In addition, can be the quantity of clearly indicating such as " n (piece) " that kind for example by the region quantity of virtual dividing in the storage part 340 by the user, also can be the quantity of setting according to the desirable kinescope image quality of user.

Storage part 340 after Fig. 2 (b) expression initialization process.Shown in Fig. 2 (b), storage part 340 is divided into the desirable n of user zone (zone 1～regional n) virtually.In addition, except the 1～n of zone, also be provided with in the storage part 340 and be used for writing down management area the zone 1～management information that regional n manages.

Shown in Fig. 2 (b), the management area can be divided into my disk management zone and the storage administration zone that my disk management zone is managed that zone 1～regional n is managed.

Record the management information that each zone of 1～regional n, zone is managed in my the disk management zone.Among Fig. 2 (b), for simplicity, the zone that records zone 1 management information of managing is called " clauses and subclauses 1 ", below likewise will record the management information that zone 2～n is managed the zone be called clauses and subclauses 2～n.

In the clauses and subclauses 1 that zone 1 is managed, record entry number, distribute labels, medium id information, range of distribution information, media key information and map information.Below, these various information are described.

" entry number " is that expression is carried out information of managing to which zone.For example, clauses and subclauses 1 are the management information that zone 1 is managed, and therefore record the information that entry number is shown " 1 ".

" distribute labels " is to represent whether be and my mark in the corresponding zone of dish.Under the state after initialization process just finishes, since not corresponding with my dish, therefore record the information (being " 0 " here) that expression distributes.

" medium ID " is the information of the medium ID of expression CD.In stage, there is not the information of recording medium ID in initialization process.About the information record of medium ID, will in the civilian described CD registration process in back, describe.

" range of distribution information " is the information that can be used as each regional posting field in the expression storage part 340.As the object lesson of range of distribution information, can enumerate out each regional start address and end address.In addition, also can write down each regional recording capacity to replace the end address.

" media key information " is the key information in the encryption usefulness that data recording is used to protect literary property to CD the time.As media key information, for example can enumerate out MKB (key media key block).

" map information " be expression about being recorded in each content on the CD, the address in the zone of this content of record is a virtual address and the address of representing to record on the storage part 340 zone of this content is the information of the corresponding relation between the physical address on the expression CD.Details about the mapping table that writes down as map information will be set forth at back stationery body, therefore omit its explanation here.

In addition, shown in Fig. 2 (b), storage administration records " entry number information " and " range of distribution information " in the zone." entry number " is by the information of the number of regions of virtual dividing in the expression storage part 340." range of distribution information " is the information in the zone in the expression disk management zone that is used as me in the storage part 340.

The remaining area that produces when in addition, storage part 340 being divided into zone 1～regional n virtually also can be applied flexibly to preparing the zone.

< CD registration process >

Next, with reference to (a) of Fig. 3 and (b) explanation CD registration process that storage part 340 is carried out.(a) of Fig. 3 and (b) be the figure of expression CD registration process, Fig. 3 (a) is the figure of an example of the demonstration of expression display device when the CD registration process, Fig. 3 (b) is the figure that schematically shows the storage part 340 after the CD registration process.

So-called CD registration process is meant the processing of the medium ID of recording disk on the clauses and subclauses of each zone of in to storage part 340, being cut apart managing virtually.

When CD was loaded into drive division 300, drive control part 320 display disc drive divisions 330 read the medium ID of this CD from the CD of being packed into.If dish drive division 330 reads medium ID from CD, drive control part 320 judges that whether the medium ID that reads in the storage parts 340 is the medium ID that has been recorded in my clauses and subclauses in disk management zone.

If the medium ID that reads is not recorded in my any one clauses and subclauses in disk management zone, drive control part 320 just with the medium ID that reads record in my clauses and subclauses in disk management zone, distribute labels is to represent not carry out on the clauses and subclauses of " 0 " that CD distributes.Thus, recording medium id information in clauses and subclauses.In addition, the distribute labels that has write down in the clauses and subclauses of medium id informations becomes " 1 " in the moment of recording medium id information, and expression distributes.And the intrinsic information of CDs such as media key information is also constantly recorded on the clauses and subclauses that write down the medium id informations at this.

Above-mentioned CD registration process has explained that the medium ID that is read is automatically recorded distribute labels and is the situation on the clauses and subclauses of " 0 ", but in fact, recorder device 100 inquires preferably whether the user records these medium ID on the clauses and subclauses.In this case, drive control part 320 receives the user will record the indication on the clauses and subclauses with medium ID to what recorder device 100 sent, comes recording medium ID.

In addition, when distribute labels was a plurality of for the clauses and subclauses of " 0 " exist, the user can select which clauses and subclauses medium ID is recorded on.In this case, drive control part 320 records medium ID on the specified clauses and subclauses of user.

In addition, when recording medium ID on the clauses and subclauses, be preferably in the image that shows on the display device shown in Fig. 3 (a).

The state of the storage part 340 under the situation of the video disc recording that Fig. 3 (b) expression will have a medium ID " aaa " on the clauses and subclauses 1 after the CD registration.

Record under the situation on the clauses and subclauses 1 at the medium ID with CD, shown in Fig. 3 (b), CD is corresponding with the zone 1 that clauses and subclauses 1 are managed.

In this instructions etc., will be called " my dish " with the CD that each regional corresponding CD in the storage part 340, medium ID itself that promptly had are recorded in the storage part 340.In addition, for the dish to me is discerned, will be called " dish 1 " with zone 1 corresponding my dish here.Below likewise, will be called " dish 2～n " with zone corresponding my dish of 2～n.

< contents booking video recording action >

Below, the video recording of the content in the recorder device 100 of having accomplished above-mentioned prior setting action, content playback action, Edition Contains action and content replication action are described.

With reference to (a)～(c) of (a)～(c)～Figure 13 of Fig. 4, action is explained as follows to the video recording of the content in the recorder device 100.Here, action describes to the content video recording to be treated to example with subscription and video recording.

Subscription and video recording in the recorder device 100 is handled can roughly be divided into preregistration processing and these two kinds of processing of video record processing.In addition, video record processing can be divided into these the two kinds of video record processing of video record processing under video record processing under my state of dish of having packed into and my state of dish of not packing into again.Below, these processing in the subscription and video recording processing are described respectively.

(preregistration processing)

At first, with reference to (a)～(c) of Fig. 4, the processing of the preregistration in the recorder device 100 is explained as follows.(a)～(c) of Fig. 4 is the figure that the preregistration in the expression recorder device 100 is handled; Fig. 4 (a) is the figure that schematically shows the state of the storage part 280 after preregistration is handled; Fig. 4 (b) is the figure of the state of storage part 340 and my dish 1 after schematically showing preregistration and handling, and Fig. 4 (c) is the figure of an example when preregistration is handled, showing of expression display device.

So-called preregistration is handled, and is meant the processing of registration subscription information on storage part 280 and CD.Handling for preregistration, is that example describes with the situation of having packed into the zone 1 corresponding dish 1 of storage part 340.

When the user imported subscription information via operation inputting part, rear end control part 240 recorded the subscription information of being imported in the reservation information management zone of storage part 280.At this moment, be recorded in subscription information in the reservation information management zone of storage part 280 shown in Fig. 4 (a), comprise the information of " video recording channel ", " video recording date ", " video time " and " becoming my dish of record object ".Below, be that example is explained the information of " my dish that becomes the record object " with my the medium ID of dish that is packed into, but also can be out of Memory, get final product so long as can discern the information of my dish.In addition, the various information that comprise in the subscription information can be that the user imports, and also can set according to the programme information of program user-selected in the expression electric program guide.

Rear end control part 240 records subscription information in the storage part 280, and indication drive control part 320 is written to subscription information on the dish 1 in the drive division 300 of packing into.The indication that drive control part 320 receives from rear end control part 240, the subscription information that display disc drive division 330 sets the user records on the dish 1.Dish drive division 330 receives the indication from drive control part 320, and the subscription information that the user is set records in the regulation zone (reservation information management zone) of dish 1 (Fig. 4 (b)).At this moment, because dish has write down medium ID on 1, therefore also recording medium ID no longer.

In addition, when setting subscription information, the user also can be selected to my dish of record object.In this case, when user-selected my dish that becomes the record object is not packed drive division 300 into, preferably give the alarm to the user, make it will be as my dish of the object drive division 300 of packing in the moment of registration subscription information.

Among Fig. 4 (c), be illustrated in when having carried out preregistration under the situation of having packed into the zone 1 corresponding dish 1 of storage part 340 example attending institute's images displayed in display device.

(video record processing under my situation of dish of having packed into)

Next, with reference to (a) of Fig. 5 and (b), the video record processing that has having packed in the drive division 300 under my situation of dish of following medium ID describes, and these medium ID is included in the subscription information that is write down in the reservation information management zone of storage part 280.(a) of Fig. 5 and (b) be the figure that is illustrated in the video record processing under my state of dish of having packed into; Fig. 5 (a) is the figure that schematically shows the state of storage part 340 and my dish 1 after the video record processing, and Fig. 5 (b) is the figure that schematically shows the state of the storage part 280 after the video record processing.

When the video recording of content 1 finishes, shown in Fig. 5 (b), rear end control part 240 will represent that the subscription information that content 1 is carried out subscription and video recording deletes from the reservation information management zone of storage part 280.In addition, when having accomplished content 1 is recorded 1 last time of dish, the subscription information of drive control part 320 display disc drive divisions 330 deletion records in dish 1 reservation information management zone.

Next, with reference to (a)～(c) of Fig. 6, explain content 1 is recorded the zone 1 of storage part 340 and the state of storage part that coiled for 1 last time 340 and storage part 280.(a)～(c) of Fig. 6 is the figure of the state of storage part 340 and the storage part 280 of expression when content 1 has been carried out video recording; Fig. 6 (a) be expression with the zone 1 of storage part 340 in the figure of corresponding relation of recording status of the corresponding dish 1 of recording status of content; Fig. 6 (b) is the figure of the mapping table of expression when content 1 has been carried out record, and Fig. 6 (c) is the figure of the title admin table of expression when content 1 has been carried out record.

Here, the zone 1 of storage part 340 is normally inequality with the data capacity of dish 1.Therefore, in zone 1, except physical address, also distributed and the consistent virtual address in address (first area appointed information) of coiling on 1.Through reading or write data with this virtual address, thus can be in rearward end 200 as handle on the dish 1 of content record in the drive division 300 of packing into that will leave in the storage part 340 suchly.In these instructionss etc., the represented storage area of setting in will each zone with storage part 340 of virtual address is called " virtual disk reflection ".

Virtual disk reflection among Fig. 6 (a) in the zone 1 of expression storage part 340.Shown in Fig. 6 (a); In the zone 1 of storage part 340, serve as beginning address recorded content 1 (data capacity: in the time of XGB), on the virtual disk reflection, serve as to start address recorded content 1 with virtual address " 0x050 " with physical address (second area appointed information) " 0x000 ".That is to say, content 1 is being written under dish 1 the situation that drive control part 320 display disc drive divisions 330 begin to write content 1 from the sector of coiling 1 address and being shown " 0x050 ".Thus, can be easily from zone 1 with content record to dish 1.

Then, with reference to Fig. 6 (b), the mapping table that the physical address shown in Fig. 6 (a) and virtual address associate is described being used for.

Mapping table is as the map information in my the disk management zone of storage part 340 and carry out record.Shown in Fig. 6 (b), in the mapping table,, the memory mapped of the mapping in the zone 1 of the virtual disk mapping of the mapping in the expression virtual disk reflection and expression storage part 340 associated carry out record for each content.Also whether content and this content of expression being recorded in sync mark on my dish associates and carries out record.

In addition, in this instructions etc., with the content in the some zones that are recorded in storage part 340 be recorded in corresponding my dish in this zone on state be called " synchronously ".Equally, with the content record in the some zones that are recorded in storage part 340 to corresponding my dish in this some zone on processing be called as " synchronous processing ".

Content in the mapping table is updated when content 1 is recorded in the zone 1.The mapping table of zone 1 under the state shown in Fig. 6 (a) of storage part 340 has been shown among Fig. 6 (b).Shown in Fig. 6 (b), in the mapping table, the beginning address of content 1 in the virtual disk mapping is set as " 0x050 ", and size of data is set as XGB, and the beginning address in the memory mapped is set as " 0x000 ", and size of data is set as XGB.In addition, from zone 1 to dish 1 write end in, the sync mark in the mapping table becomes " 1 ", the expression content has been recorded on my dish.

Through with reference to this mapping table, thereby control part 240 receives that the drive control part that writes instruction 320 that writes to dish 1 can become the instruction that writes that writes to dish 1 that the control part 240 from the rear end is received to what zone 1 write and write instruction from the rear end.In addition, for also identical, through with reference to mapping table, thereby can it be become the reading command that reads from zone 1 from the situation of coiling 1 reading command that reads.

In addition, the entry parameter among Fig. 6 (b) is the zone of entries number, medium id information, range of distribution information etc., the entry data zone be the recording medium key information with zone 1 in the zone of magnetic track information etc.

In addition, when content 1 was recorded in the zone 1, the title admin table as the title management information record in the title management area of the dish 1 in storage part 280 also was updated.With reference to Fig. 6 (c), the title admin table that writes down in the Content Management zone that is provided with the information relevant with content 1 is described.In addition, the title management area is arranged in the storage part 280, and the quantity of title management area is equivalent to the region quantity cut apart in the storage part 340 virtually.

In the title admin table, shown in Fig. 6 (c), the associating information that the title name and the residue of expression playback of content required time, playback of content image quality, content of each content of expression are transcribed number of times (being to the maximum 10 times) and synchronous regime gets up to carry out record.In addition, the title with expression content 1 is designated as title 1.Equally, the title with expression content 2～content n is designated as title 2～title n.

Shown in Fig. 6 (c) is an example of the title admin table when the mapping table of having set shown in Fig. 6 (b).At this moment, because content 1 has been recorded on the dish 1, so the residue of title 1 is transcribed number of times, and to become " 9 " after deducting 1 time 10 times inferior from remaining.

(video record processing under my situation of dish of not packing into)

Next, with reference to (a) of Fig. 7 and (b), the video record processing that has not packing in the drive division 300 under my situation of dish of following medium ID describes, and these medium ID is included in the subscription information that is write down in the reservation information management zone of storage part 280.(a) of Fig. 7 and (b) be the figure that is illustrated in the video record processing under my state of dish of not packing in the recorder device 100; Fig. 7 (a) is the figure that schematically shows the state of the storage part 340 after the video record processing, and Fig. 7 (b) is the figure that schematically shows the state of the storage part 280 after the video record processing.

In the recorder device 100; The moment that the content (content 2) that the subscription information that on the reservation information management zone according to storage part 280, is write down will be recorded a video begins to record a video; Under the situation of dish 1, rear end control part 240 does not indicate drive control part 320 that content 2 is recorded on the dish 1 yet even pack in the drive division 300.The dish 1 owing to do not pack in the dish drive division 330; Therefore receive from the drive control part 320 of the indication of rear end control part 240 and will become to what the zone 1 of storage part 340 write and write instruction, and content 2 is recorded in the zone 1 from the instruction that writes that writes to dish 1 of rearward end 200.At this moment, because packing into, dish 1 in the drive division 300, therefore do not carry out content 2 is recorded the processing on the dish 1.

When the video recording of content 2 finishes, shown in Fig. 7 (b), rear end control part 240 will represent that the subscription information that content 2 is carried out subscription and video recording deletes from the reservation information management zone of storage part 280.

Next, with reference to (a)～(c) of Fig. 8, the storage part 340 and the state of storage part 280 that content 2 are recorded the 1 last time of zone of storage part 340 are described.(a)～(c) of Fig. 8 is the figure of the state of storage part 340 and the storage part 280 of expression when content 2 has been carried out video recording; Fig. 8 (a) be expression with the zone 1 of storage part 340 in the figure of corresponding relation of recording status of the corresponding dish 1 of recording status of content; Fig. 8 (b) is the figure of the mapping table of expression when content 2 has been carried out record, and Fig. 8 (c) is the figure of the title admin table of expression when content 2 has been carried out record.

Shown in Fig. 8 (a); Owing to serve as beginning address recorded content 1 (data capacity: XGB), serve as to start the address to be connected on content 1 recorded content 2 (data capacities: XGB) afterwards therefore in the zone 1 of storage part 340 with the physical address " 0x200 " in the zone 1 of storage part 340 with physical address " 0x000 ".At this moment, on virtual disk reflection, also be serve as that the beginning address is connected on content 1 recorded content 2 afterwards with virtual address " 0x250 ".Because packing into, dish 1 in the drive division 300, therefore need not content 2 not recorded on the dish 1 certainly

When content 2 was recorded in the zone 1, the mapping table that map information write down in the clauses and subclauses 1 of storage part 340 also was updated.The mapping table of zone 1 under the state shown in Fig. 8 (a) of storage part 340 has been shown among Fig. 8 (b).Shown in Fig. 8 (b); On the basis of the mapping table shown in Fig. 6 (b); Also carried out following setting: the beginning address of content 2 in the virtual disk mapping is set as " 0x250 "; Size of data is set as XGB, and the beginning address in the memory mapped is set as " 0x200 ", and size of data is set as XGB.At this moment, owing to do not write to dish 1 from zone 1, so the sync mark of content 2 becomes " 0 " in the mapping table, the expression content is not recorded on my dish.

An example of the title admin table when in addition, Fig. 8 (c) is illustrated in the mapping table of having set shown in Fig. 8 (b).Shown in Fig. 8 (c), in the title admin table, except the title management information of the title 1 of the expression content 1 shown in Fig. 6 (c), also added the title management information of the title 2 of expression content 2.At this moment and since title 2 be recorded in the dish 1 on, so the residue of title 2 transcribe number of times still for " 10 " inferior, synchronous regime then is to represent not synchronous information.

(content synchronization processing)

Next, with reference to (a)～(c) of Fig. 9～Figure 11, explanation will be recorded in content in the storage part 340, promptly not be recorded in the synchronous processing of content record to my dish on my dish.

When coiling 1 when packing in the drive division 300, drive control part 320 judges that just with reference to the mapping table of clauses and subclauses 1 whether sync mark is arranged is the content of " 0 ".For example, when existing sync mark to be the content 2 of " 0 ", drive control part 320 display disc drive divisions 330 will be recorded in content 2 records (writing) in the zone 1 of storage part 340 to dish 1.The indication that dish drive division 330 receives from drive control part 320 is written to dish 1 with the content in the zone that is recorded in storage part 340 12.Thus, the content 1 that becomes in the zone 1 that is recorded in storage part 340 all has been recorded in the state (Fig. 9) that coils on 1 with content 2.That is, content 2 becomes synchronous regime.

When the processing that writes content 2 to dish 1 finished, drive control part 320 had finished this advisory rearward end 200 with the synchronous processing of content 2.Rear end control part 240 receives this notice, upgrades the title admin table in the title management area that is recorded in the dish 1 in the storage part 280.

In addition, when the processing that writes content 2 to dish 1 finishes, the subscription information that be used for content 2 carried out subscription and video recording of drive control part 320 display disc drive divisions 330 deletion records on dish 1.Receive the subscription information (Fig. 9) that be used for content 2 carried out subscription and video recording of dish drive division 330 deletion records in the reservation information management zone of dish 1 of indication.In addition, Fig. 9 is storage part 340 after the expression content synchronization is handled and the figure that coils 1 state.

Next, with reference to (a)～(c) of Figure 10, explanation will be recorded in the state that content 2 in the zone 1 of storage part 340 is written to dish 1 o'clock storage part 340 and storage part 280.(a)～(c) of Figure 10 is the figure of the state of storage part 340 and the storage part 280 of expression when content 2 carried out synchronous processing; Figure 10 (a) be expression with the zone 1 of storage part 340 in the figure of corresponding relation of recording status of the corresponding dish 1 of recording status of content; Figure 10 (b) is the figure of the mapping table of expression when content 2 carried out synchronous processing, and Figure 10 (c) is the figure of the title admin table of expression when content 2 has been carried out synchronous processing.

Shown in Figure 10 (a), on the virtual disk reflection, content 2 serves as that record is carried out in the beginning address with virtual address " 0x250 ".At this moment, owing on dish 1, can serve as beginning address recorded content 2 with " 0x250 ", therefore, content 2 serves as that the beginning address is recorded in and coils on 1 to coil 1 address " 0x250 ".

When the synchronous processing of content 2 finished, shown in Figure 10 (b), the sync mark that is recorded in the mapping table in the map information of clauses and subclauses 1 became " 1 ", and the expression content has been recorded on my dish.In addition, shown in Figure 10 (c), in the title admin table of the dish 1 that storage part 280 is write down, the residue of title 2 transcribes that to become " 9 " after number of times deducts 1 inferior, and synchronous regime also becomes the synchronous information of expression simultaneously.

Next, with reference to (a)～(d) of Figure 11, having write down in the explanation dish 1 with " 0x250 " is the synchronous processing of content 2 under the situation of content (content 3) of beginning address.

(a)～(d) of Figure 11 is the figure of the state of storage part 340 and the storage part 280 of expression when content 2 carried out synchronous processing; Figure 11 (a) has write down the figure of state that beginning address with the content 2 on the virtual disk reflection is the content 3 of beginning address in the indicating panel 1; Figure 11 (b) is that expression changes the virtual disk reflection so that content 2 is connected on the figure of content 3 state afterwards; Figure 11 (c) is the figure of the mapping table of expression when content 2 carried out synchronous processing, and Figure 11 (d) is the figure of the title admin table of expression when content 2 has been carried out synchronous processing

Shown in Figure 11 (a), write down in 1 under the situation of content 3 that beginning address " 0x250 " with the content 2 in the virtual disk reflection serve as the beginning address at dish, can't serve as to start address recorded content 2 just coiling on 1 to coil 1 address " 0x250 ".

At this moment, drive control part 320 coils on 1 thereby can content 2 be recorded through the virtual disk reflection in the change storage part 340.That is to say; Drive control part 320 carries out following setting: will in dish 1 serve as beginning address and content recorded 3 serve as to start the address to carry out record with virtual address " 0x250 " also in the virtual disk reflection with address " 0x250 "; And with content 2 with virtual address " 0x400 " serve as the beginning address carry out record, content 2 is connected on after the content 3.That is the virtual disk reflection in the drive control part 320 change zones 1.Thus, in after changing virtual disk reflection, the beginning address of content 2 becomes " 0x400 ", can serve as beginning address and content 2 is recorded on the dish 1 with " 0x400 " therefore.

At this moment, the mapping table in zone 1 also becomes shown in Figure 11 (c).That is, the beginning address of the content 2 in the virtual disk mapping becomes " 0x400 ", and sync mark becomes " 1 ", and the expression content record is on my dish.In addition, in the virtual disk mapping, having registered the beginning address is that " 0x250 " and data capacity are the content 3 of YGB.Because content 3 is the contents that are not recorded in the zone 1, so do not write down the beginning address in the memory mapped, do not write down sync mark yet.

Equally, shown in Figure 11 (d), in the title admin table of the dish 1 in storage part 280, become the synchronous information of expression, registered title 3 information corresponding (playback duration and playback image quality) with expression content 3 with title 2 corresponding synchronous regimes.At this moment, content 3 is the contents that only are recorded on the dish 1, can't transcribe, so the residue in the title 3 is transcribed also not demonstration of number of times.

(situation of deletion content when having packed my dish into)

Next, the situation of under my state of dish of having packed into, having deleted content is described.In addition,, will set forth, therefore omit its explanation here at back stationery body about the content deletion under my state of dish of not packing into.

When the idle capacity in the zone in the storage part 340 1 tails off, as long as the content of deletion record in zone 1.For the deletion that is recorded in the content of zone in 1, can be to carry out according to user's indication, also can arrive setting at the idle capacity in zone 1 and automatically perform when following.

Figure 12 is that the storage part 340 that is recorded in when content 4 has been descended in new again record after the content 1 of zone in 1 and the content 2 and the figure of the state of dish 1 have been deleted in expression.In addition, among Figure 12, owing to be the video recording that under my state of dish of having packed into, carries out, so content 4 has also been recorded on the dish 1.

Next, (a)～(c) with reference to Figure 13 explains state shown in Figure 12, the storage part 340 when promptly after the zone has been deleted content 1 and content 21, in zone 1, having write down content 4 again and the state of storage part 280.(a)～(c) of Figure 13 is the figure of the state of storage part 340 and the storage part 280 of expression when content 4 has been carried out video recording; Figure 13 (a) be expression with the zone 1 of storage part 340 in the figure of corresponding relation of recording status of the corresponding dish 1 of recording status of content; Figure 13 (b) is the figure of the mapping table of expression when content 4 has been carried out record, and Figure 13 (c) is the figure of the title admin table of expression when content 4 has been carried out record.

When will be from the zone when 1 deletion content 1 is with content 2, the relevant information of deletion and content 1 and content 2 memory mapped of the mapping table of drive control part 320 on the clauses and subclauses 1 that are recorded in storage part 340.In addition, drive control part 320 will also be deleted with the sync mark that content 1 and content 2 are associated.Like this, the deletion of the content under my state of dish of having packed into is deleted identical with the content in the hybrid recording apparatus.

But in this embodiment, shown in Figure 13 (a), content 1 does not disappear on the virtual disk reflection with content 2, still keeps.That is, shown in Figure 13 (b), even from regional 1 deletion content 1 and content 2, the information of content 1 and content 2 is not deleted from the virtual disk mapping of mapping table yet, still keeps.

Therefore, drive control part 320 display disc drive divisions 330 are connected in the virtual disk reflection recorded content 4 after the content recorded 2, serve as to start address recorded content 4 with virtual address " 0x650 " promptly.

In addition, shown in Figure 13 (c), along with content 1 and content 21 deletion from the zone, the title admin table in the storage part 280 is change thereupon also.When the content of wanting deletion record in zone 11 and content 2, the residue of expression content 1 and content 2 is transcribed the information of number of times and synchronous regime in the title admin table of rear end control part 240 deletion storage parts 280.Then, if with content 4 record the zone 1 in the time, rear end control part 240 will represent that the relevant information of the title (title 4) of content 4 registers in the title admin table.

In addition, in this example, situation about keeping with the content that will be recorded in the dish 1 is that example is illustrated, but also can the content that be recorded in the dish 1 also be deleted certainly.In this case, the content information in the virtual disk mapping that is recorded in the mapping table on content of coiling on 1 and the clauses and subclauses 1 that are recorded in storage part 340 is also deleted.In addition, with the heading message in the title management area that is recorded in storage part 280 also deletion in the lump.

< content playback action >

Next, with reference to Figure 14～Figure 17, action is explained as follows to the content playback in the recorder device 100.

It is the processing of receiving that the user carries out via the content playback indication back of operation inputting part input that content playback is handled.For example, if the user selects the title that shows on the display device is reset, rear end control part 240 is made as has received the playback indication that the content of selected title representative is reset, to the processing of resetting of this content.In addition, the title that is shown on the display device is exactly the title of identification in rearward end 200.In other words the title of identification is exactly the title of being registered on the title admin table that writes down in the title management area of storage part 280 in the rearward end 200.

In addition, the content playback in the recorder device 100 action can be divided into roughly that playback under my situation of dish of having packed into is handled and my situation of dish of not packing under playback handle.Below, various playbacks processing are described.

(playback under my situation of dish of having packed into is handled)

Below, with reference to Figure 14 and Figure 15, the playback under my situation of dish of having packed into handled describing.Figure 14 is the figure that is illustrated in the state of storage part 340 and storage part 280 under the situation of the dish 1 that records content 1～3 of having packed into.Figure 15 is the figure that is shown schematically in the medium that the playback time content is read under my situation of dish of having packed into.

Dish 1 shown in figure 14, as to have packed in the drive division 300 and recorded content 1～3 has write down content 1 and content 2 in the zone 1 of storage part 340.Therefore, in the title admin table of the title management area of storage part 280, write down the information relevant with title 1～3.That is, in rearward end 200, can discern the content 1～3 of title 1～3 representative.In addition, among Figure 14, omitted the details of title admin table.

Handle as the playback under my situation of dish of having packed into; At first; Explanation all has in 1 the playback under the situation that content recorded 1 resets to handle coiling 1 with the zone, and then, explain has record but playback processing under unwritten content 3 is reset in the zone 1 the situation to coiling on 1.

The instruction that rear end control part 240 reads content recorded 1 on the dish 1 via interface portion 290 to drive division 300 outputs.Receive drive control part 320 from the instruction of rear end control part 240 with reference to mapping table, whether content recorded 1 is recorded in the zone 1 on the judgement dish 1.At this moment, because content 1 is to be recorded in the content of zone in 1, so drive control part 320 is with reference to mapping table, will be from the rear end control part 240 is received is transformed to the reading command that reads from zone 1 from coiling 1 reading command that reads.That is, drive control part 320 is the physical address in zone 1 with reference to mapping table with the address mapping that coils 1.

The drive control part 320 that has read content 1 from zone 1 outputs to rearward end 200 with the content that is read 1 via interface portion 310.

Like this, shown in figure 15 when in my dish and storage part 340, all recording the content that becomes reading object, from storage part 340 reading of content.

Record is arranged on 1 but unwritten content 3 situation of resetting too in the zone 1 to coiling, the instruction that rear end control part 240 will read content recorded 3 on the dish 1 outputs to drive division 300 via interface portion 290.Receive drive control part 320 from the instruction of rear end control part 240 with reference to mapping table, whether content recorded 3 is recorded in the zone 1 on the judgement dish 1.At this moment because content 3 is not to be recorded in the content of zone in 1, so drive control part 320 according to the control part 240 from the rear end receive from coiling 1 reading command that reads, display disc drive division 330 reading of content 3.

From coil 1 read content 3 after, drive control part 320 outputs to rearward end 200 with the content that is read 3 via interface portion 310.

Like this, shown in figure 15 when in storage part 340, not having record to become the content of reading object, from my dish reading of content.

(playback under my situation of dish of not packing into is handled)

Below, with reference to Figure 16 and Figure 17, the playback under my situation of dish of not packing into handled describing.Figure 16 is do not pack in the drive division 300 figure of state of storage part 340 and storage part 280 under the situation of CD of expression.Figure 17 is the figure that is shown schematically in the medium that the playback time content is read under my situation of dish of not packing into.

Shown in figure 16, in the zone 1 of storage part 340, record content 1 and content 2.Yet what they were different with the situation of Figure 14 is the dish 1 of not packing in the drive division 300 and recording content 1～3.In addition, in the title admin table of the title management area of storage part 280, write down the information relevant with title 1～3.That is, in rearward end 200, can discern the content 1～3 of title 1～3 representative.In addition, identical among Figure 16 with Figure 14, omitted the details of title admin table.

Under the situation of state shown in Figure 16; The content 1 that is recorded in the content 1～3 of title 1～3 representative that can be discerned rearward end 200 in the zone 1 of storage part 340 is reset with content 2, for only on dish 1, having content recorded 3 then can not reset.

That is, shown in figure 17, when all recording the content that becomes reading object in dish and the storage part 340 at me, through carrying out and packed my the identical processing of situation of dish into, thereby from storage part 340 reading of content.But, for only on dish 1, having content recorded then can't be read.

In addition, the reading of content 1 shown in Figure 17 handle with reading of content 1 under my situation of dish of having packed into handle identical, therefore omission explanation here.

< Edition Contains action >

Next, with reference to Figure 18 and Figure 19 (a), Figure 19 (b), action is explained as follows to the Edition Contains in the recorder device 100.

It is the processing of receiving that the user carries out via the Edition Contains indication back of operation inputting part input that Edition Contains is handled.For example, if the user selects the title that shows on the display device is edited, rear end control part 240 is made as has received editor's indication that the content of selected title representative is edited, and user-selected content is carried out editing and processing.In addition, the title that is shown on the display device is exactly the title of identification in rearward end 200.In other words the title of identification is exactly the title of being registered on the title admin table that writes down in the title management area of storage part 280 in the rearward end 200.That is,, no matter be recorded on which medium, can both carry out editing and processing it for the title of registering on the title admin table.

The action of Edition Contains in the recorder device 100 also with content playback handle the same, can roughly be divided into the editing and processing under my situation of dish of having packed into and my situation of dish of not packing under editing and processing.Below, various editing and processing are described.

In addition; So-called Edition Contains is handled; Being meant on the dish that is recorded in me or the processing of changing of at least a portion data of the content in the storage part 340, specifically is the processing in being added on of chapters and sections in deletion and the content of the scene deletion (changing a part of content-data) that comprises content, content.Here, deleting with the scene of content is that example describes, and also can likewise handle for other processing.In addition, handle, as above-mentioned, be illustrated, and specifically set forth below, therefore omit its explanation here for my state of dish of not packing into for my state of dish of having packed into about the deletion of content.

(editing and processing under my situation of dish of having packed into)

Below, with reference to Figure 14 and Figure 18, the editing and processing under my situation of dish of having packed into is described.Figure 18 is the figure that is shown schematically in the medium that content is edited under my situation of dish of having packed into

Dish 1 shown in figure 14, as to have packed in the drive division 300 and recorded content 1～3 has write down content 1 and content 2 in the zone 1 of storage part 340.In addition, in the title admin table of the title management area of storage part 280, write down the information relevant, in rearward end 200, can discern the content 1～3 of title 1～3 representative with title 1～3.In addition, among Figure 14, omitted the details of title admin table

Handle as the playback under my situation of dish of having packed into; At first; Explanation all has the processing under the situation that content recorded 1 edits to coiling 1 in 1 with the zone, and then, explain has record but processing under unwritten content 3 is edited in regional 1 the situation to coiling on 1.

The instruction that rear end control part 240 changes the data of coiling content recorded 1 on 1 to drive division 300 outputs via interface portion 290.Receive drive control part 320 from the instruction of rear end control part 240 with reference to mapping table, whether content recorded 1 is recorded in the zone 1 on the judgement dish 1.At this moment, because content 1 is the content that is recorded in the zone 1, so drive control part 320 will be the instruction of the data the change zone 1 from the instruction map of the data on the change dish 1 that rear end control part 240 is received with reference to mapping table.That is, drive control part 320 is the physical address in zone 1 with reference to mapping table with the address mapping that coils 1, and therefore, the data that are actually being recorded in the content 1 in the zone 1 change.

Like this, shown in figure 18 when in my dish and storage part 340, all recording the content that becomes the data change object, the data that are recorded in the content in the storage part 340 are changed.

Yet, can make on the dish 1 content recorded 1 (asynchronous regime) still inequality in the content recorded 1 and zone 1 like this, therefore, drive control part 320 will also be reflected to the data change that content recorded 1 in the zone 1 is carried out on the dish 1 on the content recorded 1.Change is reflected on the dish 1 can carries out at any time on the content recorded 1, so long as before drive division 300 takes out, get final product at dish 1.

For dish record is arranged on 1 but the situation that the data of unwritten content 3 change in the zone 1 too, the instruction that rear end control part 240 will change the data of coiling content recorded 3 on 1 outputs to drive division 300 via interface portion 290.Receive drive control part 320 from the instruction of rear end control part 240 with reference to mapping table, whether content recorded 3 is recorded in the zone 1 on the judgement dish 1.At this moment, because content 3 is not to be recorded in the content of zone in 1, so the instruction of changing of the data to coiling content recorded 3 on 1 received according to the control part 240 from the rear end of drive control part 320, the data of 330 pairs of contents 3 of display disc drive division change.

(editing and processing under my situation of dish of not packing into)

Next, with reference to Figure 16 and Figure 19 (a), Figure 19 (b), the editing and processing of the content under my situation of dish of not packing into is described.(a) of Figure 19 and (b) be shown schematically under my situation of dish of not packing into, the figure of medium that content is edited; Figure 19 (a) expression dish of not packing into became the medium of edit object at 1 o'clock, and Figure 19 (b) expression has been packed into to coil and change place has been reflected to the situation on the dish 1 at 1 o'clock.

Under the situation of state shown in Figure 16, be recorded in can content 1～3 title 1～3 representative discerned in the rearward end 200 content 1 and content 2 in the zone 1 of storage part 340 carry out with 1 the situation of coiling of having packed under identical editing and processing.

That is, shown in Figure 19 (b), when in other recorder device to coiling 1 content 2 when having carried out change, the change that drive control part 320 will coil the content 2 in 1 is reflected on the content 2 that is recorded in the zone 1.At this moment, the mapping table that is recorded on the clauses and subclauses 1 also is updated in the lump.

< content replication action >

Next, with reference to (a) of Figure 20 and (b), the action of the content replication in the recorder device 100 is explained as follows.Here, be that example describes with replication actions in the storer in the storage part in the recorder device 100 340.In addition, replication actions in the so-called storer also can be referred to as to transcribe action in the storer in the recorder device 100.(a) of Figure 20 and (b) be the figure of replication processes in the storer of expression in the recorder device 100; Figure 20 (a) is the figure of the state of the storage part 340 after the replication processes in the expression storer, and Figure 20 (b) is the figure of the state of the title management area in the storage part 280 after the replication processes in the expression storer.

Replication processes is the processing of receiving that the user carries out via the content replication indication back of operation inputting part input in the storer of content.For example; When the user selects title from the title that display device shows; And decision with selected replication of titles to a certain when zone; Rear end control part 240 is used as the indication of having received the content replication of the selected title representative zone in the selected storage part 340, and this content is carried out replication processes in the storer.In addition, the title that is shown on the display device is exactly the title of identification in rearward end 200.In other words the title of identification is exactly the title of being registered on the title admin table that writes down in the title management area of storage part 280 in the rearward end 200.

Receive that the rear end control part 240 indication drive control parts 320 that copy to the indication on the zone 2 of storage part 340 from the content 2 in user's the zone that will be recorded in storage part 340 1 record content recorded 2 in the zone 1 on regional 2.Receive that drive control part 320 from the indication of rear end control part 240 shown in Figure 20 (a), records content 2 on the zone 2.At this moment, drive control part 320 upgrades and is recorded in the mapping table on the clauses and subclauses 2.In addition, identical for the record of content 2 in the zone 2 and the renewal of the mapping table that carries out thereupon with the processing that has been illustrated in the video recording action, therefore omit its explanation.

When having accomplished content 2 is recorded regional 2 last times, the residue of the content 2 in the title management information that is write down in the title management area of rear end control part 240 with the dish 1 of storage part 280 is transcribed number of times and is deducted 1.The residue of the content 2 in the title management information that is also write down in the title management area with the dish 2 of storage part 280 in addition, is transcribed number of times and is added 1.Thus, shown in Figure 20 (b), the residue of content 2 is transcribed number of times and is become " 8 " in dish 1 the title management area, transcribes number of times and becomes " 1 " and coil in 2 the title management area residue of content 2.

In addition, shown in Figure 20 (a), in the drive division 300, therefore the synchronous regime of content recorded 2 is not to represent not synchronous information on the zone 2 because dish 2 is packed into.

< registration of my dish is removed >

Next, my registration of dish remove is handled described.Receive the management information of drive control part 320 deletion records in storage part 340 of removing indication from the registration of user's dish 1, this management information is used for managing and the dish 1 corresponding zone that will remove registration.That is, delete medium id information, media key information and map information in the clauses and subclauses, and distribute labels is become " 0 ", expression does not distribute.In addition, in the zone, record under the data conditions, recorded data is also deleted.Thus, the clauses and subclauses in the storage part 340 become the state of the dish that can set up new registration procedure me.

In addition, receive the title management information deletion that the rear end control part 240 of removing indication from the registration of user's dish 1 is also write down in the title management area with the dish in the storage part 280 1.Thus, in rearward end 200, become and to discern the title that expression is recorded in the content on the dish 1.

(utilization of the file system of my dish)

In recorder device 100, write data and fetch data to the CD of the dish that is registered as me and preferably utilize the file system of obtaining from the CD of the dish that is registered as me from optical disk reading.

Here, with reference to (a)～(c) of Figure 21, following explanation is carried out in the data management of the file system of having utilized CD.(a)～(c) of Figure 21 is the figure that the data management of file system has been used in expression; Figure 21 (a) expression is recorded in an example of the file system in the storage part 280; The corresponding relation of the recording status of the corresponding dish 1 of content record state in Figure 21 (b) expression and regional 1, Figure 21 (c) are the figure of the mapping table of each file of expression.

Usually, record in the CD for each disc types, utilize this document system, each file and the address correlation of each file of record that are recorded on the CD according to the file system that standard determined.In addition, file system is recorded in the beginning part in video disc recording zone mostly.

In rearward end 200,, become that data read is got or data write the address of the CD of object with appointment with reference to the file system of obtaining from CD.When having packed CD into, file system and medium ID etc. is together obtained, and is kept in the volatile memory of rearward end 200.And, in order to tackle situation such as unexpected outage, the file system of being obtained also is kept at (Figure 21 (a)) in the storage part 280.When packing CD into, rearward end 200 is just obtained file system from CD at every turn, and the file system of record in the file system of being obtained and this device is compared, and keeps the up-to-date state of file.

Promptly; Rearward end 200 is through to comparing from the file system that CD read of the dish that is registered as me and the file system (file system that reads from this CD recently) that has been recorded in the storage part 280; Thereby obtain be recorded on the CD but be not recorded in the content in the storage part 340 information (for example, write down the CD of this content the address, represent the heading message of this content etc.).

In addition, only show among Figure 21 (a) and coil 1 relevant file system, but the quantity of the file system that is write down in the file system management zone of storage part 280 is equivalent to be registered as the quantity of dish of my dish

Thereby; The file system of the CD of the dish through will being registered as me records in the storage part 280; Even thereby under the state of the CD of not packing into, rearward end 200 also can the file system of reference record in storage part 280 be come the file on the virtual disk reflection is carried out access.That is to say,, also can as my dish of having packed into, handle data even under my situation of dish of not packing into.For example, when recording in the map information of storage part 340 when becoming the address of the corresponding storage part 340 of virtual address of access object, can utilize the address of storage part 340 to read recorded data on this address.

And; Like (b) of Figure 21 with (c); Content 1 is divided into a plurality of clip file and is recorded on the CD; Even under these circumstances, rear end control part 240 also can exactly content 1 carry out access through the configuration information of the content 1 in the file system of reference record in storage part 280.

Like this, in this embodiment, what be recorded in that map information in the storage part 340 representes is the configuration information of each content, but more precisely, shown in Figure 21 (c), expression be the configuration information of each zone (file).

In addition, when my registration of dish was removed, the file system that is recorded in the file system management zone was also deleted with title management information in the lump.

< the demonstration example of display device >

At last, with reference to Figure 22, to display device that recorder device 100 is connected on content explain as follows with the demonstration example that is recorded in the information in the header list.Figure 22 is the content of representing briefly on the display device 500 and the figure that is recorded in the demonstration situation of the information in the header list.

When the user showed header list via operation inputting part indicating recorder device 100, that kind shown in figure 22 on the display device 500 showed header list and content.

Promptly; Shown in figure 22, the display frame on the display device 500 is divided into content display part 510 and header list display part 520 these two pictures, wherein; In content display part 510, be shown to the content of watching so far constantly, in header list display part 520, show header list.

Shown in figure 22, in header list display part 520, show and registered my the corresponding label of dish.User by selecting wants to confirm my label of dish of header list, thus in header list display part 520 selected my header list of dish of explicit user.That is the information of the title admin table of displayed record in the title management area of each my dish of storage part 280.

Header list when the label of selective pan 1 has been shown among Figure 22.At this moment, be preferably in the information (icon) of the selected dish of data representing in the display part 530.In addition, selected under the situation of each title of demonstration in the header list display part 520, be preferably in the thumbnail of the content that shows in the display part 530 that the interim title of selecting is represented the user.

< the content deletion under my state of dish of not packing into >

More than the content deletion under my state of dish of having packed into handled be illustrated, but here, with reference to (a) of (a)～(c)～Figure 26 of Figure 23 with (b) my the state content down of dish of not packing into is deleted processing and explains as follows.

At first, with reference to (a) of Figure 23 (a)～(c) and Figure 24 and (b) to from my dish and storage part 340 the two situation of deletion content explain as follows.

(a)～(c) of Figure 23 is each storage part of expression has been deleted the state of content 1～3 o'clock under dish 1 the state of not packing into figure; Wherein, The corresponding relation of the recording status of the corresponding dish 1 of recording status of the content in Figure 23 (a) expression and regional 1; Figure 23 (b) is the figure that the mapping table of content 1～3 o'clock has been deleted in expression, and the title admin table of content 1～3 o'clock has been deleted in Figure 23 (c) expression.

Indicate under the situation of the content 1～3 shown in deletion Figure 23 (a) delete instruction of 240 pairs of drive division 300 output contents 1～3 of rear end control part the user.At this moment, rear end control part 240 utilizes the address that appointment is carried out in the zone of coiling on 1 to drive division 300 output delete instructions.In addition, in this example, for simplicity, put down in writing and deleted content 1～3 simultaneously, but in fact also can delete content 1～3 successively.

The dish 1 owing to do not pack into; Therefore receive that the drive control part 320 in the drive division 300 of delete instruction changes the address of reading on the storage part 340 with reference to the address on mapping table the dish 1 that rear end control part 240 is specified, and the content 1～3 of deletion record in the zone 1 of storage part 340.

In addition, drive control part 320 will coil the also deletion in the lump of information of the memory mapped in 1 the mapping table.Simultaneously, drive control part 320 makes the delete flag in the content 1～3 after the deletion become " 1 " shown in Figure 23 (b).For not deleted content 4, delete flag still is " 0 ".

In addition; Owing in above-mentioned action is handled, do not use delete flag; Therefore up to the present delete flag is not described for simplicity, but can be when carrying out above-mentioned action and handle yet, with delete flag be recorded in the storage part 340 each is content associated.

In addition, control part 240 bases in rear end are also deleted the title 1～3 in the title management area of storage part 280 from the deletion indication of user's content 1～3.Thus, under dish 1 the state of not packing into, can not carry out access to content 1～3, and title 1～3 that also can data representing content 1～3.Therefore, at this constantly, seem that content 1～3 is deleted from the user.In addition, in this example, will represent that also the title of content 1 is designated as title 1.Equally, the title with expression content 2～content n is designated as title 2～title n.

Then, in the time of in my dish is packed drive division 300 into, whether drive control part 320 judgements are " 1 " with the corresponding delete flag of each content that is documented in the mapping table.And, when existing delete flag to be the content of " 1 ", judge whether this content is recorded in my dish.That is, here, drive control part 320 judges whether delete flag is recorded in the dish 1 for the content 1～3 of " 1 ".

The content 1～3 that becomes " 1 " in delete flag is recorded under the situation in the dish 1, the content 1～3 of drive control part 320 display disc drive divisions 330 deletion records in dish 1.Then, the content 1～3 of 330 pairs of indication deletions of dish drive division is deleted.

In addition, drive control part 320 information that will be stored in the virtual disk mapping in the mapping table of the dish 1 in the storage part 340 is also deleted.Certainly, delete flag is also together deleted with the information of virtual disk mapping.

Thus, shown in Figure 24 (a), from coil 1 with virtual disk reflection also delete content 1～3, and as Figure 24 (b) shown in, the information that the virtual disk of deletion memory mapped shines upon.(a) of Figure 24 and (b) be each storage part of expression at the figure of the state that coils at 1 o'clock that packed into, the corresponding relation of the recording status of the corresponding dish 1 of recording status of the content in Figure 24 (a) expression and the zone 1, Figure 24 (b) are packed into the figure of the mapping table that coils at 1 o'clock of expression.

In addition, the content 1～3 that becomes " 1 " in delete flag is not recorded under the situation on the dish 1, and drive control part 320 is judged as in other recorder device from coiling 1 with content 1～3 deletion.Thereby drive control part 320 only will be stored in the information and the delete flag of the virtual disk mapping in the mapping table of the dish 1 in the storage part 340 and delete.

(reservation is set in the deletion outside the annotation management)

In the above-mentioned action, utilize and the corresponding delete flag of each content, judge at the dish of packing into whether deleted content at 1 o'clock.That is, when recorder device 100 has been deleted content under my state of dish of not packing into, set the deletion reservation, promptly when packing my dish into, from my dish, delete content next time.

Yet the deletion reservation of content is not limited to utilize delete flag to manage certainly.For example, storage part 340 also can be deposited script file (command file), and this script file (command file) is recorded and narrated the order that the data in the zone on my dish are deleted, and when having packed my dish into, carries out the order of recording and narrating in this script file.

Situation to be under the state identical with the processing of (a)～(c) expression of using above-mentioned Figure 23 describes as example.Indicate under the situation of deletion content 1～3 delete instruction of 240 pairs of drive division 300 output contents 1～3 of rear end control part the user.At this moment, rear end control part 240 utilizes the address that appointment is carried out in the zone of coiling on 1 to drive division 300 output delete instructions.

The dish 1 owing to do not pack into; Therefore receive that the drive control part 320 in the drive division 300 of delete instruction changes the address of reading on the storage part 340 with reference to the address on mapping table the dish 1 that rear end control part 240 is specified, and the content 1～3 of deletion record in the zone 1 of storage part 340.In addition, drive control part 320 will coil the also deletion in the lump of information of the memory mapped in 1 the mapping table.

Here, 320 pairs of script files that leave in the storage part 340 of drive control part are recorded and narrated the order of deleting by the data in the zone of rear end control part 240 appointments, to replace such setting delete flag as Figure 23 (b) shown in.That is, drive control part 320 generates the delete list that is recorded in the content 1～3 on the dish 1.

Then, when dish 1 when packing drive division 300 into, drive control part 320 just reads script file from storage part 340, and carries out the order that the script file that read is recorded and narrated.That is, drive control part 320 is carried out from coiling the order of 1 deletion content 1～3.

After receiving fill order, dish drive division 330 is from coiling 1 deletion content 1～3.Thus, the same before with it, become like (a) of Figure 24 with the content 1～3 (b) from coiling 1 and regional 1 state all deleted the two.

In addition, the order that script file is recorded and narrated is not limited to from my dish, to carry out the order of content deletion, also can be the order of carrying out the content deletion from storage part 340 and my dish the two.In this case, when in script file, having recorded and narrated order, the user temporarily can't carry out access to the content of specifying deletion.When receiving, also can from script file, delete the order of being recorded and narrated, and not carry out the content deletion from user's deletion cancellation instruction.

< advantage of recorder device 100 >

In the drive division 300 that recorder device 100 is possessed; When getting access to the delete instruction that the content in the regulation zone on the dish that is recorded in me is deleted; To with storage part 340 that this zone is associated on the zone in content recorded delete, and set the deletion reservation of this content.Then, when having packed my dish into, the content of deletion reservation has been set in deletion from my dish.

Thus, in the drive division 300 that recorder device 100 is possessed,, also can delete content as my the dish that kind of having packed into even under my situation of dish of not packing into.

(only from storage part 340, deleting content)

Up to the present, to from storage part 340 and my dish the two situation of deletion content be illustrated, but also can only from storage part 340, delete content, and in my dish, keep.From the situation of storage part 340 deletion contents, for example can think has the recording capacity of storage part 340 situation littler than the recording capacity of my dish as only, i.e. the clear area of storage part 340 situation about tailing off.

In this example, with reference to (a) of Figure 25 (a)～(c) and Figure 26 and (b) to deletion content from storage part 340 but the situation of the content of not deletion record in my dish explain as follows.

Indicate under the situation of the content 1～3 shown in deletion Figure 25 (a) delete instruction (first delete instruction) of 240 pairs of drive division 300 output contents 1～3 of rear end control part the user.At this moment, rear end control part 240 utilizes the address that appointment is carried out in the zone of coiling on 1 to drive division 300 output delete instructions.

Here, whether deletion record is in the content 1～3 of coiling in 1 for drive control part 320 inquiry rearward end 200

In this example, for this inquiry, control part 240 indication drive divisions 300 in rear end are held the record in dish 1 for content 1 and content 3, and only delete from coiling 1 for content 2.That is, 240 pairs of drive division 300 output orders of rear end control part (the 3rd delete instruction) make not to be deleted from coiling 1 for content 1 and content 3, and exports for content 2 from coiling the instruction (second delete instruction) of deletion 1.

Receive from the drive control part 320 in the drive division 300 of the indication of rear end control part 240 shown in figure 25ly,, make and preserve mark and become " 1 ", make delete flag remain " 0 " for content 1 and content 3.On the other hand,, make delete flag become " 1 ", make the preservation mark remain " 0 " for content 2.

In addition, rear end control part 240 for the title management area of storage part 280 in the title 1 of expression content 1 and content 3 and title 3 relevant information, shown in the title 3 among Figure 11 (c), only deletion and remain the number of times information relevant of transcribing with synchronous regime.For with the relevant information of title 2 of expression content 2, shown in Figure 23 (c), delete all information constantly at this.

Then, in the time of in my dish is packed drive division 300 into, whether the corresponding preservation mark of each content in drive control part 320 judgements and the mapping table is " 1 ", and whether delete flag is " 1 ".

When exist preserving when being labeled as the content of " 1 ", though preserve be labeled as " 1 " content record in my dish, drive control part 320 is not deleted content yet from my dish.On the other hand, when existing delete flag to be the content of " 1 ", if delete flag be the content record of " 1 " in my dish, then drive control part 320 is deleted this content from my dish.

That is, in this example, drive control part 320 is not preserved the content 1 and 3 that is labeled as " 1 " from coiling to delete 1.On the other hand, because delete flag is the content that is recorded in the dish 1 for the content 2 of " 1 ", therefore from coiling deletion 1.

In addition, drive control part 320 information that will be stored in the virtual disk mapping of the content 2 in the mapping table in the storage part 340 is also deleted.Certainly, delete flag is also deleted with the information of virtual disk mapping

Thus, shown in Figure 26 (a), only from coil 1 with virtual disk reflection deletion content 2, then do not delete for content 1 and content 3.In addition, shown in Figure 26 (b),, do not delete for the information of virtual disk mapping although deleted for the preservation mark and the delete flag of content 1 and 3.

Thereby, the content that can reset when content 1 becomes only in dish 1 is packed recorder device 100 into content 3.On the other hand, delete, therefore can not reset because content 2 is videoed and coiled 1 from virtual disk.

(a) of Figure 26 and (b) be each storage part of expression at the figure of the state that coils at 1 o'clock that packed into, the corresponding relation of the recording status of the corresponding dish 1 of recording status of the content in Figure 26 (a) expression and the zone 1, Figure 26 (b) are packed into the figure of the mapping table that coils at 1 o'clock of expression.

In addition, the content 1 that becomes " 1 " at the preservation mark is not recorded under the situation on the dish 1 with content 3, and drive control part 320 is judged as in other recorder device and has deleted content 1 and 3 from coiling 1.Thereby drive control part 320 will be stored in the information and the delete flag of the virtual disk mapping in the mapping table of the dish 1 in the storage part 340 and delete.

In addition, drive control part 320 notice rearward end 200 are from coiling deletion content 1 and 31.The information that the title 1 of notified rear end control part 240 deletion and expression content 1 from coil 1 title management area and the title of representing content 33 are relevant.

As stated, in the recorder device 100, can pack dish 1 o'clock into, for delete flag for the content of " 1 " from coiling deletion 1, the content that is labeled as " 1 " for preservation is then from coiling deletion 1.

Thus, for example, the recording capacity in the zone 1 of storage part 340 than the little situation of the recording capacity of my dish under, can guarantee the recording capacity in zone 1, and the content of not deletion record in my dish.
