To refer in detail to the preferred embodiments of the present invention now, illustrate example of the present invention in the relevant drawings.Any possible place, same Reference numeral will be used for whole accompanying drawings to relate to same or similar parts.For convenience of explanation, Blu-ray disc (BD) is as the example according to CD of the present invention.Yet, it is evident that with the CD that records control information thereon to be the principle of the present invention of feature, be applicable to DVD-RAM/-RW/+RW/-R/+R of DVD family series for example etc. in the same manner.
In addition, although the term of using among the present invention can from the current term of knowing, choose, yet some term choose arbitrarily by the application under certain conditions, thereby their implication is explained in following instructions in detail.Therefore, the present invention need understand by the implication that the relational language of being chosen by the application is represented, rather than the simple name of term itself or implication.
At first, the expression of " control information " in the instructions of the present invention comprises the zone of the various information that are used for video disc recording/playback.And control information provides the prerecorded zone in CD or is used for the public appointed information of the embossed areas of CD user by CD manufacturer.Yet, also be provided in recording areas but control information not only is provided in prerecorded zone.But the optical disc information in prerecorded zone or the embossed areas can also be replicated in recording areas.And they only are exemplary.
Therefore, " the configuration control information " among the present invention means in CD and disposes control information in mode of the present invention.And, " record " but implication be applicable to disc manufacturer in making the process of associated optical disc with the control information prerecord in CD a kind of situation and user or system are recorded in control information another kind of situation among the recording areas in the CD afterwards.
Especially, control information is called " optical disc information " or " physical format information " among the DVD-RAM/-RW/+RW/-R/+R among the BD.Therefore, it is evident that technical background of the present invention is applicable to " physical format information " among the DVD-RAM/-RW/+RW/-R/+R in the same manner.For the ease of explaining that " optical disc information (after this breviary is DI) " that will be relevant with the situation of Blu-ray disc (BD) be as example.
Fig. 1 is the structural drawing according to CD-R of the present invention, and wherein CD-R is corresponding to rewriteeing Blu-ray disc (BD-RE) and write-once Blu-ray disc (BD-WO).
Fig. 1 has shown the single-layered disk that has a recording layer according to of the present invention.
With reference to Fig. 1, Lead-In Area provides the directorial area as the Nei Zhou district of CD, and leading-out zone provides the directorial area as the perimeter region of CD simultaneously.
Prerecorded zone is the zone that has write data in making CD, and the data that at all can not carry out in prerecorded zone of user or system write whereby.In BD-RE/WO, prerecorded zone is called PIC (fix information and control data) district.And above-mentioned optical disc information (after this being called " DI ") is recorded among the PIC district as the required information of video disc recording.
In the data field, provide wherein the user data area of the real data of recording user and the spare area ISA and the OSA of the defective data that replacement generated.Especially, be provided for the TDMA (temporary transient defect management) of recording defect and total management information to described CD-WORM such as BD-WO.In the situation that can rewrite BD (BD-RE), thereby do not need the described zone of TDMA to be left the reserved area.
Fig. 2 is according to the structural drawing of read-only Blu-ray disc of the present invention (BD-ROM), wherein shows the individual layer with a recording layer.
With reference to Fig. 2, by the Zone Full of hole prerecord read-only optical disc.And, carry out record in the same manner to management and data field.Because the PIC district of recording disk information wherein comprises the hole in the BD-ROM situation, thus it be appreciated that for the cluster that constitutes by the 2K*32 byte to similar in the data field.The above-mentioned PIC district of BD-RE/WO among Fig. 1 is different with BD-ROM in configuration.That is, in being different from the corresponding PIC district of data field, carry out two-phase RF modulation.
The present invention will provide the unified optical disc information configuration that is applicable to the Blu-ray disc that runs through BD-RE, BD-WO and BD-ROM family series, following detailed description.
Fig. 3 is the schematic diagram in PIC district among the BD.
With reference to Fig. 3, " cluster " expression smallest record/reproduction units among the BD, 544 bunches of set constitute a segmentation as a more senior record cell, and 5 segmentation set form the PIC district altogether.
In the preceding division header head of the first segmentation IFO bunch, dispose optical disc information.Repeatedly write down optical disc information and the writing rate that is applicable to corresponding CD at each recording layer, and an optical disc information is made of 112 bytes.Especially, the optical disc information that constitutes with 112 bytes is called optical disc information (DI) frame.In addition, identical content of repeated configuration optical disc information in the division header head bunch before each of all the other segmentations therefore can be corresponding with the disappearance of optical disc information.
Therefore, the BD optical disc information structure unification of the form of current discussion is applicable between BD-RE, BD-WO and the BD-ROM that system does not need independent hardware to manage identical optical disc information at each type whereby.In addition, can be used as no matter the common field of the optical disc information at the same position place in the same area of optical disc types is used.
Industrial applicability
Below explain in detail according to the method for configuration optical disc information and the optical data recording/reproducing device of using this method among the BD of the family row of being in according to the present invention by reference Fig. 4 to 9.
Fig. 4 has shown BD-ROM, BD-RE in family's series and the optical disc information of BD-WO, and wherein the minimum unit unification of each optical disc information is the identical size of 112 bytes.Reduced the load of the system of management optical disc information by the optical disc information that disposes identical size.
Especially, optical disc information is characterised in that and comprises common field that writes down the information that is common to read-only optical disc and CD-R and the specific field that writes down the specific information of each optical disc types.
And no matter optical disc types (BD-ROM, BD-RE, BD-WO), and the field record of same application is in the identical position that is called " common field " in optical disc information.
That is, suppose the N that optical disc information is interior
Th, M
ThAnd L
ThThe A that writes down in the byte, B and C field are regardless of optical disc types and the field of same application, so common field are recorded in the same position place of each optical disc information of BD-ROM, BD-RE and BD-WO.Common field places the preceding division header head place in the optical disc information substantially.Yet common field is not that forwardly title head place but can disperse in optical disc information as a unit group configured in one piece.Therefore, with after the corresponding position of specific field can change into common field.Do like this, unlike the common field at division header head place before placing, corresponding common field will be present in different positions rather than preceding division header head.
In addition, use the field that is called " specific field " that the non-same application of Saved Area Record writes down in the optical disc information of each optical disc types.That is, during same byte location place in the reserved area is present in the optical disc information of each optical disc types, it becomes specific field.
For example, " E field " is recorded in the P of BD-RE among Fig. 4
ThIn the byte.Yet, the P of BD-ROM or BD-WO
ThByte remains the reserved area to become specific field." F field " is recorded in the Q of BD-WO
ThIn the byte, the Q of while BD-ROM or BD-RE
ThByte remains the reserved area to become specific field." D field " is recorded in the R of BD-ROM
ThIn the byte, " D field " of BD-RE or BD-WO remains the reserved area to become specific field.
Yet, same field is being applied in the situation of another kind of optical disc types, respective field will be disposed in the respective byte position.For example, when " E field " was applied to the BD-WO of upgraded version or BD-ROM, " E field " was applied to P as BD-RE
ThThereby byte is changed into common field afterwards.
Simultaneously, only CD-R (BD-RE, BD-WO) needs " write strategy parameters " field, and corresponding to be used for read-only optical disc (BD-ROM) unessential specific field.Therefore, the X of BD-ROM
Th-111
ThByte is treated to the reserved area, and " write strategy parameters " field is written as the X of BD-RE or BD-WO simultaneously
Th-111
ThWrite strategy parameters information in the byte.
In addition, " write strategy parameters " field is had no chance to be applied to BD-ROM and will be remained specific field.Because " write strategy parameters " field is by various information, for example writing speed, recording power or the like constitute, so it need dispose identical content in the same position place (byte location) in respective field.This will explain in 8C at Fig. 8 A afterwards.
Determine to satisfy the compatibility between family's series CD whereby effectively according to above-mentioned principle in the position of the field that will be write down in the optical disc information in the serial CD by the BD of special use.
Fig. 5 to 7 has shown the specific field of the optical disc information of 112 bytes among the BD-ROM, the BD-RE that use above-mentioned principle and the BD-WO respectively.O

Fig. 8 A is respectively the interior speed information that writes down of control information of CD-R (BD-RE, BD-WO) and the structural drawing of write strategy parameters to 8C.Described in the book as described above, because wherein the field of recorded information is corresponding with the reserved area that is set to " zero ", so respective field remains specific field.
In the CD-R of for example BD-RE and BD-WO, " speed information " field comprises specified writing speed, dominant record speed and the smallest record speed of CD-R, and " write strategy parameters " field relevant with writing speed comprises important information, for example recording power, recording impulse timing or the like is to carry out the record of data.The data that write in the respective regions comprise all kinds, and public and above-mentioned explanatory principle specific field need be applied to be configured to be recorded in the information in the respective field.
Fig. 8 A has shown an embodiment according to the optical disc information of video disc recording of the present invention.
With reference to Fig. 8 A, the sequence of each optical disc information is determined by the sequence sequence number and by 1 byte records.For example, corresponding information is recorded in 5 in the optical disc information
