Embodiment
Hereinafter, will describe aspect of the present invention in further detail with reference to the accompanying drawings, wherein similar reference number is represented similar element.In order to explain the present invention, embodiment is described below by reference diagram.
Fig. 1 is a view of demonstrating the form of the CD-RW that is applied to an aspect of of the present present invention.With reference to figure 1, CD-RW (hereinafter being called " CD ") is from interiorly having inner drive area (IDA) 100 outward, introducing district (LIA) 200, user data area (UDA) 300, draw-out area (LOA) 400 and peripheral driver district (ODA) 500.The user data (UD) of record such as audio/video (AV) data on the UDA 300.
The record data relevant on IDA 100, LIA 200, LOA 400 and the ODA 500 with management, reproduction and the recording operation of CD.IDA 100 has test section (TA) 600 and recorded information district (RIA) 700.TA 600 is used to write strategy (WS) study.The recorded information (RI) that the RIA700 record is relevant with the user data that records UDA 300.RIA 700 comprises a plurality of recording records blocks of information (RIB) (first to N RIB 750).Though in the example shown RIA 700 is described as comprising recording records blocks of information 750, should be appreciated that according to the others of invention, RIA 700 can comprise out of Memory, piece and/or district.
With the record of user data executive logging recording of information concurrently.Particularly, if write down the user data of predetermined quantity to UDA 300, at first the information relevant with the current user data that writes down is recorded RIB 750 as recorded information.If write down the user data of predetermined quantity afterwards in addition to UDA 300, the information relevant with the current user data that writes down is recorded RIB 750 as new recorded information.That is, in the process of recording user information, continue to upgrade recorded information.
Because recorded information is relevant with the user data that is write down, so recorded information is the key factor of reappearing user data.Therefore, if normally carried out the user data record, but abnormal RI original records or rewriting (hereinafter being called " RI record "), the then impossible reappearing user data carried out.Therefore, when finishing the record of recorded information, must determine whether normally to have carried out the record of recorded information.If determine normally to have carried out the record of recorded information, then this RIB 750 is continued on for the RIB record at a certain RIB 750.But, if do not have normal executive logging recording of information, then no longer this RIB 750 is used for the record of recorded information, and arranges next record information to come the executive logging recording of information at a certain RIB 750.
For example, if carried out the record of recorded information and determined that it is improperly, then arrange the 2nd RIB 750 to come the executive logging recording of information at a RIB 750.
Therefore, be positioned at the record that current current RIB 750 RIB 750 before that is writing down recorded information repeatedly has been used for recorded information.So, can be more used RIB750 before these be used for the record of user data.For example, if current, then repeatedly first to the 5th RIB 750 is used to write down recorded information at the 6th RIB 750 executive logging recording of informations.Therefore, can again first to the 5th RIB 750 be used for the recorded information relevant with the record of active user's data.
Because the RIB 750 that repeatedly will be positioned at before the current RIB 750 has been used for the record of recorded information, so dielectric property their dielectric property and UDA 300, that change because of the repeatedly rewrite operation of user data is similar.Therefore, be positioned at current RIB 750 RIB 750 before and have the dielectric property that is fit to carry out WS, so that more approximate by the dielectric property of overwrite UDA300 repeatedly.
Up to the present, the form of the CD that can be applicable to an aspect of of the present present invention has been described.But the example of CD have rewriteable compact disc (CD), digital video disc (DVD), Blu-ray Disc (BD), Advanced Optical Disc (Advanced Optical Discs, AODs) and HD-DVD.The CD-RW of any other type can be used for embodiments of the invention.
Similarly, should be appreciated that and other term to be used for each district of CD according to optical disc types.For example, though term RIA 700 is used for the DVD-RW shown in Fig. 1, other term comprises content regions table (TCZ) and the disc identification zone (DIZ) that is respectively applied for DVD+RW and DVD-RAM.Hereinafter, though describe, should be appreciated that and the aspect of invention can be applied to TCZ and DIZ similarly with term RIA 700.In addition,, other term can be respectively applied for DVD-RW and DVD+RW, comprise power calibration area (PCA) and inner disk test section (IDTZ) though in Fig. 1, use term TA 110.Hereinafter, though describe, should be appreciated that and the aspect of invention similarly can be applied to PCA and IDTZ with term TA 600.
Fig. 2 demonstrates the block scheme of optical recording apparatus according to an embodiment of the invention.Though be called as recording unit, and be not all to be necessary in all respects, should be appreciated that this equipment can also be carried out reproduction process in the others of invention.This optical recording apparatus learns to optimize WS by carrying out self-adaptation WS.Here, self-adaptation WS study is the interim WS study of execution in addition that takes place between the user data recording operation, thus and optimization WS.As shown in Figure 2, optical recording apparatus comprise wave detector 110, wave detector driver element 120, have impact damper 135 recording processing unit 130, reappear processing unit 140, RIA analytic unit 150, RIA inspection unit 160, WS learning region determining unit 170, controller 180 and storer 190.
Whether the RIA analysis result inspection that RIA inspection unit 160 bases are exported from RIA analytic unit 150 has normally carried out the record of recorded information, and transmits check results to WS learning region determining unit 170 and controller 180.WS learning region determining unit 170 is selected one as the WS learning region according to the RIA analysis result from 150 outputs of RIA analytic unit between RIA and TA 600.Carry out above-mentioned self-adaptation WS study in selected WS learning region.
Fig. 3 is that demonstration is a kind of according to an embodiment of the invention by carrying out the process flow diagram that self-adaptation WS learns to optimize the method for WS.With reference to figure 3, at operation S210, the WS that controller 180 storages obtain according to the WS study of carrying out in the TA 600 of CD D.More specifically, operation S210 comprises controller 180 control wave detector driver elements 120, so that wave detector 110 is at the TA of CD D
Carry out WS study in 600, and to the storer 190 storages WS that study obtains according to WS.At operation S220, controller 180 determines whether cushioned a certain amount of user data in the user data buffer 135 of recording processing unit 130.
If S220 determines to have cushioned a certain amount of user data in operation, controller 180 control wave detector driver elements 120, thus at operation S230, wave detector 110 is according to the WS user data of being stored.More specifically, at operation S230, controller 180 control wave detector driver elements 120 are so that wave detector 110 is according to the WS user data that is stored in the storer 190.
If finished the recording operation of interruptible customer data, controller 180 controlling recording information are recorded at operation S240.More specifically, at operation S240, controller 180 control wave detector driver elements 120 are so that wave detector 110 is to corresponding RIB 750 records and the relevant recorded information of institute's user data.At operation S250, RIA inspection unit 160 is according to the RI that whether checked normal recordings from RIA 700 analysis results of RIA analytic unit 150 outputs.Check result to WS learning region determining unit 170 and controller 180 transfer operation S250.
At operation S260, if determine the improper recorded information that write down, WS learning region determining unit 170 is determined the quantity of unavailable RIB.Unavailable RIB repeatedly is used to write down RI, thereby can not be used to user data.When having accumulated enough unavailable RIB, just indicated repeatedly record.So, when the quantity of unavailable RIB should carry out optimum WS if both having been indicated, and indicates unavailable RIB to form the district with dielectric property similar to the dielectric property of the UDA 300 that repeatedly is used for rewrite operation again.So, unavailable RIB itself becomes the WS learning region that is more suitable for than test section 600.On the contrary, when having accumulated unavailable RIB still less, test section 600 has the dielectric property similar to UDA300, and can be the same suitable WS learning region with unavailable RIB.
More specifically, at operation S270, WS learning region determining unit 170 is determined the quantity of unavailable RIB by using the information relevant with the RIB that is used to write down the RI that exports as the RIA analysis result of RIA analytic unit 150.For example, if write down recorded informations with the 6th RIB 750, first to the 5th RIB 750 repeatedly has been used to write down recorded information, thereby can not be used to user data.Therefore, WS learning region determining unit 170 defines 5 unavailable RIB.
At operation S280, if the quantity of unavailable RIB more than or equal to 5, is then being operated S290, WS learning region determining unit 170 selects to have the district of unavailable RIB as the WS learning region.For example, if 5 unavailable RIB (first to the 5th RIB) are arranged, then selected WS learning region is first to the 5th RIB.But although with 5 as predetermined quantity, should be appreciated that the dielectric property according to optical record medium, as the function of overwrite number of times, other quantity can be predetermined quantity.Be also to be understood that aspect, all used RIB before the WS learning region needs not be, and those of the dielectric property selected, approximate UDA 300 most possibly among the used RIB before can being according to invention.
At operation S310, controller 180 is stored the WS that obtains by execution WS study in the WS learning region of determining in operation 290, thus the WS of renewal pre-stored.Because operation S310 is identical in fact with operation S210, its description of Therefore, omited.If the quantity of unavailable RIB is more than or equal to predetermined quantity, for example 5, then explanation has repeatedly rewritten user data to the UDA 300 of CD D.That is, along with the increase of user data rewrite operation number of times, the quantity of unavailable RIB 750 also increases.The dielectric property of UDA300 is similar to unavailable RIB's 750, but not the dielectric property of TA 600.Therefore, unavailable RIB 750 is the districts that are fit to carry out WS study more, and the WS that uses unavailable RIB750 to obtain is the WS that is fit to more, will be applied to the user data record.
If less than 5, WS learning region determining unit 170 selects TA 600 as the WS learning region at operation S305 in the quantity of operating the unavailable RIB of S280.At operation S310, controller 180 is stored in the WS that obtains by execution WS study among the determined TA 600, thus the WS of storage before upgrading.This is because for this example, is not enough to carry out WS study by the shared district of unavailable RIB that is less than 5.But, should be appreciated that in the others of invention, the district shared by the unavailable RIB that is less than predetermined quantity may be enough to carry out WS, therefore except that TA 600 or replace TA 600, still unavailable RIB can be used as the WS learning region.
In addition, if the quantity of unavailable RIB is less than predetermined quantity (5 in this example), illustrate that the number of times of the user data rewrite operation of carrying out is less relatively in UDA 300.Therefore, the dielectric property of UDA 300 is similar to TA's 600, but not the dielectric property of unavailable RIB.Therefore, TA 600 is the districts that are fit to carry out WS study more usually, and the WS that uses TA 600 to obtain is the WS that is fit to more, will be applied to the user data record.But, should be appreciated that, the invention all aspect, TA 600 may not be more suitable.
After operation S310, operation S220 begins once more.That is, according at the operation S310 WS that obtains and store, be recorded in the user data that is buffered in after the operation S230 in the UD impact damper 135.Executable operations S240 is to S310, up to cushioned next user data in user data buffer 135 after operation S230 has write down user data.In other words, executable operations S240 has filled next user data up to having write down after the user data at operation S230 in the user data buffer 135 to S310.Because the high-speed data recording rate of current optical recording apparatus, this is possible.Promptly, because sometime, the amount of user data that will write down that flows out is greater than the amount of user data that flows to user data buffer 135, so optical recording apparatus has in time of a certain amount of user data of record and cushions interval between time of a certain amount of next user data.In this interim, executable operations S240 is to S310.By this way, WS is remained optimum WS, and interruption logging process not.Therefore, according to the one side of invention, when executive logging, the WS optimisation strategy is carried out WS in real time and is optimized (that is, not interruption logging process).But should be appreciated that does not need to carry out the WS optimisation strategy in real time, and can carry out between recording operation, rather than in interim of recording operation.In addition, should be appreciated that aspect, need all not carry out optimisation strategy at interval, and can in selected interval, carry out at each according to invention.
In addition, dislocation wave detector 110 needs a small amount of time with executable operations S310.This is that wave detector 110 has been positioned at the RIA 700 of CD D because when executable operations S240 and S250.In other words, because identical or very approaching at RIA 700 or the TA 600 (it is adjacent with RIA 700) of selected WS learning region execution WS, so only need a small amount of time dislocation wave detector 110 to carry out WS study at operation S310 with the RIA 700 that is used for executable operations S240 and S250 at operation S310.Therefore, according to the one side of invention, during recording process, wave detector 110 has minimum traveling time.
According to above-mentioned embodiments of the invention, the interim in the user data recording operation is carried out WS study, thereby obtains optimum WS when executive logging is operated.But, should be appreciated that and can for example in recording unit, install when having the CD D of available data first carrying out WS study At All Other Times.
In the above-described embodiments, according to whether normal recordings recorded information determine whether to carry out WS study in interim.That is, if the improper recorded information that write down is then carried out WS study in interim, and if normal recordings recorded information, then do not carry out WS study in interim.This is because the recording operation of improper recorded information may be caused by inappropriate WS.But, should not regard it as restriction.Therefore, should be appreciated that, unless beyond the normal recordings information or replace improper recorded information, can determine whether to carry out WS study according to other factors in interim.For example, can whether carry out WS study in the past according to the number of times of user data recording operation, the total amount and the set time of institute's user data.
As mentioned above, whether determine the WS learning region according to the quantity of unavailable RIB more than or equal to 5.If the quantity of unavailable RIB is less than 5, determine that TA is the WS learning region.But the quantity 5 that is used for definite WS learning region that provides for this example is arbitrary values, can use other any amount.In addition, predetermined quantity needs not be arbitrarily, and can select according to the conforming quantity between the quantity of condition that UDA 300 statistically more may be provided and unavailable RIB.
As mentioned above, the interim in the UD recording operation is carried out WS study, thereby obtains optimum WS in real time.Therefore, if obtain inappropriate WS when fixing disc D, or upgraded WS inadequately, the other WS study of executed in real time can be corrected inappropriate WS.
Though the dielectric property of UDA 300 changes owing to recording operation repeatedly, learn because in the similar RIA 700 of its dielectric property and UDA 300, carry out WS, thus can obtain optimum WS, thus the data recording performance can be improved.
Though do not require, should be appreciated that, can make jointly and be used for realizing whole or part method of the present invention being coded in computer software on one or more computer-readable mediums and one or more universal or special computing machine.
Aforesaid embodiment and advantage are example, and may not be interpreted as limiting the present invention.This religious doctrine can be applicable to the equipment of other type, and need and not reappear on two kinds of apparatus operating and carry out at executive logging.In addition, the description of embodiments of the invention is for the usefulness of demonstrating, and does not limit the scope of its claim or equivalent, and for those skilled in the art, as seen many replacements, modification and change will be distinct.
