The technical field to which the invention relates.

The present invention relates to a medium for storing information, a device for use in information storage and method of recording and/or reproduction of information through this medium for storing information, and more specifically, to a medium for information storage, which stores information about the optimal model record, or information indicating whether the storage medium information is compatible with the drive corresponding to an older version of standards, to a device and method for recording and/or reproduction of information through the medium for information storage, which stores information about the optimal model record, or information about whether the environment to store information compatible with the drive corresponding to an older version of standards.

The level of technology

Conventional medium for storing information are widely used as media for recording information from the optical sensors for recording/reproduction of information in a non-contact manner. Optical discs, which are an example of media for storage of information classified as compact disks (CD) or digital versatile disks (DVD), in accordance with their capacity to store information. Examples of recordable optical discs include 650 MB CD-R (onocr is but a recordable CD-ROM) CD-RW (rewritable CD), 4.7 GB DVD/RW (rewritable DVD), DVD-RAM (DVD memory random access) and the like. In addition, developed HD-DVD having a recording capacity of 20 GB or higher.

With increasing capacity of the optical disc recording speed recording is also progressing. However, the model recording optical disc is changed as increasing the speed of their record.

Figa represents the model of the recording pulse, which is widely used in CD-RW, DVD-RAM/R/RW and the like. The model of the recording pulse shown in Figa includes multiple pulses for forming each label on an optical disc. Multipulse model is widely used to prevent distortion of the label on an optical disc due to the accumulation of heat during the formation of the label.

However, due to the fact that the energy supplied per unit time, decreases the recording speed of the optical disk, can generate an error when the data is written according to the multipulse model.

However, the decrease in energy per unit of time can be compensated by using a single pulse for each label, as shown in Figv, or by increasing the power offset (DC component power).

As described above, the environment for the storage is of information have different model records that is, the write strategy, in accordance with their write speeds. Figure 2 represents the structure of a data region, the traditional medium for storing information. As shown in figure 2, the traditional medium for storing information includes a region 100 of the input area 110 of user data and a region 120 of the output. Model information data recording is recorded in the area 100-2 control disk data region 100 of the input.

Area 100 input includes a first buffer zone 100-1, zone 100-2 control data disk, in which is recorded information relating to the management of disk area 100-3 disk test zone 100-4 test drive area 100-5 management defects, backup area 100-6 and the second buffer zone 100-7. Area 100-2 control data ROM stores the following information: disk type, version number, disk, disk size information of the recording layer(s) and similar data. Area 100-2 control data disk also stores information about the model of the data record.

For example, the area 100-2 control data disk can store information regarding the types of model entries, from the first to the third. The first type of model accounts can be the first multipulse model, the second model type record may be the second multipulse model, and the third type of model can be monopulse model (a model with a single pulse is Ohm). On Figa and 1B Ttop, Tmp, and Tcl is the model parameters account, namely the duration of the initial pulse, the duration of the set pulse and the pulse duration of cooling, respectively. Pw, Pe and Pb denote the recording power, the erase power and a power offset, respectively. T means the minimum length of the record label. 3T and 7T mean length of mark or space.

For example, the bytes from the fifth to ninth zone 100-2 control data disk to store the first write speed, the first power play, Ttop1, Tmp1 and Tcl1, respectively, as the information about the first type of model entries. The tenth byte area 100-2 control data disk is reserved. Bytes from the eleventh through the fifteenth zone 100-2 control data disk to store the second recording speed, the second power play, Ttop2, Tmp2 and Tcl2, respectively, as information about the second type of model entries. Sixteenth byte area 100-2 control data disk is reserved. Bytes from the seventeenth to the twenty-first zone 100-2 control data ROM stores a third rate, third power play, Ttop3, Tmp3 and Tcl3, respectively, as information about the third type of model entries. Twenty-second byte area 100-2 control data disk reserved.

As described above, the conventional medium for storing information classified information about models by recording the line is the result type of model records and stores this information. If you have recorded multiple models account when the drive writes the data in the medium for storing information, it reads the information about all the models account, selects a data model suitable for the drive, and writes the data respectively selected model record. In other words, after the medium for storing information, shown in figure 2, is loaded into the drive, the drive must test all types of model entries, from the first to the third, to find the optimal model record. Therefore, the drive must be designed to include functionality testing models of entry, thereby complicating the design of the drive and increasing the duration of the data record.

In a traditional environment to store information, shown in figure 2, information about its recording speed is recorded in the area 100-2 control data disk. Version information storage medium for information that prescribes the standard for the write speed is also recorded in the area 100-2 control data disk. When such a disc is loaded in the disk drive for recording/playback of data on the disk/disc, the drive first reads the version information of the downloaded ROM. If the version of the loaded disk is identical to the version of the drive, the drive records/reproduces data on/from zagrujenno the disk.

However, when developing a new version of the runtime to store information, the drive corresponding to the new version, should also be developed. The drive that corresponds to an older version of standards cannot record/reproduce data on/from the environment to store information corresponding to the new version of the standards. In other words, when the storage medium information is loaded into the drive, the drive reads the version information stored in the medium for storing information, and can record/reproduce data on/from a storage medium for information only if their versions are the same. On the other hand, if the version of the loaded storage medium for information is different from the version of the drive, loaded with medium to store information, the drive may not recognize the loaded storage medium, because the medium for information storage stores information about a version other than the version information of the drive.

Thus, regardless of compatible drive with the medium for storing information corresponding to a different version of the standards, the drive automatically recognizes that it is not possible to record/reproduce data on/from the environment to store information corresponding to a different version of the standards.

As described above, if the medium for storing information, soo is concerned, the new version of the standards, does not contain any information about the drive corresponding to the old version of the standards, the environment for storing information of the new version can not be used in the drive corresponding to an older version of the standards, even if they are really compatible with each other. Therefore, users are uncomfortable and bear the extra costs that they must use the new drives whenever used medium for storing information of a newer version.

The IMPLEMENTATION of the INVENTION

Now will be given detailed references to embodiments of the present invention, examples of which are illustrated in the attached drawings, with the same numbers of reference denoted by the same elements throughout the text. Options for implementation are described below in order to explain the present invention by reference to the drawings.

Figure 3 represents the structure of the data area of the medium for storing information according to the first variant implementation of the present invention. As shown in Figure 3, the medium for storing information according to the first variant implementation of the present invention includes a region 10 input about the art 20 user data, which stores user data, and the region 30 of the output.

Region 10 entry includes an area of 10-2 control data ROM that stores related to the disk information area 10-3 test drive, which stores information that is used to test drive the area 10-4 test drive, which stores information that is used to test drive the area 10-5 management defects, which stores information used to correct the defect occurred on the disk, and the backup area 10-6. Region 10 input further includes first and second buffer zones 10-1 and 10-7, respectively. For example, the first buffer zone 10-1 and area 10-2 control data disk included in the scope intended only for playback for playback only, because the data is written in the form of depressions (dark spot representing a binary zero) during manufacture of the disk. Area 10-3 disk test zone 10-4 test drive area 10-5 management defects, backup area 10-6 and the second buffer zone 10-7 included in the recordable area.

Area 10-2 control data disk stores information such as the disc type, version number, size, and information about models by records and similar information. Information about the first type of model entries recorded in bytes of the item is also on the ninth zone 10-2 control data disk. Information about the second type of model entries recorded in bytes, from the eleventh through the fifteenth zone 10-2 control data disk. Information about the third type of model entries recorded in bytes from the seventeenth to the twenty-first zone 10-2 control data disk. Information about models by recording includes recording speed, power play, the duration of the initial pulse Ttop model records the duration of the set pulse Tmp model recording, the pulse width of the cooling model record, the recording power Pw, erase power Pe power offset Pb and the like.

As shown in Figure 3, the medium for storing information according to the first variant implementation of the present invention stores information about the optimal model of entry in the region 10 of the input. More specifically, information about the optimal model entries recorded in the area intended only for playback, or in the recorded region 10 of the input.

If the information about the optimal model entries recorded in the area intended only for playback, it is written in the zone 10-2 control disk data region 10 input. When considering plants for disk information about the optimal model record is written in the form of depressions during manufacture of the disk. Information about the optimal model entries recorded in special is th byte zone 10-2 control data disk, for example, in the third byte. More specifically, information about the optimal model entries recorded in bits with a zero on the seventh of the third byte.

For example, if the best model is the first model type records, 00000000b is recorded as the optimal model record. If the optimal model is the second model type records, 00000001b is recorded as the optimal model record. If the optimal model is the third model type records, 00000010b is recorded as the optimal model record.

If the data corresponding to the first type of model entries are recorded as the optimal model recording, the drive reads the data corresponding to the information about the first type of model entries. In other words, the drive reads the data corresponding to the bytes from the fifth to ninth, which contains the information about the first type of model entries, sets the mode corresponding to the read data, and writes the data according to the set mode.

Figure 4 represents another structure of the data area of the medium for storing information according to the first variant implementation of the present invention. As shown in figure 4, information about the optimal model entries recorded in the rewritable area 10 input. More specifically, information about the optimal model Zap the si is recorded in the backup area 10-6 rewritable area. In this case, after manufacture of the disk data model, the optimal custom ROM installed via disk test, and the optimal model record is written to the backup area 10-6. Information about optimal model of recording is recorded in a special byte reserve areas 10-6. For example, if the best model is the first model type records, 00000000b is recorded as the optimal model record. If the optimal model is the second model type records, 00000001b is recorded as the optimal model record. If the optimal model is the third model type records, 00000010b is recorded as the optimal model record.

If the data corresponding to the second type of model entries are recorded as the optimal model entries in the backup area 10-6, the drive reads the data corresponding to the information about the second type of model entries recorded in zone 10-2 control data disk. In other words, as shown in Figure 3, the drive reads the data corresponding to the bytes between the tenth and fourteenth, in which recorded information about the second type of model entries, sets the mode corresponding to the read data, and writes the data according to the set mode. The information recorded in the zone 10-2 control disk data shown nafig, is the same as that shown in Figure 3, except that the information about the optimal model record is written to the backup area, and thus not shown in Figure 4.

Information about the optimal model entries recorded in region 10 input and 30 output. Therefore, when there is a defect in the information recorded in one of the areas: area 10 input or region 30 of the output, it uses the information stored in the other non-defective region.

Although the above has been described a case where recorded information only about the optimal model records information about the optimal model entries recorded together with information about the multiple speed drive. For example, as information about the optimal model records and information about many of the speed of the disk is recorded in a special byte zone 10-2 control data disk, as shown in Figure 3, or in bytes of the backup zone 10-6, as shown in Figure 4.

Examples of data representing information about the optimal model records and information of the plurality of speeds of the drive are shown in Table 1.

Table 1
DataInformation
00000000 bA set of n speeds, the first model
10000000 b Many of the m speeds, the first model
00000001 bA set of n speeds, the second model accounts
10000000 bMany of the m speeds, the second model accounts

If information about an optimal model of entry with information about the many speeds is recorded in the medium for storing information, as shown in Table 1, the optimal data model and the speed of the recording medium for storing information determined at the same time. Thus, the drive writes the data in the storage medium information with improved efficiency.

If the information about the optimal model record was recorded in the area intended only for playback, it plays as the total signal or a differential signal. If the information about the optimal model record was recorded in the recorded area, it is reproduced as the total signal.

The structure of the data area of the medium for storing information according to the second variant of implementation of the present invention shown in figure 5. As shown in Figure 5, the medium for storing information according to the second variant of implementation includes the region 10 input region 20 user data and the region 30 of the output, as in the first embodiment, the present image is to be placed. However, the medium for storing information according to the second variant of implementation of the present invention stores information about whether it can work in the drive, the appropriate version of the standards is older than the version of the standards, which meets Wednesday to store information.

In General, the environment for storing information corresponding to the same standards, have the same recording modes. Each time the standard media for storing information changes, the version is also changing. In General, because the recording mode is changed to the newer medium for storing information, a newer medium for storing information is not in the drive, working on the old version of the standards. Also the medium for storing information corresponding to the old version of the standards, as a rule, does not work in the drive corresponding to the newer version of the standards. However, there are exceptional cases when the medium for storing information corresponding to a newer version of the standards, can work in the drive corresponding to the old version of the standards.

For example, the environment information storage running on 3 speeds, can always work in the drive running at 3 speeds. However, it is also possible that the 4-velocity environment for data storage will work in 3-speed drive is, and 2 - or 3-speed environment to store information will work a 5-speed drive.

If the medium for storing information, working on the set of n speeds (5≤n≤8), can operate in 2 - or 3-speed drive version of the standards, definitely not changed. However, if the environment to store information cannot work in the drive with a set of n speeds, even when the environment information storage works on the low-speed version of the standards should be changed. In other words, if the environment information storage may not work in old versions of the drive, even when it operates at its lowest speed, the version of the standards should be changed.

However, when developing a new version of the standards, the environment for storing information corresponding to the new version of the standards, can work in the drive corresponding to the old version of the standards. In this case, if the medium for storing information corresponding to the new version of the standards, does not store information about the drive corresponding to the old version of the standards, it will not write the data, despite the fact that the medium for storing information corresponding to the new version of the standards, can work in the drive corresponding to the old version of the standards. Thus, the medium for storing information and, the corresponding new version of the standards, stores information about whether it can work in the drive corresponding to the old version of the standards.

Information about being able or not the medium for storing information, shown in Figure 5, to work in the drive corresponding to the old version of the standards is recorded in the area intended only for playback, or in a rewritable area, at least one of the regions: region 10 and input region 30 of the output medium for storing information, shown in figure 5. More specifically, this information is recorded in the special bits of the byte area reserved only for playback, or recorded area. Since the structure of the data field 10 input and area 30 output similar to each other, only 10 will now be described. This description applies to the area 30 of the output.

As shown in Figure 5, the area 10-2 control data ROM that stores for disk-related information is included in the scope intended only for playback, region 10 input. Recordable area includes the area 10-3 disk test zone, 10-4 test drive zone 10-5 management defects, and the backup 10-6. 6 represents another structure of the data area of the medium for storing information according to the second variant domestic the present invention. For example, as shown in Fig.6, the backup area 10-6 stores information about being able or not the medium for storing information to work in the drive corresponding to the old version of the standards. If the information about being able or not the medium for storing information to work in the drive corresponding to the old version of the standards was recorded in the form of depressions in the area intended only for playback, it can be reproduced as a sum signal or the difference signal. If the information about being able or not the medium for storing information to work in the drive corresponding to the old version of the standards was recorded in the recorded area, it can be reproduced as the total signal.

Also information about being able or not the medium for storing information to work in the drive corresponding to the old version of the standards, written as in region 10 input and 30 output so that when there is a defect in the information recorded in one of the areas: area 10 input or region 30 of the output, it uses information that is stored in a different, not defective area.

As described above, if the environment for storing information corresponding to the version n standards, stores information about whether it is compatible with the drive, the appropriate version of the standards, bol is e old what version of n (for example, version x standards), then the drive is reading this information in order to choose the appropriate medium for information storage.

When the compatibility information is recorded in the storage medium information version n, the information about the optimal model records are also recorded. Information about the optimal model can be written in the same byte, or bytes, other than him, and bytes, which provides information about compatibility. When information about an optimal model of entry and the compatibility information is recorded in the same byte, they can be written as follows.

Two types of information are recorded in the form of combinations of bits in a special byte area reserved only for playback, or in the recorded region 10 of the input. For example, if you record 00000000b, version n of the medium for information storage is not compatible with the drive, the appropriate version of x standards. If it is written 00000001b, version n of the medium for storing information compatible with the drive that matches the version x of the standards, and the optimal model is the first model type record. If it is written 00000010b, version n of the medium for storing information compatible with the drive that matches the version x of the standards, and the optimal model record is second to t the model record. If it is written 00000011b, version n of the medium for storing information compatible with the drive that matches the version x of the standards, and the optimal model is the third model type record.

Information about how efficiently data is recorded by using a model record, especially when using multi-pulse strategy, recording is recorded. Multipulse strategy record is not used, when the speed of the recording medium for storage of information is much greater than the speed of the drive. In other words, as the speed of the recording medium for storing information becomes much greater than the speed of the drive, the data will probably be stored in the medium for storing information, using monopulse strategy account, instead of using multipulse strategy account. Thus, if you are developing a new version of the environment for information storage by increasing the recording speed, it provides information about whether the data to be efficiently recorded in the medium for storing information through the use of multipulse strategy record.

Information about whether or not the data is written using multipulse strategy of entry is recorded in the recordable region or area intended only for playback, ENISA least one of the areas: area 10 input and the region 30 of the output. The structure of the data rewritable area and the area intended only for playing, have already been described above. For example, 00000000b corresponds to the fact that data cannot be written using multipulse strategy records, 00000001b corresponds to the fact that data can be written, using multipulse strategy account. Alternatively, 00000000b corresponds to the fact that data can be written, using multi-pulse strategy, recording, and 00000001b corresponds to the fact that data can be written, using monopulse strategy record.

Information about whether or not the data is written using multi-pulse strategy, recording can be recorded separately or together with information on whether the storage medium information is compatible with the drive corresponding to the old version of the standards.

If the information about whether the environment information storage compatible with the drive corresponding to the old version of the standards, and information about whether or not the data is written using multipulse strategy entries were recorded in the area intended only for playback, region 10 input, they are reproducible as the total signal or a differential signal. If these two types of the information recorded in the recorded area, they can reproduce both the total signal.

The above description about the environment to store information according to the described variants of implementation of the present invention is also applicable to multi-layered media for information storage having two or more recording layers.

7 is a block diagram of the recorder and/or playback according to a variant implementation of the present invention. As shown in Fig.7, the recording and/or playback includes block 1001 read/write, the controller 1002, and a storage device 1003. Unit 1001 of the read/write head writes data on the disk 1000, which is a variation of the implementation environment 1000 for storing information of the present invention, and reads the data from disk 1000. The controller 1002 writes and plays for disk-related data according to the present invention, as set forth above in connection with Figure 3-6.

Though this is not required in all aspects, it is clear that the controller 1002 may be a computer executing the method using a computer program encoded on a computer-readable medium. The computer may be implemented as a chip having a built-in program, or may be a computer for General purpose or special purpose computer programmed to implement the method. In addition to t the th, it is clear that to achieve a recording capacity of several tens of gigabytes block 1001 read/write could include block type vyskocilova aperture with low wavelength used to record tens of gigabytes of data on the disk 1000. Examples of such units include units that use optical wavelengths of 405 nm and having a numerical aperture of 0.85, but are not limited to, these units are compatible with Blu-ray and/or these units are compatible with advanced optical discs (WAD - AOD).

In addition, the medium for storing information in accordance with the described variants of implementation of the present invention stores information about whether it is compatible with the drive corresponding to the old version of the standards, so that the drive corresponding to the old version of the standards can be used even when the medium for storing information corresponds to the new version of the standards.
