This application claims the priority of Korean patent application No. 2004-43332, filed June 12, 2004 in the intellectual property office of the Republic of Korea, the disclosure of which is included in the materials of the present application by reference.

1. The technical field to which the invention relates.

The present invention relates to a recorder and/or playback method of recording and/or playback to the information storage medium.

2. Description of the prior art,

In the General case, the optical disk is widely used as an information storage device in the device with an optical head for recording and/or reproduction of information. In accordance with the capacity of the recorded information of the optical disk are classified on the compact disc (CD) and digital versatile disk (DVD). Optical disks, configured to write, delete and playback the data include 650 MB CD standard CD-R, CD-RW with a capacity of 650 MB and drives standard DVD+RW with a capacity of 4.7 GB, optical discs for playback data include CD 650 MB and drives standard DVD-ROM 4.7 GB. In addition, HD-DVD, high density)having a recording capacity greater than 25 GB, are in development.

Due to the latest developments in technology the AI of the optical disk, semiconductor technologies and strategies for recording/playback, add new features and layers of recording on an optical disk and increase the recording speed must be constantly updated standards for optical systems, including optical drives and optical drives.

Figure 1 is an exemplary diagram that explains the compatibility of discs according to known techniques.

Assuming that the known standard called 'old' standard, and the standard which is updated by increasing the number of recording layers, increasing the speed of recording or adding strategy write to the old standard, referred to as the 'new' standard disk 110 old standard is intended to work in the drive 111 of the old standard and the disk 120 of the new standard is designed to work in the drive 121 new standard.

Due to the added characteristics, i.e. the number of recording layers, the recording speed or strategy records, the old standard and the new standard may not be compatible for recording and/or playback data. Compatible recording and/or playback of these two standards implies that the disk 110 old standard used in the drive 111 old standard, can also be used in the drive 121 new standard for recording and/or playback data. In addition, this implies that the disk 120 new standard is and, used drive 121 new standard, can also be used in the drive 111 old standard for recording and/or playback of data.

To ensure the mutual compatibility of the recording and/or playback between the two standards, when the disk 120 of the new standard, which applies the new functions are loaded into the disk drive 111 of the old standard, the drive 111 of the old standard is to ensure the proper handling for the new function. To do this, when you create the old standard, must be prepared by suitable treatment for future additions of new features.

In addition, the respective processing should be a generic process that can be applied to the new standard, because it must be able to apply even when the new standard is updated by adding new features.

Accordingly, for a number of different standards that they are mutually compatible for recording and/or playback preparation for adding new features should be executed when the standard create. To do this, you must create a rule by which the drive operates in known existing standard, and the General rule by which the existing drive will work in a future standard, which is not Izv the walls of an existing standard.

Thus, if the characteristic of the disk write to disk in the form of information that can normally decide for discs of different standards, even when the future drive, which added a new feature, load your existing standard, according to the information recognized information on the disk is read so that the disk can be used.

Accordingly, in order to guarantee the flexibility and scalability of the structure of the disc information, when such variables as the strategy entries are added in addition to increasing the number of recording layers and recording speed, it is necessary to structure the information about the disk and the recording method for a structure of information on the disk.

In addition, when multiple structures that drive information exists on the same carrier, there is a need to quickly find the structure of the disc information corresponding to the characteristic of the recording, from a variety of information structures on disk.

DETAILED DESCRIPTION of embodiments

Next will be made detailed reference to the existing variants of implementation of the present invention, examples of which are illustrated in the accompanying drawings in which the same designations refer to the same elements throughout the document. Options for implementation are described below relative to the figures for explaining the present invention.

Referring to figure 2, the lead-in area is located on the innermost circumference of the disk, the outlet region is located on the outermost circumference of the disk, and the region information of the user on which the record information user is located between the input area and output area.

Leadin formed pre-recorded area in which the pre-recording predetermined information in the manufacture of the disk and a recordable area.

The recordable region comprises a buffer between the pre-recorded thereof, and a recordable area, area of defect management for records relating to the defect information, such as address data replacement, which replaces the defective data appearing in the field of user information, test area, designed to test to obtain the optical recording power when data is written in the field of user information and the area information about the state of the drive/disk for recording information related to the status of the drive.

Pre-recorded area is the area management information in which recording management information, and it includes information about the type of disk, version, disk size, disk structure, disk speed, and the recording options.

In this area of control information may be written to the structure of the disc information according to the present invention. The structure of the disc information according to the present invention will now be explained relative to Fig 3.

Figure 3 is a structure diagram of the data structure of the disc information according to a variant implementation of the present invention.

In the embodiment of the present invention, the structure 300 of information on the disk is divided into table 310 General information table 320 information parameter definitions and table 330 parameters, as shown in figure 3, so that after the disc has been inserted, for disk-related information could be read more efficiently.

Table 310 General information includes the type data carrier 311, the number of layers 312 storing information and the supported speed of 313 record.

Type 311 media data indicates information about whether the media the media is write-once, rewritable media or intended for playback by the media. The number of layers 312 storing information indicates the total number of layers of information storage, which has a carrier. Supported speed 313 record is information about the write speed supported by the media, and it can be expressed the lowest speed and the highest speed or separately supported writing speeds. For example, it can be expressed as 1x, 2x, 4x or 6x.

Table 320 information defining parameters include the speed of 321 account and layer 322 records are related to the account settings stored in the table of parameters of the information structure, and information 323 specify the write policy (Sz), indicates how the strategy account associated related to the account settings.

The speed of 321 account refers to the write speed to apply regarding the capture parameters table parameters of this structure information is the AI on the disk, and layer 322 recording refers to recording layer to which you apply regarding the capture parameters table parameters of this structure with information about the disk. Information 323 instructions Sz indicates Sz recorded in the table of parameters of the information structure. Of course, this must be determined characteristic number for each Sz.

In this case, the characteristic number NW is not limited to one strategy account and this specific number can be increased to multiple numbers, when the standard upgrade by adding other information not related to the NW. In other words, when you create the first standard may be determined that if the information specifying the write strategy in the structure information about the drive this disc for this standard specifies "1", related to the write parameters in the parameter table structure information about the disk indicate Sz A. thereafter, if required Sz B, when the standard update by adding new transmission speed, then the updated standard will have two Sz, Sz A and B. Sz as it is impossible to say that only add the new rate and its accompanying NW when updating the standard, you can expect add other information (alpha). Accordingly, it is possible to ensure that if the information specifying the NW in the structure of the disc information question what about the drive to the new standard indicates "2", it is relevant to record the parameters in the parameter table structure of the disc information, which includes the function of alpha indicate Sz A, or you can guarantee that if the information specifying the NW in the structure of the disc information indicates "3", related to the write parameters in the parameter table structure of the disc information, which includes the function of alpha indicate Sz B. Thus, the structure of the disc information is recorded on the disc. When many different types of carriers in accordance with this standards update is loaded into the drive and reproduce the structure of the disc information recorded on data carriers, the drive may identify that if the information specifying the Sz is equal to 1 or 2, related to the write parameters in the parameter table structure information about the disk indicate Sz A, and if the information specifying the Sz is equal to 3, relating to the recording parameters in the parameter table structure information about the disk indicate Sz B. Because the standard will be continually updated, characterized by a number indicating Sz A, and characterized by a number indicating Sz B, can be added in accordance with your settings when the standard create for the first time.

Table 330 parameters include the pulse repetition period (Ttop) at the beginning of the recording, the pulse repetition period (Tmp) in the middle of the Dean records, the pulse repetition period (Tel) at the end of recording, the recording power (Pw), the power of removal (Pe) and power offset (Pb) as the recording parameters and according to a variant implementation of the present invention, includes, in particular, the speed of the recording layer recording information and guidance NW. In addition, table 330 parameters may include related to playback parameters that depend on the implementation.

Thus, using the fact that the table definition parameters in the structure of the disc information according to a variant implementation of the present invention includes a recording speed, a recording layer, and information specifying the NW, by finding the table information defining parameters can be known, what speed record, which record layer and what NW has the structure of the disc information. In other words, in order to quickly get relevant to recording information, the present invention specifies using the table information parameters, and determine what the speed of the recording layer of the recording and Sz recorded in the table data structure on disk.

For example, it is assumed that there are 2 layers of record supported write speeds : 1x, and there are two NW - SS and SS. At this time, the drive may know from the table information defining parameters which MSE of the spine and the recording layer should be applied regarding the capture settings, stored in the table of parameters of the information structure. In addition, the information specifying NW drive can know what NW this structure information about drive going to use, instead of reading related to the write parameters stored in the parameter table. Thus, in the embodiment of the present invention, the writing speed and recording layer, which will be applied to this structure of the disc information, specified in the speed of recording and field recording layer, respectively, in the table definition parameters, and SS specified by the information specifying Sz="1", and SS specified by the information specifying Sz="2". Doing so can be known recording speed and the recording layer are related to recording parameters stored in the parameter table, not even sequentially reading information such as Ttop, Tmp and Tel, table settings, you may know at least what Sz are related to the account settings stored in the table of parameters of the information structure on disk.

For example, assuming that the speed is 1x and the drive that is going to record data on the recording layer 0 only supports CS to write data, the drive must only use the parameters SS defined in the table data structure on disk, the Le location patterns of information about the disk, having information about the drive for speed 1x, recording layer 0 and the disc information for SS, table information defining parameters of the corresponding structures drive information among items of information about the disk. In doing so, when data is written, the drive can quickly find the entry that corresponds to the information parameters from the table information to determine the parameters so that the disk utilization can be improved.

4 is an exemplary diagram that explains the compatibility of the structure of the disc information according to a variant implementation of the present invention.

In the first standard information specifying NW, which can be applied to the initial speed 1x, indicate "1". When you add a new rate, i.e. when you add a 2x speed when upgrading the first standard to the second standard, add new Sz B, which can be used to speed 2x, the information specifying Sz indicate "2". In addition, when you add speed 4x, when the second standard update to the third standard, the new Sz C, which can be used to speed 4x, and 2x speed, refer to "3". Thus, giving the rooms consecutively in order of appearance Sz, many NW can be controlled and compatibility between standards can be easily achieved.

Thus, assuming that there is risk of type Sz A, B and C, and a rule specifying Sz is set as A=1, B=2 and C=3, if the information specifying C3 "1", it indicates Sz A, if the information specifying C3 "2", it indicates Sz B, and if the information specifying C3 "3", it indicates Sz C.

Referring to figure 4, shows the drives of the three standards (rewritable information storage media).

The disk 410 version 1.0, which corresponds to the first standard, has the characteristics of a 1x, 2 layer recording and A. Sz Disk 420 version 1.1, which corresponds to the second standard, has the characteristics of a 1x and 2x, 2-layer recording and NW A and B. Sz Disk 430 version 1.2, which corresponds to the third standard, has the characteristics of speed 1x, 2x and 4x, 2-layer recording and NW A NW B NW C.

Thus, assuming that the first standard is gradually update to the third standard, next will be explained the procedure by which the structure of the disc information recorded in the information area of the disk, and the destination information specifying Sz.

First, for convenience of explanation, it is assumed that A NW can be applied only to a 1x all standards, NW B can only be applied to speed 2x in the second and third standards and Sz C can be applied only to the speed of 2x and 4x in the third standard.

In General, when adding a new speed transmission requires new Sz and using the structure definition information about the disk and write the patterns on the media according to a variant implementation of the present invention, as described above, it is possible to ensure compatibility between the standards.

For example, if a rewritable information carrier 430 data produced in accordance with the third standard is placed in the drive 421, supporting the second with the standards, the drive 421 can quickly get information about the disk corresponding to the second standard structure of the disc information recorded in the information area of the disc rewritable information carrier 430 data from the table information defining parameters, while maintaining compatibility. Thus, when a rewritable information carrier 430 data is placed in the drive 421, if the drive 421 is going to write data on the first recording layer of the medium 430 write speed to 2x, then drive 421 first finds the structure of the disc information, in which the values of the table information defining parameters are equal (the speed of the recording layer recording information specifying NW)=(2, 1, 2), among the structures of the drive information area of the information on the disk medium 430 and with the help of addressing related to the recording parameters in the parameters table, this structure of information on the disk can be write data. The reason for the search of information structure on the disk with the information specifying Sz="2" is that NW B is the only explanation which can be applied to the transfer rate of 2x the drive supports the second standard. In addition, in the present embodiment, "2" is the only characteristic number, which indicates Sz B.

Using control structures information on the disk can guarantee the SQL scalability, as well as compatibility with other media, and therefore the present invention has the advantage that it provides the ability to adapt to a future increase in the number of recording layers, recording rates and NW. In addition, through the drafting of these rules can be achieved uniformity and compatibility standards between the rewritable information storage medium and information storage medium write-once.

Many structures information about the disk, which are described above, are recorded in the information area of the disk and stored in advance, when the disk is manufactured. For example, as shown in figure 2, they can enroll in a pre-recorded area of the input field. However, this area is only an example and the above-mentioned structure can be written in any field that can store information about the disk on the disk, which may be available in the future.

In addition, the explanation of the structures of the disc information, which is presented above, specifies the logical structure information about the disk and does not limit her physical structure. That is, the structure of the disc information is not limited by the fact that the structure of the disc information is actually divided into the physical area of the table of General information, table information to determine parameter and table settings, instead, the information stored in the structure information about the disk, can logically be divided as shown in the embodiment of the present invention.

Pig diagram, which shows a variant implementation of the recorder and/or playback according to a variant implementation of the present invention.

Addressing pig, the recording and/or playback includes module 2 write and/or read module 1 control.

Module 2 recording and/or reading has the head and other parts, and writes the data to disk and/or reads data from the disc 100, which is an optical recording information storage medium on which is recorded the structure of the disc information according to a variant implementation of the present invention.

Module 1 control module 2 recording and/or reading so that data is written and read from the disk 100 according to a predetermined file system.

In particular, when the disk 100 is loaded, the module 1 according to a variant implementation of the present invention controls the unit 2 recording and/or reading so many structures of the disc information is read from the disk 100, is found in the structures of the information about the disk structure information about the disk, as appropriate to the recorder and/or playback, and in the line is the cation of the parameters found in the structure of the disc information data recorded on the disk 100 or read from it.

Module 1 includes a system controller 10, the interface 20 of the master device, the digital processor 30 signals (DSP), high frequency (HF) amplifier 40 and the servo system 50.

When writing data interface 20 of the master device receives the predefined write command from the host device and transmits this command to the system controller 10. The system controller 10 controls the DSP 30 and the servo system 50 to perform this team entries accepted from the interface 20 of the master device. Error correction DSP 30 adds additional data such as parity, data received from the interface 20 of the master device, and the data that will be written, performs encoding by using error correcting code (ECC) to generate the ECC block, which is block error correction, and then modulates the generated ECC block in a predefined manner. RF amplifier 40 converts the output data from the DSP 30 to the RF signal. Module 2 recording and/or reading, which has a head that writes the transmitted RF 40 RF amplifier signal on the disk 100. The servo system 50 receives the input command required for servo control from the system controller 10, and the servo system controls the head module 2, the recording and/or reading. In particular, the system controller 10 according to a variant implementation of the present invention, sityva the t many structures information about the disk, recorded on the disc 100, and finds the structure of the disc information corresponding to this recorder and/or playback of the table information defining parameters of structures with information about the disk. For example, the system controller 10 searches the recording speed, recording layers and information specifying Sz recorded in tables information defining parameters to find a table definition parameters with the same information as the write speed of the system controller 10, the recording layer, on which the system controller 10 is going to write data, and information specifying the NW, which supports the system controller 10. Then, turning to the related account settings, which includes the table structure of the disc information, which includes a table defining parameters, the system controller 10 controls the elements of module 1 control, so that configures each element of the module 1 management, and data is written to disk 100 according to this configuration.

When playing a data interface 20 of the master device has accepted the command playback from the master device. The system controller 10 performs initialization necessary to play. Module 2 recording and/or reading directs the laser beam onto the disk 100 and vyrabatyvat the t optical signal from the laser beam, reflected from the disk 100.
