Embodiment
Below with reference to accompanying drawing the overlapping recording method of once recordable compact disk of the present invention and the embodiment of device are described in detail.
Adapt therewith, though the most widely used general term now selected in the term that uses among the present invention, but the term of under specific situation, also selecting with copywriter self, in this case, can write down its detailed meanings in the declaratives of corresponding invention, so be not the term of simple term name, need to be grasped the present invention and further illustrate.
Fig. 2 is the method synoptic diagram according to overlapping record in the once recordable compact disk of the present invention.
Same as shown in Figure 2, divide into Lead-In Area (Lead-inZone), data field (Data Zone) and leading-out zone (Lead-out Zone) in the Blu-ray Disc of once recordable (BD-WO).Be assigned interior spare area (ISA:Inner Spare Area), outer spare area (OSA:Outer SpareArea) in the front-end and back-end of data field.
Therewith in the once recordable compact disk of identical formation, necessity during records management information is used according to CD can repeatedly be upgraded, so as the zone that in CD, is used to write down the disc management information that can repeatedly upgrade, temporary defect management area territory (TDMA:Temporary Defect Management Area is designated hereinafter simply as ' TDMA ') is provided in the Lead-In Area (Lead-in Zone).
Record temporary defect table (TDFL:Temporary Defect List in TDMA, be designated hereinafter simply as ' TDFL '), include defect map (List of Defects) in described TDFL, it is several DFL clauses and subclauses (the Defect List entry) formation by the management information that records actual defects district or overlapping recording areas positional information etc.(back will be elaborated to this)
Therewith in the once recordable compact disk that same discrimination is distributed, in the data area, exist when having finished the zone (Previously Recorded Area) of record, respective regions does not allow overlapping record (Overwrite) as the once recordable compact disk physical characteristics.
But, record order such as user or main frame is same as shown in Figure 2, when requirement is write down in a-b zone (zone finished in record), in the present invention, carry out optical record-play device self that video disc recording plays its replacement is recorded in other zone in the data area.
Thus, whether user or main frame are finished specific region record in the CD can have no to assign record order relatedly, and this also can be used as re-recordable optical disc in once recordable compact disk.Physical overlap record alpha region to this and re-recordable optical disc is called the overlapping record of logic (LOW:Logical Overwrite).
Promptly, same as shown in Figure 2, for the record order of carrying out the a-b zone, described zone is because be the zone of having finished record from physically saying, so can't be to the overlapping once more record in this zone, but (Data Zone) can replace being recorded to and not have the c-d of record data zone in the data area.As an alternative Ji Lu zone can be the user data area (User Data Area) that do not have record data or spare area (ISA, OSA).
Behind identical alternative record therewith, be recorded as TDFL information with replacing among the TDMA of information in CD of posting field, finish record order.
For the CD of similarly finishing record, according to user's requirement, when main frame required the a-b zone to play, optical record-play device replaced the broadcast in a-b zone with reference to TDFL information, plays the c-d zone, finishes play command thus afterwards.
On the other hand, similar therewith, exist in the CD of once recordable under defect area (Defect area) situation, the data that be recorded in defect area replace being recorded in spare area, and (ISA, OSA), this method is illustrated with reference to Fig. 3.
Fig. 3 is the method synoptic diagram according to management of defective areas in the CD of once recordable of the present invention.
Same as shown in Figure 3, differentiation is assigned Lead-In Area (Lead-in Zone), in the once recordable compact disk of data field (Data Zone) and leading-out zone (Lead-out Zone), defectiveness zone (a-b) can take place in the inner specific region, data area (Data Zone) of record real data.
Described defect area physically says and can occur in one bunch (Cluster) or one with in putting on an arrow, and Fig. 3 situation is exactly that several in (Consecutive) bunch defective situation take place continuously.
Similarly, take place under the situation of defective in several successive clusters, by the setting (setting) on the CD drive (driver), even in tackling one bunch defective takes place, defect cluster periphery several bunches while also may take place as defect area disposition in addition in bunch situation that also may damage or pollute around.
With mutually identical, in when, in the data area (Data Zone) defect area (a-b) taking place, the data that are recorded in defect area (a-b) replace being recorded in spare area, and (ISA, OSA), the situation of Fig. 3 is exactly to be recorded as example with the c-d zone replacement of spare area (OSA) outside to be illustrated.
Identical with the above, replace record outside in the spare area (OSA), Xiang Guan management information by TDFL information record, is finished the execution of record order in TDMA therewith.
Thus, for this CD of finishing record, the main frame that requires according to the user will carry out a-b zone when playing afterwards, and optical record-play device replaces the a-b zone to play and play c-d with reference to the management information that has write down playing, carry out play command.
According to the present invention, substitute the defective that takes place in several successive clusters (consecutivemultiple Cluster) of record in spare area (spare area) and be called CRD (Consecutive Real locatableDefect: reality can be located defective continuously) especially.
Relevant therewith is, replaces being recorded in the defective that takes place in bunch of spare area and is called RAD (Reallocatable Defect: reality can be located defective).For the defective that takes place in bunch, also exist the spare area not substitute situation about writing down in addition, this is called NRD (Non-Real locatable Defect: non-reality can be located defective).
With identical shown in the embodiment of Fig. 2 and Fig. 3, the overlapping recording method of logic of the present invention is replacing overlapping posting field data to be recorded in the spare area, when the continuous defect zone takes place, the data that are recorded in defect area are replaced being recorded in identical processing of CRD type of spare area.
Thus, in the overlapping recording mode of logic, the form that is recorded in the DFL clauses and subclauses is used the CRD entry type, and this is illustrated with reference to institute's accompanying drawing.
Fig. 4 is the method synoptic diagram according to the overlapping records management information of record in the CD of once recordable of the present invention.
Same as shown in Figure 4, overlapping when being recorded in write down regional according to overlapping record (overwrite) order according to the main frame of customer requirements etc., replace record with noted earlier identical by spare area etc.
This situation, the identical processing of replacement (CRD) type of necessary overlapping records management information and continuous defect bunch.
Promptly, replacement (CRD) type (type) for continuous defect bunch, the management information that is recorded in TDMA can use two DFL clauses and subclauses to represent, same as shown in Figure 4, for clauses and subclauses, the relevant information whether the information record by each DFL entry type (type) in " state 1 (status 1) " field replaces record (for example, if ' 0000 ', defect area is represented normal RAD (Re-allocation Defective) type that record finishes or the DFL clauses and subclauses of CRD (Consecutive Re-allocation Defect) of replacing, though if for ' 0001 ' be defect area, the DFL clauses and subclauses of replacement area NRD (Non-Real locatableDefect) type of replacing record are specified in expression).In " defect cluster the 1st physical sector number (Defective Cluster firstPSN) " field record take place defective bunch positional information, at this moment, said positional information is recorded as first physical sector number of respective cluster (PSN:physical sector number) above.
In addition, in " status 2 " field, (for example together write down each DFL entry type (type) and attribute information with described " status 1 " field, under ' 0000 ' situation, the situation of defective takes place in representing one bunch, and ' 0001 ' situation represents the beginning (start) of a consecutive numbers defect cluster, when ' 0010 ' time, expression is last (end) of several defect clusters continuously).The recording defect zone substitutes the zone position information that is recorded in the spare area in " replacement bunch the 1st physical sector number (Replacement Cluster first PSN) " field, and at this moment, positional information is recorded as first physical sector number of respective cluster (PSN).
In addition, use another clauses and subclauses in " state (status) 1 " and " state (status) 2 " field, show each DFL entry type (type) information (particularly in " status 2 " of second clauses and subclauses field, record continuous several defect clusters of announcement and replacement cluster end (end) ' 0010 ' bit), in " DefectiveCluster first PSN " field, record in the positional information that defect cluster takes place last bunch first physical sector number (PSN), in " Replacement Cluster first PSN " field, record defect area and replace being recorded in the zone position information in the spare area first physical sector number (PSN) of last bunch.
At this moment, clauses and subclauses are made of 8 bytes (64 bit).For " status " field is distributed 4 bits respectively, be " Defective Cluster first PSN " that " Replacement Cluster first PSN " field is respectively distributed 28 bits.
Use has the entry format of the present invention of same configuration therewith, embody the illustrational words of Fig. 4 of overlapping recording method, record in first clauses and subclauses (DFL entry 1) " status 1 " field expression replace record ' 0000 ', in " Defective Cluster first PSN " field, record the first physical sector number ' a ' of defect cluster.
In addition, record in " status 2 " field expression continuous defect bunch beginning ' 0001 ', in " Replacement Cluster first PSN " field, record defect area and replace the first physical sector number ' c ' in position that is recorded in the spare area.
In addition, record in second clauses and subclauses (DFL entry 2) " status 1 " field expression replace record ' 0000 ', in " Defective Cluster first PSN " field, record first physical sector number ' b ' of last bunch of defect cluster, record in " status 2 " field expression continuous defect bunch end ' 0010 ', replace last bunch the first physical sector number ' d that is recorded to position in the spare area and in " Replacement Cluster first PSN " field, record defect area.
Thus, afterwards,, when main frame (host) etc. requires the a-b zone to play,, only move the c-d zone and play just passable with reference to the information that writes down in the TDMA zone according to user's requirement.
On the other hand, identical therewith, for the method for using the relevant management information of two overlapping records of (DFL entry 1, DFL entry 2) expression of DFL clauses and subclauses, the order of described two clauses and subclauses general names is the CRD clauses and subclauses.
Fig. 5 is when having had defect area in the posting field in the once recordable compact disk of the present invention, the method synoptic diagram of overlapping record.
The CD of (a) among Fig. 5 expression is the area schematic that has write down in the once recordable compact disk, and identical with (a) among Fig. 5, the posting field of described CD has defect area.
The management information relevant with defect area is recorded in TDMA zone (not shown) in the CD, and during in particular for the RAD type, the data replacement that is recorded in described defect area is recorded in the spare area.
So, when comprising in the posting field of defect area, not limited to by described defect area, in CD, replace to be recorded in and replace in the zone according to the overlapping record of Host Command.
That is, whether to replace record irrelevant with the data that write down in the related administrative information of described defect area and the described defect area, carries out the overlapping record of logic in the replacement area on CD.This just on the once recordable compact disk characteristic in the posting field because can't record data and be not subjected to the reason of defect area limitation.
Thus, identical with (b) among Fig. 5, after the overlapping record of the logic in a-b zone finished, write down in the expression CD TDMA zone the seventh day of lunar month a defect area relevant information 7 DFL clauses and subclauses in, the relevant information that comprises overlapping posting field a-b zone is recorded as 6 DFL clauses and subclauses.(a CRD table of articles is shown two DFL clauses and subclauses)
Fig. 6 is the method synoptic diagram of overlapping record when having defect area according to the zone of replacing record in the CD of once recordable of the present invention.
Same as shown in Figure 6, the zone (Previously recorded area) that record has been finished in existence in the user data area on the CD (User data area), in the time of will carrying out overlapping record for the a-d zone in the described zone of having write down, can write down with noted earlier identical for the e-h zone that does not have record data on the CD.
At this moment, in the e-h zone of described replacement record defect area (Xm) may take place.In this case, optical recorder is according to defect management method, with the data of record in the defect area (Xm) replace be recorded in the optical disk standby area territory (ISA, OSA).
After the phase negative lap record, the regional relevant information of described replacement record should be recorded in the DFL clauses and subclauses, can infer following method according to the present invention therewith.
Promptly, the overlapping posting field a-d of described logic zone relevant information, with the eh zone relevant information that replaces record with the CRD entry record after, record data are replaced the method that the relevant information in the zone of writing down is write down with the RAD clauses and subclauses in defect area (Xm) that takes place in the zone of described replacement record and the described defect area.
But this method reads the a-b zone for reading a-b area light recording and reproducing apparatus afterwards, and the less important again problem that reads the replacement zone of described defect area takes place.So this is because the DFL clauses and subclauses are made the processing speed that has influence on optical record-play device repeatedly.
Thus,, when replacing posting field generation defect area during the overlapping record of logic, use each corresponding CRD clauses and subclauses respectively of DFL entry record, be recorded as the CRD clauses and subclauses of non-overlapping copies and the method for RAD clauses and subclauses according to the present invention.
For this reason, same as shown in Figure 6, write down (Xm) and be considered as defect area with replacing the corresponding position of the defect area (Xm) that takes place among the regional e-h, separate the described zone that defect area and the overlapping record of logic carry out that is considered as respectively, by the data playback journal to the DFL clauses and subclauses.
Thus, for Fig. 6 situation, be recorded as three DFL clauses and subclauses altogether, the information that the data that write down in the a-b zone of having write down at first replace being recorded in the e-f zone is recorded in the CRD clauses and subclauses 1.
In the CRD clauses and subclauses 1 with noted earlier identical, be recorded as in " Status 1 " field of first DFL clauses and subclauses ' 0000 ', be recorded as ' a ' in " Defective Cluster first PSN " field, be recorded as in " Status 2 " field ' 0001 ', be recorded as ' e ' in " Replacement Cluster first PSN " field.In addition, be recorded as in " Status 1 " field of second DFL clauses and subclauses ' 0000 ', first physical sector number ' b ' of record respective cluster in " Defective Cluster first PSN " field, record ' 0010 in " Status 2 " field ', and first physical sector number ' f ' of record respective cluster in " Replacement Cluster first PSN " field.
In addition, be considered as the zone (Xm) of defect area on the posting field so be recorded as the RAD entry type because defective takes place in one bunch, in " Status 1 " field, be recorded as ' 0000 ', in " Defective Clusterfirst PSN " field be ' b ', in " Status 2 " field, be recorded as ' 0000 ', in " ReplacementCluster first PSN " field, be recorded as ' i '.
In addition, the data that will write down in the c-d zone are replaced the information that is recorded in the g-h zone and are recorded in the CRD clauses and subclauses 2, be recorded as in " Status 1 " field of first DFL clauses and subclauses ' 0000 ', be recorded as ' c ' in " Defective Cluster firstPSN " field, be recorded as in " Status 2 " field ' 0001 ', and in " ReplacementClustef first PSN " field, be recorded as ' g '.In addition, be recorded as in " Status 1 " field of second DFL clauses and subclauses ' 0000 ', be recorded as first physical sector number ' d ' of respective cluster in " Defective Cluster first PSN " field, and be recorded as in " Status 2 " field ' 0010 ', be recorded as the first physical sector number ' h ' of respective cluster in " Replacement Cluster firstPSN " field.
Thus, optical record-play device will be play when a-d is regional on the CD afterwards, by the DFL items for information of described record, directly carries out the broadcast in corresponding replacement zone (e-f, i zone, g-h zone), improves the broadcast performance of optical record-play device.
Identical with described explanation, if when replacing in the once recordable compact disk having defect area in the zone of record, the method for overlapping record is illustrated with reference to the schedule work of accompanying drawing 7.
S10, same as shown in Figure 7, at first according to user's requirement, in main frame, assign the record order of the posting field of once recordable compact disk.
S20, optical record-play device carries out in logic overlapping record according to record order to replacement area on the CD.
S30 at this moment, judges to replace posting field whether to have defect area.
S40 when if there is defect area in the zone of described alternative record, according to defect management method, replaces being recorded to spare area (ISA, OSA) with the data that will write down in the defect area.
S50, after, be considered as defect area with the corresponding position of generation defect area posting field in the zone that replaces writing down, separate being considered as defect area and the overlapping record of logic operation area respectively, be recorded to the DFL clauses and subclauses in order.
S60 replaces described in the above-mentioned S30 when not having defect area in the posting field, and the regional record of the overlapping record of logic is the DFL clauses and subclauses, and the words that the overlapping record of logic is finished get final product.
On the other hand, during the overlapping record of logic, replace replace record in the zone before, detect to replace in the zone whether have defect area in advance, the data that be recorded in defect area replace being recorded to the embodiment of spare area etc. because be the change in defective area detection stage only.
Relevant therewith, when detecting defect area before the identical therewith replacement record, zone except that described defect area replaces record, also can be recorded as and not finish the clauses and subclauses that defect area replaces NRD (Non-Reallocatable Defect) type of record.
Accompanying drawing 8 is according to described enforcement example of the present invention, realizes the formation piece figure of the optical record-play device of the technology of the present invention thought.
Same as shown in Figure 8, the optical record-play device formation comprises: be used for the recording and reproducing apparatus (recording/reproducing device) 10 of recording played on CD 1, and main frame or control device (Host or Controller) (hereinafter to be referred as the main frame) 20 of controlling it.
Constitute identical optical record-play device therewith and say basically, control device 20 transmits the record or the play command of specific region to recording and reproducing apparatus, and described recording and reproducing apparatus 10 writes down and plays specific region on the CD 1 according to the order of main frame 20.
At this moment, specifically described recording and reproducing apparatus 10 constitutes and comprises: carry out the interface (Interface) 12 that data command reception etc. is communicated by letter with main frame 20; Direct light picker 11 to video disc recording data or broadcast; The signal restoring that to read from light picker 11 is the signal numerical value that requires, and perhaps the signal demodulation (modulation) with record is signal that is recorded to CD and the data processor 13 that is transmitted; For from CD, correctly reading signal or, controlling the servomechanism installation 14 of light picker 11 to the correct tracer signal of CD; Several signals and the data memory storing 15 in a period of time that comprise management information; The microprocessor 16 of taking on inscape control task in the recording and reproducing apparatus 10.
Constitute therewith in the identical optical record-play device of the present invention, the recording process of once recordable compact disk is described as follows.
At first, once recordable compact disk inserts in the optical record-play device, reads all management information in the CD, and is stored in the storer 15 in the recording and reproducing apparatus 10, and these management information are used when video disc recording is play.
In this state, when customer requirements write down in the CD specific region, main frame 20 as record order, required the data of positional information to be sent to recording and reproducing apparatus 10 with record this.
At this moment, after the microprocessor 16 receiving record orders in the described recording and reproducing apparatus 10, from the management information that is stored in storer 15, judging that main frame 20 requires whether the zone in the CD of record is that defect area is still finished posting field, is not that defect area or record finish that the record order by main frame 20 carries out record in the zone in zone.
Therewith in the identical recordings process or afterwards, in the time of should carrying out overlapping record (Overwrite) according to the order of main frame 20, the data that are recorded to the overlapping region as in the data area not posting field replace record, the regional relevant information of described replacement record as the DFL entry record to the TDMA zone.
At this moment, in the described replacement posting field as have a defective, with defect area accordingly posting field see defect area as, separate being considered as defect area and the overlapping record of logic operation area respectively, be recorded to the DFL clauses and subclauses in order.
At this moment, microprocessor 16 will replace the positional information of posting field and data to be sent to servomechanism 14 and data-processor 13 in the optical record-play device 10, require to finish in the position record or replace record in CD by light picker 11.
Ji Lu once recordable compact disk by this method, player method according to the present invention is explained as follows.
At first, what record data can be once, and recording disk inserts recording and reproducing apparatus, reads all management information in the CD, is stored to the storer 15 in the recording and reproducing apparatus 10, and these management information are used when video disc recording is play.
In this state, when play customer requirements CD specific region, main frame with this as play command, the information that requires to play is sent to recording and reproducing apparatus 10, microprocessor 16 in the described recording and reproducing apparatus 10 is after receiving play command, in the management information from be stored in storer 15, judge whether the CD inner region that main frame 20 requires to play is replaced record as other zone in the data area, judge the position of defect area when not replacing record, this can confirm as the DFL clauses and subclauses etc. of TDFL in the TDMA zone that illustrates previously.
Thus,, play respective regions, broadcast information is sent to main frame 20 if the zone that described microprocessor 16 main frames 20 require to play does not replace record.If replacing record (ex.RAD/CRD type) is other zone, with reference to described DFTL items for information, play the zone of corresponding replacement record, be sent to main frame 20.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the scope of claims of the present invention variation, the modification of the above embodiment.
