Fig. 1 explanation is the zone of the PAC on the high density compact disc according to the present invention.With reference to figure 1, to the cylindrical circumference ingress area, a data field and a derivation zone are divided and be appointed as to high density compact disc from the circumference of inboard.Front-end and back-end in the data field possibly have inner spare area (hereinafter to be referred as " ISA ") and outside spare area (hereinafter to be referred as " OSA ") respectively.When breaking down the zone in the data field, spare area ISA and OSA are the zones that reconfigures that is used for being write the data on the fault zone.INFO2 zone and the INFO1 zone that is used for writing down various types of information above that divided and be appointed as to ingress area.INFO2 zone and INFO1 zone have physics access control (PAC) zone respectively.
For the sake of simplicity, the PAC zone of distributing to the INFO2 zone is called as the PAC2 zone, is called as the PAC1 zone and distribute to the regional PAC zone of INFO1.One of PAC2 zone and PAC1 zone have the original PAC of record above that, and another is the back-up zone, is used to write down the back-up of original PAC.Direction in view of the circumference from the inboard of disk writes to the cylindrical circumference preferably is recorded in original PAC on the PAC2 zone, is recorded on the PAC1 zone and back up PAC.The PAC zone that is provided is used to deal with problems, and this problem is easy to drive to fail to detect to drive from redaction at early version take place when adding the function on the disk to, and it has one " unknown rule ".
Should " unknown rule " have the rule that is used to control the predictable operation of disk of definition above that, that is, control from read basically, write, or the like control begin to the fault zone once replacement, logical overwrite, or the like.Therefore, in the processing of back, will describe in more detail, and a zone will be provided being suitable on the disk of " unknown rule ", it has and is used to define whole disks, perhaps the fragment of certain a part of disk.
Thereby through utilizing " unknown rule " definition early version to drive the zone of access, the redaction CD has reduced early version and has driven unnecessary accessing operation.
In addition; But through using PAC on the disk physical region, to drive the definition accessing zone so that carry out access as early version, having the data area of having write down user data above that can be protected more con vigore, and from the outside inappropriate visit of disk; Such as usurping, can be prevented from.Simultaneously, consider the write characteristic of high density compact disc, with INFO2 zone and the INFO1 zone that has PAC2 and PAC1 zone in the ingress area is discussed.
Fig. 2 explanation structure that INFO2 is regional and INFO1 is regional on the high density compact disc according to the present invention.With reference to figure 2; BD-RE, the INFO2 zone of supposing high density compact disc have 256 bunches; Comprise 32 bunches of PAC2 zones; 2 zones, 32 bunches of fault management zones (DMA) are used for managing failures, have 32 bunches of control datas (CD), 2 zones of record control information above that, and 32 bunches of buffer zones (BZ), 3 zones of buffer zone.The INFO1 zone comprises the BZ2 zone of 32 bunches of buffer zones; 32 bunches of drive areas; It is to be used to store a drive area of specifying the concrete information that drives; 32 bunches of DMA1 zones are used for managing failures, and 32 bunches of CD1 zones are used for record controls information, and the BZ1-PACI zone is used for using as the PAC zone.
High density compact disc (BD-R), the INFO2 zone of supposing writable disposable have 256 bunches; It comprises PAC2 zone, DMA2 zone, CD2 zone and BZ3 zone; Wherein each has 32 bunches; And the INFO1 zone comprises BZ2 zone, DMA1 zone, CD1 zone and BZ1-PACI zone, and wherein each has 32 bunches of with the drive area 128 bunches.Therefore, according to the rewritten characteristic of high density compact disc, PAC of the present invention zone is assigned to INFO2 zone and INFO1 zone in the ingress area respectively through 32 bunches.In 32 bunches of PAC zones, a PAC has one bunch.The structure of a PAC who is recorded in a bunch of size will be described with reference to figure 3.
Fig. 3 has explained the structure that is recorded in the PAC on the high density compact disc according to the present invention.A PAC with reference to 3, one bunches of sizes of figure (32 sector) comprises a head zone, and an information zone specific that is assigned to disc drives.The PAC head zone has 384 bytes of first sector of distributing to PAC; Be used to write down various types of PAC information; Such as " unknown PAC rule " and the information on fragment and other zones in PAC zone, this PAC zone has the customizing messages that the appointment disc drives that writes down is known as " known rule " above that.
The concrete structure that is recorded in the PAC in the said structure will be described with reference to accompanying drawing 4.For simplicity, in instructions of the present invention, will need the specific fields of PAC in greater detail with reference to the description of drawings of description field.Fig. 4 explains according to the present invention the structure of PAC on the high density compact disc.With reference to figure 4, as stated, PAC comprises the head that is applicable to all PAC, and the zone with customizing messages of the driving that appointment writes down above that.
On the contrary, head part comprises " whole dish mark ", " fragment number " and 32 fragments " fragment _ 0～fragment _ 31 " that each has 8 bytes of 1 byte of 4 bytes " PAC_ID ", 4 bytes " unknown PAC rule ", 1 byte." PAC_ID " is the field that is used to provide existing PAC state and authentication code; If wherein " PAC_ID " has ' 00 00 00 00 ' bit; Then the existing PAC of " PAC_ID " sign is not used; " if PAC_ID " have ' FF FF FF FE ' bit, then " PAC_ID " sign existing PAC zone is because failure and other reasons is out of use, and if " PAC_ID " have ' FF FF FF FF ' bit; Even then the PAC zone was used in the past, the existing PAC zone of " PAC_ID " sign can be used again.In addition, if disk is existing driving can free access one, then through record " PAC_ID " in the position of agreeing in advance, such as " 54 53 54 00 " bit, " PAC_ID " is used as the code that is used to confirm.More particularly; If existing the driving do not known applied " PAC_ID "; When owing to reasons such as version errors, when not knowing to have PAC now, existing driving confirms this situation, therefore ' 5,453 54 00 ' position is used as the code of the information of requirement reference record on " unknown PAC rule " field.As stated, " unknown PAC rule " field is used as the field that appointment can not be understood the opereating specification of the driving that has PAC now, will describe with reference to figure 5.
The configuration of Fig. 5 explanation " unknown PAC rule " field according to the present invention.With reference to figure 5, can be by controllable various zones on " unknown PAC rule " definition disk.Controllable areas on " zone " expression disk in the table, " control " expression control types, such as read/write or the like, and the required figure place of " figure place " expression control.Additional bit in " figure place " representes to have the situation of the dual layer disc of two recording/reproducing faces.For example, the read/write in PAC zone is controlled can be represented by " PAC zone 1,2 " field, and the fault management zone write controlled can the expression by " DMA zone 1,2 " field.Be used for the fault zone replacement zone write controlled can the expression by one " replacement cluster " field, the read/write of data field is controlled can be represented by one " data field " field, can be represented by one " logical overwrite " field and logical overwrite is controlled.
Significantly, writing controlled only is physically to be applied to rewrite disk BD-RE, and BD-R, and, be used for the writing controlled also being applicable to and can rewrite disk BD-RE of replacement zone of fault zone and BD-R in addition.Therefore, it will be appreciated that theme of the present invention depends on the rewritten characteristic of high density compact disc.Through using above-mentioned method, " unknown PAC rule " field allows for and drives version and do not match and on disk, specify zone of control.In addition, said method not only is applied to drive version and does not match, and is applicable to the access control in the physical zone that the user selects on the disk.
Simultaneously, " whole magnetic disk mark " field among Fig. 4 is used as and is used to notify PAC to may be used on the field of the Zone Full of disk, and " fragment number " field of the quantity of the segment area of expression PAC also is applicable to the Zone Full of disk.
Can be at most that PAC distributes 32 fragments, and the information on the fragment that is disposed be write each " Segment_0 " with 8 bytes and is arrived on the field of " Segment_31 ".Each " Segment_0～Segment_31 " field has above that first PSN and the PSN at end of segment area of the configuration of record.
With reference to accompanying drawing fragment will be described in more detail.Fig. 6 explanation is the segment area on the high density compact disc according to the present invention.With reference to figure 6, if desired, on high density compact disc of the present invention, 32 segment area can be arranged at most, be used for beginning Using P AC in order from " fragment 0 ".In this case, through on " fragment " field in PAC2 and PAC1 zone, writing first PSN of the regional starting position of indication allocated segments and indicating the last PSN of the end position in allocated segments zone, disc drives identifies the position of segment area.Be not that a plurality of allocated segments are overlapping, and bunch the border specify beginning and end position.When the fault zone is present in the segment area of configuration, in other words, suppose the high density compact disc BD-RE that can write, perhaps WO, the data that will be recorded on the fault zone are recorded on the replacement zone, such as the spare area.In the present invention, the replacement zone also is defined as the zone that belongs to segment area, and it will be described with reference to accompanying drawing.
Fig. 7 explanation shows the chart of the PAC method of high density compact disc according to the present invention.With reference to figure 7; For having the segment area that is applied to PAC of the present invention; If " A " appears in the segment area in the fault zone; The data that are written to fault zone " A " are written on spare area ISA or the OSA replaces, and the information of relevant replacement is written to as on the zone of the fault management in the ingress area of fault catalogue (DFL) inlet (DMA).The DFL inlet comprises " state 1 " and " state 2 " field; Be used to write down the information of relevant DFL inlet type; One " PSN of failed cluster " field is used for first physical sector number of record trouble bunch, and " replacement cluster the one PSN " is used to write down first physical sector number of replacement cluster.
Should " state 1 " field have one ' 0000 ' that writes down above that; Being used to indicate the fault zone is RAD (heavy distribution malfunctions) type, and wherein the fault zone should " failed cluster the one PSN " field be had a ' by replacement normally; First PSN in record trouble zone above that; " state 2 " field has above that ' 0000 ' of record, the situation that is used for indicating " state 2 " field to be not used in the high density compact disc that can write (if the high density compact disc of writable disposable, then this is used to indicate that to have bunch of fault); And " replacement cluster the one PSN " field has above that ' b ' of record, and it is first physical sector number in replacement zone.In this case; Because in the high density compact disc of writable disposable (WO) only once physics write; So hope to be written in the temporary disc management area (TDMA) that data in the fault zone at first are recorded in the disk that separates from the DMA zone; As having the temporary transient fault catalogue (TDFL) of a spline structure that enters the mouth, and when the user needs, perhaps, disk is written in the DMA zone after will accomplishing the time that writes as DFL with DFL.In the present invention, through using the DPL inlet, replace zone ' B ', the data that wherein will be written in fault zone ' A ' are replaced and are written to wherein, are called as replacement zone ' B ', belong to the affiliated fragment of fault zone A '.Because this method allow to exempt is used replacement zone ' B ' needs as isolated fragment, prevented that numerical limitations from being the waste of 32 segment area, and can use PAC to carry out effective fragment management.Therefore; Though describe the preferred embodiments of the present invention as an example through using the RAD type; Wherein in one bunch, carry out the replacement of fault zone, it is obvious that, under the situation that reconfigures fault (CRD) type continuously; The fault zone that wherein in a plurality of successive clusters, occurs is replaced, with the fault zone under the consistent mode of segment area come managing failures zone.
Simultaneously, with reference to figure 7, to write down the PAC that derives in the zone, the PAC copy of original PAC in order strengthening protecting PAC, and to be recorded in the INFO zone of deriving the zone.As stated, have first PSN and last PSN through the positional information of using the segment entry to be recorded on the segment area on " segment " field, wherein each has 32.Under this situation; Will describe with reference to figure 8; Consider that physical record unit on the CD is bunch, perhaps the positional information that is recorded in the segment area on " fragment " field represent without first PSN and last PSN, but by bunch physical sector number represent.
Fig. 8 explanation is used for the method for recorded segment positional information on high density compact disc according to the present invention.With reference to figure 8, for a plurality of segment area through the PAC management, the fragment inlet with positional information of each segment area comprises " PSN of first bunch in the fragment " field and " PSN of last bunch in the fragment " field.More particularly, as stated,, utilize first physical sector number and first physical sector number of last bunch of fragment of first bunch of fragment, the position of expression segment area in bunch unit because CD is written as a bunch unit.Consider the firmware that is used for driving operations, this method is suitable.
The block diagram of Fig. 9 explanation optical recording and/or reproducing device according to the present invention.With reference to figure 9, optical recording and/or reproducing device comprise a record/playback device 10, are used to carry out the recording/reproducing on the CD, and a main frame or controller 20, are used to control this record/playback device 10.(here, record/playback device 10 often is called one " disc drives ", and two terms all will be used for instructions of the present invention).
More particularly; Main frame 20 provides one and writes or reproduce order; So that the specific region that the specific region of CD is write record/playback device 10 or reproduced CDs from record/playback device 10, and record/playback device 10 responses from the command execution of main frame 20 to the record of specific region/from the playback of specific region.
Record/playback device 10 comprises an interface unit 12, is used to carry out and the communicating by letter of main frame 20, such as the exchange of data and order; One pick-up unit 11 is used for write direct CD/from the direct reading of data of CD of data, a data processor 13; Be used for receiving signal, and recover an expectation signal value, perhaps will be written into signal and be adjusted into the signal that to be write on the CD one from pick-up unit 11; And pass on, a servomechanism installation 14 is used for controlling pick-up unit 11 and accurately reads signal from CD; Perhaps write signal on CD accurately, a storer 15 is used for different types of information that temporary transient storage comprises management information and data; And a microprocessor 16, be used for the different piece of controlling recording/reproducing device 10.
To describe a method now, it is used for through utilizing optical recording and/or reproducing device on high density writable optical disc, to write down PAC.When CD was inserted into optical recording and/or reproducing device, all management information was read from CD and is saved in the storer of record/playback device 10, so that can when the recording/reproducing of CD, use.Here, if the user hopes on the specific region of CD, to write, then main frame 20 is regarded such customer requirements as write order, to record/playback device 10 information on the desirable writing position is provided, and one group of data that will be written into.
