Description
The application be submitted on September 9th, 2005, application number be 200510103761.0, denomination of invention divides an application for the application of " optical disc recording apparatus, recording method and logging program and CD ".
Technical field
The present invention relates to optical disc recording apparatus, recording method and logging program and CD, be particularly related on the zone of any setting of the CD of Worm type with a plurality of recording layers or rewriting type, with management information come optical disc recording apparatus, recording method and the logging program of recording information signal in any order and with this recording device records CD.
Background technology
In recent years, (Digital Versatile Disk: digital multi-purpose disk) DVD-R of the CD of the Worm type of specification owing to can come the speciality such as animation of record reproducing high image quality and extensively popularized with high capacity as meeting DVD.This DVD-R is the CD of Worm type, can not delete the zone of original information that has write down and on this zone, rewrite other information again, because of rather than rewrite before the information that write down, but in continuous (writing afterwards) the new information of mending in Unrecorded other zone.Therefore, be record reproducing on the DVD-R with the CD of DVD-RAM one class rewriting type on the different management information of management information that writes down, record/Unrecorded zone is managed, and the writing afterwards of the information of carrying out.
Fig. 8 schematically represents an example of writing afterwards of the information on the DVD-R.Shown in figure, the posting field of DVD-R from the interior thoughtful periphery of DVD-R, is divided into R information area (R-Info.) 401, ingress area (Lead-in) 402, data area (Data Area) 403 and export area (Lead-Out) 404.
R-Info.401 is the distinctive zone of DVD-R, is made of power calibration area (PowerCalibration Area:PCA) 411 and record management zone (Recording ManagementArea:RMA) 412.Data area 403 is zones of user data.Ingress area 402 and export area 404 are buffer areas that the cross-line (オ-バ-ラ イ Application) of the record reproducing head during to 403 visits of data zones is gone up preparation.Described laterly going into boundary region and go out boundary region, is to work as the buffer area too.
Calling break bounds zone (Extra-Border zone) with the zone of data area 403 adjacency in the ingress area 402, have with described later and go into the roughly the same effect of boundary region (Border-in Area).The zone of clearly not preengaging in the data area 403 is called invisible Zone R territory (InvisibleRZone).Break bounds zone (Extra-Border zone), data area 403 and the export area 404 of the 421 expression new product DVD-R of Fig. 8, whole data area 403 is invisible Zone R territory (Invisible RZone).
Pre-zone of in data area 403, depositing the content of record from then on (for example 1 of 1 song of music, image, 1 file of computer data etc.), the just front in 403 invisible Zone R territory (Invisible RZone) formation Zone R territory (RZone) in the data area.Shown among Fig. 8 422, the data of content can begin record in order from the front of RZone.Also have, in the occasion of the size of not knowing content, also can be shown among Fig. 8 422, begin record in order from the front of invisible Zone R territory (Invisible RZone).
For the DVD-R that content record is through with becomes the state that can be reset by DVD player, must make and want that the zone of resetting and the buffer area regional record altogether of both sides thereof finish.This is because DVD player kerf (the カ Star テ イ Application グ) information that can not read DVD-R generally speaking, but groove (the ピ Star ト) information that only goes up record with plane between line (ラ Application De) is clue come playback of recorded data.
For this purpose, if the Rzone that has preengage has gone up residual not posting field, just make record finish (closure that is referred to as RZone) with filling out 0 data, shown among Fig. 8 423, clip the RZone that finishes as this record demarcated area (Bordered Area) and at break bounds (Extra-Border) with go out the data (being referred to as the closure on boundary) that boundary region (Border out) goes up recording prescribed.Also have, with the zone of the outside adjacency that goes out boundary region as relevant with next user data that is recorded go into boundary region (Border in) and in advance sky open.
Like this, the outside of boundary region (Border in) is just gone in invisible Zone R territory (Invisible RZone) from this.Herein, adjacency gone out boundary region (Border out) and goes into boundary region (Border in) to call boundary region (Border zone) altogether.Have, the occasion of additional record on DVD-R shown among Fig. 8 424, begins to come in order the data of recorded content from the front of invisible Zone R territory (Invisible RZone) again.If whole contents end of record (EOR) on DVD-R, just shown among Fig. 8 425, the data of recording prescribed (being referred to as perfect) on above-mentioned boundary closure and export area 404.Perfect DVD-R dish is the additional record data again.
The transition of the recording status of record management zone (Recording Management Area:RMA) 412 pairs of above-mentioned ingress areas 402, data area 403 and export areas 404 manage.RMA412 imports (RMA Lead-In) and record management data (Recording Management Data:RMD) formation by the RMA at the beginning of expression RMA412.Have before the RMA to connect and lose zone (Linking Loss Area:LLA), it has and is used to establish the required PLL of data playback synchronously and the effect between the runway of frame synchronization.
RMD is the management information that remains on to the recording status of the DVD-R in moment of data area 403 user data, and its size is the ECC piece (Block ロ Star Network) that symbol is corrected in miscount.This RMD is the timing before taking out DVD-R from optical disc recording apparatus etc., is recorded D as management information such as the position of this each boundary region constantly of expression and the position of each RZone.RMD in RMA zone 412, press RMD# 1 zone, RMD# 2 zone ... order, maximum can be recorded to RMD#700.Therefore, up-to-date management information just is recorded on the RMD zone of writing down the most close ingress area 402 in the RMD zone that finishes.
In the CD of this Worm type, the management information RMD of record is the important information of expression recording status on the RMA zone 412, if can not correctly reset, just can not write afterwards information again on this CD, thereby having proposed to improve the optical disc recording apparatus of the reliability of management information RMD, this is former is known (for example with reference to patent documentation 1).
In recent years, the user wanted that the capacity that writes down increased every year, was advancing the exploitation at the DVD-R of 2 layers of the single faces with two layers of recording layer of this requirement.Fig. 9 represents the summary posting field key diagram of an example of the DVD-R of 2 layers of this single faces.Shown in figure, the DVD-R that single face is 2 layers is the structure by ground floor recording layer 501 and second layer recording layer 502 laminations, calling ground floor from the near side of light picker.
Cut apart from interior thoughtful peripheral direction on the ground floor recording layer 501 and form R information area (R-Info.) 511, ingress area (Lead-in) 512, data area (Data Area) 513 and zone line (Middle Area) 514.Also have, cut apart from interior thoughtful peripheral direction on the second layer recording layer 502 and form R information area (R-Info.) 521, export area (Lead-out) 522, data area (Data Area) 523 and zone line (Middle-Area) 524.
That is, among the DVD-R that this single face is 2 layers, ground floor recording layer 501, with respect to the DVD-R of individual layer, the export area changes to zone line 514.Second layer recording layer 502 is structures roughly the same with ground floor recording layer 501, but, replaces ingress area 512 and is provided with export area 522.Ground floor recording layer 501 writes down to outer circumferential side from interior all sides, and second layer recording layer 502 writes down to interior all sides from outer circumferential side.
Also have, among the DVD-R that this single face is 2 layers, to second layer recording layer 502 records the time, as shown in figure 10, see through ground floor recording layer 501 by means of object lens 602 from the light beam 601 of light picker (not shown) emitting laser, focusing, optically focused on second layer recording layer 502.Therefore, the recording characteristic of second layer recording layer 502 is that record finishes or record is not different because of ground floor recording layer 501, and this is known.
Herein, if to the record of second layer recording layer 502 always by writing down of ground floor recording layer 501 the zone carry out, just do not mind the variation of above-mentioned recording characteristic.Herein, during to second layer recording layer 502 records, as shown in figure 10, the light beam 601 of laser is by means of object lens 602, by ground floor recording layer 501, optically focused on second layer recording layer 502, thus the record of the ground floor recording layer 501 that sees through with the light beam 601 of laser the amplitude in zone compare, the amplitude in recordable zone can be narrower on the second layer recording layer 502.Consider the constructional error of ground floor recording layer 501 and second layer recording layer 502, will make it narrower.
Herein, if to the record of above-mentioned second layer recording layer 502 always by writing down of ground floor recording layer 501 the zone this prerequisite of carrying out under, carry out words to the record of 2 layers of DVD-R of single face, shown in Figure 11 (A), on ground floor recording layer 501, write down the moment of information to a certain degree, by this zone of having write down, recorded information on second layer recording layer 502, ground floor recording layer 501 and second layer recording layer 502 can both be from interior all side opening entries, thereby improved convenience.
That is, in Figure 11 (A), to ground floor recording layer 501, shown in arrow 701, write down information from interior thoughtful periphery after, to the second layer recording layer 502 on it, shown in arrow 702, from outside thoughtful in the Zhou Jinhang record, form the Zone R territory (RZone) that record finishes.After this, to ground floor recording layer 501, shown in arrow 703, after having write down information from interior thoughtful periphery, to the second layer recording layer 502 on it, shown in arrow 704, from outside thoughtful in the Zhou Jinhang record, form the Rzone that record finishes, again to ground floor recording layer 501, shown in arrow 705, after having write down information from interior thoughtful periphery, to the second layer recording layer 502 on it, shown in arrow 706, from outside thoughtful in the Zhou Jinhang record, form the Rzone that record finishes.

Then, system controller 4 is calculated the beginning sector numbers of the above-mentioned white space 103a that occurs on the second layer recording layer 502 and is finished sector numbers (the step S14 of Fig. 4 (A)), in the table of the white space in the RMD posting field of in data-carrier store 7, having guaranteed, append the beginning sector numbers of the above-mentioned white space 103a that occurs on the second layer recording layer 502 and finish sector numbers, upgrade RMD, the RMD after this renewal is recorded on the R-Info.511 or 521 of CD 3 (the step S15 of Fig. 4 (A)).
The table of the white space in the RMD posting field that Fig. 6 (A) has represented to guarantee in the data-carrier store 7 of this occasion, the beginning sector numbers of the first white space 103a that has upgraded among the above-mentioned steps S15 is stored in the position 201 of N to N+3 byte, finishes the position 202 that sector numbers is stored in N+4 to N+7 byte.In addition, other place in the table is 0 data.After the RMD end of record (EOR), can take out CD 3 from optical disc apparatus 2.
After this, CD 3 optical disc apparatus 2 of packing into, or the like, the data of to a certain degree amount in (the Invisible RZone) 102 of invisible Zone R territory end of record (EOR) after, preengage the 2nd RZone, shown in Fig. 3 (B), in invisible Zone R territory (Invisible RZone) 102, form the RZone104 that record finishes, form the second reservation RZone105a successively with this outer circumferential side adjacency, invisible Zone R territory (Invisible RZone) 106, and on the second layer recording layer 502 between reservation RZone105a and invisible Zone R territory (the Invisible RZone) 106, produce the second white space 107a.
At this moment, optical disc apparatus 2 identical action when carrying out with above-mentioned RZone reservation, system controller 4 is calculated the beginning sector numbers of the above-mentioned second white space 107a and is finished sector numbers, in the table of the white space in the RMD posting field of in data-carrier store 7, having guaranteed, append and store them, upgrade RMD.The table of the white space in the RMD posting field that Fig. 6 (B) has represented to guarantee in the data-carrier store 7 of this occasion, the beginning sector numbers of the second white space 107a is appended the position 203 that is stored in N+8 to N+11 byte, finishes sector numbers and appends the position 204 that is stored in N+12 to N+15 byte.
Then, optical disc apparatus 2 is by record reproducing circuit 5 and light picker 9, shown in Fig. 3 (C), the information signal that record is wished on the second reservation RZone105a, with its reservation RZone105b that finishes as record, on the part of invisible Zone R territory (Invisible RZone) 106, also carry out record again, with it as invisible Zone R territory (Invisible RZone) 108, afterwards, send the order (the step S20 of Fig. 2) of the second reservation RZone105b of closed front from epigyny device 1.
So, the system controller 4 of optical disc apparatus 2 is accepted the order (the step S21 of Fig. 4 (B)) of the closed second reservation RZone105b from epigyny device 1, control light picker 9 by internal bus 8 and record reproducing circuit 5, read the interior up-to-date RMD information (the step S22 of Fig. 4 (B)) of RMA of record on R-Info.511 shown in Figure 9 or 521.
Then, after system controller 4 leaves the up-to-date RMD information of having read in the RMD posting field of having guaranteed in the data-carrier store 7, the closed second reservation RZone105b, thus become recordable white space and whether have (the step S23 of Fig. 4 (B)) according to exploring based on the table of the white space of the up-to-date RMD information in the above-mentioned RMD posting field.
Herein, system controller 4 is discerned the second white space 107a according to the table of white space and is had this point, also have, on the ground floor recording layer of invisible Zone R territory (Invisible RZone) 108, confirm the position that record finishes, have again, the ground floor recording layer of confirming reservation RZone105b all writes down this point that finishes, thereby judge that the second white space 107a is recordable this point, behind the closed second reservation RZone105b, record 0 data filling material (パ デ イ Application グ) (being invalid data) (step S24 of Fig. 4 (B)) on white space 107a.
Like this, shown in 107b among Fig. 3 (C), second white space just record finishes.In addition, in the whole Unrecorded occasions of ground floor recording layer of invisible Zone R territory (Invisible RZone) 106, the second white space 107a can not write down.
Then, system controller 4 is shown in Fig. 3 (C), the second white space 107a becomes 107b by the filling of 0 data, be white space no longer, thereby in the table of the white space in the RMD posting field of from data-carrier store 7, having guaranteed the deletion second white space 107a the beginning sector numbers and finish sector numbers, after its next beginning sector numbers and the information that finishes sector numbers promoted, the RMD after this renewal is recorded on the R-Info.511 or 521 of CD 3 (the step S25 of Fig. 4 (B)).
Fig. 6 (C) expression has been deleted the beginning sector numbers of the second white space 107a in a manner described and has been finished the table of the white space in RMD posting field sector numbers, that guaranteed in the data-carrier store 7.In addition, the beginning sector numbers that exists with occasion 205～208 that represented to be stored, that Fig. 3 (C) is not shown has produced at the 3rd, the 4th white space among this Fig. 6 (C), finish sector numbers.The occasion that does not produce at the 3rd, the 4th white space is 0.
In addition, not regularly to fill at this with 0 data, but can be in other data of later again time recording.In this occasion, in end of record (EOR) the moment upgrade RMD, from the white space table, delete.Also having, is not must be temporarily to write down other data on second white space whole, but can be only at the enterprising line item of a part.In this occasion, the zone except the part that has write down is registered in RMD again.Upgrade the beginning sector numbers like this or finish some in the sector numbers.
Also have, on the R-Info.511 or 521 of CD 3, write down after the RMD that has upgraded, suddenly this CD 3 is taken out from optical disc apparatus 2 sometimes.In this occasion, the management information RMD relevant with this CD 3 will lose in optical disc apparatus 2., once more this CD 3 optical disc apparatus 2 of packing into, the management information of record will be read out and write afterwards in data-carrier store 7 on the R-Info.511 of CD 3 or 521.
Carry out above-mentioned action repeatedly, last to the end of record (EOR) of the information signal of CD 3, send the closed or perfect order (the step S30 of Fig. 2) of carrying out the boundary from 1 pair of optical disc apparatus 2 of epigyny device.The system controller 4 of optical disc apparatus 2 is accepted the words of the closed first reservation Rzone, closed boundary (or carrying out perfect) order (the step S31 of Fig. 5) from epigyny device 1, just control light picker 9, read the interior up-to-date RMD information (the step S32 of Fig. 5) of RMA of record on R-Info.511 shown in Figure 9 or 521 by internal bus 8 and record reproducing circuit 5.
Then, after system controller 4 leaves the up-to-date RMD information of having read in the RMD posting field of having guaranteed in the data-carrier store 7, the closed first reservation RZone101a, thereby become recordable white space and whether exist according to exploring based on the table of the white space of the above-mentioned up-to-date RMD information in the above-mentioned RMD posting field, also have, whether the other parts blank region does not deposit (the step S33 of Fig. 5).
Herein, the first reservation RZone101a still is Unrecorded, thereby system controller 4 controlling recording playback circuitry 5 and light picker 9, with 0 data filling material (invalid data) reservation RZone101a record is finished (promptly, the closed first reservation RZone), as a result, the zone of the ground floor recording layer of the RZone101a that shown in Fig. 3 (C) first preengage all is recorded, and the first white space 103a just becomes recordable.
Herein, system controller 4 is by means of light picker 9, in closure after the first reservation RZone, record 0 data filling material on the first white space 103a.Occasion in that other white space exists just also writes down 0 data filling material (the step S34 of Fig. 5) on this zone.CD 3 just becomes the recording status shown in Fig. 3 (D) like this.Among Fig. 3 (D), 101b represents to write down the first reservation RZone that finishes with invalid data, and 103b represents to write down first white space that finishes with invalid data.Also have, the RZone of the information of wishing has been write down in 109 expressions.In addition, the outer circumferential side at the Rzone of Fig. 3 (D) has write down Boder-out (not shown).
Then, delete the beginning sector numbers of first white space the table of the white space in the RMD storage area of system controller 4 in data-carrier store 7 and finish the part that sector numbers is stored, promote the information of its next white space.Exist at other white space, to this regional record the occasion of 0 padding data (invalid data), just delete the beginning sector numbers in this zone and finish the part that sector numbers is stored, promote the information (more than be the step S35 of Fig. 5) of its next white space.
Like this, the upper of the table of the white space in data-carrier store 7 becomes 0 occasion, just be judged as and do not had white space, system controller 4 is just controlled light picker 9, the management information RMD of the table of the white space that has upgraded comprising in the data-carrier store 7 is recorded on the R-Info.511 or 521 of CD 3 (the step S36 of Fig. 5).
Like this, according to present embodiment, registration in the management information RMD of data-carrier store 7, upgrade the beginning sector numbers of white space and finish sector numbers, it is recorded on the zone of regulation of CD 3, thereby only read up-to-date RMD, just can know the having or not of white space, place.Therefore, need be when boundary not closed or when improving etc. explore white space again, can cut down the closure on boundary and improve the required time, can improve the convenience of optical disc apparatus.
Secondly, other embodiment of the present invention is described.This embodiment, for example shown in Figure 7, be the example of only on ground floor recording layer 501, having preengage RZone by the CD (for example DVD-R) of the Worm type of 2 layers of the single faces of ground floor recording layer 501 and second layer recording layer 502 laminations.Promptly, in Fig. 7, from the interior thoughtful peripheral direction of CD, be formed in order ground floor recording layer and second layer recording layer two sides go up reservation and the first reservation RZone301 that finishes at record on the part of ground floor recording layer, record finishes on ground floor recording layer and second layer recording layer two sides RZone302, only at reservation on the ground floor recording layer and the Unrecorded second reservation RZone304 with only on the part on the ground floor recording layer, write down the invisible Zone R territory (Invisible RZone) 306 that finishes.
Above-mentioned RZone301,302,304 and 306 is paid with Zone R territory sequence number respectively successively.Herein, RZone301,302, each Zone R territory sequence number of 304 and 306 are #10, #11, #12, #13.Also have, in each Zone R territory sequence number, it begins sector numbers, skip sector numbers and finish that known sector numbers is mapped as management information in the sector numbers, is recorded on the R-Info.511 or 521 of CD 3, and leaves in the data-carrier store 7 in the optical disc apparatus 2.
In addition, for the record RZone302 that finishes, the beginning sector numbers, skip sector numbers and finish sector numbers and know, the invisible RZone306 that finishes for part of records, beginning sector numbers and end sector numbers ESN ' know, but, for Unrecorded invisible Rzone, finish sector numbers and skip sector numbers uncertain.Also have, only the reservation RZone of ground floor recording layer does not exist and skips sector numbers.
For example, the finish beginning sector numbers of RZone302 of the record of above-mentioned Zone R territory sequence number # 11 is X, the sector numbers of skipping that expression record is transferred to the sector numbers of the ground floor recording layer before the second layer recording layer from the ground floor recording layer is Y, expression to the end of record (EOR) of this RZone the end sector numbers of sector numbers be ESN.In addition, on the CD that has adopted this embodiment, write down synchronizing signal in the dish fabrication phase with predetermined distance in advance, this synchronizing signal record position as benchmark, has been come record data with sector unit.
In Fig. 7, inwhole recording information signals on the ground floor recording layer of the first reservation RZone301, the first reservation RZone301 and and the RZone302 that finishes of the record of its outer circumferential side adjacency between second layer recording layer on have white space 303, also have, only second of the ground floor recording layer reservation RZone304 is Unrecorded, thereby clips reservation RZone304 and the record that formed finishes and also has white space 305 on the second layer recording layer between the invisible RZone306 that RZone302 and part of records finish in central authorities.
In the above-mentioned white space 303, the beginning sector numbers is according to record finish the beginning sector numbers X of RZone302 and definite X one thick stick, finishes sector numbers and be the finish end sector numbers ESN of RZone302 of record.Promptly, as having illustrated with Figure 10, it is narrower than the amplitude on the second layer recording layer 502 that the light beam 601 of laser sees through the amplitude of ground floor recording layer 501, the laser of position that has passed through the sector numbers X of ground floor recording layer 501 reaches the position this point of X one thick stick of second layer recording layer 502 to be known in advance, thereby can begin sequence number X one thick stick according to the sector that beginning sector numbers X calculates white space 303.Also Y one thick stick with definite according to skipping sector numbers Y is identical for this.
Equally, in the above-mentioned white space 305, the beginning sector numbers is to skip sector numbers Y and definite Y one thick stick according to what record finished RZone302, and finishing sector numbers is the end sector numbers ESN ' of invisible RZone306.
Herein, in the above-mentioned embodiment, in order to specify white space 303,305, in management information RMD, register, upgrade the beginning sector numbers of white space and finish sector numbers, but, as mentioned above, in each Zone R territory sequence number, the beginning sector numbers in its Zone R territory (RZone), skip sector numbers and finish that known sector numbers is mapped as management information in the sector numbers, be recorded on the R-Info.511 or 521 of CD 3, and leave in the data-carrier store 7 in the optical disc apparatus 2, also can be by registration, upgrade Zone R territory sequence number and specify white space 303,305.
For example by specifying Zone R territory sequence number # 10 and #11, just can be according to beginning sector numbers X and the end sector numbers ESN of Zone R territory sequence number # 11, on the second layer recording layer 502 between Zone R territory sequence number # 10 and the #11, to specify the beginning sector numbers be X one thick stick, finish sector numbers is that the white space 303 of ESN exists this point.
Also have,, just can specify the existence of white space 305 by specifying Zone R territory sequence number # 11#13.Promptly, the finish end sector numbers ESN ' of invisible RZone306 of the part of records of skipping sector numbers Y and Zone R territory sequence number # 13 of the RZone302 that finishes according to the record of Zone R territory sequence number # 11, just can be on the second layer recording layer 502 between Zone R territory sequence number # 11 and the #13, specifying the beginning sector numbers is that Y one thick stick, end sector numbers exist this point for the white space 305 that finishes sector numbers ESN '.
In addition, at the invisible RZone with the outer circumferential side adjacency of preengaging RZone304 is Unrecorded occasion, it is uncertain that this finishes sector numbers, but can distinguish that there is this point in the white space 305 of beginning sector numbers Y one thick stick on the second layer recording layer of the upside of preengaging RZone304.In this occasion, the end sector numbers of white space 305 is made as the value (for example 0) of regulation in advance, part or all identifying recording layer at invisible RZone306, like this, after end sector numbers ESN ' determines, the end sector numbers of white space 305 is updated to ESN ', so also is fine.
According to present embodiment, registration among the management information RMD in data-carrier store, upgrade the white space that determines according to Zone R territory sequence number begin sector numbers at least, it is recorded in the regulation zone of CD, thereby only reads up-to-date RMD, just can know the having or not of white space, place.Therefore, need be when boundary not closed or when improving etc. explore white space again, can cut down the closure on boundary and improve the needed time, can improve the convenience of optical disc apparatus.
In addition, in the above-mentioned embodiment,, narrated the example of the DVD-R of Worm type, but, the invention is not restricted to this, but can be equally applicable to the rewriting of the same area is returned the CD of the conditional rewriting type of number as CD with 2 layers of recording layer of single face.Example as the CD of this rewriting type has DVD-RW.
In the occasion of the DVD-RW with 2 layers of recording layer of single face, on the new product dish, ground floor, the second layer all are Unrecorded.Therefore, the occasion that on new product DVD-RW, writes down at first, identical with the occasion of the DVD-R of 2 layers of the single faces of having narrated before this, when record, can produce white space sometimes.Therefore, identical with the occasion of DVD-R, the present invention also goes for DVD-RW.On the other hand, when rewriting write down regional, can not produce white space as described above again.
