[embodiment]

Formation and effect to desirable embodiment of the present invention describes with reference to the accompanying drawings.

Fig. 2 is the internal structure figure of optical disc recording/reproducing apparatus of the present invention.

As described in Figure 2, optical disc recording/reproducing apparatus of the present invention is made up of following two parts: in CD, carry out record regenerating record regenerating portion 100, with the same external host (Host) 200 of PC (Personal Computer) of controlling it.

Assign the record or the regeneration order of given zone by above-mentioned main frame 200 to record regenerating portion 100, above-mentioned record regenerating portion 100 carries out the record regenerating of given zone according to the order of above-mentioned main frame 200.

Above-mentioned record regenerating portion 100 is made up of following components: the adapter portion 110 of recording disk data or regeneration directly particularly, receive regenerated signals from above-mentioned adapter portion 110 and be recovered to the data protocol stack 103 that signal record that desirable signal value or modulation will write down is passed on behind the signal of CD, for the correct read output signal of CD or correct tracer signal is controlled servo 140 of above-mentioned adapter portion 110 on CD, store the impact damper 120 of the regenerated signal that restores in data that will write down that above-mentioned main frame 200 passes on or the above-mentioned data protocol stack 130, be responsible for the above-mentioned record regenerating portion 100 inner microcomputers 150 that constitute the control of pieces.

The job record method of the optical disc recording/reproducing apparatus of 3 pairs of formations of process flow diagram of reference compact disk recording method of the present invention is described as follows:

At first, CD is loaded by above-mentioned video disc recording reproducing unit 100, and all management information in the above-mentioned CD all are read out, and are stored in the impact damper 120 in the record regenerating portion 100 for the moment, and these management information are applied flexibly when the record of CD.

In addition, above-mentioned main frame 200 hope in the situation of the given zone record of CD are, and are as record order, the same as 100 reception and registration of record regenerating portion with the data of the position that will write down desirable recording areas this.

After microcomputers 150 in the above-mentioned record regenerating portion 100 receive record order, the record data of storing in the above-mentioned impact damper 120 are recorded on the CD with reference to above-mentioned management information of reading.S10 at this moment, well-known technology DAD (Disc AT Once) is used in recording method, TAO (Track AtOnce), SAO methods such as (Session At Once).

The reason that can set up like this according to customer requirements or the major reason of record failure in the recording process allows record interrupt as mentioned above.

Cause external host 200 to transmit in data interruption or the record way by above-mentioned record failure major reason because the example of look-at-mes such as the multi-job of main frame or communication work is a lot.

Because the situation that such major reason causes video disc recording to interrupt, whether be the step that user's requirement is confirmed to the record interruption source.The such affirmation of step S20 forms in the microcomputer 150 of above-mentioned record regenerating portion 100.

Above-mentioned affirmation result, if the reason that above-mentioned record interrupts is not the requirement because of the user, that just investigates the number of times that Buffer Under Run (Buffer-Under-Run) takes place.Step S30

For above-mentioned Buffer Under Run being described at first, to more carefully observe the process of video disc recording reproducing unit 100 in the magnetic disc storage data, video disc recording reproducing unit 100 is passed on from main frame 200 and is received the data storage that will write down impact damper 120, and the data of the words storage of the data of what degree of storage just can be recorded in the disk in the above-mentioned impact damper 120.At this moment how many so record regenerating portion 100 carries out with the work that the data that write down in the impact damper 120 write down in CD from data writing task impact damper 120 that main frame 200 transmits the capacity of the data that usually transmit from main frame 200 together than the capacity of above-mentioned impact damper 120.

The writing task of such data carries out in the way from main frame 200 situation that transmission that aforementioned record failure major reason etc. causes data is interrupted or postponed taking place, the storage of such situation more data in impact damper 120 can not form or the storage work of data is postponed, video disc recording reproducing unit 100 writes down all data of having stored in impact damper, will produce the impact damper 120 empty Buffer Under Runs of abandoning (Buffer-under run).Such situation may appear in above-mentioned in addition Buffer Under Run: the data recording speed of comparing video disc recording reproducing unit 100 with the data transfer rate of main frame 200 is faster.

Because Buffer Under Run has appearred in such record failure major reason, check the number of times that above-mentioned Buffer Under Run occurs in the microcomputer 150 in the above-mentioned video disc recording reproducing unit 100, check whether occurrence number surpasses the error range device of having set.Step S40

Step S50 is proceeded in the situation video disc recording work of not mentioning above above-mentioned check result occurrence number surpasses the words of error range Here it is, and the words that occurrence number surpasses error device scope just can think to occur to write down failure, and this is the same with situation that interruption appears writing down in requirement according to the user.

Then and since the situation that user's requirement occurs that record interrupts or record failure major reason Buffer Under Run surpasses the error device be exactly the end of record (EOR) district according to the present invention next regional record the MSF of record position (Min, Sec, Frame).Step S60

Promptly, when the frequent appearance of above-mentioned Buffer Under Run occurrence number surpasses the error device, before the report record failure MSF of the rearmost position information of the magnetic track that write down just in time is recorded in the next zone of recording areas, occur that above-mentioned user record interrupts require the time process that finishes the MSF of the positional information of the magnetic track that has write down is recorded in the next zone of recording areas before carrying out.

At this moment, the next record district of above-mentioned recording areas in existing writing mode (SAO), mean with the zone of deriving be same position.

In addition, above-mentioned method of the present invention is the disk of record MSF information to be re-recognized know when preparing to write down, the position of the magnetic track that TOC (the Table Of Contents) information that comprises by Lead-In Area has write down with reference to the MSF information cognition of the MSF of each magnetic track and above-mentioned position of having write down is from the next regional continuously record data in the zone of the MSF of above-mentioned record failure position.Step S70

When writing down again after such record failure, from the Lead-In Area record.This is in order to append the TOC information of change, and the MSF value that writes down in the above-mentioned toc region territory is in order to keep the continuity of MSF value, and record is than the value of the MSF value increase of the magnetic track that had write down in the past.

The surface of the disk that writes down again after the compact disk recording method record of the present invention failure as described in Figure 4.

As described in Figure 4, the surface of CD is divided into following zone: the MSF district of the positional information of normal recordings and write down the leading-out zone of recorded information before Lead-In Area, the magnetic track district of record actual user data, the record record that comprises the information of the information in relevant disk or cycle (session) and magnetic track interrupts.The MSF district of the invention described above occurs as the number of times of record failure.

Above-mentioned MSF district occupies than leading-out zone (1 minute 30 seconds the end of record (EOR) signal that writes down according to the existing recording method SAO that writes, the cycle (Session) is 1 minute and 30 seconds for the first time to write situation, later 30 seconds) littler zone, in the side of the capacity of disk, can obtain an advantage.

In addition, method of the present invention is the disk that can read after the record failure with the same end of record (EOR) again of the capacity of disk permission, in order to regenerate, to collect the correct information of each recording track with reference to the MSF of the import information of each data of enclosing and minimum position information and regenerate.
