Below, will structure shown in Figure 3 be described.
Structure among Fig. 3 comprises following several sections: the spoke light sensor 11 that the speed control characteristic area beam reflected from the optical disc medium of supporting photoetching technique is detected, to the ring light sensor 10 that detects from the pattern beam reflected that is positioned at the controlling features outer ring, will be by above-mentioned each optical sensor 10, after 11 detections, the electric signal that forms after preposition amplification is handled is compared with levels of the standard (Vref), convert thereof into the section portion 12 of square wave and output then respectively, 13, the CD-ROM driver 23 of the light beam drive signal output that will produce by the tracer signal of input, the light beam irradiates that will be produced by above-mentioned light beam drive signal is to optical disc medium, then writing light beam or the reflected light that reads light beam are converted to the light picker 21 of RF electric signal, will be by the signal of above-mentioned RF electric signal according to scale-of-two (binarized) conversion, the RF portion 24 of focusing error (FE) signal and the output of tracking error (TE) signal, according to servo error signal or control signal the actuator (actuator) of above-mentioned light picker 21 is controlled, simultaneously to servo 22 of making the traction electric machine that above-mentioned light picker 21 moves and the spindle motor of the CD rotation of installation is controlled, carry out the control part 30 of photoetching action according to above-mentioned each square wave, the impact damper 31 that exchanges with information such as the data of main frame (on the figure indicate) and instructions/reply, the application program of carrying out when the photoetching technique that host computer using user provides converts the data of record format to such as pattern, be LS (Light Scribe) application program 100, and the data-switching of input become signal of video signal and the image processor 110 of its output.
In Fig. 3, though above-mentioned LS application program 100 and image processor 110 are positioned on the main frame of distinguishing from physical characteristics with pen recorder, these inscapes also can constitute an integral body with optical disc recording apparatus.
Below, will the photoetching action of being carried out by device shown in Figure 3 be described in detail.
The electronics thin slice (sheet) 101 that above-mentioned LS application program 100 will include that the user provides or pattern (101a) the CD shape selected begins to encode by bit stream from the inner ring with the corresponding scanning area of printing zone.
Fig. 4 is that the CD sheet coding that will comprise the pattern that provides forms the method synoptic diagram of photoetching with data.
In Fig. 4, shown above-mentioned coding method in detail, as can be seen from the figure, any one datum line, for example: the top perpendicular line (5a) with the electronics thin slice that includes the pattern of preparing printing is a benchmark, each virtual scanning circle (circle) (in fact scanning circle with and the virtual printing circle (circle) that has on the label surface of same magnitude of the track pitch (pitch) of the record surface of CD corresponding) generation makes bit ' 1 of pattern part ' and do not have the bit ' 0 ' forward of the pattern part corresponding bit stream of (perhaps reverse corresponding), and it is stored in the memory device, for example: it is stored on the hard disk.The circumference of each scanning circle is different.Therefore, the data volume of being distributed is also different.If the writing speed per second according to v0 when carrying out photoetching can be handled K bytes, so, the bit number (fn (Nc)) that above-mentioned LS application program 100 is distributed to each scanning circle (Nc) just can calculate by following calculating formula 1.
Fn (Nc)=8K2 π (NcLw+r0)/v0 (bits) calculating formula 1
Here, r0 represents the radius of the inner ring of printing zone, and v0 represents that optical disc medium carries out the writing speed of photoetching.In addition, Lw represents to scan the amplitude of circle, and (NcLw+r0) expression has the value of radius (r) of the scanning circle position of Nc.
That is to say, above-mentioned LS application program 100 begins to distribute the individual bit of fn (Nc) according to aforementioned calculation formula 1 to each printing circle (Nc) from the printing circle of inner ring (r0), if on the corresponding bits position, pattern is arranged, if simultaneously ' 1 ' direction on do not have bit, just according to ' 0 ' direction (perhaps reverse) by it generate photoetching with (LS uses) data 51.In this case, just can not generate data (outside the 5d) at the outer collar region (from r1 to r2) that does not have pattern.In addition, with the numbering of the scanning circle that generates at last, the number (NTOT) (it is identical with the numbering of the last scanning circle that generates) or the total amount of data (DSTOT) of generation that promptly generate total scanning circle (printing circle) of lithography data are stored.Simultaneously, the additional information that finishes storage instruction in the final data that generates.
After the instruction of sending the request photoetching to above-mentioned control part 30, just begin successively the above-mentioned LS that generates and stores to be come out with data read from memory device, and provide to above-mentioned control part 30 by above-mentioned impact damper 31 according to storage order.

In addition, if receive above-mentioned photoetching instruction, above-mentioned control part 30 is just carried out the preliminary activities such as servo setting of label surface printing.Then, the light beam that makes above-mentioned light picker 21 is to inner ring (r0) irradiation of printing zone, and then will carry out information after the buffered or data read through above-mentioned impact damper 31 by above-mentioned LS application program 100 and come out and handle accordingly.
In addition, the current location from light beam begins to regulate so that it reaches the linear velocity (v0) of regulation by the rotational speed of above-mentioned servo 22 pairs of CDs.The rotational speed of CD can maintain desirable level according to the umber of pulse in the unit interval of detecting by above-mentioned spoke light sensor 11.Simultaneously, can begin the detection case of index marker is monitored from the pattern of the signal that detects by above-mentioned ring light sensor 10.According to above-mentioned monitoring result, if confirm index marker is detected, just synchronously the LS that above-mentioned impact damper 31 receives is come out with data read with its terminal point, pattern is printed on label surface according to the value of each bit simultaneously.
That is to say, will apply to above-mentioned CD-ROM driver 23 by the tracer signal that LS produces with the value of each bit of data.Like this, just can be to printing with a corresponding pattern of printing circle.Certainly, show do not have under the situation of pattern at the bit of data, writing light beam just can not be applied in.If the data volume of current printing circle all reads out and handles by above-mentioned impact damper 31, in this case, in order to move, just the light beam of above-mentioned light picker 21 amplitude (Lw_o) according to the printing circle of having set is moved to next one printing circle.
On each printing circle pattern is printed in the manner described above, the above-mentioned impact damper 31 that LS is carried out buffered with data will become empty gradually.If underrun (underrun) takes place above-mentioned impact damper 31 or its clearance spaces surpasses specified reference value, above-mentioned LS application program 100 will be come out the LS that is stored in the memory device once more with data read, and the clearance spaces of above-mentioned impact damper 31 is filled up.In this case, with regard to generating the image data that can show, then it is applied to above-mentioned image processor 110 situation of printing with the number of the corresponding printing circle of data with the LS that moves to above-mentioned impact damper 31.In this manner, just the printing progress of the label surface of optical disc medium can be shown to the user.Again the LS that fills to above-mentioned impact damper 31 just can be recorded in the corresponding printing circle according to mode noted earlier with data.
As mentioned above, when the printing progress was shown, the photoetching carried out action can be with the end of record (EOR) command information to above-mentioned impact damper 31 transmission, when operation of recording finishes till.
In addition, Fig. 6 will be presented at instance graph on the picture at the progress msg of printed patterns on the label surface according to another one embodiment of the present invention, as shown in Figure 6, the printing progress is shown and can show not according to optical disc shapes it also can show by pattern and the printing rate that is easy to grasp its progress.
In the embodiment shown in fig. 6, above-mentioned LS application program 100 can be calculated and shows including the ratio 601 of the amount (DSTOT) of the total LS data that generate on the CD shape electronics thin slice 101 of the pattern of preparing printing with the total amount of data of transmission on above-mentioned impact damper 31, also can with total printing number of turns (NTOT) of generating on the above-mentioned electronics thin slice 101 with current on above-mentioned impact damper 31 ratio 601 of the numbering of the scanning circle (printing circle) of the data of transmission calculate and show.
In the above-described embodiments, above-mentioned LS application program 100 will be used as the data of actual print to the data of above-mentioned impact damper 31 transmission, thereby printing progress or printing rate are shown.But the meeting life period is poor before the data of above-mentioned impact damper 31 transmission carrying out actual print, and the big more above-mentioned mistiming of above-mentioned impact damper 31 is just big more.
Therefore, in order to eliminate this mistiming, in foundation another one embodiment of the present invention, the numbering (CPL_N) of the printing circle of the data that above-mentioned control part 30 just reads out from above-mentioned impact damper 31 according to 1 pair of aforementioned calculation formula confirms, then with its numbering (CPL_N) to above-mentioned LS application program 100 transmission.Like this, above-mentioned LS application program 100 just judges that the label surface that deducts 1 printing circle in the numbering (CPL_N) of the printing circle that is received finished printing process, at that printing circle (CPL_N-1) before, the situation of finishing printing shows according to the mode of Fig. 5 or Fig. 6.
