Description
Technical field
But the present invention relates to carry out in each data area the light information recording method and the device for optical information recording of the record of data for the optical information recording medium that has a plurality of recording layers and on each recording layer, have the data area of recorded information respectively, the signal conditioning package that comprises this device for optical information recording, but and have a plurality of recording layers and on each recording layer, have the optical information recording medium of the data area of recorded information respectively, and the computing machine that makes device for optical information recording carries out the program of the record of the data in each data area of this optical information recording medium, and the recording medium that has write down this program.
Background technology
The spy opens and discloses a kind of information record carrier in the 2001-126255 communique, under the situation that the information recording carrier with a plurality of recording layers is write down, from beginning to carry out record, avoid the decline of the quality of record data from light input side recording layer far away relatively.
Record type disk as DVD has DVD+R, and physical characteristics approaches the DVD-ROM dish, is the CD good with the interchangeability of DVD-ROM driver.DVD+R be can't rewrite data single write medium, need carry out data recording continuously.
In addition, be the data that unit writes afterwards for the DVD-ROM driver is read with the file, generally in advance the zone of log file information is retained in the front end of section (session), when section finishes in reserve area the fileinfo to record data carry out record.
As previously mentioned, the data recording of DVD+R is necessary week to begin continuous recording in coiling, but carries out record by posting field being divided into a plurality of tracks (section of being called among the DVD+R (fragment)), thereby can write down the front end area of section afterwards.
In addition, even under the situation that section is through with,, also can carry out the writing afterwards of data after section finishes by newly appending section.Like this, in DVD+R, adopt multiple road, multi-region segment record mode.
Recently, extensively carry out the high speed of record type disks such as DVD+R, the research and development of high capacity, as one of its means, propose to have with the playback interchangeability of the special-purpose DVD dish of the playback of single-surface double-layer, recording layer is that the DVD+R dish of single-surface double-layer is (hereinafter referred to as DVD-dual layer+R).
The memory capacity of this DVD-dual layer+R is 8.4Gbyte, and the data capacity that with respect to the existing recorded layer is the DVD+R of one deck is 4.7Gbyte, approximately has the memory capacity of twice.In addition, the data that write down among DVD-dual layer+R can be by the DVD player of the playback of the special-purpose DVD dish of the playback that can carry out single-surface double-layer, and perhaps the DVD-ROM driver is read.
Logical address among DVD-dual layer+R begins continuous dispensing from the start address of the data area of the recording layer of ground floor, and the end address, data area of ground floor is continuous to the logical address of the data area start address of the second layer.Thereby in the record to DVD-dual layer+R, the user can write down and not can be appreciated that recording layer is divided into two-layer.
Here, in DVD+R, thereby the data area is with a plurality of cut zone, i.e. section or be that unit cuts apart and carries out record with the section.When the cutting apart of these data areas, be necessary not make the user to recognize that recording layer is divided into two-layerly and carry out.
For example, be under the situation in unit partition data zone with the section, the general user is undertaken this by the specified section size to be cut apart.At this moment, incomplete section (IncompleteFragment) as the terminal section in the data area is split into the reservation paragraph (Reserved Fragment) of the size of appointment and new incomplete section.
Here, be positioned at the start address of terminal section under the situation of data area of recording layer of ground floor, according to the data designated size, consider the situation of reservation paragraph above the data area of the recording layer of ground floor, but, carry out data recording so can't surpass the scope of data area of the recording layer of ground floor because the data area of the recording layer of ground floor fixes.
But, to cut apart by limiting such section, the user need manage the scope of the data area in each recording layer, and that considers the user easy to usely then has a unfavorable problem.
Therefore, as continuous single data area, the data area of two recording layers, if can cross over cutting apart of these two recording layer sections of carrying out, section etc., then can carry out with section, section etc. is the cutting recording of unit and do not make the user recognize a plurality of recording layers.
In addition, in DVD+R, the Lead-In Area in the section that second section is later is called introduces district (Intro), and the leading-out zone of the section before the terminal section is called end zone (Closure).This introducing district and end zone are the data with user data attribute, with the record format record of regulation.
Usually, under the situation of the enterprising line data record of DVD+R, data are with the form record of file.At this moment, write down the file control information that is used for the leading subscriber data message in the file management zone of preparation in addition with the zone that is used for the user data entity.
The regulation zone of this document management information general record in section front end 16 sectors of user data area (for example, from).In the multi-region segment record, write afterwards under the situation of section, upgrade this document management information and the regulation regional record of new section.
That is, exist with certain section in file control information comprise and the entity file associated management information that is recorded in the user data in this section, and be recorded in this section before section in the relevant management information of entity of user data.
Thereby, for the file of reading and recording in multi-region section DVD+R, start address that need specific final section.
If with the corresponding driver of multi-region section DVD+R, then driver self detects multi-region segment information (for example, the start address of each section, end address), the information of final section can be notified to the user.Even with the non-corresponding existing DVD-ROM driver of multi-region section DVD+R, the user also can obtain the information of final section by using specific drive software (such drive software is called the multi-region segment driver).
Promptly, in such multi-region segment driver, judge the start address of next section from user data size and the end zone size of this section, the introducing district size of next section of first section, reset assigned position in the introducing district of next section, and the zone field from be recorded in this zone is obtained the size of next section.
Handle and advance along the section that is present on the dish successively by this zone detection, thereby can detect final section.Have user data attribute (being identified as user data) by introducing district and end zone, and the introducing district is big or small, big or small the fixing in end zone can be realized this process by existing DVD-ROM driver.
In addition, in such DVD-dual layer+R etc., as previously mentioned, introduce district or end zone sometimes and cross over two recording layers under the situation of sector division etc. in that the data area of two recording layers is carried out as continuous single data area.Even under these circumstances, for by with non-corresponding driver of multi-region section DVD+R and the specific final section of multi-region segment driver, need introduce district and end zone cutting recording in the data area.

In addition, when the introducing district that writes down section 2, end zone, at the middle layer of layer 0 and 1 record, so that can reset by existing DVD-ROM driver.
The example of Fig. 8 C is illustrated in the single end zone state with the mode cut section of spanned record layer 52,53.
In section, set introducing district (first regulation that is record first specified data is regional) in the place ahead of user data area, set end zone (for the second regulation zone of record second specified data) in the wings, when this introduces two data zones of district or two recording layers 52,53 of end zone leap, to introduce district or end zone and be divided into two, and set each partitioning portion and carry out record in each data area.
In DVD+R, the size of data of introducing district and end zone is certain, and optical data recording/reproducing device 1 is considered these size of data and the start address of the user data area of detector segments.
Thereby, even in introducing district or end zone, cross under the situation of recording layer 52,53, carry out record, also the start address of the user data area of detector segments correctly by being divided into two data zones.
Fig. 9 A, Fig. 9 B, Fig. 9 C, Fig. 9 D are the figure that is used to illustrate that the section of the information recording/reproducing apparatus 1 of one embodiment of the present invention is cut apart.
In DVD+R, but record till in 1 section, being up to 16 sections.Between the section of adjacency, dispose the insertion piece of the empty data (dummy data) of 1ECC piece with user data attribute.
In other words, back one of previous, the terminal section of the initial section in section does not exist the insertion piece.In addition, inserting piece is section distinct area with adjacency.
In the example of Fig. 9 A, the reservation paragraph 1 that on layer 0, exists the start address of section and end address to determine.Section 1 later not posting field is handled as incomplete section, and the end address, data area of layer 1 is temporarily given in the end address of section 2.
Determined in the section that exists in the section end address section, be that the information of reservation paragraph 1 is recorded among the SDCB.Exist to insert piece between section 1 and the section 2, this insertion piece is recorded during user data in section 2.
Fig. 9 B represents will incomplete section 2 state that newly is divided into two sections with the form of user data area spanned record layer 52,53 ( data area 54,55).In this case, as previously mentioned, not exclusively the end address of section 2 is determined, becomes reservation paragraph 2.At this moment, the information of reservation paragraph 2 is appended in the SDCB, and the SDCB that upgrades is recorded in the zone of regulation.Generate new incomplete section 3 at the rear of reservation paragraph 2.
To data area 55 record data of layer 1 time, for the playback of the data of the start address that is recorded in data area 55, and recording layer inserts before data area 55.This layer is recorded when being inserted in the data area 55 of layer 1 being carried out data recording.
Fig. 9 C is the divided situation of border segment at recording layer 52,53.In this case, at reservation paragraph 2 and not exclusively between the section 3, promptly there is the insertion piece in the data area start address of layer 1, but will insert in the zone line (the 3rd regulation zone) that piece (the 3rd specified data) is configured in the layer 1 in the zone before layer 1 the data area 55 (perhaps, the front end of the data area 55 of layer 1 also can).Insertion piece under this situation is by the data recording of data attribute with expression zone line, and is recorded when the user data area to section 3 writes down.
That is, in DVD+R, the start address and the end address of section are recorded in the SDCB, therefore by the information in the reference SDCB can the section of obtaining start address.
In case section finishes, the data that then are recorded in the section are read based on the file control information that is recorded in from section start address assigned position.That is, in DVD+R, about the section that data recording has been finished, the segment information in the section is inessential, only necessity under the situation about writing down opening the section section of being divided into.
Thereby, become under the such section situation about cutting apart of insertion piece at the data area start address of the recording layer 53 that carries out the second layer, will not insert piece and be recorded in the data area.
Therefore, in the present embodiment, even the data area start address at the recording layer 53 that carries out the second layer becomes under the such section situation about cutting apart of insertion piece, insert data area 55 previous that piece is recorded in the recording layer 53 of the second layer, so can normally reset to the data of the data area start address record of the recording layer 53 of the second layer.
Fig. 9 D represents to insert the special recording method of piece, so intention goes up expression begins to carry out data recording from the layer 1 of the second layer section example of cutting apart.In this example, 54 and 55 the border section of carrying out is cut apart in the data area.In this case, shown in Fig. 9 D, the data area 54 of layer 0 all becomes reservation paragraph 1, and the zone line of the layer 1 in the zone before the data area 55 of layer 1 becomes the insertion piece, and the data area of layer 1 becomes incomplete section 2.The user can carry out the data recording that begins from the second layer by begin to carry out data recording from section 2.
Figure 10 be used for that the optical data recording/reproducing device 1 of key diagram 1 is carried out, as the process flow diagram of the light information recording method of one embodiment of the present invention.
The processing of Figure 10 is the light information recording method that the controller 6 (CPU) of the optical data recording/reproducing device 1 of Fig. 1 is carried out.Controller 6 is divided into two data zones 54,55 of two recording layers 52,53 of CD 51 a plurality of cut zone, promptly is unit with the section or is unit (step S1) with the section as continuous single data area.
Controller 6 uses described mode to carry out the record of data (step S2) with reference to Fig. 7 A～Fig. 9 D respectively in each cut zone of section or section etc.
Figure 11 is the example of the step S2 that carries out as optical data recording/reproducing device 1, illustrates that carrying out with the section is the process flow diagram of an example of concrete processing of situation of record of unit.
In the example of Figure 11, first section in the multi-region segment record and the section of final section removed in record.District and end zone introduced in record in the front and back of user data area.In the example of Figure 11, the section that can not carry out in the section is cut apart.
During beginning section record (step S11 is a "Yes"), controller 6 is obtained request recording address (step S12).
Then, whether controller 6 decision request addresses are the addresses (step S13) in the layer 0.Under the situation of the address in request address is layer 0, data recording (step S14) is carried out in the regulation zone in 6 pairs of layers of controller 0.
Controller 6 judges in the data recording of step S14 whether the record of the data area of layer 0 is finished (step S15).Under the situation that the record of layer 0 finished, controller 6 continues to transfer to the record to layer 1, in the zone line previous, i.e. layer 1 of the data area 55 of layer 1, the layer of recording prescribed size inserts piece (step S16) as shown in Figure 9 but here.Then, data recording (step S17) is carried out in the data area 55 of 6 pairs of layers 1 of controller.
On the other hand, under the situation about in step S15, the record of layer 0 not being finished, proceed to step S18.
In addition, under the situation of request address in layer 1, data recording (step S17) is carried out in the regulation zone in 6 pairs of layers of controller 1 in step S13.
Then, controller 6 judges whether the data recording in the section finishes (step S18).If data recording is not finished, controller 6 returns step S12, proceeds obtaining of request address.
On the other hand, under the situation that data recording has been finished in step S18, transfer to the section end process.Controller 6 is at first obtained and is introduced district's start address (step S19).Then, controller 6 is judged and is introduced district's start addresss whether in floor 0 (step S20).
Introduce in step S20 under the situation of district's start address in floor 0, the record (step S21) in district is introduced in the regulation zone in 6 pairs of floor of controller 0.
Then, whether controller 6 judgement in introducing district's record finishes (step S22) to the record of the data area of floor 0.
Under the situation about in step S22, the record of layer 0 having been finished, then transfer to record to layer 1.Controller 6 is recording layer 0 and layer 1 zone line (step S23) at first.Then, the remainder (step S24) in district introduced in the data area of 6 pairs of floor 1 of controller record.
On the other hand, in step S22, in floor 0, introduce under the situation that the district record finished, proceed to step S25.In addition, introducing under the situation of district's start address in floor 1 (step S20 is a "No"), the regulation regional record in the floor 1 is introduced district (step S24).
In the section end process, then carry out the end zone record.Here, at first obtain end zone start address (step S25), and judge that the end zone start address is whether in layer 0 (step S26).Under the situation of end zone start address in layer 0 (step S26 is a "Yes"), the regulation zone in the layer 0 is carried out the record (step S27) of end zone.Then, judge in the record of end zone whether the record of the data area of layer 0 is finished (step S28), under the situation that the record of layer 0 has been finished (step S28 is a "Yes"), then transfer to record layer 1.Here, recording layer 0 and layer 1 zone line (step S29), and to the remainder (step S30) in the end of record (EOR) district, data area of floor 1.On the other hand, in floor 0, finished under the situation of introducing district's record (step S28 is a "No"), finished a series of processing.In addition, (step S26 is a "No") proceeds to step S30 under the situation of end zone start address in layer 1, and to the regulation regional record end zone (step S30) in the layer 1.Above section end process finishes a series of processing after finishing.
More than in Shuo Ming the processing, CD 51 is carried out the record of user data, insertion piece, introducing district, end zone, zone line etc.The record of the user data in handling about this etc. is carried out by reference Fig. 7 A～Fig. 9 D mode of stating of chatting face to face in the past.
In this example, illustrated except first section and final section be the data recording of unit with the section, but the processing under the situation of record first section or final section is too.Under the situation of first section record, replace introducing district and record Lead-In Area, under the situation of final section record, replace the end zone and write down leading-out zone.In this case, the record of Lead-In Area leading-out zone similarly carries out with the introducing district that illustrates with reference to Fig. 8 A-Fig. 8 C, the record of end zone.
In addition, in the section end process, write down the zone line of each recording layer 52,53, but be not the Zone Full of record zone line, but the zone of its part of record is also passable in can carrying out the scope of exchanging with the playback of existing DVD-ROM driver.
