So far, the present invention's exemplary configurations that can be applied in its recording medium is described.With reference to Fig. 1, after being initialized as the DM on-mode of blank panel 1, the DMA of dish is empty and TDMA enters the state 2 that TDMA therein can be updated.Renewal indication TDMI in TDMA of TDMA is updated.Such renewal is carried out with the booking situation unit of being operating as, and according to an aspect of the present invention, described unit can be one and write back checking unit or a plurality of back checking unit or ejection unit of writing that piece is recorded then and is verified in writing back checking unit.Here, piece refers to error correcting code (ECC) unit that is recorded in the dish.Yet, should be appreciated that, except being that other update methods can be used and/or carry out the unit with the recording operation.
When by drive assembly dish being carried out defect management, data are recorded in the dish 1 of state 2.Then, according to defect management data recording simultaneously, the TDMA shown in Fig. 4 remains on the state 3 that TDMI wherein is updated.In the dish 1 of user mode 3, if in the spare area, produce any change, to coil 1 so and reinitialized, the size information of the spare area of TDMI is changed, and the size information of the change of spare area is recorded among the TDMA, and DMA remains empty.If the spare area that distributes during the dish initialization is fully consumed and the spare area needs are extended, if perhaps user data area lacks zone and the spare area that data will be written into and need be reduced, the size information of spare area is changed (state 4) between the operating period of dish 1 so.The TDDS#i that comprises such change is recorded among the TDMA.Even after the size of spare area is changed, by drive assembly data when coiling the execution defect management also are being recorded in the dish 1, and TDMA is updated (state 5).
With defect management data recording simultaneously during, dish 1 can be reinitialized DM and close pattern.When dish 1 is reinitialized DM and closes pattern, for the compatibility of re-writable recording medium, the final TDDS and the TDFL information that are recorded among the TDMA are recorded among the DMA as DDS and DFL information, and TDMA to be changed be that DM closes pattern.In other words, be set to make renewal among the TDDS that DM pass pattern comes to show in Fig. 7, and the TDDS#n of the final updated in TDMA and TDFL#n are replicated and are recorded in (state 11 to 13) among the DMA by the DM pattern.
Particularly, after just being turned to DM pass pattern again, the DMA of dish 1 is filled and TDMA enters the state 11 that TDMA therein can be updated.Because being changed, the DM pattern is that DM closes pattern, so do not having under the situation of defect management data be recorded and TDMA is updated (state 12).Because defect management is not performed, so the renewal of TDMA relates generally to TDDS#i and SBM#i.Yet if be included among the TDFL#i with the irrelevant content of defect management, TDFL#i also can be updated so.Be used by this way although coil 1, finally determined as fruit tray 1, TDMA is filled and gets the hang of 13 so, and final definite sign is set up (state 13) in TDMA in described state 13.
Data be recorded in the dish of state 5 and by drive assembly to coil 1 carry out defect management in, finally determined as fruit tray, in TDMA, finally determine so to indicate to be configured to prevent after finally determining, coil and be used, and the TDMI of the final updated in TDMA (that is, TDDS#m and TDFL#m) fills DMA and is used as final DMI (state 6).With reference to the embodiment among Fig. 7, finally in TDDS determine that sign is set to " 1 " and finally determines to indicate, and TDDS is recorded among the TDMA and is finally determined with display disc.In addition, be updated in TDMA in order to prevent TDMI, predetermined bit (for example, " FFh ") can be filled in the remaining area of the TDMA that does not wherein have record data.As a result, TDMA is filled.
DM closes pattern
The life-span of closing the write-once optical medium of pattern according to DM is presented in the bottom of Fig. 1.To be used according to DM pass pattern if determine dish 1, blank panel 1 is initialized to DM and closes pattern so.It is empty being initialized as the DMA that DM closes the dish of pattern, and TDMA enters the state 7 that TDMA therein can be updated.The end position information that during the dish initialization, in TDMA, comprises the start position information and the user data area of user data area as the TDDS of initial information record.The size information of the size information of spare area # 1 and spare area # 2 is registered as " 0 ".In addition, the DM pattern is set to DM and closes pattern.
Because defect management is not performed during data recording, so TDDS and SBM are mainly upgraded in TDMA.Because do not carry out defect management, so the detailed data of the TDDS that uses under the pattern of DM pass can be different.For TDDS and SBM and TDDS that uses under the DM on-mode and the SBM differentiation that will use under the pattern of DM pass, the TDDS and the SBM that use under the pattern of DM pass are called as records management information.
Under the pattern of DM pass, data are recorded in the dish 1 under the situation of not carrying out defect management by drive assembly, and TDMA remains on the state 8 that TDMA wherein can be updated.When dish 1 quilt was finally determined, final definite sign was configured to prevent to coil 1 and is used (state 9) after finally determining in TDMA.In addition, the final TDMI that upgrades in TDMA (that is records management information) fills DMA and is used as final DMI (state 9).Final definite dish 1 has indicates final final definite state that is set up among TDDS in being recorded in TDMA or the SBM that indicates of determining therein, describedly in TDMA, be recorded among the DMA as DMI by the TDDS of final updated and SBM, and the value that equates with " FFh " is recorded in remaining area that SBM can be recorded (promptly, the remaining area of TDMA) in, is recorded in the remaining area of TDMA to prevent data.
Hereinafter, can use the recording/reproducing apparatus of above-mentioned dish to describe with reference to Figure 11.Figure 11 is the schematic block diagram according to recording/reproducing apparatus of the present invention.With reference to Figure 11, this recording/reproducing apparatus comprises record/reading unit 21 and control module 23.Record/reading unit 21 comprises the pick-up that is used for the data on dish 22 at dish 22 identifying recording layers and/or reading and recording, and described dish 22 is optical record mediums according to an aspect of the present invention.Control module 23 according to the one side controlling recording/reading unit 21 of predetermined file system with at dish 22 identifying recording layers with from coiling 22 reading of data.Particularly, according to the present invention, control module 23 determines whether to carry out defect management and according to the initializes dish of determining 22 during data recording when blank panel loads in record/reading unit 21.In addition, control module 23 is coiling in 22 the data recompile according to the controlling recording/reading unit of determining as a result 21 of following detailed description.
Control module comprises main frame I/F 24, DSP 25, RF AMP 26, servo-drive system 27 and system controller 28.During data recording, main frame I/F 24 receives the predetermined recording order from main frame 29, and this predetermined recording order is sent to system controller 28.System controller 28 control DSP 25 and servo-drive system 27 are to carry out the predetermined recording order that receives from main frame I/F 24.DSP 25 adds from the data that main frame I/F 24 receives the additional data of for example parity checking to be used for error correction to, generates error correction block (that is, the ECC piece) by data being carried out error correcting codes (ECC) coding, and modulates the ECC piece in a predetermined manner.RF AMP 26 will be converted to the RF signal from the data of DSP 25 outputs.Record/reading unit 21 comprises the pick-up that is used for writing down from the RF signal of RF AMP 26 transmissions on dish 22.Servo-drive system 27 receives the required order of servocontrol from system controller 28, and the pick-up of record/reading unit 21 is carried out servocontrol.
Particularly, according to an aspect of the present invention, system controller 28 is determined with the DM on-mode still with DM pass pattern use dish 22.So really, definiteness is shown in data and is recorded in whether defect management will be performed when coiling in 22.Although be not all to be required aspect all of the present invention, system controller 28 detects from user's input or detects input from drive manufacturers, and uses the input that detects to determine that dish 22 is in the DM on-mode and still is in DM pass pattern.Yet, should be appreciated that input can differently be received.
If system controller 28 determines that with DM on-mode use dish 22 system controller 28 controlling recording/reading unit 21 is carried out defect management when data are recorded on the dish 22 so.In other words, system controller 28 controlling recording/reading unit 21 writes down replace block with the predetermined unit of being operating as in the spare area of recording medium 22, and upgrades about the information of defective in the TDMA of recording medium and be used for the TDMI of the management of defective with the predetermined unit of being operating as, described replace block replacement produces the defect block of user data area of the recording medium of defective therein.As needs, system controller 28 also changes the size of spare area when dish 22 is used with the DM on-mode.System controller 28 controlling recording/reading unit 21 writes down the information about the size of the spare area that changes (if the words that have) in TDMA.
Even dish 22 is set to the DM on-mode during the dish initialization, system controller 28 also can will coil 22 DM on-mode and be converted to DM pass pattern when dish 22 uses with the DM on-mode.For such conversion, system controller 28 will coil 22 and be reinitialized to DM pass pattern, and controlling recording/reading unit 21 is not recorded in data in the dish 22 under having the situation of defect management.In other words, during reinitializing, system controller 28 controlling recording/reading unit 21 writes down the information that display disc 22 uses with DM pass pattern in TDMA, and will be recorded among the DMA that provides in the recording medium 22 by the TDMI of final updated in TDMA.
When the dish 22 that uses is by this way finally determined, system controller 28 controlling recording/reading unit 21 writes down final determine final of indication recording medium 22 quilts and determines to indicate in TDMA, to in TDMA, be recorded in the disc management area (DMA) that provides in the recording medium 22 as DMI by the TDMI of final updated, and fill the remaining area of the TDMA that is not written into tentation data.
When system controller 28 determined to coil 22 with the pattern use of DM pass, its controlling recording/reading unit 21 was not recorded in data in the dish 22 under having the situation of defect management.In other words, system controller 28 controlling recording/reading unit 21 data is provided in the user data area that provides in the dish 21 with the predetermined unit of being operating as, and upgrades records management information according to such being recorded in the temporary defect management area that provides in the dish 21.In addition, in the mode identical with the DM on-mode, when dish 22 is finally determined, system controller 28 controlling recording/reading unit 22 writes down display disc 22 by final final definite sign of determining in TDMA, to in TDMA, be recorded in the disc management area that provides in the dish 22 by the TDMI of final updated, and fill the remaining area of the TDMA that is not written into tentation data.
At reproduction period, main frame I/F 24 receives from main frame 29 and reproduces order.System controller 28 is carried out and is reproduced required initialization.Record/reading unit 21 projects laser beam on the dish 22 and exports by receiving from coiling the light signal that 22 laser light reflected bundles obtain.RF AMP 26 will be converted to the RF signal from the light signal of record/reading unit 21 outputs, will offer DSP 25 from the modulation signal that the RF signal obtains, and will offer servo-drive system 27 from the servosignal that is used to control that the RF signal obtains.Servo-drive system 27 receives servosignal and receives the required order of servocontrol from system controller 28 from RF AMP 26, and servo-drive system 27 execution are to the servocontrol of pick-up.Main frame I/F 24 will send to main frame 29 from the data that DSP 25 receives.
Particularly, according to an aspect of the present invention, system controller 28 controlling recording/reading unit 21 is from the TDMA read mode information that provides 22 is provided, and based on these data of information reading and recording in the data field that read.When the pattern information that reads is the DM on-mode, system controller 28 controlling recording/reading unit 21 reads the information and the defect management information about defective of final updated from TDMA, if and indicated recording medium 22 to be read from TDMA by final final definite sign of determining, system controller 28 controlling recording/reading unit 21 would be from information and the defect management information about defective that the DMA that provides 28 reads final updated is provided so.
When the pattern information that reads was DM pass pattern, system controller 28 controlling recording/reading unit 21 read final records management information from TDMA.If indication recording medium 22 is determined that by final determine final sign is read from TDMA, system controller 28 controlling recording/reading unit 21 reads the records management information of final updated from the DMA that provides 22 is provided so.
Figure 12 A uses the process flow diagram of the method for once writing recording medium to what Figure 12 E was expression according to the embodiment of the invention with DM on-mode or DM pass pattern.
Although be not all to be required in aspect all, Figure 12 A also can be embodied as computer-readable software to the method among Figure 12 E.In addition, should be appreciated that if controller 28 is multi-purpose computer or special purpose computer, the method for Figure 12 A in Figure 12 E can read computer-readable medium by controller 28 and realize with retrieval Methods for Coding on computer-readable medium so.In case once writing recording medium 22 is loaded in the drive system, then the system controller 28 of drive system the information in the dish 22 of loading of being stored in by use discern loading dish 22 (promptly, the dish 22 that loads is any type), whether the dish 22 whether dish 22 of loading can write down and load is used.If the once writing recording medium that loads in operation 10 is identified as blank panel 22, system controller 28 is carried out initialization process according to user's the order or the intention of drive manufacturers so.
In operation 15, system controller 28 determines whether to carry out the DM pattern according to the intention of user or drive manufacturers.When system controller 28 was determined not carry out defect management and selected DM to close pattern according to the intention of user or drive manufacturers, initialization information was recorded in the dish 22 in operation 20, and handles the A that forwards among Figure 12 E.Because defect management is not performed and the spare area is not assigned with under the pattern of DM pass, thus be registered as " 0 " among the TDDS of the size information of spare area in being recorded in TDMA, and the DM pattern is set to DM and closes pattern.
When system controller 28 is selected the DM on-mode, the part that it gives the data field of dish 22 with spare area allocation, and in dish, write down by the defect management of drive assembly required information and initialization information (operation 30).More particularly, initialization information is included among TDDS# 0, SBM# 0 and the TDFL# 0, is recorded among the TDMA then.With reference to as shown in Figure 7 embodiment, TDDS# 0 start position information and end position information, the TDFL pointer of the size of the spare area that provides in the data field and positional information, user data area is provided and is set to the DM pattern of DM on-mode.Be initialised in case coil 22, then coil 22 DMA and be empty and TDMA and enter the state that TDMA therein can be updated.
After initialization, the record order of record/reading unit 21 and control module 23 response main frames comes executive logging (operation 40) by the back proof procedure that writes that is used for defect management.Hereinafter, the back proof procedure that writes of operation 40 is described in more detail with reference to Figure 12 B.In operation 41, user data is recorded in the user area with the unit that proof procedure after writing is performed.In operation 42, the data of record are verified the part that produces defective with discovery therein, and the replace block of replacement defect block is recorded in the spare area.In operation 43, be generated and be stored in the storer about the information of defective.In operation 44, determine whether the predetermined recording operation is finished.If the predetermined recording operation is not finished, handle to forward operation 41 to and write down being repeated so.If the predetermined recording operation is finished, handle forwarding the operation 50 that figure shows and show in detail to so in 12A in Figure 12 C.
In operation 50, defect information and defect management information are updated with the unit of being operating as.The renewal process of operation 50 is described in detail with reference to Figure 12 C.In operation 51, the information about defective of storing in the storer is read into.In operation 52, comprise that the defect list about the information of defective is generated.In operation 53, the defect list of generation is recorded among the TDMA as TDFL#i, and wherein i is corresponding to the quantity of recording operation.In operation 54, TDDS#i and SBM#i are recorded among the TDMA.It is above-mentioned that proof procedure comes the operation 40 of executive logging and the example of the operation 50 of upgrading defect information and defect management information to describe with reference to Figure 13 by writing afterwards.
Figure 13 is the reference diagram that is used to explain the processing of defect management according to an aspect of the present invention.Here, data processing unit can be divided into the sector and bunch.The sector is the minimum data unit that can manage by the file system or the application program of computing machine.Bunch be the minimum data unit that at every turn can physically be recorded in the dish.Usually, at least one sector is formed one bunch.
The sector comprises physical sector and logic sector.Physical sector is the space of the dish that is recorded with the corresponding data in sector therein.Be used to find the address of physical sector to be called physical sector number (PSN).Logic sector is the sector location that is used at file system or application program management data.Similarly, logic sector number (LSN) is assigned to logic sector.For example show among Figure 11 with data recording to the dish or from the dish reading of data data recording/reproducing apparatus, by using PSN to find the position that data will be recorded or reproduce on dish, yet, being used for record or reproduction data computing machine or application program is the unit management total data with the logic sector, and by using LSN to find the position of data.By using whether produce the fact of defective and the position that data recording begins, the contact between LSN and the PSN is converted.
With reference to Figure 13, user data area and spare area are shown.In user data area and spare area, a plurality of PSN are arranged by the physical sector (not shown) of sequentially distributing to it.LSN is assigned at least one physical sector unit.Yet except the defect area of the user data area that produces defective therein, LSN is assigned to the replacement district of spare area.As a result, though physical sector is identical with logic sector in size, if produce defect area, PSN and LSN dissimilate so.
According to sequential recordng mode or recorded at random pattern, user data is recorded in the user data area.Under sequential recordng mode, user data is by record sequentially and continuously.Under the recorded at random pattern, user data does not need by record continuously, but by record randomly.(1) writes the cellular zone that the back proof procedure is performed therein to (7) indication.Data recording and/or reproducer record the user data in the cellular zone (1), and starting position and checking user data that data recording and/or reproducer return cellular zone (1) still are the generation defective by normally writing down.If produce bunch being found of defective therein, this bunch is identified as defect cluster and is designated as defect area (that is defective #1) so.In addition, data recording and/or reproducer rewrite the data that have been recorded among the defective #1 in the spare area.The part of the spare area that is rewritten of user data is designated as and replaces #1 therein.Next, in recording the user data in cellular zone (2) after, data recording and/or reproducer return cellular zone (2) the starting position and the checking user data by normally the record still be the generation defective.If at least one produces bunch being found of defective therein, this bunch is designated as defective #2 so.With with above same mode, to replace #2 accordingly designated with defective #2.In addition, in cellular zone (3), defect area (that is defective #3) and with defective #3 to replace #3 accordingly designated.In cellular zone (4), do not find to produce the part of defective, and do not have defect area.
After the record and checking finished cellular zone (4), if expectation (for example stops recording operation # 1, if the record that the user presses ejector button or distributes to the user data of recording operation # 1 is done), so data recording and/or reproducer will defective # 1 that cellular zone (1) produces in the cellular zone (4) be recorded in to the positional information of defective # 3 TDFL temporary defect information (that is, TDFL#1) in.In addition, the management information that is used for the management of TDFL# 1 is recorded in TDMA as TDDS# 1.
In case recording operation # 1 begins, data are to be stored in (5) to (7) to the identical mode of cellular zone (4) with cellular zone (1) so.Therefore, defective # 4 and defective #5 and its corresponding replacement # 4 and replacement #5 are designated.Defective # 1, #2, #3 and #4 are single defect block, its each comprise a defective.Defective #5 is the continuous defect piece, and its continuous piece comprises defective.Replacing #5 is the continuous replace block of replacing defective #5.Piece is physics or logical record unit and can changes.If recording operation # 1 is finished in expectation, the recording unit record comprises that temporary defect information # 2 about the information of defective # 4 and defective #5 (that is, TDFL#2), and is recorded in the information of cumulative record among the temporary defect information # 1 so.Similarly, the defect management information that is used for the management of TDFL# 2 is recorded in TDMA as TDDS# 2.
With reference to Figure 12 A, in operation 60, when spare area deficiency and spare area need extended or user data area is not enough and spare area need be reduced the time, system controller 28 determines whether to change the spare area size.If system controller 28 determines to change the spare area size, in operation 70, the information of reinitializing is recorded in the dish 22 and handles and forwards operation 40 to so.In other words, the size information of the change of spare area is included among the TDDS and TDDS is recorded among the TDMA.
Next, system controller 28 determines whether that dish 22 is reinitialized to DM closes pattern (operation 80).If system controller 28 determines to reinitialize dish 22, in operation 81, the information of reinitializing is recorded in the dish 22 and handles and forwards the A that shows among Figure 12 E to so.Be reinitialized DM as fruit tray 22 and close pattern, the DM on-mode that is provided with in TDDS so is converted into DM and closes pattern upgrading TDDS, and for the compatibility of rewritable media, the TDDS of final updated and TDFL are recorded among the DMA in TDMA.
Next, system controller 28 determines whether the final dish 22 (operation 90) of determining.If system controller 28 determines finally not determine dish 22, processing forwards operation 40 to and is performed by writing back checking process record so.If system controller 28 is determined the final dish of determining, system controller 28 will determine finally that information is recorded in (operation 100) in the dish so.
The operation 100 of the final definite information of record is described with reference to Figure 12 D in dish.In operation 101, system controller 28 determines that finally sign is set to " 1 " in TDDS or SBM, and in operation 102, system controller 28 is recorded in particular value in whole remaining areas of the SBM that is not written into.According to the embodiment that shows, particular value can be recorded in the whole remaining areas of the TDMA that is not written into.In operation 103, the TDDS and the TDFL that are recorded in the final updated among the TDMA fill DMA.
Next, the operation when selecting DM to close pattern is described with reference to Figure 12 E.In operation 110, system controller 28 controlling recording/reading unit 21 is not recorded in data in the dish 22 under having the situation of defect management.In operation 120, system controller 28 upgrades TDMA.Because defect management is not performed, so the renewal in TDMA mainly is TDDS and SDM.In operation 130, system controller 28 determines whether the final dish 22 of determining.
If system controller 28 is determined the final dish 22 of determining, determine that so finally information is recorded in (operation 140) among the DMA.Final definite recording of information is identical with above description with reference to Figure 12 D elaboration in operation 140, and no longer sets forth.If system controller 28 determines finally not determine dish 22, handle forwarding operation 110 to so, and record is performed under the situation of defect management not having.
As mentioned above, according to an aspect of the present invention, recording medium can optionally be used, and according to this selection defect management is carried out or do not carried out to recording medium.In addition, even in to recording medium execution defect management, after the service recorder medium, can not have to use this recording medium under the situation of defect management yet.In addition, recording medium can use with rewritable media compatiblely.In addition, recording medium can be CD-R, DVD-R, Blu-ray disc, Advanced Optical Disc (AOD), rewritable media, magnetic medium and/or a magnet-optical medium of carrying out defect management.
Described recording/reproducing method can be implemented as the computer-readable code in the computer readable recording medium storing program for performing.Computer readable recording medium storing program for performing comprises the various recording units that can be stored in by the data of computer system reads wherein.Such computer readable recording medium storing program for performing is ROM, RAM, CD-ROM, tape, floppy disk and optical data memories, and through the transmission of internet (for example, carrier wave).Computer readable recording medium storing program for performing can be distributed in the computer system that is connected to network, and can be stored according to the form of computer-readable code and operate.The function program, code and the code segment that are used to realize described recording/reproducing method can easily be explained by this area programming technique personnel.
