Embodiment
To do detailed reference to the preferred embodiments of the present invention now, the example of preferred embodiment illustrates in the accompanying drawings.In institute's drawings attached, anyplace, will use identical label to indicate identical or similar parts.
Hereinafter the preferred embodiments of the present invention will be described with reference to the accompanying drawings.
Before explanation the present invention, it should be noted among the present invention disclosed most of terms corresponding to well-known generic term in this area, but some term defending parties to the application choose because need, and open in explanation of the present invention subsequently.Therefore, the defined term of applicant is preferably based on their meanings in the present invention and understands.
A kind of recording medium used in this invention is represented all recordable medias, for example, and CD, disk and tape etc.
For the convenience that illustrates and for to better understanding of the present invention, hereinafter will exemplarily use CD-WORM (being BD-R) to be used as the recording medium in the invention described above.
Fig. 2 illustrates a kind of being used in CD-WORM (being BD-R) method for recording data.
With reference to figure 2, BD-R comprises introducing section, data segments and draws section.Data segments comprises inner spare area (ISA), outer spare area (OSA) and the user data area that is used for storing therein actual user data.This ISA is positioned at the front end of data field, and OSA is positioned at the rear end of data field.
Introduce the section record multiple in CD record data/from the needed management information of optical disc reproducing data.Specifically, introduce section and also comprise interim CD managing district (TDMA), wherein record the defect management information and the records management information of CD.
TDMA is suitable for aforesaid defective and the records management information that often generates when using CD upgraded.An additional TDMA also can optionally be assigned to and distribute aforesaid spare area.
Aforesaid CD-WORM (being BD-R) uses two kinds of data record methods, i.e. sequential recordng mode (SRM) method and recorded at random pattern (RRM) method.
The user data area that the SRM method will be stored actual user data is divided into a plurality of continuous zones, makes data to be recorded in the CD like a cork.Each aforesaid zone that is divided is called as track or SRR (journal scope).The zone that is divided in the present invention will be called as SRR hereinafter.
Be used in data recording among the SRR and be in expression in next the not record that can write record not bunch bunch and realize.But the record bunch the address be known as next write address (NWA).In other words, the next one of the prerecorded zone that is comprised among the SRR bunch serves as NWA, and data recording operation begins at the NWA place.Therefore, if data by from certain location (being NWA) record continuously, NWA is just along with data recording operation dynamically increases.
In this case, because the existence of NWA, the SRR of record data is called as and keeps SRR or open SRR therein.For the convenience that illustrates, this SRR is called as open SRR in the present invention.
Can distribute two or more open SRR to carry out data recording operation.A SRR can be used as the file system data district, be used to store the information relevant with user data, and another SRR can be used as the user data area of user data.
File system data is represented the name information and the video disc recording positional information of institute's include file in the CD, to such an extent as to make subscriber data file can be in CD record/from optical disc reproducing.In other words, main frame or application program utilize aforesaid file system data to write down or the CD of regenerating in the specific file that comprised.
Therefore, above-mentioned file system data comprises the name information in hierarchial file structure/path, and the pointer information of representing the size/position data in above-mentioned file/path.
According to above-mentioned SRM method, when receiving the request of application program or main frame, can produce with single SRR in the relevant rewrite command of prerecorded zone that comprised.In this case, because the feature of BD-R, the video disc recording operation can physically be carried out once, is not allowed to such an extent as to the data recording operation relevant with prerecorded zone is overwrite function.Yet, be recorded in data in the above-mentioned prerecorded zone and can be recorded among next NWA that can write in the user data area to be comprised, rather than be recorded in prerecorded zone.Above-mentioned alternative recording operation is called as logical overwrite operation, and this logical overwrite operation is different with the physical overwrite operation of BD-RE.
To describe above-mentioned logical overwrite method in conjunction with the accompanying drawings hereinafter.
Fig. 3 shows the method in BD-R logical overwrite data of being used for according to a first advantageous embodiment of the invention.
With reference to figure 3, when receiving the relevant data recording order of the prerecorded zone that comprised with single SRR, the data that be recorded in the prerecorded zone are recorded among the NWA that represents next writable area, rather than are recorded in the prerecorded zone.
In more detail, if the FS data field of SRR#1 is owing to open SRR is served as in the existence of NWA, among the NWA that data just are recorded among the SRR#1 to be comprised.If the user data area of SRR#2 is owing to open SRR is served as in the existence of NWA, among the NWA that data just are recorded among the SRR#2 to be comprised.
According to the present invention, if with CD-WORM (being BD-R) in the relevant data recording order (being rewrite command) of prerecorded zone that comprised, data be recorded in the immediate NWA in the district of reception channel rewrite command in, rather than be recorded in the prerecorded zone.
Therefore, as seen in fig. 3, if single SRR comprises NWA, this SRR serves as open SRR.If this SRR has enough spaces to store the data of hope, data are recorded among the corresponding SRR (promptly having carried out the alternative recording operation relevant with corresponding SRR) by first.
Carried out alternative recording operation if as above tell in person with stating, received the primary importance information in zone of data rewrite order and another the regional second place information that carry out to substitute recording operation at its place and be recorded in the specific region of CD.For example, primary importance information and second place information are registered as the LOW input item of CD TDMA.
Above-mentioned positional information can be by corresponding bunch first physical sector number (PSN) expression.Preferably, if logical overwrite operation satisfies a plurality of bunches size information, can utilize two input items respectively a PSN of first bunch and a PSN of last bunch to be carried out record.
Therefore, if the user wishes the data of coming first district of regenerative reception rewrite command with reference to the LOW input item information that writes down in TDMA, the data that are stored in second district of the alternative recording operation of its place's execution data will be reproduced, rather than regeneration is stored in the data in first district.
Therefore, though the data that will be recorded in first district that receives rewrite command physically are recorded in second district of serving as the alternate area, actual main frame is identified as data and is rewritten in first district that receives rewrite command.
When carrying out above-mentioned logical overwrite order, the alternative posting field of carrying out the alternative recording operation place that is associated with the logical overwrite order may be not enough for alternative recording operation, hereinafter will at length explain this point with reference to figure 4.
In more detail, at first in the SRR of correspondence, be performed according to the performed alternative recording operation of rewrite command.Yet, do not substitute the desired zone of recording operation if do not comprise among the corresponding SRR, preferably data are recorded among another SRR of contiguous corresponding SRR.
Fig. 4 represent according to a second, preferred embodiment of the present invention in BD-R the method for logical overwrite data.
As seen in fig. 4, the SRR# 1 that the data rewrite order that is associated with the prerecorded zone of SRR# 1 can wherein be recorded file system (FS) data receives.In this case, if SRR# 1 is owing to open SRR is served as in the existence of NWA, in NWA, carry out substituting recording operation.
When carrying out above-mentioned alternative recording operation, substituting recording areas may be not enough for aforesaid alternative recording operation.
In this case, corresponding to the remaining area of SRR# 1, the alternative recording operation of data is performed for several times, and the remaining data that its alternative recording operation is not performed is recorded among the NWA of the SRR that closes on.In other words, some data are recorded among the NWA of SRR# 1, and remaining data are recorded among the NWA of another SRR that closes on SRR#1.Fig. 4 exemplarily is illustrated in the alternative recording operation of carrying out among the SRR# 2.
In this case, the SRR# 2 that wherein carries out the alternative recording operation of remaining data can represent user data area.In this case, wish identical data are recorded among the single SRR.Preferably, the SRR# 2 of storaging user data is closed, and a new SRR is assigned with, and data are recorded among the new SRR.
For example, the data representation file system data of SRR#1.Therefore, if file system data is recorded among the SRR# 2, and record the user data different with file system data among the SRR# 2, then SRR# 2 is automatically closed, and a new SRR is assigned with, and data are recorded among the new SRR.
Therefore, the SRR# 2 of storaging user data is closed, and new SRR# 3 is assigned with, and is recorded in SRR# 3 so that be used for the residue file system data of logical overwrite operation.
As a result, user data is recorded among the SRR# 2, and file system data is recorded among the SRR# 3, and the different pieces of information unit that above-mentioned like this data recording operation can be avoided being caused by the logical overwrite order is recorded among the single SRR.
Then, if the user wants in CD user data again, a new SRR# 4 is assigned to CD, and user data is recorded among the SRR# 4 like this.
Above-mentioned logical overwrite operation generates from CD drive.In more detail, though the actual BD-R that is equal to of CD, application program or main frame can freely be applied to BD-R, are BD-RE as BD-R, and irrelevant with the prerecorded zone of BD-R.
Therefore, if the actuating logic rewrite operation, application program or main frame do not identify: because the generation of above-mentioned logical overwrite operation, next writable area (NWA) is modified and is another zone.
Therefore, file system can be handled wherein owing to carry out rewrite operation and make NWA be modified the particular case into another NWA.In more detail, if file system wishes to carry out data recording operation, the positional information of its inquiry next writable area of CD drive (NWA), and allow data to be recorded among the NWA corresponding to the change of this positional information.
Simultaneously, the SRR of late allocation (being SRR# 3 and SRR#4) is formed on the next door of subregion of the SRR# 2 of the user data that is not used in original allocation.
Though second preferred embodiment of the present invention exemplarily illustrates when the particular case that insufficient alternative recording areas is provided during the actuating logic rewrite operation in the SRR that is comprising file system (FS) data, for the those skilled in the art, obviously logical overwrite operation can be performed in its All Ranges is full of the SRR that closes of file system (FS) data.
Fig. 5 illustrates the method for logical overwrite data in BD-R according to the 3rd preferred embodiment of the present invention.
Just from Fig. 5 finding, according to the 3rd preferred embodiment of the present invention, when the file system data district of SRR# 1 was full of data so that SRR# 1 and is closed, the record order that is associated with new file system data was applied to pent SRR# 1.
Like this, if the record order that is associated with prerecorded zone is applied to SRR# 1, the data that be recorded in the prerecorded zone (being SRR#1) are recorded in the nearest NWA of prerecorded zone (being SRR#1), rather than are recorded in the prerecorded zone (being SRR#1).
Therefore, data are recorded in and comprise among the SRR# 3 that closes on NWA most, rather than among the SRR#1.In this case, because SRR# 3 represents wherein to record the zone of file system data, the data identical with SRR# 1 are recorded among the SRR# 3, and data instant is recorded among the NWA of SRR# 3 like this, and does not close SRR.
Be associated with the CD that wherein carry out to substitute recording operation, hereinafter will be with reference to a kind of method that is used at the SRR that closes or is comprising logical overwrite data among the SRR that the not enough user data that substitutes posting field is recorded in it of figure 6 explanations.
Fig. 6 illustrates the method for logical overwrite data in BD-R according to four preferred embodiment of the invention.
As Fig. 6 finding, if comprise that the SRR# 2 of user data is full of data so that it is closed, if perhaps SRR# 2 has not enough alternative posting field, the record order of new data can be sent to SRR# 2.
In this case, the data that be recorded in SRR# 2 are recorded among the NWA that closes on most.In other words, data are recorded among the NWA that occurs among the SRR# 3 that closes on SRR# 2 most.
In this case, log file system data among the SRR#3.Therefore, if preferred embodiment actuating logic rewrite operation in SRR# 3 as described above then is mixed with different data cells in SRR#3.In more detail, wish that identical data are recorded among the single SRR, but since the generation of logical overwrite operation, the different data cell of physical presence in single SRR.
In order to solve the above problems, wish that user data is sequentially recorded.In more detail, though can be in the All Ranges actuating logic rewrite operation of BD-R, usually for the user data that generates by file system execution sequence recording operation only.
CD according to the present invention comprises " open SRR tabulation " territory of sequence of information recording interval information (SRRI) head that is associated with open SRR, can utilize " open SRR tabulation " territory actuating logic rewrite operation on the SRR that closes of storaging user data easily like this, and utilize " open SRR tabulation " can avoid different data cells to be recorded among the single SRR.Hereinafter will be described in detail about this point with reference to figure 7.
Fig. 7 is that expression is according to the structural drawing based on the SRRI of SRM method among the BD-R of being used in of the present invention.In more detail, Fig. 7 shows a kind of logical overwrite method according to the 5th preferred embodiment of the present invention.
With reference to figure 7, SRRI represents to be recorded in the information among the TDMA of CD.SRRI comprises " tabulation of SRR input item " territory and " SRRI termination " territory.
" SRRI head " territory comprises ID (sign) information of " SRRI identifier=' SR ' " territory as expression SRRI." SRRI head " territory also comprises " SRR imports item number " territory, " open SRR number " territory and " open SRR sequence number tabulation " territory.
The information of expression SRR input item number is recorded in " SRR imports item number " territory.The information of the open SRR number of expression is recorded in " open SRR number " territory.The information of the open SRR sequence number tabulation of expression is recorded in " open SRR sequence number tabulation " territory.
The information that is associated with open SRR sequence number tabulation is recorded in " open SRR sequence number tabulation " territory.Just as shown in Figure 7, all be assigned with two bytes, made each SRR sequence number field record data therein from each of 16 open SRR sequence number field of first open SRR sequence number field to the 16 open SRR sequence number field.
In this case, aforesaid SRR sequence number successively decreased with numeral the order distribute.If the sequence number of the SRRs that is assigned with is less than 16, data 0 are recorded in the single untapped open SRR sequence number field.Therefore, CD drive is searched for to substitute and can be write down SRR by inquiry " open SRR sequence number tabulation " territory.
According to the present invention, when utilizing above-mentioned SRRI header information in pent SRR during the actuating logic rewrite operation, logical overwrite operation is performed avoiding different data cells to occur in single SRR, and hereinafter will be described in detail with reference to figure 8 about this point.
Fig. 8 illustrates the method for logical overwrite data in BD-R according to the 5th preferred embodiment of the present invention.
With reference to figure 8, if CD drive is wished actuating logic rewrite operation on prerecord SRR or the SRR that closes by user request, pent SRR sequence number is recorded among the NWA of open SRR of the remainder that is obtained divided by open SRR number corresponding to the SRR sequence number of closing.
For example, as shown in Figure 8, suppose the SRR that closes be the the 0th, the 1st, the 2nd and 3SRR (be SRR0, SRR1, SRR2 and SRR3), file system data is recorded among the aforesaid SRR0 and SRR2 that closes, and user data is recorded among the aforesaid SRR1 and SRR3 that closes.If open SRR is the 4th and 5SRR, " open SRR sequence number tabulation " territory storage " open SRR tabulation [0]=4 " information and " open SRR tabulation [1]=5 " information.
