Fig. 4 illustrates the form that is used for the RMD 400 of sequential recordng mode according to the embodiment of the invention.With reference to Fig. 4, RMD 400 comprises RMD 410 and R tape entry tabulation 430.RMD 410 comprises: RMD identifier 411, last border inlet 413 and total number of borders 415.RMD identifier 411 is used for identification record each RMD in the RMD district.
Last border inlet 413 is about the position of the last border in all borders in the data field of single-recordng-layer write-once information storage medium 100 or double record layer write-once information storage medium 200 and the information of state.The sum on total number of borders 415 indication borders in single-recordng-layer write-once information storage medium 100 or double record layer write-once information storage medium 200.
In the present embodiment, according to the direction that the user area is used, be that unit uses single-recordng-layer write-once information storage medium 100 or double record layer write-once information storage medium 200 with the border.Last border is represented the last border of using of the direction that is used based on the user area.Therefore, having only last border can be open boundary, and the border before the last border is the closure of border.
Fig. 5 illustrates the structure according to embodiment of the invention last border inlet 413 shown in Figure 4.Last border inlet 413 comprises: the address (LRA) of the status information of the state of indication last border, the start address of last border and last record.Start address represents that the physics of last border begins the address of sector.LRA represents that data are lastly recorded in the address of the physical sector of the position in the last border.
Status information indication last border is open, thereby new data can be recorded under sequential recordng mode, or last border is that new data can not be recorded in the border that is used to reproduce wherein.Such status information only can be used for last border, and the status information of closure of border is included in the tabulation of closure of border.
Total number of borders 415 indication beginning R of last border in RMD 400 shown in Fig. 4 bring slogan into.When last border was closed, at least one the R band that is included in the last border was merged, thereby a border becomes a R band.
Fig. 6 illustrates R tape entry 430 tabulations shown in Figure 4 according to the embodiment of the invention.With reference to Fig. 6, R tape entry tabulation 430 comprises " closure of border inlet tabulation " and " the R tape entry tabulation of open boundary "." closure of border inlet tabulation " comprises first to k (k is equal to or greater than 1 variable) border inlet, and they are last open boundary inlets on the border of use before.
The R tape entry tabulation of open boundary comprises k+1 to the k+n (k and n are equal to or greater than 1 variable) R tape entry, and they are the inlets that are included in the R band in the last open boundary.First to the k border inlet each comprises the start address and the LRA on each border, and each in k+1 to the k+n R tape entry comprises the start address and the LRA of each R band.Different with the situation of last border, first does not comprise status information to k border inlet and k+1 to the k+n R tape entry.
Have only last border inlet 413 to comprise that the reason of the status information of last border is: other data are not recorded in the closure of border, and the closure of border only is used to reproduce the data of precedence record.Therefore, to be recorded in the closure of border under what logging mode be unessential to data.In addition, if last border is closed, represents that then single-recordng-layer write-once information storage medium 100 or double record layer write-once information storage medium 200 are done, and will only be used for reproducing the data that are recorded in the closure of border.
With reference to R tape entry tabulation 430, the data field of single-recordng-layer write-once information storage medium 100 or double record layer write-once information storage medium 200 comprises k closure of border, and last border is divided into n R band.As mentioned above, when last border was closed, at least one the R band that is included in the last border was merged into a R band.Thus, each closure of border comprises a R band.
Data recording and/or reproducer can be determined from total number of borders shown in Figure 4 415: the sum on border is k+1, and k+1 R tape entry is the beginning R tape entry of last border.In addition, data recording and/or reproducer can be brought slogan into based on the beginning R of the sum on border and last border and determine where the beginning R tape entry information of last border in RMD 400 is stored in.In other words, can use following equation to calculate the starting position of a R tape entry on last (opening) border among the RMD 400:
1, equation 1
1, the start address of a R tape entry on last (opening) border=(length of the RMD that takies by a border inlet) * (" sum on border "-1)+(starting position of " the closure of border inlet is tabulated ")
As mentioned above, each border has the border inlet of the start address that comprises the border and LRA.Therefore, the information that can be apace obtains about the recent file system from single-recordng-layer write-once information storage medium 100 or double record layer write-once information storage medium 200 of data recording and/or reproducer.
For example, under the situation of universal disc format (UDF) file system, the anchor point of closure of border (anchorpoint) must be following at least two 1) logic sector number 256,2) last logic sector number-256, or 3) last logic sector number.Owing under the situation of UDF file system, can learn the start address and the LRA on each border, so data recording and/or reproducer can obtain to be recorded in information where about file system apace.
In addition, when closing last border, in the end all the R bands in the border are merged in the R band of being represented by R tape entry (border inlet).Therefore, open boundary can be divided into many R bands on demand, with the service efficiency of maximization information storage medium.
For example, when the quantity of fixing and can be included in a R tape entry among the RMD 400 when the size of RMD 400 is 7000, if used 5000 R bands in first border and comprise 5000 R tape entries thus in described RMD, then 2000 R bands can be only used on second border.Yet, according to an aspect of the present invention, when the closure of border, if all R bands that are included in the described border are merged in the R band of being represented by a R band (=border) inlet, then 6999 R bands can be used in second border, have strengthened the efficient of using single-recordng-layer write-once information storage medium 100 or double record layer write-once information storage medium 200 thus.
Fig. 7 A and Fig. 7 B illustrate the data field according to the previous therein last open boundary of the embodiment of the invention is closed and new last open boundary is created.Fig. 7 A illustrates the k+1 border 570 of k closure of border and the last open boundary of conduct.K+1 border 570 as last border comprises that k R is with 571 to k+n R to be with 575.Data are recorded the second place from primary importance in the k+n R band as last R band under sequential recordng mode.
Fig. 7 B be illustrated in that the k+1 border 570 of Fig. 7 A wherein is closed and as the k+2 border 590 of new last border by open data field.The k+1 R that data are recorded in it is merged into a R band with 571 to k+n R with 575 rearmost position, to become the k+1 border.In other words, the k+1 R that is recorded in it of data becomes the k+1 border of closing with 571 starting position to the k+n R with 575 rearmost position.
