in real time.

Fig. 9 depicts an algorithm illustrating a method of recording data in real time without performing defect management using linear replacement in relation only to the data necessary for the further record, when the control mode defects of the disk is set to "1".

In Fig.9, first in step S101 determines whether the control mode defects disk, the value "1", which is set before writing data to disk. If the control mode defects of the disk is set to "1" at step S103 determines whether the data, which will record data in real time. If defect management is set to "0" at steps S102 and S108 all data is written on the basis of the method of the overall management of defects, which are defined in the standard book version 1.0. When at step S103 determines that the data that you want to record, are not the data in real time, move on to step S102, at which carry out the overall management of the defects. the no, move on to step S104, which determines whether there is already replaced by a linear defect in the area where you want to write data.

When at step S104 has determined that replaced the linear image defect exists in the field, then the data record is replaced by a linear image defect is canceled at step S105. When replaced by the linear image defect does not exist in the region for recording data, at step S106 determines whether there is a newly discovered flaw in the field to record data.

When at the step S106 is determined that a new defect is detected, at step S107, the information representing that the defect has not been replaced in a linear manner, write in the list of secondary defects (SVD) management defects. Then, in step S108, the data recorded in the required field. Also, when a new defect is not detected at step S106, in step S108 write data in real time in the required field.

Step S105 cancel linearly-replaced defect and step S107 records information representing that the defect has not been linearly replaced, perform using the record number of the first sector of the replacement block as hexadecimal "000000" additional information about linear-Board defects of the disk is set as "1", you can see from the comparison of this information about the mode information FRM that the value of information FRM is different from existing information FRM.

That is, information FRM based on an existing standard documentation, means that the block having the defect is caused by a specific reason, has not been replaced on the block in the spare area or the spare area cannot be replaced. On the other hand, information FRM based on the new definition is added to the value of the existing FRM and may be information representing the fact that, when the control mode defects of the disk is set to "1", linear replacement for the defective block is replaced with the existing method of linear replacement has been canceled for recording in real time or a defective block has not been replaced in a linear manner to record in real time.

As the drive mode of the defect management which is set as "1", should probably include information in real time, the disk can be used as information to prohibit redistribution of data on the disk without consideration of information in real-time. A collection of pieces from the collection of parts f the emission on the disk. Read after redistribution is a method of reading data and further replacement block of data is likely to be a defect with the unit placed in the spare area.

Fig. 10 depicts the structure of the improved input SVD to cancel the linear change proposed in the present invention. When already replaced the defect exists on the corresponding disk after recording data in real time, the method of recording information area in which the first sector number of the replacement unit, as described above, is written as a hexadecimal number "000000" and the bit is set FRM "1", depicted as a process to cancel the linear replacement.

This method can minimize the change in the existing standard. However, in this method, the information block, which is defined as defective and replaced, should be removed so that the linear replacement could randomly run, cancel and re-run without the consistent use of the spare area. In particular, when linearly-replaced block in the spare area is defective and replaced again, information associated with a linearly-replaced defective block in the spare area is lost.

In order to solve such a problem, the cancelled flag line replacement (CLR) is again determined by using a spare bit of input SVD, which is not in use. When linear substitution relative to the corresponding input MIA is cancelled for recording data in real time, you can use method flag is set CLR ("cancel") to "1". In this case, when the reset flag is set to "0", it indicates that the replacement block allocated without using using data in real-time. In the structure of the input ATS (Fig. 10), for example, an unused bit b31 is used as a flag CLR.

NGOs be divided into three cases, in which: (1) data in real time are not recorded on the entire disk, (2) two types of data, i.e. data in real-time and data in real-time, co-exist on the disk, and a method of controlling linearly-replaced defect is not used in relation only to the data in real time, and (3) only the data in real time is recorded on the entire disk, then there is a way to control linearly-replaced defect is not used in relation to all recorded data.

In particular, in the third case, the change in real time is not used to the whole disk to a spare area for defect management can be set smaller than in the first and second cases. Below is described in detail in Fig. 12 and 13.

When these three or more ways to control the defects apply to the same disk, different compliance possible according to the intended use of the disk and the disk can be more efficiently used. However, considering the condition, such as case changes and disk usage between playback devices, conditions, defect management, using appropriate discussed the use or non-use of linear replacement, described in Fig. 8 is insufficient for the management of defects in the above case.

Thus, as shown in Fig. 11, information on defect management, allowing to represent linear replacement or non-replacement depending on a variety of different control modes defects, backed byte, located in SPD management defects (OAD) on the disk. That is, in Fig. 11 shows the case of using two significant bits b7 and b6 of the relevant provisions WR byte SPD, that is his eleventh byte, for example, by selecting the control mode (UD (DM)) defects depending on the use or non-use of linear replacement.

As shown in Fig. 11, when the mode information UD is "00b", it shows that moving the replacement and linear replacement applies to all data on the disk, when the mode information UD is "01b", this shows that the linear replacement is selectively used in accordance with the type of information (in this case, the data in real time and the data is not in real time), and when the mode information UD is "10b", this shows that the linear replacement is not used in relation to kmenu are mandatory and this mode is only applicable to data other than the data in real time in the first case described above. When the mode information UD is "01b", the linear replacement is required, but a linear replacement for the data in real time is optional. This mode is a defect management for a hybrid drive, including how the data in real time and the data is not in real-time in the second case described above. When the mode information UD is "10b", is permitted only moving replacement, and this mode is defect management for only the actual data in the third case described above. When the mode information UD is "10b", the physical location of the disk can be changed.

Meanwhile, since the linear replacement cannot be used for recording data in real time, the spare area required for linear replacement is actually optional. In this case, in the present invention, only the spare area for slipping replacement is set to the last group, without allocating a spare area for linear replacement (Fig. 12). In particular, a set of spare areas in the and for moving the replacement for to handle the maximum number 7679 inputs allow for registration in the main list (the OSD (PDL)) defects. In Fig. 12 sect denotes sector, blk - block and rev - momentum.

To ensure the compatibility of the present invention with the existing management structure defects, flag, allowing to detect the case in which the spare area for slipping replacement are only for recording in real time in the case in which the spare area for linear replacement and slipping replacement is distributed according to the existing method of managing defects, represented by significant bits b7 and b6 of the relevant provisions of the BP 10 bytes in SPD and MDA (Fig.13).

As shown in Fig. 13, when two significant bits b7 and b6, representing the mode UD in position BP 10 SPD byte/MDA, is "00b", it shows that using an existing method for managing defects, and when two significant bits b7 and b6 have the form "10b", uses a method of defect management write-only real-time without linear replacement, in which only the spare area for slipping replacement is in the last group of the disk. Thus, spare obselidia efficiency thanks to the use of disk space.

As described above, when supported by the compatibility of the method of the present invention with a method of defect management, based on modern standard DVD-RAM, a linear replacement is not performed when data is recorded in real-time. Thus it is possible to record and reproduce the data in real time.

In the present invention, the information representing the number of different control modes defects depending on the type of recorded data is saved to various matches are possible in accordance with the intended use of the recording media. Thus, the recording medium can be used more efficiently.

Moreover, in the present invention, when data is recorded in real time, the spare area are to be used only for real-time scale. Thus, thanks to the use of disk space, you can increase its effectiveness.
