Abstract
After data recording in accordance with a user data recording request is complete, by recording minimum lead-out data subsequently to the user data recording end position, it is possible to maintain compatibility with a reproduction-dedicated information recording medium having a plurality of recording layers even when the user data recording is terminated in the middle of the data area. Moreover, since the lead-out data recorded is minimum, there is no need of recording lead-out data in the entire unrecorded area. Thus, it is possible to reduce the time required for taking out the disc after the user data recording.
Description
Technical field
The present invention relates to information record carrier, information recording method to DVD-dual layer-R etc. has a plurality of recording layers, the information recording carrier that has the data field that can write down recorded information in each recording layer respectively carries out the record of user data, and be used for making computing machine to carry out the information recording program that carries out the user data record in each data field of this information recording carrier, and the recording medium that writes down this program.
Background technology
As recordable type DVD dish, the DVD-R of Worm type DVD dish and the DVD+RW of rewriting type DVD dish etc. are arranged.These DVD dishes have high playback interchangeability with the special-purpose DVD dish of the playback of single-surface single-layer.Recordable type DVD dish for such extensively is used for the research and development of high speed, high capacity.
One of them, the DVD+R dish that the special-purpose DVD dish of playback of single-surface double-layer is arranged and have a single-surface double-layer of playback interchangeability is (hereinafter referred to as DVD-dual layer+R).The memory capacity of DVD-dual layer+R is 8.4Gbyte, data capacity with respect to existing individual layer DVD+R is 4.7Gbyte, have about 2 times memory capacity, the data of record can be read by the DVD player of resetting or the DVD-ROM driver of the special-purpose DVD dish of the playback of single-surface double-layer.For example, open (Japan) spy and disclose a kind of information record carrier in the 2001-126255 communique such recordable type DVD recorded information.
The special-purpose DVD dish of the playback of single-surface double-layer has the address and the ground floor of the track of the second layer to increase frontlighting path (the Parallel Track Path) mode (hereinafter referred to as the PTP mode) that ground constitutes from interior circumferential periphery equally, increase from interior circumferential periphery with the address of the track of ground floor, the address of the track of the second layer is from two kinds of track modes of backlight path (the Opposite Track Path) mode (hereinafter referred to as the OTP mode) of the inside Zhou Zengjia of periphery ground formation.
In the PTP mode, the position of the radial direction of the dish that the data field of the ground floor and the second layer begins equates, all is from physical address 30000h.In addition, (lead-out) district is derived in configuration after the data field.
In the OTP mode, the position of the radial direction of the dish that the data field of the second layer begins equates that with the position of the radial direction of the dish of the data field of ground floor end the physical address of the starting position of the data field of the second layer is with the address behind the physical address bit reversal of the end position of the data field of ground floor.Under the big or small differentiated situation of the data field of the ground floor and the second layer, this difference district is included in the leading-out zone.
For example, in the PTP dish, end address, the data field D2 of the end address D1 of the data field of ground floor and the second layer is under the situation of D1＞D2, and difference district D1-D2 is included in the leading-out zone.Like this, in a recording layer, record the zone of data, also record data in the zone of the correspondence of the second layer.
Its reason is, for example the user is when the data of playback ground floor, under the situation that the focus that reads laser in the search to destination address focuses on the second layer once in a while, if do not have record data on the second layer of same radial location then can't obtain address information, therefore, as a result of, avoided producing the problem of the data of the ground floor of can't resetting.
In addition, the logical address in the DVD-dual layer is assigned with continuously from the start address of the data field of ground floor, begins the data field start address to the second layer from the end address, data field of ground floor, and logical address is continuous.In other words, under the situation that the user resets from DVD-dual layer, specify the district of resetting, can reset and not can be appreciated that recording layer by using logical address.
On the other hand, use DVD-dual layer+R to carry out under the situation of data recording, same with the processing of resetting, the user uses logical address designated recorder district.Therefore, carry out continuously under the situation of data recording,, during end of record (EOR), continue to carry out record till the end address, data field of ground floor from the data field start address of the second layer from its opening entry of data field start address of ground floor the user.
Like this, the user can carry out data recording and not can be appreciated that a plurality of recording layers DVD-dual layer+R.
Therefore, consider that user's data is recorded in the situation about finishing of the data field of the second layer midway, does not perhaps write down and the situation of end data record fully in the second layer.For example, the data field of the second layer midway (promptly, in the data field of the second layer, exist under the state of recording areas not), the user's data end of record (EOR) situation under, become in the data field of the second layer and remained the not state of recording areas, become the dish layout (layout) that does not have interchangeability with the special-purpose DVD-dual layer dish of resetting.
In addition, for example, when the data that the user resets ground floor, the focus that reads laser in the search to destination address focuses under the situation on the second layer once in a while, if the not recording areas of record data is arranged also in the second layer of same radial location, then can't obtain address information, therefore, as a result of, the generation problem of data of ground floor of can't resetting.
Such problem produces under the situation of the data recording of end user too not writing down in the second layer fully.
Summary of the invention
The present invention finishes in view of the above problems, its purpose is to provide a kind of information recording method formula, in operation of recording for information recording carrier with a plurality of recording layers, avoid having remained not recording areas because of boutons en passant beam data record in the data field of a recording layer, therefore do not have the situation of interchangeability with the special-purpose information recording carrier of resetting, can keep its interchangeability.

Then, be used to be implemented in the information recording method formula of the information recording method of the present embodiment under the situation of record of the user data that is through with of the layer 1 shown in Fig. 3 C and Fig. 3 D and Fig. 4 C and Fig. 4 D midway based on Fig. 5 to Figure 12 explanation.
CPU13 in the optical disc apparatus 1 is stored in this information recording method formula among the ROM12 in advance, by loading (installations) program execution to the primary memory (not shown) of CPU13 when the power connection of this optical disc apparatus 1.
Fig. 5 is the process flow diagram that is used to illustrate the processing of the method for record derived data under the situation of the record that is implemented in layer 1 the user data that is through with midway.
Fig. 6 is used to illustrate the key diagram of main frame to the finish command Close Track/SessionCommand (CDB:5B) of optical disc apparatus 1 output.
Fig. 7 is the key diagram that is used to illustrate the end functions table of the finish command Close Track/Session Command (CDB:5B).
During the end of record (EOR) of user data, in order to keep the interchangeability with DVD-ROM, main frame is to optical disc apparatus 1 output the finish command Close Track/Session Command (CDB:5B) as shown in Figure 6.Under the situation of having exported this order, the end functions table of optical disc apparatus 1 reference the finish command Close Track/Session Command (CDB:5B) as shown in Figure 7 of present embodiment, the finish command Close Track/Session Command (CDB:5B) that resolve to receive, and judge that whether the end functions that comprises among this finish command Close Track/Session Command (CDB:5B) is the Close Function " 111 " (step S101) of order of the record request of the minimal derived data of expression.
In step S101, comprise at the finish command that receives under the situation of Close Functon " 111 " of the order of representing minimal derived data record request, judge relatively by the address whether the address location (the X position of Fig. 3 B, the X position of Fig. 4 B) of user data end of record (EOR) and the start address of leading-out zone have difference (step S102).
In step S102, be judged to be under the situation of difference, will be recorded in by the minimal derived data that 64ECC Block constitutes (step S103) after the end of record (EOR) address of the user data in the data field.After step S103 finishes, carry out the taking-up of CD 2.
On the other hand, in step S101, do not comprise under the situation of the Close Function " 111 " that is used to represent the order of minimal derived data record request being judged to be the finish command CloseTrack/Session Command from main frame, in the end of record (EOR) address of the user data from the data field to the Zone Full record derived data (step S104) of the end address of leading-out zone.After step S104 finishes, carry out the taking-up of CD 2.
In addition, comprise the Close Function " 111 " of the record request order that is used to represent minimal derived data being judged as the finish command Close Track/Session Command from main frame, and being judged as the end of record (EOR) address of the user data in the data field and the start address of leading-out zone does not have under the situation of difference, in the data field from the end of record (EOR) address of user data to the Zone Full record derived data (step S104) of the end address of leading-out zone.After step S104 finishes, carry out the taking-up of CD 2.
Therefore, under the situation of the record of the user data that midway is through with of the data field of a recording layer, therefore also then user data record derived data can keep the interchangeability with the information recording carrier of the playback special use with a plurality of recording layers (layer 0, layer 1).
In addition, in step S101, represent that at the finish command Close Track/SessionCommand the derived data of record is minimal data volume under the situation of Close Function " 111 " of minimal derived data request command from main frame.Thus, because the whole not recording areas record derived datas in the data field are just impassable, so can shorten the required time of taking-up of the CD 2 behind the user data record.
Fig. 8 is the process flow diagram that is used to illustrate another processing of the method for record derived data under the situation of the record that is implemented in layer 1 the user data that is through with midway.
Fig. 9 A and Fig. 9 B be used for illustrating from main frame output to optical disc apparatus 1 with the order (dealer's feature (vendor unique) order CDB:CB) of the not recording areas of derived data recorded data zone and the key diagram of data layout.
The CPU13 of optical disc apparatus 1 checks by RF (check) judges in the data field of the CD 2 that is inserted into whether have not recording areas (step S202) received with the situation of order (the characteristic commands CDB:CB of dealer) the record request order of the not recording areas the derived data recorded data zone, shown in Fig. 9 A and Fig. 9 B from main frame under (step S201 is a "Yes").
Its result as illustrative among Fig. 3 C or Fig. 4 C, if there is not recording areas in the data field, then is judged to be in step S202 and do not have not recording areas in the data field.For send from main frame with the not order of recording areas of derived record (the characteristic commands CDB:CB of dealer), optical disc apparatus 1 is beamed back order Complete (step S205).
Relative therewith, in step S202, check the result who has carried out affirmation by RF, be judged to be under the situation that has recording areas not in the data field, by calculating again all not in the recording areas record derived data required writing time with reference to the end address of the start address of recording areas not and leading-out zone, and be sent to main frame (step S203) writing time of the not recording areas that will calculate.
In this case, if do not have not recording areas in the data field in the CD 2 of the DVD of the single-surface double-layer that inserts optical disc apparatus 1 dish, then will be set at " 0 " writing time and main frame is transmitted data (step S203).
After main frame has been transmitted data, carry out the record (step S204) of the not recording areas in the data field with derived data.
Like this, according to present embodiment, in step S201, received with derived data record all under the situation of the not orders of recording areas (the characteristic commands CDB:CB of dealer) from main frame, since with derived data in the data field of user data not recording areas carry out record, so for example when the data that the user resets first recording layer (layer 0), in the search of destination address, the focus that reads laser focuses under the situation of second recording layer (layer 1), owing in second recording layer (layer 1) of same radial location, do not have record data, therefore can avoid the problems such as data that to reset first recording layer (layer 0).
Figure 10 is used to illustrate the process flow diagram that does not have from the processing under the situation of taking inventory command fetch of main frame.Optical disc apparatus 1 is in step S301, and under the situation of taking inventory command fetch from main frame not, to the CD 2 of the DVD dish of the single-surface double-layer that inserts, whether the inspection by RF exists the not affirmation of recording areas (step S302).
Its result shown in Fig. 3 D or Fig. 4 D, if there is not recording areas in the data field, then is judged to be in step S302 and has not recording areas in the data field.In this case, output not from main frame take inventory the background form of command fetch the time, the not recording areas in 1 pair of data field of optical disc apparatus is carried out the record (step S303) of derived data.
Relative therewith, shown in Fig. 3 C or Fig. 4 C,, then in step S302, be judged to be and do not have not recording areas in the data field if there is not recording areas in the data field.Under this situation, transfer to standby waiting status from the order of main frame.
Thereby, according to present embodiment, output not from main frame take inventory the background form of command fetch the time, the not recording areas in the data field in the CD 2 is carried out the record of derived data.Therefore, for example when the data that the user resets first recording layer (layer 0), the focus that reads laser in the search to destination address focuses under the situation of second recording layer (layer 1) once in a while, owing in second recording layer of same radial location (layer 1), do not have record data, thereby can avoid the problems such as data that to reset first recording layer (layer 0).And, since output not from main frame take inventory the background form of command fetch the time carry out the record of such derived data, therefore do not produce defectives such as the time that is used for taking out CD 2 after data recording is elongated.
In addition, the present invention is not limited to concrete disclosed above-mentioned embodiment, only otherwise break away from the scope of claim, various distortion or change can be arranged.
