Embodiment

According to disclosed optical disk recording device and control method thereof, it mainly is to come burning for the burning head in mode in batches the data for the treatment of burning, make its normality remain on the state of work, although the number of times of waiting status can improve, but each stand-by period but can disperse because of the relation of burning in batches, can not surpass the time of the critical wait of cd-rom recorder so all can shorten, thereby not have disc produces burning failure because of the time that surpasses the critical wait of cd-rom recorder situation.

Its method as shown in Figure 1, cooperate the framework signal of Fig. 2 simultaneously, cd-rom recorder includes scrambler 11, central processing unit (CPU) 12, first working area 13, second working area 14 and burning 15, it mainly moves all controls by central processing unit 12, and scrambler 11, first working area 13, second working area 14 and burning 15 is connected in regular turn.With the actual hardware framework, first working area 13 and second working area 14 are good to use buffer zone (buffer).

Steps flow chart of the present invention: step 201, the data 16 of desiring burning are encoded by scrambler 11; Step 202 is deposited these coded datas by first working area 13; Step 203 then is sent to second working area 14 with the coded data of pre-sizing in regular turn; Step 204, burning 15 only can be carried out burning by the data in second working area 14, and with the coded data burning of pre-sizing on disc 17.

Therefore, what is key point how to determine the pre-sizing of the coded data that transmits is? at first, the coding rate of supposing scrambler 11 is V1, the replication rate of burning 15 is V2, the permissible critical stand-by period TL of this cd-rom recorder, therefore, the coded data of supposing pre-sizing is D1, then the recordable time of burning 15 is D1/V2, (allow scrambler 11 replenish the amount of coded datas) after waiting for a period of time, the coded data with pre-sizing is sent in second working area 14 by first working area 13 once more, supplies burning 15 burning data to disc 17, because compared to V1, V2, the time of transmitting is quite short, thus it is ignored, because the critical stand-by period TL of cd-rom recorder, so the foregoing stand-by period is made as critical stand-by period TL, so can obtain:

D1＝V1*(D1/V2+TL)

That is to say that the time of burning 15 burning adds the time of wait (being predefined for critical stand-by period TL), must encode out the encoded data D 1 of the needed pre-sizing of burning of scrambler 11, can calculate so derive:

D1＝TL/((1/V1)-(1/V2))

Therefore obtain the coded data of desired pre-sizing when critical, so, need only first working area 13 and the D1 data are sent to second working area 14 every the TL time, can guarantee that the stand-by period of burning 15 can not surpass the marginal time.

In the practical application, can make the data between first working area 13 and second working area 14 transmit too frequent because consider the above-mentioned practice, waste too many unnecessary resource on the contrary, can consider the encoded data D 1 of N pre-sizing doubly once is sent to second working area 14, by second working area 14 data are divided into N time again and give burning 15 a burning disc 17, thereby can obtain better effect.

The above for the preferred embodiment among the present invention, is not to be used for limiting practical range of the present invention only; Be all comply with content of the present invention and spiritual equalization variations of being done and modification, be all scope of the present invention and contain.
