The personage who knows this skill should understand, the data burning speed of light memory device 350 is that the data faster than multi-medium data generation device 340 far away produce speed, so, the data burning flow process of the data that cushioned at present can one extremely short during in finish, in the present embodiment, in the time of before light memory device 350 beginning data burning flow processs, first impact damper 310 and second impact damper 320 all are used as the usefulness of data buffering, thus, the number of point of contact just can reduce, in brief, present embodiment discloses the number that is used for reducing point of contact that makes of optimization first impact damper 310 and second impact damper 320.
See also Fig. 5, Fig. 5 is the data buffering view of first impact damper 310 and second impact damper 320 shown in Figure 3.Critical value supply 333 provides the first critical value TH1 and the second critical matter TH2 to first impact damper 310 and second impact damper 320 respectively, in the time of at the beginning, multi-medium data generation device 340 produces input data Din ' when time T 0, then, the input data Din ' that data storing control module 331 just will receive is buffered in first impact damper 310, when time T 1, the data total amount that is buffered to first impact damper 310 arrives the first critical value TH1, at this moment, data storing control module 331 just is buffered to second impact damper 320 with received input data Din ', please note, the data total amount that is buffered to first impact damper 310 does not also surpass the first critical value TH1, does not allow data write so data forward control unit 332 also can not activate.As shown in Figure 5, when time T 2 ', the data total amount that is buffered to second impact damper 320 arrives the second critical value TH2, yet, if second impact damper 320 continues buffering input data Din ', the data total amount that is buffered to second impact damper 320 will be above the second critical value TH2 when time T 2, therefore data forward control unit 332 just can activate the data that will be stored in second impact damper 320 and be transferred to first impact damper 310, clearly, receiving after the data of second impact damper, 320 outputs, the data total amount that is buffered to first impact damper 310 also can surpass the first critical value TH1 when time T 2, similarly, the data that data forward control unit 332 just begins to be stored in first impact damper 310 are transferred to light memory device 350, so, the data burning flow process is just when time T 2, and the data that light memory device 350 can burning first impact damper 310 outputs on a discs.
As shown in Figure 5, second impact damper 320 is cleared when time T 3, and in addition, the data total amount that is buffered to first impact damper 310 also begins to reduce, and first impact damper 310 can be cleared when time T 4.Because there are not data to continue to be buffered to first impact damper 310, so the data burning flow process can be interrupted when time T 4, and light memory device 350 produces a point of contact followed by meeting, as mentioned above, the data burning speed of light memory device 350 is that the data faster than multi-medium data generation device 340 far away produce speed, therefore, when time T 5, light memory device 350 stops data burning, multi-medium data generation device 340 produces input data Din ', and data storing control module 331 cushions the first vacant up till now impact damper 310 of input data Din ' that receives.
As shown in Figure 5, in second impact damper 320, fill up data before second critical value, first impact damper 310 can be filled up to first critical value earlier, and only all fill up separately after data reach separately critical value at first impact damper 310 and second impact damper 320, the data burning flow process just can activate, so, in each time during the data burning, the total amount of burning data is much larger than the method for known techniques, because first impact damper 310 and second impact damper 320 all make full use of, so the number of point of contact just can reduce and overall data burning usefulness just can be promoted significantly.
Please note, the quality of multi-medium data (for example, HQ:Hight Quality Play, SP:Standard Play, LP:Long Play, EP:Extended Play, SLP:Super Long Play, SEP:Super Extended Play) can determination data produce speed, just, the input data speed of second impact damper 320 is the multi-medium data quality that depend on multi-medium data generation device 340, and when data generation speed is slack-off, keep for the cushion space of mismanage (error handling) also can reduce so,, thereby further reduce the number of point of contact so this first critical value and second critical value just can be set as bigger numerical value.So, the critical value supply can according to the multi-medium data quality of multi-medium data generation device 340 (for example, HQ, SP, LP, EP, SLP SEP) arranges required critical value, so to reach best usefulness.
