The recording media for storing information about the type of binding and the method of processing the damaged area with the use of this information

 

The invention relates to the field of optical recording media. The recording medium has a variety of continuous basic elements of writing. Provided by the management area of the damaged areas for a check list of damaged areas. The binding region allocated directly for one of the damaged areas in accordance with a predetermined schema binding. Also has a predetermined area for storing additional information indicating whether a pre-defined scheme of binding to the binding, which is located directly behind the mentioned one damaged area. The technical result - the possibility svyazyvaniya when lump-sum mode write data in large quantities. 3 S. and 14 C.p. f-crystals, 5 Il.

Technical field the Present invention relates to the field of optical recording media having continuous basic recording elements, in particular to the recording media for storing information about the type of binding that indicates whether the schema binding to the area located directly over the damaged area, and how to handle the damaged area, which is used axalingua disk rewritable (DVD-PZ) and digital versatile disk recordable (DVD-R) are continuous, unlike elements of the storage device with a random sample of the MCC (NVR-MCC), which are separated by areas of physical identifier (PID) or buffer zones (additional area allocated in accordance with the requirements for precision control spindle motor) requires that the starting point of the entry of each basic element in the MCC-PZ was precisely defined. Basic element recording NVR-MCC can be a sector, and the base element of the record of the MCC-PZ may be a block of code with error correction (CRO).

Because the basic elements of the MCC-H and MCC-PP, having the same physical formats, are continuously, as described above for recording, step recording, that is, the mode in which data transmission is broken, in other words, new data is written after the previous data, in the COURT-Z and COURT-PZ is binding, in which the scope of the binding is allocated a predetermined number of bytes (for example, 3 bytes) to the next point start recording. In addition, there are two size of the binding used step-by-step record: 2 KB and 32 KB.

In the case of the MCC-PP, when in list invalid on the th, in the MCC-PZ when writing the actual data to the user after registration the damaged area together with schema binding mode is limited superimposed writing, like recording, step recording. Thus, in the specification modern MCC-PZ uses only the schema binding for recording, step recording mode and limited entry overlay. Specification of the MCC-PP does not specify a particular schema binding for processing the damaged area, for example, determining the scope of the binding after the damaged area.

In Fig.1 is a diagram illustrating the scheme of Association, which takes place in normal recording, step recording, and showing the old data 4, 32-KB region of the link 2 and the new data 7. After recording, the old data 4 without filling out a basic element of the recording element unit KIO in Fig.1) are insignificant data 5 from the rest of the base element records where data is not recorded in the first sector after the label synchronization 1. Write new data 7 user begins after the data binding 6 in 32-KB region of the binding 2 for step-by-step account.

When such reference signals, as the signal caravelas errors that is, when extensive damage exists on many tracks), when passing through the damaged area of the block read/write all of these signals (the signal swing, the signal MUK and so on) are not generated. In this case, the continuous recording becomes impossible, and because the data should be written after the damaged area is similar to the recording, step recording.

In the MCC-PP data is written in recessed tracks, and the information which indicates the number of physical blocks KIO, written in the form of microglobuline in the track pads and is called the signal MUK. In addition, the swinging track with a predetermined frequency.

Therefore, it is necessary to define a new schema binding, as described above, after the damaged area is schema binding, which is defined only for normal recording, step recording, or RFM superimposed writing. Because the schema binding defined by a specification of the MCC-PP, applicable only to the recording, step recording and RFM superimposed writing, a new scheme linking will be applicable to the area directly behind povrezhdeniya, used in conventional recording, step recording and RFM superimposed writing. That is, the binding in normal mode step-by-step account and limited account with overlay appears when new data is written after stop recording, so much data, how many of them you can record at one time. This binding is not defined for mode a single entry.

However, according to the present invention, the binding appears directly after the damaged area and occurs in a situation in which you are not fully recorded data amount which can be recorded at one time.

A brief statement of the substance of the invention the present invention is the creation of the recording media for storing information about the type of binding that indicates if linking directly after the damaged area on the recording medium, where the basic elements of the entries are continuous.

Another object of the invention is the creation of the recording media on which is directly over the damaged area of the selected predetermined number of code blocks with an error correction (KIO), which act exactly the same as the area svyazivayuschego invention is to provide a method of processing the damaged area, in which user data is recorded after selecting a predetermined region linking directly over the damaged area in accordance with information about the type of binding that indicates if linking directly to the damaged area while recording.

The next task of the invention is to provide a method of processing a damaged region in which the recording of user data starts after a predetermined number of the blocks KIO following the damaged area.

In the description formulated advantages of the invention.

To solve this task, the recording medium having continuous basic recording elements includes a management area of the damaged areas, where the registered list of damaged areas, the region linking allocated directly for one of the damaged areas in accordance with a predetermined scheme linking, predefined region, which contains additional information indicating whether, if there is or if a predefined schema binding in binding directly over the damaged area.

Furthermore, the method of processing damaged areas on the recording medium having continuous basic recording elements and process the damaged area, includes the detection of damaged areas that appear during the check access rights before recording user data, and damaged areas that appear when recording user data, a check list of damaged areas in the management of damaged areas of the recording medium and storing in a predetermined area of the recording medium additional information indicating whether a pre-defined scheme of binding to the binding directly behind one of the damaged areas.

Additionally, the method of processing the damaged area before recording user data or during recording of user data on the recording media is a certain schema binding in binding directly over the damaged area, when the recording of user data in one of the basic elements of the record reveals the damaged area.

In addition, the recording and/or playback, recording data on a recording medium having continuous basic recording elements, and reads data from the recording media and processing the damaged area of the recording medium, includes a unit for playback/recording, which records data on a recording medium and reproduces data from the recording medium, and a processing unit that, upon discovering one of the most damaged areas, specifies a predefined schema binding in binding directly behind one of the damaged area during the data recording unit recording/playback.

In addition, the recording and/or playback, recording data on a recording medium having continuous basic recording elements, and reads data from the recording media and processing the damaged area of the recording medium upon detection of one of the damaged areas specifies a predefined schema binding in binding, located directly behind one of the damaged area.

Brief description of drawings the invention is further explained in the description of the preferred variant of the embodiment with reference to the accompanying drawings, in which: Fig. 1 depicts the scheme of binding that occurs in the known method step-by-step recording; Fig.2 is an example of a method of processing damaged areas according to the invention; Fig. 3 - structure of the region identification data (IVA) as an example of storing information about the type of binding according to the invention; Fig. 4 is another example of a method of processing the damaged area, according to the invention; Fig. 5 - unit-CX is the x of the embodiments of the invention
In Fig.2 presents an example of a method of processing a damaged area in accordance with the present invention. At the time of confirmation of the right of access after registration of the list of injuries in the management data recording (DUHS) allocated area link for the damaged area, and after the binding is overwritten with the new data.

In the region of DOUZ memorized the list of damaged areas detected using the recording media, and the list of damaged areas detected during the verification of access rights. According to the present invention in the region of DOUZ maintains a list of damaged areas detected before or during recording of user data. At the same time, for example, in the field of ID data (IVA) at the beginning of the sector (which can be a block KIO or sector), which are damaged or posted data, stores information about the type of binding that specifies or no binding to the damaged area when recording user data. Then after applying the binding schema to the area located directly over the damaged area is overwritten with the new data. In another example, in the base element s whether linking directly over the damaged area, and this information about the type of binding you can contact or access. Using the information on the type of binding, the recording media may recognize data binding, which allows to distinguish data link from user data.

When write data 4 users found the damaged area 3, which is registered in the list of damaged areas in the region of DOUZ, the damaged area 3 is skipped and the user data are not recorded. At this time, to the affected area 3 of the optical beam, which is emitted by the optical source, such as a laser device, is reduced in power to a level that does not affect the recording, for example, to the level lower than the power of reading. Therefore, the optical source emitting a beam with a recording power during recording of user data when it detects a corrupted region 3 reduces power, so that the beam with reduced capacity does not affect the recording. The binding region 8 directly over the damaged area 3 is populated with data link 9, and start recording the new data 7. The size of the bind 8, appearing directly over the damaged area 3 can be either 2 kilobytes or 32 kilobytes, Otto same time, because the binding according to the present invention can be detected in the detection process of the damaged areas at the time of confirmation of the right of access, data binding can be recorded in advance for any damaged area in accordance with a predetermined schema binding (2 kilobytes or 32 kilobytes). At this time (Fig.3) as information about the type of data in the IVA provides information indicating that the recorded data binding, and as information about the type of bonding in the IVA provides information about the type of binding that indicates directly over the damaged area appears linking.

As in the rest of the base element are recorded insignificant data (for example, OOh, in the field of insignificant data directly over the damaged area when the base element of the record is not filled with user data, insignificant data can be recorded in advance in the base element of the record directly over the damaged area. This area is insignificant data can be overwritten when recording real user data.

When recording user data after confirming access rights directly for the us directly for binding. Therefore, less time to write data binding, and it has the advantage when recording in real time as data is written directly to the damaged region and binding.

In Fig.3 shows an example of storing information about the type of binding according to the present invention in the field of IVA, which is allocated to each sector and is 4 bytes. Information on the identification data includes information about the sector and the sector number, and information about the sector includes the type of sector, the method of tracking, the reflection coefficient, type of binding, type, data type and number of the layer.

Information about the type of sector in bit positions b31 represents a constant linear velocity (MLS) or a constant linear velocity zone (PLSS) as follows:
0: Type PLC
1: Type zone defined format for rewritable discs.

Information about the tracking method in bit position b30 is tracking microglobuline or in-depth tracking tracks as follows:
0: Tracking microglobuline
1: Tracking of in-depth tracks, asked for rewritable discs.

Information about court:
0: If the reflection coefficient greater than 40%
1: If the reflection coefficient is less than or equal to 40%.

Information about the type of the field in bit positions b26 b27 and represents the data area, the input area, output area or staging area for the drive to read-only as follows:
00: In the field of data
01: In the input area
10: In conclusion
11: In the intermediate region drives to read-only.

Information about the type of data in bit position b25 is data to read-only or data-binding as follows;
0: Data to read-only
1: Data binding
Information about the number of layer in the bit position b24 is the number of layer in a single layer disc or a double-layer disk as follows:
0: Layer 0 double-layer single-layer discs or discs
1: Layer 1 double layer drive
According to the present invention, information about the type of binding is determined, as described below, and is described by using b28, which is a reserve bit in the information sector in the known methods:
0: Link for step-by-step account
1: Binding for the damaged area.

If the information about the type of binding presents duet binding directly over the damaged area. The binding, which appears in the recording, step recording, or RFM superimposed writing, called the binding of type 1, and link that appears directly over the damaged area is called binding type 11.

Therefore, specifying the join type in the information about the type of binding, and so on , you can distinguish normal type binding type binding according to the present invention. If the IVA sector, in which there is a binding, contains information indicating linking directly over the damaged area, then when the link appears in the sector, it is possible to show that there is a new binding at the time of recording, step recording, or RFM superimposed writing or linking appeared directly over the damaged area. In addition, information about the type of binding can be used for high-speed data processing in the drive, because if there is information about the type of binding can be directly displayed, whether it is written the record data continuously, or they are separated by the damaged areas.

Schema binding, which accompanies the damaged area in accordance with the present invention can be applied in Seaway record.

In Fig. 4 shows another example of a method of processing a damaged area in accordance with the present invention. Reference number 11 represents the user data area, where the recorded old data, the number 12 represents a bad block KIO, the number 13 represents a predetermined number of blocks KIO allocated for the damaged unit CRO and perform the same role as the region of connection and the number 14 represents the user data area, where new data is written.

According to the present invention by using the region greater than or equal to one block KIO (32 KB) allocated directly over the damaged area detected by the confirmation of the right of access, the data region with which to start writing the new data can be detected without using the binding schema. At this time, in the region of DOUZ can be registered a predetermined number of blocks KIO directly over the damaged area, and you can determine what area of new user data follows a pre-defined number of blocks KIO directly over the damaged area in accordance with a predetermined rule.

For high-speed search in ablout to be recorded reference signal, for example, a test signal, data, or record label, which has pre-defined templates, playing the role of data binding.

When writing the actual data to the user after confirmation of the right of access, after you meet the damaged area is detected whether the test signal. If the blocks KIO allocated directly over the damaged area and performs the same function as the binding detected test signal, in the field of new user data directly over the predetermined number of blocks KIO following the damaged area, to start writing the new data that has the advantage when recording in real time. Because deep track may be subject to fluctuation, the test signal may be a signal swing.

As described above, in addition to the binding, which appears when step-by-step account or a limited account with the imposition, in the present invention uses the information about the type of binding that specifies how the binding appeared directly over the damaged area. In this case, even if the recording media were extensive damage and are not formed anchor directly over the damaged area, and can be started writing new user data, which increases the reliability of the user and provides a more reliable playback.

In addition, according to the present invention in the block directly over the damaged area detected at the time of confirmation of the right of access, pre-recorded reference signal, for example, the test signal data pattern swing-depth track or record label with a test pattern and perform the function of data binding. If the damaged area is detected, such as a test signal, directly over the predetermined number of blocks KIO following the damaged area is overwritten with the new data of the user without the use of binding, which reduces the recording time data binding and gives you the advantage when recording in real time. In addition, according to the present invention, the playback device reads the recorded information.
