Description
Technical field
The present invention is a kind of reproducible type CD-R writing method, refer to especially to be applied to CD writes and manifolding apparatus to the processing procedure of reproducible type CD-R.
Background technology
Since the CD writing station comes out (CD writer that promptly is commonly called as), provide the user on access data, to have great convenience, these so-called on the market CD writer are in the performance of industry at present, except to promote the speed that device itself can write faster, makes carbon copies and read, the success ratio that more writes with the raising data is as requiring on the other hand.Generally speaking can have as the discs that data write: can write formula discs CD-R (CompactDisk-Recordable), and can write formula Video CD sheet DVD-R (Digital Video Disk-Recordable), DVD-R is similar to C D-R for making the disc of a secondary data write activity in the use, and reproducible type CD-R CD-RW (Compact Disc-ReWritable) and duplicative Video CD sheet DVD-RW (Digital Video Disk-Re Writable) or DVD+RW etc. are then for repeating to write the disc of data.And generally commonly used and main discs writes pattern and has: DAO (Disc-At-Once), SAO (Session-At-Once), multi-region section write (Multi-session), TAO (Track-At-Once) and package formula and write (Packet-Writing) form etc., simply do following narration at its technology:
DAO (Disc-At-Once) is meant when writing discs, begin to write till the derivation (Lead-out) from importing (Lead-in), do from the beginning to the end data having write once, disc with this pattern making, can guarantee that the problem without any space (gap) or binding (Link) produces between rail (track) and the rail, and laser head can remain on the state of unlatching forever and its capacity of disc and master slice of duplicating can be consistent, if but generation problem in the ablation process, because all data that write are continuous and related, so might cause the data that write can't be by correct deciphering.
SAO (Session-At-Once) then is similar to the mode of DAO, the same between rail and the rail do not have a space, when using this pattern, at first can make the write activity of several rails to first section (session), laser head can take time out to then, and this moment, disc still was held open state, just allowed the CD writing station still can carry out write activity to the Unrecorded storage area of this disc after a while; The data that just can begin to do second section afterwards again writes, yet when having only a section as if a disc, then DAO and SAO do not have any difference in fact, just carry out the multi-region section just can be different when writing (Multi-session), therefore main difference is that SAO can carry out data again and write the data that DAO then can only do once and write as can be known, write pattern so utilize SAO that the multi-region section can be carried out again, and before the specification that the multi-region section writes was developed, a common section just was equivalent to a disc.
TAO (Track-At-Once) then is writing with the mode of dividing rail to carry out disc, this pattern can stay the space between rail and rail, and once can only write a rail (track), stay blank data field so write fashionable just can between rail and rail, the interruption, this design is to make that for certain buffering (buffer) space can be arranged the data that write the data field can be by complete deciphering, so in the ablation process of TAO, can do write (promptly being unit) of data field earlier with the rail, when having write the data of a rail, the laser head of CD writing station just can stop action and produce two being denoted as the block (block) that produces (Run-out), and when laser head begins to write next rail once more, can produce a binding (Link) and four blocks that change (Run-in) over to earlier, just carry out writing of data then again.
The package formula writes (Packet-Writing) and then is different from DAO or TAO isotype, can allow the data field to write with still less block (block) number, it mainly comprises dual mode: the fixed sealing packet mode writes (FPKT-Write, Fix-size PacKeT-Write) and variable package formula write (VPKT-Write, Variable-size PacKeT-Write).Write in (FPKT-Write) mode at the fixed sealing packet mode, the data field of each package (packet) must be the rail number or the block counts of same number size, and variable package formula writes (VPKT-Write) can adjust number of blocks in its package according to size of data.The same feature that binding is arranged, change over to and produce of package formula writing mode with TAO, can do continuous reading in order to the data that write at different rails, can avoid more when having defective on the disc simultaneously, the waste in the space, data field that may cause because of the pattern that writes, and produce the situation that had multidata correctly to be read when reading.
Therefore comprehensively the above does one relatively with these patterns, the package formula writes and can reduce situation about writing with read error, be because the unit that is write is little more a lot of than other pattern, can improve detecting the resolution that writes defective, but these patterns are not still with disfigurement discovery and the mechanism avoided; In addition, even if manifolding formula disc is done the action of holistic defect management (defectmanagement) and defects detection and inspection mistake, yet can getting rid of, this mode manyly may still can be used as the disc space that data write, for example cause the origin cause of formation that writes defective to be not quite similar at every turn, sometimes for the position of a certain package on the disc, itself does not damage disc, but only because other accidental reason for example shakes or the unstable write activity mistake that causes of servocontrol, just available package position is reported is defective by mistake, and causes user's puzzlement.Therefore, present problem is how to use the maximum space that writes, and save the time that writes or detect, can avoid simultaneously taking place the situation that write error and data can't be understood, and effective defects detection mechanism, hereat just become the fundamental purpose of the present invention's development in order to solve this problem.
