According to many aspects of the present invention, may be implemented as independent recording unit at the recording/reproducing apparatus shown in Fig. 9, the part of independent reproducer, single record and reproducer, autonomous device and/or computer system.
To exemplary initialize method and the exemplary heavy initial method of carrying out by according to the recording/reproducing apparatus of the embodiment of the invention be described with reference to Figure 10 and Figure 11 below.
Figure 10 is the process flow diagram according to the initial method of the embodiment of the invention.With reference to Figure 10, in operation steps 1010, blank panel 100 is written in the drive system.In operation steps 1020, the system controller 10 that is included in the drive system receives initialization command through main frame I/F20 from main frame 3.System controller 10 is assigned the size of spare area with definite spare area in the data field of dish 100 in operation steps 1030, and the UDA that assignment is used for user data in the data field in operation steps 1040 is to confirm start address and the end address of UDA.The spare area can be assigned or can be assigned with predetermined size by drive maker by main frame 3.
In operation steps 1050, system controller 10 control write/read unit 2 and servo control mechanism 50 are recorded among the DMA in the Lead-In Area that is included in dish 100 with initial DFL will comprise about the information of the assignment of spare area with about the DDS of the information of the assignment of UDA.The initialization information that is recorded among the DMA is described in detail with reference to Fig. 4.
In operation steps 1060, system controller 10 control write/read unit 2 and servo control mechanism 50 are with will be about being recorded among the ACA in the Lead-In Area that is included in dish 100 by the ACD of the function of drive system identification.The access control information that is recorded among the ACA is described in detail with reference to Fig. 5.
In operation steps 1070, system controller 10 control write/read unit 2 and servo control mechanism 50 are filled in remaining not recording areas among the ACA of dish 100 with the predetermined value such as 00h or FFh.
Figure 11 is the process flow diagram according to the heavy initial method of the embodiment of the invention.With reference to Figure 11, in operation steps 1110, the dish 100 that has been used is written in the drive system.Then; The information that is included in the operation that the ignorant function actuator of function that system controller 10 identification records in the drive system know for system controller 10 in the dma information of dish on 100 and regulation and system controller 10 system must carry out (that is, ACD).Then, in operation steps 1120, system controller 10 receives heavy initialization command through main frame I/F20 from main frame 3.
In operation steps 1130, system controller 10 control write/read unit 2 are with DMA and the information in ACA of reading and recording in the Lead-In Area that is included in dish 100, and take out this information.The information that is recorded among the DMA can be the write-protect sign, but and the information among the ACA of being recorded in can be the information that is included in the public information of ACD about recordability or form voltinism.
In operation steps 1140, system controller 10 confirms whether allow heavily initialization from the information that DMA and ACA read.For example, if the write-protect sign that reads from DMA is " 1 ", then forbid the write operation to coiling 100, therefore heavily initialization can not be performed, thereby error message is sent out in operation steps 1190.But the public information that is recorded in the ACD among the ACA comprises form voltinism information and about coiling the recordability/reproducibility information in 100 subarea.If but form voltinism information and recordability/reproducibility information does not allow to coil 100 format or to coiling any one write operation of 100 subregion, then heavily initialization can not be performed, thereby error message is sent out in operation steps 1190.Therefore, system controller 10 confirms based on the information that reads from DMA and ACA whether dish 100 is recordable.
If the write-protect sign is set to " 1 " or the public information of ACD do not allow format or write operation, then system controller 10 confirms that dish 100 can not be by heavily initialization, and in operation steps 1190, sends error messages through main frame I/F20 to main frame 3.Yet, if being set to the public information of " 1 " and ACD, the write-protect sign allows format and write operation, system controller 10 definite heavily initialization dishes 100 also begin heavily initialization dish 100.
Simultaneously; Do not allow heavy initialized value and have when allowing heavy initialized value when having about ACD by the unrecognizable function of drive system about ACD by the discernible function of drive system; Because the value about the ACD of discernible function can be updated; So the value about the ACD of discernible function can be changed into the heavy initialized value of permission in response to the heavy initialized request of user, then, can confirm to begin to coil 100 heavily initialization.
If allow heavily initialization; Then in operation steps 1150; System controller 10 is assigned the size of spare area with definite spare area in the data field of dish 100, and the UDA that assignment is used for user data in the data field is to confirm start address and the end address of UDA.
In operation steps 1160; System controller 10 control write/read unit 2 are included in the DMA in the Lead-In Area on the dish 100 to remove (clear), and control write/read unit 2 and servo control mechanism 50 with initial DFL with comprise that definite information is that the DDS of spare area assignment information and UDA assignment information is recorded among the DMA.Be recorded among the DMA after being eliminated though described initialization information, in fact, because dish 100 is rewritable types, so the initialization information that is recorded among the DMA is updated.Though in Figure 11, show, be recorded in being used for management accounts and should being eliminated in the predetermined portions of UDA at the filesystem information of the data of UDA.
In operation steps 1170; System controller 10 control write/read unit 2 are with the ACA in the Lead-In Area on the clear disk 100, and control write/read unit 2 and servo control mechanism 50 are with among the ACA that will be recorded in the Lead-In Area on the dish 100 about the ACD of the discernible function of drive system.
In operation steps 1180, system controller 10 control write/read unit 2 and servo control mechanism 50 are with such as remaining not recording areas among the ACA in the Lead-In Area on the predetermined value filling dish 100 of 00h or FFh.Operation steps 1180 is performed with indication does not have more ACD and makes not that recording areas can be used afterwards in ACA.
Below description relate to when management during about the status information of the recordability of the ACD piece among the ACA or defective during the heavily initialization of dish the method for renewal ACD block state information.When the status information of each the ACD piece that is included in the ACA that is used for writing down ACD is recorded among the DDS and during by management, the ACD piece can be by management effectively.Status information can indicate ACD can be recorded in the ACD piece, and indication ACD piece is defective or stores invalid ACD, and indication ACD piece is stored effective ACD, and but indication ACD piece is stored effective ACD had the defective that takes place at reproduction period.Being recorded in ACD piece among the ACA with physics mode has drive system can to discern the ACD piece from it is the ACD_ID about what function.When dish was written in the drive system, drive system was surveyed the position of effective ACD piece based on the ACD block state information among the DDS that is included among the DMA that is recorded on the dish, and reproduced this effective ACD piece.
If the ACD block state information of before heavy initialization, indicating the ACD piece to have effective ACD is included among the DDS, then the ACD piece is good.After heavy initialization,, do not have effective ACD and can be used to write down ACD so the ACD block state information need be changed with indication ACD piece because the ACD that is recorded in the ACD piece is dispensable.Heavily be not changed during the initialization if be included in the ACD block state information that being used among the DDS indicate the ACD piece to have effective ACD, then drive system will reproduce the ACD piece based on this ACD block state information.Therefore, when heavy initialization dish, must upgrade this ACD block state information.In addition, owing to be included in the information no longer valid after heavy initialization in the ACD piece, so if the ACD block state information is not changed, then drive system can have trouble owing to the incorrect information that obtains from the ACD piece.Therefore, except change is included in the ACD block state information among the DDS, the whole ACD piece among the ACA or only the ACD_ID of ACD piece need to be override to eliminate with the mode of physics by value with for example " 00h " or " FFh ".When ACD_ID had value " 00 " or " FF ", the current ACD of ACD piece was not effectively, and this ACD piece can be used to write down other ACD.Because " 00h " or " FFh " is recorded in the ACD piece when removing the ACD piece, so the ACD_ID of ACD piece becomes value " 00 " or " FF ".
Say briefly; During heavy initialization; Effective ACD piece among the ACA on the dish is override by the value with for example " 00h " or " FFh ", and the corresponding ACD block state information that is included among the DDS on the dish is changed to indicate the ACD piece not have effective ACD and can be used to write down other ACD.
Figure 12 is illustrated in another example of the detailed structure of the DMA#1115 that shows among Fig. 3.With reference to Figure 12, DDS410 is the zone of indicator management information therein.Spare area size information 411, UDA start and end address information 412 and ACD status information 413 are recorded among the DDS410.ACD status information 413 comprises each recordability or the status information of defective that is recorded in ACD piece among the ACA about ACD therein.With reference to Figure 12, the length of ACD block state information is 2.
Figure 13 representes to be included in the ACD block state information in the ACD status information, such as the example of the block state information that in Figure 12, shows.With reference to Figure 13, the state of each ACD piece is to indicate 2 of one of four kinds of states, and promptly " 00 ", " 01 ", " 10 " or " 11 " are represented.Multidigit " 00 " indication ACD piece can be used for writing down ACD.Multidigit " 01 " indication ACD piece is defective.More particularly, multidigit " 01 " indication ACD piece when ACD is recorded among the ACA is detected as defectiveness or indicates the ACD piece to have invalid ACD.Multidigit " 10 " indication ACD piece has effective ACD, but when ACA reproduces, is detected as defectiveness when the ACD quilt.Multidigit " 11 " indication ACD piece has effective ACD.
Figure 14 A is the diagrammatic sketch that is used to explain the renewal of the ACD status information when dish is by heavy initialization according to the present invention to 15B.Figure 14 A and 14B are illustrated respectively in ACD piece and the example of ACD status information before the heavily initialization.Figure 15 A and 15B are illustrated respectively in ACD piece and the example of ACD status information after the heavily initialization.
With reference to Figure 14 A, before heavy initialization, ACA comprises five ACD pieces: ACD piece #1 has effective ACD; ACD piece #2 has defective ACD; ACD piece #3 has effective ACD; ACD piece #4 does not have data or has one of " 00 " and " FF " value as ACD_ID; With ACD piece #5, have effective ACD and have defective that reproduction period takes place (below, be called the defective when reproducing).ACD_ID indication with value " 00 " or " FF ": though data have been recorded in the ACD piece, because the data in this ACD piece are not effectively, ACD can be recorded in this ACD piece later on.
Figure 14 B representes the status information to ACD piece #5 about the ACD piece #1 that in Figure 14 A, shows.With reference to Figure 14 B, multidigit " 11 " is registered as ACD piece #1 status information and has effective ACD with indication ACD piece #1.It is defective with indication ACD piece #2 that multidigit " 01 " is registered as ACD piece #2 status information.Multidigit " 11 " is registered as ACD piece #3 status information and has effective ACD with indication ACD piece #3.Multidigit " 00 " is registered as ACD piece #4 status information to indicate: because ACD piece #4 does not have the data that are recorded in wherein or do not have invalid data, so ACD piece #4 can be used for writing down ACD.Defective when multidigit " 10 " is registered as ACD piece #5 status information and has effective ACD and reproduce with indication ACD piece #5.
ACD piece that in Figure 14 A and 14B, shows and ACD status information are changed through the heavily initialization of dish, as shown in Figure 15 A and the 15B.
With reference to Figure 15 A; After heavy initialization; Only defective ACD piece #2 remains on the state before the heavily initialization; But other ACD piece, promptly effectively the ACD piece, have " 00 " or " FF " as the ACD piece of the value of ACD_ID and the ACD piece with the defective when reproducing become and have " 00 " or " FF " value as their ACD_ID, thereby these ACD pieces can heavily be used after the initialization.Even before heavy initialization, not having the not record block of data is heavily still keeping intact after the initialization.
Figure 15 B representes the status information to ACD piece #5 about the ACD piece #1 that in Figure 15 A, shows.With reference to Figure 15 B; The multidigit of ACD piece #1 status information, ACD piece #3 status information and ACD piece #4 status information is changed " 00 " to indicate: because ACD piece #1, ACD piece #3 and ACD piece #4 do not have the data that are recorded in wherein or do not have invalid data, so ACD piece #1, ACD piece #3 and ACD piece #4 can be used for writing down ACD.Indication ACD piece #2 is that defective multidigit " 01 " keeps as ACD piece #2 status information.Because ACD piece #5 has the defective when reproducing, so the multidigit of ACD piece #5 status information is changed " 01 ".When the ACD piece has the defective when reproducing, ACD piece ACD_ID have value " 00h " that indication ACD piece can be used for writing down or " FFh " and about the status information of ACD piece by to indicate defective multidigit " 01 " to represent.In this case, when the ACD_ID of ACD piece with about the status information of ACD piece when inconsistent, because status information is considered to have precedence over ACD_ID, so the ACD piece is unavailable because of defective.Yet, when status information is because of wrong can not being extracted when in playback mode information, have " 00h " or " FFh " available as the ACD piece of its ACD_ID.
In above-mentioned arrangement, can be inconsistent by the state that the ACD_ID of the ACD in the ACD piece in the ACA that is comprised on the dish representes with the state of representing by the corresponding ACD block state information among the DDS that is recorded on the dish.In this case, drive system is designed at first depend on the ACD block state information that is recorded among the DDS.Below will be described in detail this.
Corresponding ACD block state information from be recorded in DDS and the ACD_ID that is recorded in the ACD piece among the ACA know the status information of ACD piece.If this information of two types is inconsistent each other, then drive system at first depends on the ACD block state information that is recorded among the DDS.When data because of, for example, the defective that in DMA, takes place and can not be reproduced by the DDS in DMA the time, drive system confirms to be comprised in the validity of the information in the ACD piece based on being recorded in ACD_ID among the ACA.Inconsistent can the generation between these two types of information because of the defective that during writing down, takes place.For example, when effective ACD was recorded among the ACD piece A, the state of ACD piece A was registered as " 11 " in DDS.Thereafter, if write ACD piece A and defective takes place with in response to the request of upgrading ACD piece A the time when upgrading ACD, then drive system will be recorded as defective of indication about the status information of ACD piece A.Yet, upgrades ACD and do not write ACD piece A, and ACD piece A still has effective ACD because of the defective during writing down.As a result, effectively the ACD_ID of ACD remains among the ACD piece A in the ACA.In this case, for the faulty operation of anti-locking system, must be at first with reference to the ACD block state information.
Yet when the ACD block state information among the DDS was unreliable because of the error correction failure that when DDS reproduces, is taken place in data becomes, best and nonessential, the validity of corresponding ACD piece was determined based on the ACD_ID of the ACD in the ACD piece that is comprised in the ACA.
Figure 16 is the process flow diagram that weighs initial method according to another embodiment of the present invention.With reference to Figure 16, in operation steps 1610, the dish 100 that has been used is written in the drive system.Then; Be included in the information (that is, being recorded in the ACD that coils on 100) of the operation that the ignorant function actuator of function that system controller 10 identification dma informations and regulation in the drive system know for system controller 10 and system controller 10 system must carry out.Then, in operation steps 1620, system controller 10 receives heavy initialization command through main frame I/F20 from main frame 3.
In operation steps 1630, system controller 10 control write/read unit 2 are with DMA and the information in ACA of reading and recording in the Lead-In Area that is included in dish 100, and take out this information.As an example, the information that is recorded among the DMA can be the write-protect sign, but and the information among the ACA of being recorded in can be the information that is included in the public information of ACD about recordability or form voltinism.
