Description
Technical field
The present invention relates to a kind of in recordable CD, the method that surplus boundary area is effectively write down.Relate in particular to a kind of sensitizing range at the DVD-R/W CD, be that extra border zone (to call surplus boundary area in the following text) goes up when writing down, by retrieval and record position adjustment and operation note door, carrying out stable recording, thereby really improve the method that surplus boundary area is effectively write down in the CD-R of discrimination of CD.
Background technology
The DVD model is to talk defined medium type according to DVD.All CDs of DVD medium type all have general characteristic.In the situation of the DVD of simple single layer type, its physical track structure and CD are similar.That is, be the state of continuous helical type above it, the term that in the viewpoint of DVD, is known as " track " has identical meaning with the term that is known as " concave point ".
Referring to Fig. 1～Fig. 8, Fig. 1 is the sector strucre figure of CD-R; Fig. 2 is the structural drawing of the ingress area in the CD-R sector; Fig. 3 is the structural drawing of the data area in the CD-R sector; Fig. 4 is the id field structural drawing in the data area; Fig. 5 is the specific address hum pattern of the ingress area in the CD-R sector; Fig. 6 is the data structure diagram of surplus boundary area; Fig. 7 is the method for the enterprising line item of surplus boundary area in the prior art; Fig. 8 is the problem that the method that writes down on surplus boundary area in the prior art occurs.
The track of CD shown in Figure 1 generally is divided into ingress area, data area and export area from cd centre.Wherein ingress area is identical with the general structure of Fig. 2 for this, and the distribution in its actual size and each zone also has many kinds because of medium type different.The DVD medium also are divided into many kinds according to various purposes, and wherein, the track structure of DVD-R/W has single track, and individual layer, its capacity are 3.95MB and 4.7MB.
As shown in Figure 3, the logicality layout structure of the general data sector of DVD comprises RSV field, 2048 master data and EDC field of 4 bytes of IED field, 6 bytes of id field, 2 bytes of 4 bytes etc.The effect of above-mentioned id field is regional sector, and the effect of IED field is the mistake that detects id field, and the RSV field is the storage area, and the effect of EDC field is the mistake that detects whole sectors.Wherein, id field as shown in Figure 4, its physical sector number that act as 0～23 bit, 24～31 bits are sector auxiliary information.
In having the DVD of this ordinary construction, the CD of DVD-R/W type as shown in Figure 5, it has the ingress area structure.With reference to Fig. 5, ingress area comprises the information of relevant DVD-R/W, presses standard recording in each information and each start address.Wherein, there is the control data zone in start address on 2F200h, and above-mentioned control data zone continues up to the end address, and simultaneously, surplus boundary area is with the form storage 2FE00h of start address.
Above-mentioned control data zone and above-mentioned surplus boundary area comprise the physical property information of DVD CD.Above-mentioned surplus boundary area is defined as the DVD-R/W of ver2.0 in the DVD specification, its concrete structure as shown in Figure 6.
On the DVD-R/W CD, the surplus boundary area that exists between the good control data zone of prior branch and each actual data area is arranged as mentioned above.The compact disc states of record data and the very important information of using have been reflected in these zones when the identification CD.Therefore, the record in this zone is necessary, and it is interim existence the between each zone and the data area of writing down in driver, so just become sensitive portions when record.
Realize with 192ECC in the control data zone.But, though some CDs have all radio frequencies on 192ECC,, there is white space in some CDs on the 16ECC of the aft section in control data zone.As shown in Figure 7, can there be shake and land pre-pit in the control data 192ECC zone on CD.Exist the kind of these shakes and the CD of land pre-pit very many.
Generally speaking, the recording method of above-mentioned surplus boundary area is as follows.Be record on surplus boundary area, the portion of picking up just begins retrieval with the former address of surplus boundary area, after the retrieval, just operates servomechanism.In the retrieval,, will retrieve the more address of front gradually if operation overtime or shake main axle servo device is not smooth.Pattern according to shake main axle servo device is extracted land pre-pit, if run into and the similar address of target start address that will write down, carries out actual record with regard to the operation note door.
As described in advance, in the DVD-R/W CD, surplus boundary area is highstrung place when record.Between the control data zone that above-mentioned surplus boundary area constitutes when being present in optical disc data leading address PSN (physical sector number) 0 x 30000 of elder generation and production.The CD that can not extract smoothly because of the shake in each zone and land pre-pit information (temporal information of extracting with the form of shake) is a lot, therefore, will become the very high zone of mortality during record.
In the start address of surplus boundary area, as mentioned above, according to setting up the record door, the possibility of the record failure of carrying out with existing mode is very big.In addition, for there being the CD of shaking or not having land pre-pit on the previous section of surplus boundary area, under the situation that surplus boundary area is write down, owing to have the interval between the start address of data area and the surplus boundary area or write part, will produce the problem that can not write down 0 x, 30000 addresses.
Under the situation of shake that mentions in the part of above-mentioned surplus boundary area record or the CD that does not have land pre-pit, the mortality of record is very high.Because not shake will be in the problem of the record that produces the record failure on the main axle servo device or can not carry out smoothly when not having land pre-pit.In addition, promptly allow to record, also owing on the surplus boundary area previous section, not having land pre-pit or unsettled shake, as shown in Figure 8, behind record, produce at interval between the front in it and 0 x, the 30000 address date zones that in advance record is good or lost and write sign indicating number.In this case, just can not read 0 x, 30000 addresses, so that can not discern the problem of CD.
