The recording device includes a processing unit for specifying the address of the unit area in the data area and a control unit for recording data in the unit area of the specified address. The processing unit judges whether data is recorded in the unit area of thefirst address and specifies the first address or the second address in the same data area according to the judgment result. When recording of data into the specified address has failed, the control unit records the data in the spare area.
Description
Technical field
The present invention relates to have the management information area and the recording medium that has write down the user data area of user data of the management information that has write down the management accounts state.The invention still further relates to technology to such recording medium recording data.
Background technology
As can be between multiple arrangement compatible information recording carrier, CD is arranged.CD for example is the high-quality Blue-ray dish that is used for video and develops of DVD, high-resolution of developing for music and being used for the widely used CD of data in recent years, developing for digital video and sharply begin to popularize.
In these CDs, because the difference of recording and playback method, roughly be divided into and reproduce private type, can write down type, rewrite 3 kinds of types etc.Can write down type CD be to use can't deleted data made, each position on CD can only record data.CD-R and DVD-R can write down the type CD one time.In rewriting the type CD, on medium, can write down data many times in the same manner.For example CD-RW and DVD-RAM rewrite the type CD.
In can writing down type CD, because can't rewrite data, so be necessary management accounts finish district and recording areas not.In CD-R, be unit management record start position and end of record (EOR) position with the melody, thereby can be the unit additional record with the melody.The unit of melody is information track (track).It should be noted that " information track " below mentioned is not " information track " of the ditch shape of expression CD.
To CD-R, with information track unit from the periphery of CD inwardly week, record data in order.Information track that a plurality of records finish is as dialogue (session) management that comprises the information track that a plurality of records finish.The zone of the management information of storage administration recording status is program management district (below be also referred to as " PMA ").To DVD-R, due to RZone (information track that is equivalent to CD) and Border (session that is equivalent to CD), recordng management area (below be called " RMA ".The PMA that is equivalent to CD).
In the data configuration that in the RMA of DVD-R, writes down, the definition record management data (below, " RMD " 0 be called.The information of the position of maximum 2302 RZone of storage representation (information track that is equivalent to CD) in field4, field5～12 of RMD.
In the past to the recording method that can write down a type CD in, can only write down 1 time identical zone, thus if, just become distress condition sometimes once to the failure of the record in this zone, become can not additional record state.Though can and resume operation by retry sometimes, contact distress condition, whole reliabilities of the data that might not hold the record.
In addition, also consider on dish the alternate area is set, when the record of user area is failed, record in the alternate area, management is method for recording information alternately.At this moment, the given area on the dish is set to the alternate area in advance, when a plurality of replacing taken place, the situation of alternate area deficiency takes place.
In can writing down type CD, when wanting to rewrite the information in the zone of record data, also can alternately enter the recording method of in the alternate area, writing down.But at this moment irrelevant with having or not of the defective of coiling, consume the alternate area, so the exhaustion of alternate area takes place easily.
Summary of the invention

Below, the logical construct of CD is described, the data configuration of the management information that writes down in the CD is described then.
The logical data structure CD 101 of the CD 101 of Fig. 2 (a) expression present embodiment is to write down type one time.CD 101 have read in the district 102, user data area 103 and read the district 104.For fear of at not shown shaven head during near the edge of user data area 103, deflect away from from user data area 103 from the laser of shaven head, be absorbed in uncontrollable state, be provided with and read in district 102 and read district 104.User data area 103 comprises a recording areas at least.User data in user data area 103.
Further describe and read in district 102.In reading in district 102, management information area 105 is set.Management information area 105 records are used to manage the management information more than 1 106 to the recording status of CD 101.Comprise positional information in the management information 106 about the recording areas of user data area 103.In addition, makeing mistakes when comprising management accounts causes, replaces the rotation information of the position of record.It should be noted that Fig. 2 (b) expression guarantees to be used to replace the CD 101 of the spare area 107 that writes down.Fig. 3 represents the data configuration example of the management information 106 of present embodiment.But management information 106 comprises the inlet numbering arrangement 11 of the recording areas of management information title 10 additional records, the inlet 12 of a plurality of recording areas information.In order to discern a regulation management information title 10 in a plurality of management information 106.For but the recording areas regulation inlet numbering of discerning the additional record data arranges 11.Each recording areas information entry 12 comprises the starting position 13 of recording areas.Each recording areas inlet comprises next record starting position 15 and recording areas finishes end position 16.
It should be noted that the data configuration of management information 106 shown in Figure 3 is examples, also can adopt other data configurations.Fig. 4 represents other examples of the data configuration of management information.In this example, the not inlet of the not recording areas more than the recording areas management information title 21 and 1 22 is being set on the CD 101.And, as the inlet of recording areas not 22, the regulation next record starting position 15 and the end end position 23 of recording areas not.In view of the above, can manage not recording areas.
The recording areas of present embodiment is equivalent to the information track of CD-R or the RZone of DVD-R.Fig. 5 and Fig. 6 represent the management information of the RZone of DVD-R.Inlet numbering arrangement 11 for example shown in Figure 3 is corresponding to byte 5 with byte 0 shown in Figure 5.But promptly but each field of inlet numbering arrangement 11 is represented numbering additional record district, final entry district label 1 additional record district label 2 from top to bottom in order.By these recording areas numbering, but can manage the information of recording areas.For example in DVD-R, the recording areas number is 2302 to the maximum, but additional record district number mostly is 3 most, numbers the content of each field of arrangement 11 by the reference inlet, but determines the additional record district.In addition, each recording areas inlet 12 shown in Figure 3 and byte 15 shown in Figure 5 to byte 2047, that byte 0 shown in Figure 6 arrives byte 2047 is corresponding, represents the start address of each recording areas and the final entry address that finishes.
Suitably with reference to Fig. 7 and Fig. 8, describe the management of the not recording areas of present embodiment in detail below.
The transformation that not recording areas on Fig. 7 (a)～(c) expression CD 101 and record finish and distinguish.In Fig. 7 (a), user data area 103 comprises recording areas #1.Recording areas # 1 is Unrecorded state.The state that Fig. 8 (a) expression and the recording areas of the corresponding regulation of recording areas of Fig. 7 (a) enter the mouth.Inlet in drawing numbering is arranged uppermost field record in 11 as " 1 " of final entry district numbering, but arranges the numbering " 0 " of the recording areas of other additional records that other local registration expressions of 11 do not have recording areas # 1 in the inlet numbering.At recording areas inlet # 1, set P1 in the starting position 13 of recording areas #1.The beginning of user data area 103 is represented in this position.And end of record (EOR) end position 14 is set " 0 ", represent not record.In addition, set P1, set P0-1 finishing end position 16 in the starting end position 15 of recording areas not.It should be noted that position P0 represents to read the start address in district 104.
One of principal character of present embodiment is newly to be provided with field 15 and 16, records and narrates not the starting end position and the end end position of recording areas respectively.Below specify.At recording areas inlet # 1 and recording areas inlet # 3, the starting position of recording areas # 2 and recording areas # 3, end of record (EOR) end position 14, the not starting end position 15 and not end end position 16 settings " 0 " of recording areas of recording areas.It represents that each recording areas does not exist.
State behind Fig. 7 (b) expression reservation recording district # 1 and the recording areas #2.By receiving RESERVE TRACK order, carry out this reservation from higher level's control device 201.The such order from higher level's control device 201 of RESERVE TRACK order is defined by general Host Command specification.For example with reference to SFF 8090i specification " Mt.Fuji Command for Multimedia Devices " 4.16 the joint Recording for DVD-R media.
In Fig. 7 (b), change management information 106, thus be divided into recording areas # 1, recording areas # 2 from position P2 to position P3 from position P1 to position P2.Position P2 adds position P1 by the value of the size of RESERVE TRACK order appointment, does not also carry out record in any recording areas.
The state that Fig. 8 (b) expression and the recording areas of the corresponding regulation of recording areas of Fig. 7 (b) enter the mouth.Inlet numbering in drawing is arranged " 3 " that the uppermost field registration in 11 is numbered as the final entry district, in remaining field, but as additional record district numbering, registration " 2 " and " 1 ".The position relation of the order of the recording areas numbering of registering in the remaining field, corresponding recording areas is not related especially.And registration " 2 " in a side field, registration " 1 " in other fields.It should be noted that, but when not having the additional record district, registration " 0 ".In the starting position 13 of P2 setting recording district, position # 2, in the starting position 13 of P3 setting recording district, position #3.In addition, desired location P2, position P3 respectively in the starting end position 15 of the not recording areas of recording areas # 2 and recording areas # 3 are at the end end position 16 of the not recording areas of recording areas # 1, recording areas # 2, recording areas # 3 desired location P2-1, position P3-1, position P0-1 respectively.
State when Fig. 7 (c) is illustrated in user data among recording areas # 1 and the recording areas #2.At this moment, the end of record (EOR) position of recording areas # 1 is P4, and the end of record (EOR) position of recording areas # 2 is P5.The state that Fig. 8 (c) expression and the recording areas of the corresponding regulation of each recording areas of Fig. 7 (c) enter the mouth.End of record (EOR) end position 14 as recording areas # 1, desired location P4-1, to the starting end set positions position P4 of the not recording areas of recording areas # 1, to the end of record (EOR) end position 14 desired location P5-1 of recording areas # 2, to the starting end set positions position P5 of the not recording areas of recording areas # 2.
Fig. 9 (a)～(c) is illustrated respectively in the example of guaranteeing the alternate area under the recording status of Fig. 7 (c).Here, suppose the record failure that begins from the additional record position P4 of recording areas # 1, alternately record necessitates.
Fig. 9 (a) expression is used the recording areas # 3 that writes down as the alternate area example.The state of the record entry that Figure 10 (a) expression is corresponding with Fig. 9 (a).When alternately writing down in the present embodiment, field 19 and 20 are set newly, record and narrate the alternative source address respectively and replace destination address.Below, specify.
If as using the alternate area, then as the starting end position 15 of the not recording areas of recording areas # 3, desired location P6.As 18 (Fig. 3) that alternately enter the mouth, 19 set P4 in the alternative source address, are replacing setting recipient P3.In addition, the starting end set positions position P9 of the not recording areas in recording areas #1.When this setting means from the record failure that position P4 begins, also be considered as having write down.It should be noted that, the data volume from position P4 to position P9 with from the P3 of recording areas # 3 to P6 the data volume that writes down equate, be the zone length of the unit area (for example 1 sector or given continuous sector) of record failure.
Fig. 9 (b) but expression is used the end end of the recording areas that is in recording status as the alternate area a example.The state of the recording areas inlet that Figure 10 (b) expression is corresponding with Fig. 9 (b).As the end end position 16 of the not recording areas of recording areas # 1, desired location P7-1.At this moment, the rear end in zone that can user data among the recording areas # 1 becomes position P2-1～to position P7-1, recordable data volume minimizing among the recording areas #1.At this moment, as alternately entering the mouth 18,19 set P4 in the alternative source address, are replacing destination address 20 setting P7.It should be noted that,,, obtain position P7 from the end end position P2-1 inverse operation of recording areas # 1 according to the data volume of the data that should write down.As a result, the data volume from position P7 to position P2-1 equates with the data volume of the data that should write down.
Fig. 9 (c) expression is used the recording areas # 2 that writes down before in the way as the alternate area example.The state of the recording areas inlet that Figure 10 (c) expression is corresponding with Fig. 9 (c).As the starting end position 15 of the not recording areas in the recording areas # 2, desired location P8.In addition, as alternately entering the mouth 18,19 set P4 in the alternative source address, are replacing destination address 20 setting P5.
As management information, keep the starting end position and the information of the end end position of recording areas not of the not recording areas of each recording areas of expression, replace the target area thereby can in each recording areas, be provided with, use.
It should be noted that the information that keeps as management information is not limited to comprise the starting end position 15 of the not recording areas of representing each recording areas and the information both sides of the end end position 16 of recording areas not.When only the end end of the not recording areas of recording areas being used as the alternate area,, just can realize same purpose by an information of the end end position 16 of the not recording areas of each recording areas of maintenance expression.
In addition, when only the beginning end of the not recording areas of recording areas being used as the alternate area,, just can realize same purpose by an information of the starting end position 15 of the not recording areas of each recording areas of maintenance expression.
In addition, as shown in Figure 4, in management information 106, assemble and manage the not information of recording areas, comprise not recording areas management information title 21 and not recording areas inlet 22, also can realize same purpose.At this moment, each not recording areas inlet 22 comprise the starting end position 15 of recording areas not and the end end position 23 of recording areas not.
In addition,, the record requirement that begins for the additional record position in recording areas # 1 is described, record failure, the example of execution alternate treatment with reference to Fig. 9.Suppose record that generation begins from the additional record position position beyond requiring for example the record of recording areas # 1 finish the record of the position in district P1～P4 when requiring, generate alternately inlet, carry out record to the alternate area, also can realize same purpose.
Below with reference to Figure 11 and Figure 12, the recording processing of present embodiment is described.
Figure 11 represents the process of commands step of pen recorder 210.At first, in step 901, CD 101 is loaded in the pen recorder 210, if execution start up process, read the position of handling part 221 with regard to searching, managing information, up-to-date management information 106 is stored in the management information buffer 225, and the location storage of up-to-date management information 106 is arrived position diode-capacitor storage 224.
In step 902, I/F control part 211 receives the order that higher level's control device 201 sends, and access control portion 213 carries out the processing corresponding with command context.Fill order is handled, and up to discharge CD 101, or the power supply of pen recorder 210 disconnects.As the order that receives, suppose RESERVE TRACK order, CLOSE order and WRITE order.
In step 903, receive RESERVE TRACK when order from higher level's control device 201, processing is appended in management information processing portion 220 executive logging districts.
In step 904, receive CLOSE when order from higher level's control device 201, management information processing portion 220 executive logging districts close processing.Close processing by execution, this recording areas becomes the record that can't carry out from the additional record position.
In step 905, receive WRITE when order from higher level's control device 201, access control portion 213 is on one side with reference to the information of management information buffer 225, carry out recording processing to recording areas on one side.
In step 906, according to the execution result of the order of receiving from higher level's control device 201, renewal portion 222 is new administration information 106 more.
Below represent execution example from step 903 to step 906.
Under the state of the Fig. 7 that has loaded Unrecorded CD 101 (a), shown in Fig. 7 (b), receive the RESERVE TRACK order that is used to guarantee recording areas # 1, the RESERVE TRACK order that is used to guarantee recording areas # 2 from position P2 to position P3 from position P1 to position P2.At this moment, renewal portion 222 upgrades the starting position 13 of each recording areas and not the starting end position 15 of recording areas and the end end position 16 of recording areas, thereby finally management information 106 is stored in the management information buffer 225 shown in Fig. 8 (b).
Under the state of Fig. 7 (b), shown in Fig. 7 (c), receive to be used for ordering, being used in of the WRITE order of recording areas # 2 record from P2 position, position P5 at the WRITE of recording areas # 1 record from position P1～position P4.At this moment, data recording is carried out in given area on 213 pairs of CDs 101 of access control portion, and renewal portion 222 is as Fig. 8 (c) shown in, and the renewal end of record (EOR) end position 14 and the starting end position 15 of recording areas not are stored in the management information buffer 225.
Figure 12 represents the step of the recording processing of present embodiment.In step 1001, access control portion 213 receives the record requirement of logic-based address appointment from higher level's control device 201.
In step 1002, the described logical address of access control portion 213 appointments is transformed to physical address.Logical address is meant on the user data area 103 of CD 101, the address space that higher level's control device 201 is held.Usually, the starting position of user data area is handled as logical address 0.And physical address is represented the absolute position on the CD 101.If general, just become the value of physical address the value of logical address and certain off-set value addition.For example in DVD0-R, off-set value is 30000h.
In step 1003, access control portion 213 judges whether the physical address of conversion is the address of writing down the zone that finishes.The physical address of promptly judging conversion is included in that recording areas information 12.Particularly, judge that physical address is between which recording areas starting position 13 and record start position 15.Recording areas is not by recording areas starting position 13 and record start position 15 management.Therefore, when physical address did not exist in recording areas, access control portion 213 judged that the physical address of conversion is the interior address, zone that record finishes.
In step 1004, when being judged as record when not finishing in step 1003, renewal portion 222 is set at recording physical address to the physical address of conversion in the step 1002.
In step 1005, when being judged as record when finishing in step 1003, as the alternately destination address of the physical address after the conversion, renewal portion 222 sets the address of the next record starting position 15 in the recording areas information 12 arbitrarily.Perhaps, as replacing destination address, set the address in the alternate area 107.How selecting alternate physical address is arbitrarily.
In step 1005, when next record starting position 15 was set at alternately destination address, in step 1006, renewal portion 222 was updated to position after record is carried out to the next record starting positions 15 in the recording areas information 12.
In step 1007, the record that access control portion 213 carries out the physical address of setting.
In step 1008, access control portion 213 obtains the result of the recording processing of carrying out in the step 1007, if write down successfully, just transfers to step 1009, if step 1005 is just transferred in the record failure.
In step 1009, carry out when replacing the recording processing of target, upgrade the alternation administration information in the management information area 105.And, irrelevant with having or not of alternate treatment, about the recording areas of executive logging, upgrade the next record starting position 15 in the recording areas.Shown in Fig. 9 (a) alternately write down successfully the time, renewal portion 222 is updated to the state shown in Figure 10 (a) to management information 106, stores management information buffer 225 into.
It should be noted that, shown in Fig. 9 (b), as target physical address alternately, end end that can service recorder district #1.During to the record success of target alternately, in step 1009, renewal portion 222 is updated to the state shown in Figure 10 (b) to management information 106, stores in the management information buffer 225.

(embodiment 2)
In the present embodiment, on one side with reference to Figure 13, other examples of the recording processing (Figure 12) of explanation among the embodiment 1 just now are described on one side.In the present embodiment, utilize pen recorder 210 explanations of embodiment 1 to handle.
Figure 13 represents the step of the recording processing of present embodiment.This recording processing is corresponding with the step 905 of command process step shown in Figure 11.
With the relation of each step of Figure 12 in, the step 1801 of Figure 13, step 1802 and step 1803 difference.Particularly, replace step 1005 and the step 1006 of Figure 12, step 1801 and 1802 are set.In addition, in the step 1008 of Figure 12, the branch target of the processing during the record failure is a step 1005, but in Figure 13, changes to step 1803.
Below, the processing different with Figure 12 in the processing of Figure 13 mainly is described.Other steps are identical with Figure 12, so omit explanation.
In step 1801, but renewal portion 222 sets the additional record position of recording areas arbitrarily.For record alternately to the data of the physical address record of conversion in the step 1002, but set the additional record position.The reason that replaces record is that the physical address of conversion in step 1002 has recorded user data, can't carry out further record.In step 1802, but renewal portion 222 is the additional record position renewal of setting the position of writing down after carrying out.
When writing down failure in step 1008, step 1803 carries out.In step 1803, but renewal portion 222 is the additional record set positions in the alternate area to be used for the alternately zone of record.Alternately the reason of record is that the record that carries out in step 1008 is owing to misregistration is failed.And, the physical address of original physical address and record object is registered as alternately inlet.Handle then and get back to step 1007.
Here, Yi Bian with reference to Figure 14～Figure 16, the transformation based on the recording status on the CD 101 of above-mentioned recording method is described.
At first, the CD of present embodiment has the data configuration shown in Fig. 2 (b).Promptly in this CD, read the district before guarantee to be used to replace the spare area of record.Other structures are identical with Fig. 2 (a).
The logical data structure of the CD of Figure 14 (a)～(c) expression present embodiment.Read the district before guarantee the spare area.Other of this structure are identical with the relation of Fig. 7 (a)～(c).
Suppose now, in recording areas # 1 and recording areas # 2, shown in Figure 14 (c), write down user data like that.Under this recording status, pen recorder 210 receives from the record requirement of the 1 record unit that position P begins from higher level's control device 201, before the recording processing with this requirement finishes, receives the record requirement to position P6, position P7.
At first, it is 15 to be set at the position of P6 that the renewal portion 222 of pen recorder 210 begins the next record of recording areas # 1, from position P4 opening entry data.The failure of short of record, access control portion 213 is just at each position (address) of appointment record data.When the record failure, pen recorder 210 is carried out following processing.Here, from the record failure of the data of initial position P.
Figure 15 (a)～(c) expression uses different algorithms to replace the user data area of record.Figure 15 (a) is illustrated in the alternately example of record that position P4 is carried out in the additional record position of setting among the recording areas #1.In this example, pen recorder 210 carries out the alternately record of position P4 at position P6.For record requirement, can't carry out record to position P6 to position P6.Therefore, pen recorder 210 writes down the data that require for the record to position P6 at other positions P7.Can't carry out the record that requires for record so with that to position P6.Therefore, pen recorder 210 writes down the data that require for the record to position P7 at other positions P8.
As a result, renewal portion 222 generates the alternately inlet shown in Figure 16 (a).I.e. renewal portion 222 generate alternative source addresses 19 be position P4 and alternately destination address 20 for the inlet of position P6, alternative source address 19 for position P6 and alternately destination address 20 be position P7 for the inlet of position P7, alternative source address 19 and replace destination address 20 and be the inlet of position P8.If according to the alternately record shown in Figure 15 (a), it is complicated then alternately to enter the mouth, data volume also increases.
Shown in Figure 15 (a), if the record requirement is sent in the additional record position, then in recording processing each time, but be necessary to confirm the additional record position, write down next data.Such processing significantly makes execution speed descend.In view of the chance increase of large-capacity data such as recorded image-data is got up, but confirm that the algorithm of additional record position is impracticable during each recording processing.
And Figure 15 (b) is illustrated in the alternately example of record that the position P0 of alternate area 107 carries out position P4.In recording areas # 1, do not carry out the alternately record of position P4, so require and, can carry out in the position of carrying out to the record requirement of position P7 about record to position P6.As a result, renewal portion 222 generates the alternately inlet shown in Figure 16 (b).222 in i.e. renewal portion generates alternative source address 19 be position P4 and replaces destination address 20 and be the inlet of position P0.The quantity of colloid inlet is one, if compare with the example of Figure 16 (a), its complexity and quantity descend significantly.
It should be noted that, shown in Figure 15 (c),, can carry out the alternately record of position P10 from the additional record position of recording areas # 1 when existing when for example the record of position P requires in the zone that record finishes.Reason is position that 201 pairs of records of higher level's control device finish when sending record and requiring, and can control, thereby if recording processing finishes, just can carry out the additional record that begins from the additional record position.Promptly for the record requirement to position P10, access control portion 213 carries out alternately record to position P10 from position P4～P6-1.As a result, shown in Figure 16 (c), renewal portion 222 can only generate alternative source address 19 for position P10 and alternately destination address 20 be the inlet of position P4.In this moment, but the additional record set positions is P6.
Then, higher level's control device 201 is according to Read Track Information order, but the additional record position of affirmation recording areas # 1 is P6.This means position P4 is not carried out record then.Therefore, higher level's control device 201 does not require the execution of record then from position P4, from position P6 and position P7 requirement.According to this requirement, do not replace record, so renewal portion 222 need not newly-generated alternately inlet.Therefore, the inlet number is constant from the state shown in Figure 16 (c).
(embodiment 3)
In the present embodiment, on one side with reference to Figure 17, other examples of the recording processing (Figure 13) of embodiment just now are described on one side.In the present embodiment, utilize pen recorder 210 explanations of embodiment 1 to handle.
Figure 17 represents the step of the recording processing of present embodiment.This recording processing is corresponding with the step 905 of command process step shown in Figure 11.
With the relation of each step of Figure 13 in, the step 1901 of Figure 17, step 1902 are with difference.Particularly, replace the step 1803 of Figure 13, step 1901 and 1902 are set in Figure 17.
Below, the processing different with Figure 13 in the processing of Figure 17 mainly is described.Other steps are identical with Figure 13, so omit explanation.
Carry out when at first, step 1901 writes down failure in step 1008.Because the record failure, so pen recorder 210 is necessary to determine to replace the zone of record.Therefore, in the present embodiment,, change and handle according to from the having or not of the inquiry of higher level's control device 201.
In step 1901, I/F control part 211 utilizes Read TrackInformation order from higher level's control device 201, and whether affirmation exists the inquiry about the next record starting position of each recording areas of present management.When inquiry, shift to step 1902, when not inquiring about, shift to step 1801.
In step 1902, renewal portion 222 registers to original physical address and recording physical address alternately in the inlet.
And but the step 1801 when not inquiring about means set the additional record position in user data area.Do not utilize the alternate area, utilize user data area, carry out alternate treatment, can produce following advantage.Move to the alternate area with the shaven head that CD is carried out data recording and compare, displacement is short when user data area moves, and traveling time is also short.The time before alternate treatment finishes that this means shortens.Equally, also shorten the readout time of the data during reproduction processes.
In order to enjoy above-mentioned advantage, when higher level's control device 201 does not send the possibility of following record order, promptly not from higher level's control device 201 about the inquiry of record start position the time, be necessary to carry out the processing of step 1801.
And after the inquiry about the next record starting position of present management, if in user data, carry out alternate treatment, just can't be from the next record starting position record data of response.The next record starting position and the actual next record starting position of 201 management of higher level's control device do not match, and alternately the processing such as registration of inlet necessitate in addition.
Therefore, pen recorder 210 utilized user data area to carry out alternate treatment before the inquiry that has from higher level's control device 201.And, after inquiry is arranged, in user data area, do not carry out alternate treatment, utilize the alternate area to carry out alternate treatment.Be operated on the raising processing speed very effective like this.
Below with reference to Figure 14 (c), specify the alternate treatment of present embodiment.201 pairs of pen recorders 210 of higher level's control device send the requirement with 1 record unit (sector) record data from position P4.Then, record failure in the pen recorder 210.At this moment, pen recorder 210 is set at the next record starting position 15 of recording areas # 1 the position of P6.
Receive the record failure from position P4, I/F control part 211 is ordered by Read Track Information from higher level's control device 201, but judges whether the inquiry of the additional record position of present management.
When inquiry was arranged, renewal portion 222 was the alternately setting recipient of the position P4 of record failure the position P0 of alternate area 107.And when not inquiring about, renewal portion 222 is the alternately setting recipient of position P4 in the user data area, more specifically, and the position P in the identical recording areas #1.But renewal portion 222 is the additional record set positions of recording areas # 1 position P7, to position P6 record data.
According to the recording method of present embodiment, eliminating replaces record to the record position that higher level's control device 201 might then send record order, can prevent the alternately increase of inlet.
