When once writing recording medium 100 is initialised when being used to use, the TDFL and the TDDS of the renewal of reading from once writing recording medium 100 are stored in the storer 3.Thereafter, if new user data is recorded, then defect management is carried out once more, create among the TDFL of control module 2 in being stored in storer 3 positional information comprise new defect cluster and with the TDFL of the new renewal of the positional information of the new corresponding replacement cluster of defect cluster, the TDFL that upgrades is recorded among the TDMA, and will indicates the pointer information of the position of writing down the TDFL that upgrades to be recorded among the TDMA.
Describe a kind ofly according to the embodiment of the invention TDFL to be recorded in method on the once writing recording medium 100 now with reference to Fig. 3, this method is carried out by data recording shown in Fig. 2 and/or reproducer.
Fig. 3 is the process flow diagram that the method for a kind of record TDFL according to the embodiment of the invention is shown.
Although be not presented among Fig. 3, when once writing recording medium 100 was loaded in data recording and/or the reproducer, initialization was performed to use once writing recording medium 100.In other words, control module 2 reads the TDFL and the TDDS of renewal from once writing recording medium 100, and TDFL and the TDDS that reads is stored in the storer 3.
Thereafter, if user data and user data record order are imported into once writing recording medium 100 from the main frame (not shown), then control module 2 records the user data on the once writing recording medium 100 with predetermined unit, and execution writes the data of back checked operation with inspection record.
During the predetermined time interval that just is being recorded when data, perhaps after finishing single data recording, data recording and/or reproducer create the positional information that comprises new defect cluster and with the TDFL of the new renewal of the positional information of the new corresponding replacement cluster of defect cluster, the TDFL that upgrades is recorded among the TDMA, and will comprises that the TDDS of the pointer information of indicating the position of writing down the TDFL that upgrades is recorded among the TDMA.
Fig. 4 is used for explaining in detail according to writing the back check handling the diagrammatic sketch of creating TDFL.Here, data are with the sector or bunch be that unit is processed.The sector is can be by the least unit of the data of the file system of computing machine or application program management.Bunch be the least unit that can once physically be recorded in the data on the dish.Usually, at least one sector is formed one bunch.
The sector is subdivided into physical sector and logic sector.Physical sector is the space of writing down therein with the dish of the corresponding data in sector.Be used to find the address of physical sector to be called as physical sector number (PSN).Logic sector is the sector location that is used for the data of managing file system or application program.Equally, logic sector number (LSN) is assigned to logic sector.
Data recording and/or reproducer use PSN to find and will be recorded in once writing recording medium 100 or the position of reproduced data on once writing recording medium 100, be used for writing down or reproducing the data computing machine or application program is that unit manages all data with the logic sector, and using LSN to find the position of data.Relation between LSN and the PSN produces according to defective and the initial position of record data is shone upon by control module 2.
With reference to Fig. 4, A represents user data area, and B represents the spare area.In user data area A and spare area B, exist PSN to be given its a plurality of physical sector (not shown)s by order assignment.LSN is assigned at least one physical sector unit.Yet except that the defect area of the user data area A that produces defective, LSN is assigned to the replacement district of spare area B.Consequently, although physical sector is identical with the logic sector size, if defect area is produced, then PSN and LSN dissimilate.
User data is recorded among the user data area A according to continuous recording pattern or recorded at random pattern.Under the continuous recording pattern, user data is by order and record continuously.Under the recorded at random pattern, user data need not be by record continuously, but by recorded at random.1. write the cellular zone that the back checked operation is performed therein to 7. indicating.
Data recording and/or reproducer record the user data in cellular zone 1. in, whether whether data recording and/or reproducer turn back to cellular zone initial and inspection user data 1. and are produced by normal recordings or defective.If produce the bunch found of defective therein, then this bunch is identified as defect cluster and is designated as defect area, i.e. defective # 1, as shown in Figure 4.
In addition, data recording and/or the reproducer user data that will be recorded among the defective # 1 re-writes spare area B.The part of the spare area B that is rewritten of user data is designated as and replaces #1 therein.Then, record the user data in cellular zone 2. in after, then whether whether data recording and/or reproducer turn back to cellular zone initial and inspection user data 2. and are produced by normal recordings or defective.If the cluster at least that produced of defective is found therein, then this at least cluster be designated as defective 2..With with above-mentioned same mode, to replace #2 accordingly designated with defective #2.In addition, cellular zone 3. in, defect area, promptly defective #3 and with defective #3 to replace #3 accordingly designated.Cellular zone 4. in, do not have defective found and do not have a defect area.
The record and check be done until cellular zone 4. after, if expectation (for example stops recording operation # 1, if the record that the user presses ejector button or distributes to the user data of recording operation # 1 is done), then create TDFL# 1 among data recording and/or the reproducer previous TDFL in being stored in storer 3, in TDFL# 1 in the 1. positional information of the defective # 1 to #3 of generation and be updated in 4. of cellular zone with positional information that defective # 1 to #3 replaces #1 to #3 accordingly.
