Optical head 17 will perhaps will be exported to A/D-D/A conversion fraction 16 from the signal that CD media 3 is read from the signal record of A/D-D/A conversion fraction 16 in CD media 3.
The rotation of motor controller 13 control CD media 3.Under the situation of CLV (constant linear velocity), motor controller 13 makes linear velocity become constant according to the revolution of optical head position control motor 14 diametrically.
As shown in Figure 4, RAM12 be divided into recording status control data storer 121, write memory buffer 122, read memory buffer 123, program execution memory 124, placeholder record state control data storer 125 and working storage 126.In addition, RAM12 is also as the temporary transient data-carrier store of the required data of optical disc recording apparatus 2.
The recording status control data that CPU11 will be recorded in the data in the CD media 3 is recorded in the recording status control data storer 121.The Write-once optical disc medium is being carried out under the situation of recording operation, CPU11 is stored in the recording status control data of record data in the recording status control data storer 121 of RAM12.When data recording operation finished, the storage data in the CPU11 recording status control data storer 121 were recorded in the control data recording areas of CD media 3, to upgrade the user mode of CD media 3.Be recorded in state-of-the-art record state control data in the CD media 3 and represent all records of CD media 3.The write command illustration record order of recording status control data.The sync buffering order and finished track order illustration data recording stop order.In optical disc recording apparatus 2 of the present invention, in recording status control data storer 121, provide variable setting so that the management record data district in the management data district is provided with.
Writing memory buffer 122 is that temporary transient storage will record the memory of data in the CD media 3.In optical disc recording apparatus 2, the zone of the approximate 1M byte among the RAM12 has been assigned to writes memory buffer 122.When host apparatus 1 was write (10) order optical disc recording apparatus 2 director datas are write down by use, CPU11 was stored in record data and writes in the memory buffer 122 and be that CD media 3 is exported to record data in the unit by part 15, A/D-D/A conversion fraction 16 and optical head 17 with the data volume.A kind of like this recording method is used in the optical disc recording apparatus 2 usually.Therefore, even under host apparatus 1 has been through with the situation of recording processing, also have such a case: record data are retained in to write in the memory buffer 122 and do not record in the CD media 3.For this reason, when being through with recording processing, host apparatus 1 makes that to the order of CPU issue sync buffering being retained in the record data of writing in the memory buffer 122 is recorded in the CD media 3 and writes memory buffer 122 and become sky by master controller 10.
Reading memory buffer 123 is memory of data that temporary transient storage is read from CD media 3.The zone of about 1M byte has been assigned to and has read memory buffer 123 among the RAM12.When host apparatus 1 during to optical disc apparatus 2 issue reading orders, optical disc recording apparatus 2 to reading the memory buffer 123, promptly reads the sectors of data of beguine according to the big predetermined number of the sector number of reading order instruction from CD media 3 reading of data.When host apparatus 1 issue reading order with when CD media 3 is read next data, optical disc recording apparatus 2 is exported to host apparatus 1 in fact not from CD media 3 reading of data but will be stored in the record data of reading in the memory buffer 123.Therefore, can shorten the command response time.
Program execution memory 124 is used to control the storer of the program of CPU11 for storage.Placeholder record state control data storer 125 is for being used for the storer that temporary transient storage will record the recording status control data of CD media 3 when CD media 3 can not record data.Working storage 126 is for being used to store required memory of data such as CPU11 executive routine.
With reference to Fig. 1 and 5, the data array in the CD media 3 will be described below.CD media 3 comprises control data recording areas 130, Lead-In Area 131, data field 138 and leading-out zone 139 according to the such order of inner circumferential side from dish.
Control data recording areas 130 and Lead-In Area 131 are known as system region, wherein record the data of control or management CD media 3.Control data recording areas 130 be when with data recording in data field 138 time record be used for the zone of the recording status control data of record management.
Data field 136 is zones that are used for user data of CD media 3.The end of the posting field of leading-out zone 139 indication CD media 3.
These zones manage according to the territory element of 2048 bytes that are called the sector, and a series of numeral (address) is sent out by branch in described sector.Symbol " h " is placed to the end of the address among Fig. 1, so that represent the address that these are regional according to hexadecimal notation.By before data recording and processing, optical disc recording apparatus 2 being carried out initialization, control data recording areas 130 and Lead-In Area 131 are disposed in until in the zone of physical address 30000h, data field 138 is disposed in from the zone that physical address 30000h begins.Physical address 30000h is defined as logical address 0h.Host apparatus 1 visits CD media 3 by using logical address.Therefore, host apparatus 1 can not be visited the system region that is positioned on 138 inner circumferential side of data field.Yet, read the dish message command, read the DVD structure command, send quilt such as DVD structure command and prepare to make that according to the ANSI MMC-4 standard described in the 3rd conventional example host apparatus 1 can use the part of those data.
The logical address of record data must link up, because Write-once optical disc has the restriction that the continuum is write down.Therefore, optical disc recording apparatus 2 comes management data district 138 by data field 138 is divided into the zonule that is called the logic track.Subsequently optical disc recording apparatus 2 with data recording in track.Therefore, the restriction that the continuum is write down is met.Proposition can be managed maximum three logic tracks simultaneously in CD media 3.Described three tracks are known as first track, second track and stealthy track.Herein, stealthy track is the logic track that is arranged on the outermost of dish, and does not have predetermined end region.
The logic track is the zone of cutting apart configuration by the logical address space of the data field of the CD media 3 that can visit host apparatus 1.Because the length of track depends on the data that will write down, sevtor address carries out so the management of logic track is based on.In other words, the logic track is different from the physics track that pit for optical head 17 and record be listed as the guiding groove setting on the CD media 3.In the present invention, the record of user data and recording status control data is managed by the steering logic track.Therefore, hereinafter the logic track is abbreviated as " track ".In addition, optical disc recording apparatus 2 can produce a plurality of logical volumes as the virtual disk space on the Write-once optical disc 3, makes optical disc recording apparatus 2 each logical volume can be managed as a session.
Fig. 5 represents the configuration of CD media 3 of the present invention.As shown in Figure 5, CD media 3 comprises the first control data recording areas 130, the Lead-In Area 131 that is arranged in the system region.CD media 3 also comprises data field 138, wherein be furnished with track (#1) 132 ... track (#n-1) 133, track (#n) 134 and track (n+1).Track (#1) 132 to track (#n-1) 133 and track (n+1) are the track of user data.Track (#n) 134 is as the control data recording areas.
Be arranged on extending that control data recording areas 134 in the data field 138 is arranged from the first control data recording areas 130.Therefore, control data recording areas 134 need have continuity with the data in the first control data recording areas 130.Owing to this reason, control data recording areas 134 has following data management structure.
As shown in Figure 6, the traditional record state control data of DVD-R (in the 3rd embodiment, table 18) is configured to an ECC piece, i.e. 16 sectors.Therefore, ECC piece is used to each recording operation of the renewal recording status control data in the CD media 3.A sector in 16 sectors is to connect loss area (link loss area).According to ascending order field number (field number) is assigned to the first to the 15 sector, and memory contents is defined in advance.
The connection loss area is the interval between each district and does not have data.This zone is preserved for and conventional optical disc medium 3 compatibilities.
Shown in the table 19 in the 3rd conventional example, field 0 is the zone of storage general data, and it manages in various types of CD media usually.Shown in the table 21 of the 3rd conventional example, field 1 is the zone of storage medium power data, and described media power data are illustrated in the record condition in the recording operation of CD media 3, for example laser intensity etc.Field 2 is the zone that the dealer of optical disc recording apparatus 2 can freely use.Shown in the table 22 in the 3rd conventional example, field 3 is the zone of storage session data.Field 4 to 12 by the storage track control data for example the start address of generation track and the zone of end record address.Shown in the table 23 of the 3rd conventional example, field 4 also is the zone of storage about the track data of recording operation, and corresponding with the title division of TRAJECTORY CONTROL data.Shown in the table 24 of the 3rd conventional example, field 5 to 12 is the zones that are used for the storage track control data after field 4.Field 13 and 14 is reserve areas.
Set the TRAJECTORY CONTROL data 25 that are stored in the field 4 from the one group of start address and the end of record (EOR) address of the track that track number, each produced of distributing to first track, second track and stealthy track.Corresponding to 16th start address and the end of record (EOR) address that begin store each track that produce of track number from field 4.From the track number of following TRAJECTORY CONTROL data 25 is the start address and the end of record (EOR) address of each track with the TRAJECTORY CONTROL data setting.
According to the present invention, be expanded in data field 138, to be provided for the zone of stored record state control data according to the traditional record state control data of above-mentioned setting.Here, known five kinds of traditional recording status control data extended methods.
With reference to Fig. 7 and 8, will the management method of the control data recording areas of expanding be described in first data field.As shown in Figure 7, in the management method of described control data recording areas, the track number of the control data recording areas that indication is expanded in the data field is added to TRAJECTORY CONTROL data 25, and described TRAJECTORY CONTROL data storage is in the field 4 of recording status control data.So, track number is just become TRAJECTORY CONTROL data 30.
As shown in Figure 8, TRAJECTORY CONTROL data 30 comprise the beginning and the last recording address of stealthy track number, first track number, second track number, control data recording areas track number, reserved area and each track.Stealthy track number, first track number and second track number are the track number of stealthy track, first track and second track, and they are set so that manage simultaneously.Control data recording areas track number is the track number that is set to extend to the track of the control data recording areas in the data field 138.Start address that the start address of each track and last recording address are respectively the logic tracks (sevtor address) of setting in data field 138 and last recording address (sevtor address).Store according to the order of track number described each address.Along with the process of recording processing is provided with track continuously, and start-of-record address and last recording address.The reserved area is the zone of preparing for the data expansion in advance.
Since 2 byte area 31 of the 16 byte is the zone that is used for record control data recording areas track number that is arranged in the data field, though should be used as the reserved area in the zone in traditional DVD-R medium.Data track 132,133,135 except storaging user data ... outside, by zone 31 is provided, also control data recording areas 134 can be arranged in the data field 138 with the stored record state control data.
When being arranged on control data recording areas 134 in the data field 138, its track number n be stored in the TRAJECTORY CONTROL data 30 from 2 byte area of the 16 byte.Recover TRAJECTORY CONTROL data 30 or TRAJECTORY CONTROL data 26 according to track number n.Therefore, can obtain the start address and the last recording address of control data recording areas 134.
As mentioned above, in traditional DVD-R medium, when the control data recording areas 130 that produces in system region at initial phase has been used fully, even data have the zone of not using, can not user data.On the other hand, in the present invention, control data recording areas 134 is extended to the data field 138, and the recording status control data is recorded in this extended area.As a result, if data field 138 has the zone of not using, then can user data.
In addition, the reserved area since Eight characters joint shown in Fig. 8 can be used for the track number of record control data recording areas.In this case, can manage a plurality of control data recording areas.By using whole reserved area can extend to maximum 5 zones.
The management method of the control data recording areas that extends to second data field is described with reference to Fig. 7 and 9.In this management method, in TRAJECTORY CONTROL data 30, record two control data recording areas track number.In first management method of the control data recording areas that extends to the data field, zone can only store an indication extend to data field 138 control data recording areas 134 track number and be set in the TRAJECTORY CONTROL data 30.Owing to this reason, can point out to extend to the control data recording areas 134 of data field 138, it follows the first control data recording areas 130.Yet, can not store the data of indicating the zone that further expands.As a result, in first management method, need to keep the control data recording areas 134 of larger capacity.In second management method, the recording status control data is distributed to a plurality of control data recording areas.Therefore, can be with the capacity setting of each control data recording areas less.
In the management method of the control data recording areas that extends to second data field, the TRAJECTORY CONTROL data 30 that are stored in the field 4 shown in Fig. 7 have two track number, are used to point out the control data recording areas, as shown in Figure 9.In Fig. 9,, can manage being arranged on two control data recording areas 134 and 134 ' in the data zone simultaneously by zone 38 that the storage first control data recording areas track number is provided and the zone 39 of storing the second control data recording areas track number.
Be stored in the first control data recording areas track number indication of zone in 38 and extend to the track number of the control data recording areas of data field 138.That is to say, the first control data recording areas track number is the track number of the first control data recording areas in the recording status control data that is recorded in the first control data recording areas 130, that extend to data field 138, and is track number in the recording status control data in being recorded in the control data recording areas 134 that extends to data field 138, control data recording areas 134.
The second control data recording areas track number that is stored in the zone 39 is the track number that the next one extends to the control data recording areas of data field 138.That is to say that when the second control data recording areas was not set, the second control data recording areas track number was not recorded in the recording status control data that is recorded in the first control data recording areas.The second control data recording areas track number is the track number of the next control data recording areas of using 134 ', in its recording status control data in being recorded in the control data recording areas 134 that extends to data field 138.
After initialization CD media 3, control data recording areas 134 can not extend to data field 138 usually immediately.Therefore, the track number that is stored in the zone 38 and 39 also is not determined, and recording status control data being recorded in the first control data recording areas 130 by order.When control data recording areas 130 was set in data field 138 with expansion control data recording areas, the track number of control data recording areas 134 was recorded in the control data recording areas 130 that is used for the recording status control data that is arranged in the zone 38 as the first control data recording areas track number.At this moment, if the second control data recording areas also is not set, then zone 39 is not set up yet.
When recording processing was further carried out, the recording status control data was recorded in the control data recording areas 134.At this moment, the track number of control data recording areas 134 is set to the first control data recording areas track number.In addition, the second control data recording areas track number end is set up the control data recording areas 134 ' that will use up to the next one and is set up.When the control data recording areas 134 ' that will use when the next one was set up, the second control data recording areas track number was set to control data recording areas 134 '.
When setting area 38 and 39 by this way, and recording processing is when further carrying out, and the recording status control data just is recorded in the control data recording areas 134 '.At this moment, the track number of control data recording areas 134 ' is set to the first control data recording areas track number.In addition, the second control data recording areas track number not being set is set up up to the control data recording areas that the next one uses.
By repeating aforesaid operations, control data recording areas 134 can extend to data field 138 one by one.Therefore, the control data recording areas of expansion is configured to have a list structure.
In explanation so far, introduced the extended method of control data recording areas, wherein managed two track number of the control data recording areas of expansion.Yet, can expand described zone by another kind of method, wherein the indication extend to data field 138 the control data recording areas setting sign and should the zone track number be managed.
The method of the control data recording areas of administration extensions to the three data fields is described with reference to Figure 10 and 11 below.As shown in figure 10, in the method for the control data recording areas of administration extensions to the three data fields, except TRAJECTORY CONTROL data field 25 and 26, in field 14, also provide control data recording areas data field 40 so that management relates to the data of the control data recording areas that extends to data field 138.Be in field 14, to provide control data recording areas data area 40 with the difference of conventional art.In addition, though by using the track number that is provided with in data field 138 in first and second management methods to come the management control data recording areas, described the third management method is used to the sevtor address managed.
Control data recording areas data area 40 is record zones about the data of the control data recording areas that extends to data field 138.As shown in figure 11, control data recording areas data comprise the control data recording areas number in the data field 138, start address, end address and the last recording address of each control data recording areas.One group of start address of each control data recording areas, end address and last recording address can be recorded in the control data recording areas data field 40 up to 169 groups.The control data recording areas that is arranged in the data field 138 can be expanded until 169 zones.
All add the data of control data recording areas 134 when in data field 138, control data recording areas 134 being set at every turn.When control data recording areas 134 is new the interpolation, write down this regional start address and end address, and the quantity of the control data recording areas of expansion is updated and record.When writing down the recording status control data, all upgrade last recording address with record control data recording areas 134 at every turn.
Like this, according to the third management method, can manage or control a plurality of control data recording areas, and carry out described management based on the address date of each control data recording areas.Therefore, do not need track number is transformed into the address, and can realize simplification and acceleration processing procedure.
Herein, start address that can be by the calculation control data recorded area and the start address that is recorded in each track in TRAJECTORY CONTROL data 25 and 26 obtain the end address of control data recording areas.Therefore, when the CPU11 in the optical disc recording apparatus 2 operates with high speed,, also can obtain identical effect even the end address of control data recording areas is not recorded in the control data recording areas data 40.
Below, extend to the 4th kind of management method of the control data recording areas of data field with reference to Figure 12 explanation.As shown in figure 12, the 4th kind of management method is a kind of method that provides the control data recording areas data 40 in TRAJECTORY CONTROL data 30 and the control field 4 to be used to manage in field 4.As shown in figure 11,40 storages of control data recording areas data extend to the address of the control data recording areas 134 of data field 138.In addition, shown in Fig. 8 or 9, the track number of TRAJECTORY CONTROL data 30 storage control data recording areas 134.Therefore, in the 4th kind of method, come management control data recording areas 134 according to address and track number.
In TRAJECTORY CONTROL data 30, can consult the track number of last control data recording areas 134.In control data recording areas data 40, can consult the history of control data recording areas.Therefore, can crossing control data recording areas data 40 and TRAJECTORY CONTROL data 30 according to the situation of management control data recording areas 134.In other words, in the 4th kind of management method of the control data recording areas that extends to the data field, can also can manage a plurality of control data recording areas that are arranged in the data field according to TRAJECTORY CONTROL data 30 while management accounts each track in data field 138 by using control data recording areas data 40.
Below, extend to the 5th kind of management method of the control data recording areas of data field with reference to Figure 13 and 14 explanation.The 4th and the 5th kind of method between difference be that the data that will be stored in the field 14 are control data recording areas data 60 in the 5th kind of method, as shown in figure 13, and be control data recording areas data 40 the 4th kind of method.
As shown in figure 14, control data recording areas data 60 comprise the track number of control data recording areas number and each control data recording areas.The quantity of the expansion control data recording areas that the indication of control data recording areas number comprises in data field 138.The track number of each control data recording areas is expanded the track number of control data recording areas for each that comprises in data field 138.This track number is corresponding to the track number that is stored in TRAJECTORY CONTROL data 30 or 26, and can consult the address of each control data recording areas from the track number of each control data recording areas.Control data recording areas data 60 can be stored the track number of 1016 expansion control data recording areas altogether, and in the 5th kind of management method, can manage or control the expansion control data recording areas in 1016 zones altogether.Therefore, in the time will managing a plurality of control data recording areas, the 5th kind of management method is effective.
In the superincumbent explanation, control data recording areas data 40 or control data recording areas data 60 have been arranged in the field 14 of recording status control data.In addition, if in the recording status control data, there are control data recording areas data, but then administration extensions to the control data recording areas of data field.Therefore, can change its content according to the standard of CD media 3 part of the normalized sector of DVD-R for example, and can stipulate and arrange additional sector.
In addition, the address that in TRAJECTORY CONTROL data 30, control data recording areas data 40 and control data recording areas data 60, is provided with physical address normally.Yet it can be a logical address, because the record data directorial area that extends in the data field 138 is set in the logical address space.
Below, be control method under explicit and situation implicit expression with explanation as the logic track in the control data recording areas for host apparatus 1.
As mentioned above, can in data field 138, expand and be provided with control data recording areas 134.Yet, because the recording status control data that is recorded in the control data recording areas 134 is to be recorded in the system region in a conventional manner, so can in optical disc recording apparatus 2, finish and management data.Because control data recording areas 134 is arranged in data field 138, so regard the recording status control data as common user data according to identical mode.In addition, in optical disc recording apparatus 2, can not finish and the management accounts state control data.Therefore, in order to finish in optical disc recording apparatus 2 from the process of host apparatus 1 access control data recorded area 134 and the management accounts state control data, the legacy interface between host apparatus 1 and the optical disc recording apparatus 2 is modified.
At first, will illustrate the data about the track of management in the optical disc recording apparatus 2 are how to pass to host apparatus 1.Figure 19 be illustrated under optical disc recording apparatus 2 control track and according to the THE RELATIONSHIP OF THE PATH of host apparatus 1.As shown in figure 19, suppose to be provided with four tracks in the data field 134 of CD media 3: track #1, track #2, track #3 and track #4, user data are recorded among track #1, track #2 and the track #4, and the recording status control data is recorded among the track #3.Be that track #1, track #2 and track #4 are assigned to data track, and track #3 is assigned to the control data recording areas.Therefore, optical disc recording apparatus 2 falls the management of four tracks and is data track #1, data track #2, control data recording areas #1 and data track #3.
In optical disc recording apparatus 2, when based on track number during according to the request handled in the mode identical with conventional art from host apparatus 1, control data recording areas #1 also is treated to the user data track.Therefore, will reply to host apparatus 1 corresponding to the data of track #1, track #2, track #3 and track #4.Therefore, the data of data track #1, data track #2 and control data recording areas #1 and data track #3 are delivered to host apparatus 1.That is to say that the control data recording areas becomes as track and appears formula.For example, when host apparatus 1 visit track #3, need optical disc recording apparatus 2 notice host apparatus 1 data track #3 to be different from common data track.This will prevent that by by host apparatus 1 track #3 being treated to common data track paired domination number from carrying out unnecessary read-write operation according to recording areas.Host apparatus 1 also need the identification control data recording areas exist situation with the management CD media 2 the data field.
In optical disc recording apparatus 2, when the request from host apparatus 1 is treated to according to about the request of the track number of user data the time, promptly, when the control data recording areas be treated to system region or with system region similarly during the zone, will can not recover about the data of control data recording areas to host apparatus.Therefore, have only with the corresponding data of data track #1 (track #1), data track #2 (track #2) and data track #3 (track #4) and replied to host apparatus 1.As a result, the control data recording areas is stealthy as a track.For example, if when optical disc recording apparatus 2 is not shown as data track with the control data recording areas in data field 138, host apparatus 1 visit track #3, then optical disc recording apparatus 2 will with get rid of the corresponding data of track number of reassigning after the control data recording areas 134 that is assigned to data field 138 according to the recording status control data and reply to host apparatus 1.Therefore, the data of track #4 are identified as the data of track #3 by host apparatus 1.At this moment, host apparatus 1 does not need the control data recording areas in the recognition data district 138 so that manage the data field of CD media 3.Yet optical disc recording apparatus 2 need be made answer to the request from the eliminating control data recording areas 134 of host apparatus 1.
Like this, the method that in host apparatus 1 and optical disc recording apparatus 2 CD media 3 is managed is different according to the processing that extends to the control data recording areas 134 of user area 138.Therefore, order and the response that order is made has been expanded.The order relevant with the expansion of control data recording areas is to keep the track order and the track order that finishes.
The sector that the order of reservation track is used to by host apparatus 1 specified quantity keeps the order of a logical address area as a track.The order bag of traditional reservation track order has been shown in the table 499 of the 3rd conventional example.As shown in figure 17, a control data recording areas mark 70 is disposed on the position 0 of first byte of this order and is guaranteed as the control data recording areas by the track of this order reservation with instruction.Can be arranged in the 5th of this order for the sector number that obtains as the track of control data recording areas saves to the Eight characters.In addition, can provide and arrange a new command argument.Optical disc recording apparatus 2 receives and keeps the track orders, and when control data recording areas mark 70 when being genuine, and optical disc recording apparatus 2 is that the extra zone of reservation of described sector number 72 is as the control data recording areas.
The track order that finishes is to be used to finish, and promptly finishes the order of the record of regulation track.After the processing that finishes, optical disc recording apparatus 2 newly is provided with a stealthy track.Therefore, as shown in figure 18, control data recording areas extension bits 80 is disposed on the position 3 of second byte of tradition order bag to indicate whether to allow to be provided with the control data recording areas before stealthy track newly is set.
Host apparatus 1 uses the order of request sensing, read the dish message command, read trace information order etc. so that obtain the state of optical disc recording apparatus 2 and the state of CD media 3.
Request sensing order is the order of state that is used to obtain optical disc recording apparatus 2 by host apparatus 1 issue.Traditional, if when the state of optical disc recording apparatus 2 changes, when perhaps optical disc recording apparatus 2 has been finished given order, the data that are notified to host apparatus 1 from optical disc recording apparatus 2 are arranged, then this order has been published.When the quantity in the residue record controls district that is provided with in system region or the data field was less than a threshold value, optical disc recording apparatus 2 was to host apparatus 1 circular state.When receiving status information, host apparatus 1 will ask the sensing order to send optical disc recording apparatus 2 to.Therefore, the order issue has strengthened.Host apparatus 1 is from obtaining required data to the response of request sensing order.
When host apparatus 1 can be identified as data track with the control data recording areas that extends to the data field, need distinguish the track that records user data and the track of control data recording areas.For this reason, be used to obtain the plate-like attitude read that dish message command and user obtain track state read the trace information order by expansion as described below.
With reference to Figure 15, with the expansion that illustrates the response data that reads the dish message command.In the table 368 of the 3rd conventional example, illustrated reading traditional corresponding data of dish message command.As shown in figure 15, the number of times 71 of the expansion of the control data recording areas in control data recording areas mark 70 and the data field is added in the response data.
The value of the position 5 of second byte of command response data is used as control data recording areas mark 70, and when having control data recording areas 134 in data field 38, described mark becomes " 1 ".In addition, the 32nd byte of command response data is used as the zone 71 of storage control data recording areas expansion number of times, and indicates the quantity data that is present in the control data recording areas in the data field 138 to be added in the command response data.These data can be arranged in described in the table 368 of the 3rd conventional example other and not use in the zone, and can add these data after changing the clauses and subclauses that the command response data length is arranged in the OPC table in 34 to the n bytes.
With reference to Figure 16, with the expansion that illustrates the response data that reads the trace information order.In the table 463 of the 3rd conventional example, illustrated reading the conventional response data of trace information order.As shown in figure 16, control data recording areas mark 70 is added in the response data.The data of the position 6 of the 5th byte of these command response data are used as control data recording areas mark 70, and when the track according to described order appointment was the control data recording areas, described mark became " 1 ".After having obtained the response data that reads the trace information order, host apparatus 1 is recognized does not need to carry out read/write process, because if control data recording areas mark 70 is " 1 ", then described track is a control data recording areas track.
The mark position that should note the control data recording areas can be arranged in by a part of data of definition in the table 463 that changes the 3rd conventional example in the part.In addition, can be in initiate a part of data byte with described location arrangements.
The extended method that is arranged in the control data recording areas in the data field that control data recording areas by using expansion thus and described order are carried out in optical disc recording system will be described below.
In CD media 3, system region is arranged in the zone that is equal to or less than the 30000h physical address, and the data field is arranged in the zone that is equal to or higher than the 30000h physical address.Control data recording areas 130 and Lead-In Area 131 are arranged in the system region.Track 132,133,134 and 135 is arranged in the data field 138 with user data.Track 134 in these tracks is set up as the control data recording areas.Just the stealthy track of host apparatus 1 issue finish during the track order or during when the order of its issue acquisition control data recording areas, by control data recording areas 134 being arranged in the expansion of carrying out the control data recording areas in this data field 138.That is, need be in being published on stealthy track the writing of record data (10) order or keep the order that issue after the track order that finishes of issuing stealthy track before the reservation track order of a logic track obtains the control data recording areas.This be because during stealthy track at the outermost track of dish, and determine the end address according to the recorded data amount that finishes up to track.
With reference to Fig. 5 and 20, with the first method of explanation optical disc recording apparatus 2 automatic expansion control data recording areas.In first operation, when finishing during the track order of the stealthy track of host apparatus 1 issue, if the quantity of the remaining area of the control data recording areas of record current record state control data is equal to or less than a threshold value, then optical disc recording apparatus 2 with from the irrelevant expansion control data recording areas 134 in data field 138 of the order of host apparatus 1.
When host apparatus 1 issue track number is the finishing during the track order of stealthy track 133 of # (n-1), optical disc recording apparatus 2 is in response to the described order track # (n-1) that finishes.Then, optical disc recording apparatus 2 writes down a recording status control data that upgrades in the first control data recording areas 130.Quantity at the remaining area of the first control data recording areas 30 is equal to or less than described threshold value, and then optical disc recording apparatus 2 keeps control data recording areas 134 for the sector of the predetermined quantity among the track #n.If control data recording areas 134 is new the reservation in data field 138, then optical disc recording apparatus 2 write down a mark and is expanded to the data field to indicate the control data recording areas in system region.In addition, optical disc recording apparatus 2 is present in the quantity and the recording status control data of the control data recording areas in the data field 138, then the recording status control data that upgrades is recorded in the first control data recording areas 130 of CD media 3.
Then, optical disc recording apparatus 2 produces a new stealthy track 135 in track # (n+1), and upgrades the recording status control data, then the recording status control data that upgrades is recorded in the first control data recording areas 130 of CD media 3.Optical disc recording apparatus 2 notice host apparatus 1 track number is that the finishing of track of # (n-1) handled the such fact of normal termination and indicated control data recording areas 134 to be expanded the state of such fact recently in response to the track order that finishes.Therefore host apparatus 1 not only detects the response data indication normal termination to the track order that finishes, and in the state-detection CD media 3 of the control data recording areas by receiving expansion by the data of user management but not track have a situation.In addition, do not expanded the control data recording areas from the order of main frame, so the value that the residue sector number of the data field 138 in the CD media 3 and host apparatus 1 keep is inconsistent because in optical disc recording apparatus 2, have to rely on.For this reason, the order that the empty sector number in the CD media 3 is obtained in host apparatus 1 issue, and the empty sector number in the affirmation CD media 3.In addition, when host apparatus 1 joined data in the CD media 3, host apparatus 1 used the order of state of acquisition dish or track so that obtain data track number or track state in the CD media 3.Host apparatus 1 is determined next recordable logical address according to the data of obtaining.
In the superincumbent explanation, illustrated that the quantity of the remaining area of the first control data recording areas 130 is equal to or less than threshold value such a case.Yet, should be noted that if the control data recording areas can extend further to data field 138, even the quantity of the remaining area in the first control data recording areas 134 that extends in the data field 138 is equal to or less than threshold value, also can realize identical operations.
With reference to Figure 20 explanation the control data recording areas is extended to the operation of the CPU11 in the first method of data field below.When host apparatus 1 during to optical disc apparatus 2 issue an orders, CPU11 analyzes order to determine whether the order that receives is the track order (step S202) that finishes.If the order that receives is not finish track order (step S202-is not), then finishing control.If the order that receives is the track order (step S202-is) that finishes, then carries out the track that finishes and handle (step S203).In the track that finishes is handled, not not hiding with virtual data in the reserve area with the sector.Then, the recording status control data that upgrades is recorded in the control data recording areas 130 or control data recording areas 134 of CD media 3.
Determine then whether the track that finishes is stealthy track (step S204).If the track that finishes is not stealthy track (step S204-is not), the operation of command response data and finishing control then is set, because it is not the end process of stealthy track.
On the other hand, if the track that finishes is stealthy track (step S204-is), then the quantity of remaining area and the threshold value of control data recording areas are compared (step S205).Result as a comparison is when the quantity of remaining area equals and during less than described threshold value (step S205-is not), control data recording areas 134 is set in the data field 138 as control data recording areas (step S206).In the processing that the control data recording areas is set, be set for the stealthy track 133 of end for the control data recording areas 134 of predetermined sector number, and the start address of newly-installed control data recording areas 134 and end address are set up and upgrade.Herein, known a kind of like this method, wherein use newly-installed control data recording areas 134 other control data recording areas outside newly-installed control data recording areas 134 to fill up predetermined data, perhaps these zones are used fully, will describe this method in the back in detail.
Then, new stealthy track (step S207) and the command response data are set and finish described process of commands is set.When the quantity of the remaining area of control data recording areas during greater than described threshold value (step S205-is), carry out stealthy track set handling (step S207).Then, command response data and finish described process of commands are set.
In stealthy track set handling (step S207), the stealthy track that is used for the data that next time will write is reset, and upgrades the recording status control data of newly-installed stealthy track and finish described command process.
In first kind of operation, the threshold value of the quantity of remaining area and control data recording areas is compared (step S205) each other and is carried out control data recording areas set handling (step S206).Therefore, the setting of control data recording areas in data field 138 is possible, but this set can not be carried out by traditional optical disc recording apparatus.
In the present embodiment, introduced the program that to carry out by CPU11 as an example.Can realize identical operations by using logical circuit.
Below, explanation can be managed under the situation of a plurality of control data recording areas two kinds of recording methods that new control data recording areas are arranged on the data field simultaneously at above-mentioned optical disc recording apparatus 2.
In first kind of recording method, existing control data recording areas has not been filled predetermined data with the zone before arranging new control data recording areas 134.Therefore, because 2 any moment of optical disc recording apparatus all are not enough to manage a control data recording areas, in a single day so CD media 3 is inserted in the optical disc recording apparatus 2, optical disc recording apparatus 2 just can be searched for nearest recording status control data fast.Herein, Yu Ding data are configured to nearest recording status control data or virtual data.
In second kind of recording method,, do not use new control data recording areas 134 not used up fully up to existing control data recording areas with the zone even control data recording areas 134 is newly-installed yet.The recording status control data is recorded in not using in the zone of existing control data recording areas.In second kind of recording method, because when being inserted into CD media 3 in the optical disc recording apparatus 2, searched for nearest recording status management data from a plurality of control data recording areas, therefore, second method is not so good as first method in the search speed method, but the control data recording areas can access effective use.
Here, will the threshold value of the remaining area quantity of control data recording areas be described.The threshold value of the remaining area quantity of control data recording areas should have than big twice of data track number or the bigger value that can open simultaneously.There is such a case:, for example keep the track order and the order of the track order that finishes also is distributed to video disc recording pen recorder 2 even data recording operation is not performed.Therefore, the control data recording areas need be upgraded two recording status control datas.For example, in above-mentioned operation as shown in Figure 2, keep track order, synchronization caching order and the track order that finishes and be distributed to first track and second track.Therefore, need three recording status control datas, need four recording status control datas, (=3*2+4) the individual recording status control data that as the result of this process, needs 10 from step 5 to step 9 for stealthy track for track.Consider that the synchronization caching order is distributed to a track repeatedly by actual, it is about five times of the track opened simultaneously that preferred described value is set to.Therefore, the threshold value of the volume residual of preferred control data recording areas is for example 15 in the present embodiment.
In addition, when the frequent renewal recording status control data of optical disc apparatus 2, effectively raise than previous control data recording areas extend to the data field the normally used threshold value threshold value of Duoing, even perhaps remaining area is greater than threshold value, also the control data recording areas can be extended to the data field.
In addition, the predetermined sector number in the expansion of control data recording areas can be similar to identical with the sector number that obtains in the first control data recording areas 130.Sector number, the quantity of recording status control data and the control data recording areas that the empty sector number in the data field can obtain to adapt to from data field 138, used.For example, can determine predetermined sector number by following equation:
(predetermined sector number)=(the empty sector number in the data field)/(sector number of use) * (quantity of recording status control data)
The control data recording areas 134 that the average record size of data of data by record and the free zone of data field 138 are calculated and obtained to adapt to.Therefore, can carry out effective record data management to CD media 3.In addition, CD media device 2 normally writes down by every ECC piece.Therefore, sector number becomes the multiple of the sector number that is used for the ECC piece.For example, the value of 400 ECC pieces (6400 sectors) sector number that is set to be scheduled to.
In addition, optical disc recording apparatus 2 comprises that in RAM12 placeholder record state control data storer 125 is used to store a plurality of recording status control datas.Be published repeatedly such a case for synchronization caching order before control data recording areas 134 being extended to data field 138, the recording status control data that will upgrade is stored in the placeholder record state control data storer 125.Therefore, even the control data recording areas is short being finished up to stealthy track, optical disc recording apparatus 2 also can normal running.
Second kind of extended method of the control data recording areas of being undertaken by optical disc recording apparatus 2 is described with reference to Fig. 5 and 21 below.In second kind of extended method, 2 of optical disc recording apparatus are just expanded the control data recording areas when host apparatus 1 allows.
When host apparatus 1 issue is used for finishing during the track order of stealthy track, be added with the expansion of control data recording areas in the wherein said order and allow mark, when the remaining area that allows mark indication " very " and store the current control data recording areas of current record state control data in expansion became and is equal to or less than threshold value, optical disc recording apparatus 2 extended to the data field with the control data recording areas again.
When host apparatus 1 determined that permission extends to data field 138 with control data recording areas 134, the expansion of the control data recording areas in this order allowed mark 80 to be set up the state that comes true in the track command procedure that finishes of the stealthy track of issue.
In Fig. 5, when finishing the track order for (n-1) track issue as stealthy track, expansion allows mark 80 to be set up the state that comes true.When the argument of the track order that finishes indicates stealthy track as target trajectory, when expansion allows mark 80 to be equal to or less than threshold value for the quantity of the remaining area of the control data recording areas in true and the CD media, after stealthy track was finished, optical disc recording apparatus 2 obtained a new control data recording areas 134 in track #n.Like this, newer stealthy track # (n+1) is just by continuous providing.
Allow mark 80 whether should be set up the state that comes true for the expansion of control data recording areas herein, and whether depend on the processing sequence that is used for allowing at host apparatus 1 in the process that is used for the track order that finishes of stealthy track from host apparatus 1 issue.Therefore, the state of optical disc recording apparatus 2 is to determining not influence.In other words, even the control data recording areas of optical disc recording apparatus 2 less than threshold value, when the permission mark 80 of control data recording areas is " mistake " or when being reset, is not carried out the expansion of control data recording areas.When the address date of being managed by host apparatus 1 during CD media 3 is carried out recording operation should not change, the permission mark 80 of control data recording areas was reset and forbids with indication.For example, when host apparatus 1 writes down the file management data that is present in the CD media 3, there is such a case: if be not by using logical address but by from the offset address indication of a certain reference address with the position of record, then because the control data recording areas is present between the data track, offset address will change.
In addition, when the control data recording areas of CD media 3 is equal to or less than threshold value, as the response data of writing (10) order and synchronization caching order to issuing from host apparatus 1, optical disc recording apparatus 2 is given host apparatus 1 with such state notifying: promptly this state points out that the quantity of remaining control data recording areas is equal to or less than the such fact of threshold value.The expansion of the control data recording areas that stealthy track is set that like this, host apparatus 1 can be suitable allows mark.
The state that optical disc recording apparatus 2 notice host apparatus 1 is such: promptly this state points out that track finishes by the such fact of normal termination, and as the finish response of order of track, the control data recording areas is expanded again.Host apparatus 1 not only receives the indication track status information of response data of normal termination that finishes, but also receives the status information of the expansion of indication control data recording areas.Therefore, host apparatus 1 can detect in CD media 3 and exist by the data outside the data in the track of user management.As a result, undertaken to realize suitable processing under the situation of data management by using track number at host apparatus 1.
In addition, when host apparatus 1 when CD media 3 is added data, host apparatus 1 uses the order of obtaining the order of plate-like attitude and obtaining track state to obtain track number and track state in the CD media 3.Host apparatus 1 is based on the logical address of the definite data that will write down of the status information of obtaining.
Below, expand to the operation of CPU11 in second kind of extended method in the data field with reference to Figure 21 explanation in the control data recording areas.When host apparatus 1 during to optical disc apparatus 2 issue an orders, CPU11 analyzes order.Determine whether the order that receives is the track order (step S212) that finishes.If the order that receives is not the track order (step S212-is not) that finishes, then finishing control operation.If the order that receives is the track order (step S212-is) that finishes, then carries out the track that finishes and handle (step S213).In the track that finishes is handled, carry out the processing of not using the sector of filling reserve area with virtual data.Then, the recording status control data that upgrades is recorded in the control data recording areas 130 or control data recording areas 134 of CD media 3.
Then, determine whether the track that finishes is stealthy track (step S214).If the track that finishes is not stealthy track (step S214-is not), because the processing of stealthy track is not finished, the command response data is set then, and finishes described processing.
If the track that finishes is stealthy track (step S214-is), check that then the expansion of control data recording areas allows mark 80, it is to the track order setting that finishes.(step S218).If the expansion of control data recording areas allows mark 80 indication enable states (step S218-is), then quantity and the threshold value with the remaining area of control data recording areas compares (step S215).Result as a comparison is when the quantity of remaining area equals and during less than described threshold value (step S215-is not), control data recording areas 134 is set in the data field 138 as control data recording areas (step S216).In the processing of control data recording areas, the control data recording areas 134 of predetermined sector number is set at after the stealthy track 133 of end, and the start address of newly-installed control data recording areas 134 and end address are set up in the recording status control data and upgrade.Herein, other control data recording areas outside the newly-installed control data recording areas 134 has been filled up predetermined data, does not perhaps use newly-installed control data recording areas to be used up fully up to existing control data recording areas, as hereinafter described.
Then, new stealthy track (step S217) and the command response data are set and finish described process of commands is set.
When the expansion of control data recording areas allows mark 80 indications not allow (step S218-is not) or when the quantity of the remaining area of control data recording areas during greater than described threshold value (step S215-is), carry out stealthy track set handling (step S217).And the command response data are set to finish described processing.
In stealthy track set handling (step S217), the stealthy track that is used for the data that next time will write is reset, and upgrades the recording status control data of newly-installed stealthy track and finish described processing.
And the difference of the operation of the CPU11 in first kind of above-mentioned operation is: the step (step S218) that has added definite control data recording areas extending marking between the step (step S215) of the volume residual of the step (step S214) of determining stealthy track and comparison control data recording areas and threshold value.By the step (step S208) of determining control data recording areas extending marking is provided, when optical disc recording apparatus 2 should expand the control data recording areas if can identifying host apparatus 1.Therefore, when host apparatus 1 was controlled optical disc recording apparatus 2 in detail, this method was effective especially.
In the present embodiment, introduced the program of carrying out by CPU11 as an example.Yet, can realize identical operations by using logical circuit.
The third extended method of the control data recording areas of being carried out by optical disc recording apparatus 2 is described with reference to Fig. 5 and 21 below.In the third extended method, optical disc recording apparatus 2 is expanded the control data recording areas under the control of host apparatus 1.
Host apparatus 1 is distributed on the order that keeps the control data recording areas on the data field after the track order that finishes of stealthy track.Then, optical disc recording apparatus 2 bases extend to the data field from the request of the area size of host apparatus 1 again with the control data recording areas.
In addition, optical disc recording apparatus 2 is notified such fact by user mode information to host apparatus 1: the quantity in the current residual zone of control data recording areas becomes and is equal to or less than threshold value.Therefore, host apparatus 1 can be distributed on the order that keeps the control data recording areas on the data field.
When (10) order and synchronization caching order are write in the track # of 1 pair of stealthy track of conduct of host apparatus (n-1) issue, the state that optical disc recording apparatus 2 notice host apparatus 1 is such: the quantity of the remaining area of this state indication control data recording areas is equal to or less than threshold value, if the remaining area of the control data recording areas of CD media 3 is equal to or less than threshold value, then with such status information as the command response data.Host apparatus 1 is checked the state of command response data, and end record is handled and the track order that finishes of issue track # (n-1).
Then, when the remaining area of the state indication control data recording areas of notifying from optical disc recording apparatus 2 is equal to or less than threshold value, host apparatus 1 is provided with the sector number that is obtained for the control data recording areas of advocating, and is distributed on the order that keeps the control data recording areas in the data field 138.Optical disc recording apparatus 2 is provided with the control data recording areas for the sector number of request in track #n.Then, optical disc recording apparatus 2 is reset stealthy track # (n-1).Optical disc recording apparatus 2 is provided with normal termination in the command response data, and replys host apparatus 1.Keep or when the order normal termination of control data recording areas 134 was set, host apparatus 1 can identify the track number of stealthy track or will the logical address of the recordable data of stealthy track be changed next time when being used in the data field 138.Therefore, host apparatus 1 uses and reads the dish message command and read the trace information order, and obtains data track number and track state in the CD media 3, determines to record the logical address of the data in the stealthy track then.
When control data recording areas mark 70 is being provided with of track reservation order, although the remaining area of control data recording areas is greater than threshold value, optical disc recording apparatus 2 can be provided with a mistake and not obtain the control data recording areas as the command response data, perhaps can obtain for from the control data recording areas of the request sector number of host apparatus 1 and stealthy track # (n+1) can be set.
As mentioned above, as the order that in the data field, keeps the control data recording areas, used the order of reservation track.Optical disc recording apparatus 2 receives reservation track order and keeps for the track that regains as the sector number 72 of control data recording areas.
Here, obtain to be configured to as the sector number 72 of control data recording areas the multiple of ECC piece, because recording operation carries out with every ECC piece, and ECC of control data recording areas use is used for once upgrading.
Therefore, the preferred zone that obtains greater than the ECC piece number of threshold value.Should note when record cell is sector location, can replace the ECC piece with the sector.
The operation of CPU11 in the third method that the control data recording areas is extended to the data field is described with reference to Figure 22 below.When host apparatus 1 during to optical disc apparatus 2 issue an orders, whether CPU11 analyzes order serves as to keep track order (step S220) with the order of determining to receive.If the order that receives is not to keep track order (step S220-is not), then finishing control operation.If the order that receives is to keep track order (step S200-is), then determine to keep the control data recording areas mark 70 (step S221) of track order.If control data recording areas mark 70 is pointed out the control data recording areas (step S221-is) is set, then carry out the control data recording areas set handling (step S222) that new control data recording areas 134 is set in data field 138, and the finishing control operation.If control data recording areas mark 70 is not pointed out control data recording areas setting (step S221-is not), determine then whether first track is not used (step S223).If first track is not used (step S223-is), then carry out the reservation process of first track.Because first track is not used, so in the first track reservation process, be retained as first track based on the sector number that keeps track command argument regulation.Then, upgrade recording status control data (step S224).Afterwards, finishing control operation.
If first track has been used (step S223-is not), determine then whether second track is not used (step S225).If second track is not used (step S225-is), then carry out the reservation process of second track.Because second track is not used, thus in the second track reservation process, be used as second track based on the sector number that keeps track command argument regulation, and upgrade recording status control data (step S226).Afterwards, finishing control operation.If second track also has been used (step S225-is not), then carry out a fault processing.In this fault processing, the error condition that is produced is set at (step S227) in the command response data, and the finishing control operation.
The control data recording areas is being extended in the third extended method of the 3rd data field, definite processing (step S221) by the control data record mark 70 that keeps the track order is provided and new control data recording areas 134 is arranged on control data recording areas set handling (step S222) in the data field 138, it is feasible that the control data recording areas extends to the data field, and this mode is inexecutable forever in traditional optical disc recording apparatus.
In the present embodiment, the program of being carried out by CPU11 has been described as an example.Can realize identical operations by logical circuit.
As mentioned above, when the control data recording areas in finishing of stealthy track handled be shortage the time, control data recording areas 134 is repositioned in the data field 138 after stealthy track.When being provided with a plurality of logical volume that is called session in CD media 3, the border of session is designated as system region.Therefore, the control data recording areas that has with the first control data recording areas, 130 identical functions can be arranged in the session border.
When providing a plurality of session in Write-once optical disc 3, it is in the possible session that the data field is set at addition record.Control data recording areas of the present invention can be applicable in this data field.
In addition, when host apparatus 1 was attempted directly to visit the control data recording areas of being managed by optical disc recording apparatus 2, optical disc recording apparatus 2 returned or replys a mistake.That is, write (10) and order or when reading (10) order, optical disc recording apparatus 2 returns mistake and do not carry out the write and read operation when 1 pair of host apparatus is assigned to logical address issue in the track of control data recording areas.Like this, though traditional only being arranged in the system region of recording status control data, the visit that can prevent user error when being arranged in the recording status control data in the data field is arranged in the control data recording areas in the data field.Especially, when the indication logical address had specified the data of control data recording areas to be notified to host apparatus in wrong return course, host apparatus 1 can effectively be controlled optical disc recording apparatus 2, because it does not need to carry out retry operation etc.
Figure 23 represents the process flow diagram when optical disc recording apparatus 2 receives the order of the logical address that is used for input and output control data recording areas.The difference of operating with traditional input and output is: in the present invention, provide the definite processing (step S241) of control data recording areas and the notifier processes (step S244) of control data restrict access.In the control data recording areas is determined to handle, determine whether the logical address for input and output is the control data recording areas.
When host apparatus 1 receives order, 2 pairs of orders of optical disc recording apparatus are analyzed.Determine whether the order that receives is I/O order, for example read command and write order (step S240).If the order that receives is not I/O order (step S240-is not), then finishing control operation.If the order that receives is I/O order (step S240-is), determine that then whether for the logical address of input and output be address (step S241) in the control data recording areas.If described logical address is not the address that is used for input and output (step S241-not) in the control data recording areas, then optical disc recording apparatus 2 is carried out common I/O operation because it not input and output give the control data recording areas.In the I/O operation, read user data and record user data up to (step S242) the CD media 3 from CD media 3.Afterwards, in the I/O state notifying was handled, the state during input and output finish was configured to the command response data with notice host apparatus 1 (step S243), finishing control operation then.
If the logical address that is used for input and output is then carried out directorial area restrict access notifier processes control data recording areas (step S241-is), because it is transfused to and exports to the control data recording areas.Visit in the limited processing in directorial area, the data of expression reference address indication control data recording areas are set in the command response data with notice host apparatus 1 (step S244), and the finishing control operation.
Afterwards, with explanation when control data recording areas 134 is present in the data field 138 of CD media 3 host apparatus 1 by using above-mentioned reading the dish message command and read the method that control data is obtained in the trace information order.
As shown in figure 15, comprise that flag data and the control data recording areas number in the data field that whether track number, control data recording areas in the whole panel of control data recording areas are present in the data field are set in the command response data that read the dish message command.Use these data, host apparatus 1 can be determined the total number of tracks in the CD media 3, can not operated track have a situation and can not operated track number.In order to determine that track is the control data recording areas, the trace information order is read in continuous issue for the number of track altogether the CD media that begins from track number #1.As shown in figure 16, control data recording areas mark 70 is set to the response data that reads the trace information order to indicate whether described track is the control data recording areas.
