In addition, dish information is registered as uncertain message unit according to the present invention, and it can for example be seen as first or second information.
Fig. 1 and 2 represents the structure according to CD of the present invention, and wherein any recordable CD all can be applicable to the present invention.Recordable disc for example can be CD-RW or CD-WORM.
With reference to showing the Fig. 1 of the CD with a recording layer, Lead-In Area is provided as the directorial area on the inner circumference area of CD, and leading-out zone is provided as the directorial area on the outer circumferential area of CD.In inner circumference area, separation provide prerecorded zone and can rewriteeing or the write-once district.
In BD-RE and BD-WO technology, prerecorded zone is known as the PIC district, wherein records permanent information and control data, and records dish information in the PIC district.
The data field is made up of with outside free area ISA and OSA user data area and inside, records user data in user data area, and inside and outside free area is used for replacing the data of defect area.Under the situation of BD-WO dish, provide temporary defect management area (TDMA) to come record defect information and be used for common management.At the next TDMA that do not need of situation of BD-RE dish, the BD-RE dish has the respective regions of reserving appointment.
But the present invention is tending towards providing a kind of method that writes down and/or reproduce the dish information (DI) of required dish control information as dish that writes down in prerecord or posting field.Clearly the recording method in prerecorded zone also can be different is applied to every kind of dish.Under the situation of BD-RE and BD-WO dish, prerecorded zone is to use the PIC district that is used to obtain dish information of the biphased high frequency modulated signals record that reproduces according to the special playback method.
Fig. 2 represents to have the CD of double record layer, and the inner circumference area of its mid-game has the Lead-In Area with corresponding first recording layer of leading-out zone (layer 0) of second recording layer (layer 1).
In this case, in each Lead-In Area and leading-out zone, provide a PIC district, and in each PIC district, write down identical dish information (DI).
Fig. 3 represents according to the present invention formative PIC district.In the process of the dish information (DI) in the PIC district of configuration BD-RE or BD-WO dish, a smallest record unit is one bunch, and 544 bunches constitute a fragment as a upper strata record cell, and 5 fragments formation PIC districts.Dish information is recorded in the front beginning bunch of the first fragment IF0.The writing speed that every recording layer and corresponding CD are allowed is with the plural form disc information.A dish information comprises 112 bytes, is also referred to as sometimes to be dish information (DI) frame.In addition, in order to deal with the loss of dish information, the dish information of identical content is repeatedly recorded in each front head bunch of remainder of described fragment.In each dish information, comprise the information of representing the respective record layer, the information of representing writing speed and write policy information accordingly with writing speed.In the process of record and reproduction CD, utilize this information, to provide best Writing power to each recording layer and each writing speed.
In order to obtain the dish information relevant from a plurality of dish information with the specific speed of specific recording layer, need the positional information of each dish information of record, also it can be called " DI frame pointer ".For example, if having four recording layers and each recording layer can use four writing speeds, then need at least ten six dish information to overcome inconvenience, and no matter when need the value of particular plate information, system all must the whole dish information of search.Therefore, the positional information of respective disc information (DI frame pointer) can overcome this inconvenience.
4A to 8 describes each embodiment according to method with the method for record customizing messages of configuration dish information of the present invention in detail below with reference to accompanying drawings.
Fig. 4 A is a diagrammatic sketch according to the dish information of first embodiment of the present invention record to 4C.
Fig. 4 A represents to be used to explain the structure of the dish information of first embodiment of the invention.
With reference to Fig. 4 A, be used to the information of coiling a sequence each all be to decide and come record by 1 byte by a sequence number.For example, described information is recorded in the 5th byte in the dish information, and it is named as " the DI number of frames in the DI piece ", and simply by " 00h, 01h, 02h ... " represent.That is, if the information of the 5th byte is " 00h ", then it means it is the 1st dish information.If the information of the 5th byte is " 15h ", then it means it is the 16th dish information.In order to write down the positional information of particular plate information, the invention is characterized in that the DI frame pointer is decided by the combination of the information of the information (writing on the every velocity shifts pointer in N and the N+1 byte) of the position of the 1st dish information that indicates every writing speed and the position of pointing out the dish information relevant with the recording layer that it is applied each writing speed (write on layer 0,1,2 and 3 pointer in M and the M+1 byte).In this case, described information is recorded in the separate areas respectively.
And, the invention is characterized in and with the form of respective disc information sequence (for example indicate as the information of the position of every writing speed the 1st dish information of the 5th byte information in the dish information identical information representation by representing the respective disc information sequence, 00h, 03h etc.) come record, specify a numeral (skew) that is added in the 1st positional information according to corresponding writing speed with the information of the position of pointing out the dish information relevant with the recording layer that it is applied each writing speed.
In addition, in the first embodiment of the invention shown in Fig. 4 A applicable writing speed by 1x speed (1X), 2x speed (2X), the 3rd speed (3
RdX) or the 4th speed (4
ThX) representative.For example, definable the 3rd speed (3
RdX) or the 4th speed (4
ThX) be used for specifying respectively 4x speed and 6x speed.
With reference to Fig. 4 A, a specific byte (N or N+1 byte) is cut apart by 4 bits.And each position that can use the 1st dish information of writing speed is written in each 4 bit.Each position that can use the 1st dish information of writing speed equals to be recorded in dish information sequence information in the 5th byte.Because distributed 2 bytes (N and N+1 byte), so can represent four writing speeds altogether.If have five or how different writing speeds, for example N byte, N+1 byte, N+2 byte etc. also are added to wherein then more byte.In addition, will in the second embodiment of the present invention shown in Figure 5, describe the another kind of method of extended byte in detail after a while.
Its positional information of using the recording layer of each writing speed is recorded in another byte (M or M+1 byte) in the dish information to indicate the numeral (skew) that each writing speed adds in the 1st dish information.That is,, not only can represent the position of every writing speed the 1st dish information, can also represent the position of the recording layer that each corresponding writing speed applies, can represent the whole positions of 16 dish information thus by 4 bytes altogether by above-mentioned method.
In the application of first embodiment of the invention, indicate a positional information specific or a dish information to distribute 1 byte to represent by only giving the reserved area in the dish information.If 16 dish information are arranged, then need 16 bytes.Therefore, can in the positional information of specifying whole dish information, overcome the expansion problem of standard in the future.
Fig. 4 B represents that wherein the 3rd and the 4th writing speed is set to 4x speed and 6x speed respectively according to the example of the positional information of representing 16 dish information under the situation of four writing speeds and four different recording layers of each writing speed of first embodiment of the invention.In N and N+1 byte, the position of the previous agreement of the 1st dish information of each writing speed is represented by 4 bits that distribute." 0000b " as preceding 4 bits of N byte has such implication: specify for the position of the first dish information of 1x speed and coil information accordingly so that it becomes with sequence number " 00h "." 0100b " as following 4 bits of N byte has such implication: specify for the position of the first dish information of 2x speed and coil information accordingly so that it becomes with sequence number " 04h "." 1000b " as preceding 4 bits of N+1 byte has such implication: specify for the position of the first dish information of 4x speed and coil information accordingly so that it becomes with sequence number " 08h ".And, have such implication as " 1100b " of following 4 bits of N+1 byte: specify for the position of the first dish information of 6x speed and coil information accordingly so that it becomes with sequence number " 12h ".
In M and M+1 byte, record the position that it is applied the recording layer of each writing speed.And enforcement power of the present invention support is four recording layers (layer 0, layer 1, layer 2 and layer 3) altogether.Therefore, the position of having pointed out the 1st recording layer L0 of every writing speed as " 0000b " of last 4 bits of M byte.The position of having pointed out the 2nd recording layer L1 of every writing speed as " 0001b " of following 4 bits of M byte.The position of having pointed out the 3rd recording layer L2 of every writing speed as " 0010b " of last 4 bits of M+1 byte.And, the position of having pointed out the 4th recording layer L3 of every writing speed as " 0011b " of following 4 bits of M+1 byte.
In the superincumbent explanation, recording layer information means the numeral (skew) of adding in each the 1st positional information under each writing speed.For example, if the recording layer positional information be " 0000b " (L0), then the numeral that will add (skew) is " 0 ", makes recording layer information mean corresponding the 1st dish information under every writing speed.And, if the recording layer positional information be " 0010b " (L2), then the numeral that will add (skew) is " 2 ", makes recording layer information mean the next one the 2nd dish information in corresponding the 1st dish information under every writing speed.
Be intended to detect in system under the situation of 4x speed disc information of the 3rd recording layer, detect the position of the 1st dish information under the 4x speed from preceding 4 bits (08h) of N+1 byte, then the position of the recording layer under the corresponding writing speed of preceding 4 bit-detection of M+1 byte.This has just obtained arriving at the dish information of the 3rd position (08h) of the dish of the 1st under 4x speed information position.The position of the dish information that therefore, will finally search for becomes the have sequence number dish information of " 11h ".
If Fig. 4 C represents the example that always has eight different dish information age dial plate information positional informations under two recording layers and each recording layer have the situation of four different writing speed information according to the first embodiment of the invention among Fig. 4 A.Therefore its detailed method for expressing identical with described in Fig. 4 B will look into the distance this detailed method for expressing in following explanation.Yet what present embodiment related to is the situation that only has two recording layers, does not need thus the M+1 byte with information of the 3rd and the 4th recording layer is arranged to " 1111b ".If the information of detecting " 1111b ", then system identification goes out corresponding recording layer and does not exist.Clearly value " 1111b " also available another discernible value substitutes.
Fig. 5 is that the second embodiment of the present invention can be applicable to the conceptual expansion of the first embodiment of the invention among Fig. 4 A is become the situation of more writing speed of adding or recording layer according to the diagrammatic sketch of the dish information of second embodiment of the invention record.
That is, the first embodiment of the present invention relates to the method for a kind of given disc information position, its maximum four recording layers and four different writing speeds of the maximum appointment of each recording layer of specifying.If the quantity of recording layer or writing speed surpasses five, then the first embodiment of the present invention just can not be represented them.Therefore, according to a second embodiment of the present invention for coiling the more byte of information distribution to overcome such problem.For convenience of explanation, one group of initial 4 byte N, N+1, M and M+1 are named as the 1st group field, and additional 4 bit X, X+1, Y and the Y+1 of another group is named as the 2nd group field.
The recording method of the 2nd group field of carrying out in the mode identical with the 1st group field by in separate areas respectively record indicate the 1st dish information under the whenever additional writing speed the position information (writing on the offset pointer 5-the 8th writing speed in X and the X+1 byte under) and indicate and the information of the position of dish information that its addition record layer that applies each writing speed is correlated with (promptly writes on layers 4 in Y and the Y+1 byte, 5,6 and 7 pointers) and the combination of information by record solve.
And, support to use the existence whether information of the 1st and the 2nd group field by in the reserved area of 1 byte records in dish information.For example, by L byte in the utilization dish information, described information is named as " byte of using the DI frame pointer ".Under the situation of the positional information of only using the 1st group field [N is individual, N+1 is individual, M is individual and M+1 byte] given disc information, main fields is set at " 00000000b ".And under the situation of the positional information of using the 1st group field [N, N+1, M and M+1 byte] and the 2nd group field [X, X+1 is individual, Y is individual and Y+1 byte] given disc information, main fields is set at " 00000001b ".Therefore, can determine the byte (group field) of the positional information of current use.
Therefore,, then only use the 1st group field, second group field all is set to " zero ", and in L byte, writes " 00000000b " if each quantity in writing speed and the recording layer is equal to or less than 4.In writing speed quantity and recording layer quantity any one needs under the situation of five different information at least, and the 1st and the 2nd group field all is utilized and writes " 00000001b " in L byte.
Fig. 6 A to 6D is that wherein intrinsic " recording layer information " and " writing speed information " are recorded in the dish information as positional information according to the diagrammatic sketch of the dish information of third embodiment of the invention record.
With reference to Fig. 6 A, be used to the information of coiling a sequence each all be to decide and come record by 1 byte by a sequence number.For example, described information is recorded in the 5th byte in the dish information, and it is named as " the DI number of frames in the DI piece ", and simply by " 00h, 01h, 02h ... " represent.That is, if the information of the 5th byte is " 00h ", then it means it is the 1st dish information.If the information of the 5th byte is " 07h ", then it means it is the 8th dish information.And, will represent by the specific bit in the specific region (K byte) that will be recorded in the dish information by recording layer information and writing speed information that corresponding dish information is used.
For example, recording layer information is recorded in preceding 4 bits of K byte, and writing speed information is recorded in following 4 bits of K byte.And, can following definition record layer information.If recording layer information is " 0000b ", then it means it is the 1st recording layer L0.If recording layer information is " 0001b ", then it means it is the 2nd recording layer L1.If recording layer information is " 1111b ", then it means it is the 16th recording layer L15.
And, can define writing speed information in every way.For example, if writing speed information is " 0000b ", then it means it is 2x speed.If writing speed information is " 0111b ", then it means it is 8x speed.If writing speed information is " 1111b ", then it means it is 16x speed.
Therefore, this define method of recording layer or writing speed information can define according to system or by norm-setting one different mode.In addition, can also come definition record layer or writing speed information by it being distributed 1 byte.
