Fig. 2 representes to have the outside drawing of the optical disk processing system of optical disc apparatus.In cover top surface, be provided with a plurality of box C1, C2, C3, the C4 of the same capability that is used for holding optical disk 10 as the record cell 150 of optical disc apparatus.These boxes C1, C2, C3, C4 can be with respect to these supporting construction installation and removal by the support construction supports that is arranged on its back side.Under the configuration status of box C1 as shown in the figure, C2, C3, C4, box C1 as reclaiming box, as storage box, is held the untreated CD of predetermined number with box C2, C3, C4 respectively.
Clamping unit 100 clamps the center pit of CD 10, is located on the transferring arm 200.One end of transferring arm 200 is fixed on the elevating mechanism 33.Elevating mechanism 33 is supported by pillar 44,50, and the driving force of the output shaft of motor 60 is delivered to gear 70 through pulley, and this gear 70 meshes with the tooth bar 44a of pillar 44, thereby goes up and down in vertical direction, moves up and down transferring arm 200.
Sliding shoe 80 is fixed in the end of pillar 44,50, and this sliding shoe 80 is supported on the leading axle 90 slidably.And, sliding shoe 80 with set up by 110,120 on wheel be with 101 to be connected fixingly, this is with 101 to be driven by motor 130, thus pillar 44,50 and transferring arm 200 come and go mobile with sliding shoe 80 in the horizontal direction.
140 pairs of label surface by the CD 10 of optical disc tray 140a loading of printing element are printed.Record cell 150 is to CD 10 recorded informations of being loaded by optical disc tray 150a.
The processing of CD 10 is made up of control program, to handle the system processor executive control program of control system molar behavior respectively according to each box C2, C3, C4 as storage box.At first, the CD 10 that is positioned at the superiors of box C2 is clamped by CD clamping unit 100, and when being sent to printing element 140, record cell 150 successively and accomplishing predetermined processing, this CD that disposes 10 is accommodated in as the box C1 that reclaims box.CD 10 among the box C2 is handled successively, when the CD in being contained in this box C2 is used up, at this constantly, through the judgement of control program, with box C2 as reclaiming box.And, when proceeding to handle, be contained in the processing that the untreated CD 10 among the box C3 is scheduled to after, be accommodated in as among the box C2 that reclaims box.Carry out same processing afterwards repeatedly.
In addition; In above-mentioned explanation, at first print in the label surface of 140 pairs of CDs 10 of printing element, carry out the record of data afterwards at 150 pairs of CDs of record cell 10; But after also can from each box, taking out CD 10; At first be sent to record cell 150, after record cell 150 has write down data, print in 140 pairs of label surface of printing element.Also can replace printing element 140 and record cell 150 is set, at a plurality of record cells 150 to CD 10 record data alternately.
So, to a plurality of CDs successively, continuously under the situation of record data, its productivity becomes problem.To video disc recording data the time, embossment does not form under the situation of physical format information, disc manufacturer information in the control data zone, through writing in advance above-mentioned data recording to the control data zone.And, before record data, recording power is adjusted to optimum value.The adjustment of the recording power during record data is handled and is commonly referred to as OPC (OptimumPower Control, best power control).Make the multistage variation of recording power and record test data, this test data of resetting is measured the β value.And the determining recording power that will obtain target beta value is an optimal recording power.In the past, whenever to each video disc recording data the time, all carry out OPC, but the inventor finds to have at CD under the situation of same manufacturer ID (MID), along with the finish increase of the number or the number that disposes of record, optimal recording power converges to steady state value gradually.
Fig. 3 representes to be accompanied by the record number or to handle the situation that the variation of number changes through the optimal recording power that OPC obtains.A representes the recording power of OPC, and B representes the moving average of recording power, and C representes the slope of moving average.In the drawings, transverse axis representes to have the record number of the CD of identical MID, and the longitudinal axis is represented recording power and slope thereof.At the record number is under the fewer situation in 0～50 left and right sides; Promptly under the situation in the stage that can think the system start-up initial stage; The trend that deviation perhaps changes appears in the recording power that has demonstrated OPC; But after reaching about 50, recording power has demonstrated to constant value (57mW (5.70E+01)) convergent trend.This means that under the less situation of record number, each CD all need be through OPC adjustment optimal recording power, but along with the increase of record number, the deviation or the variation of optimal recording power tail off, thereby be set to roughly the same recording power and get final product.Along with the increase of record number, the situation that optimal recording power becomes stable can think that its reason is; The situation such as temperature rising that have light picker in initial start stage; And after starting through certain hour, when the record number increases, the temperature of the light picker constant and stable that also becomes.The inventor is conceived to the above-mentioned fact, and identical and record number is under the deviation of bigger value, the optimal recording power situation about diminishing at the MID of the CD that should write down, and does not carry out OPC, and directly uses the optimal recording power of last time, handles thereby simplify adjustment.
Fig. 4 representes the treatment scheme of this embodiment.At first, when inserting CD 10 (S101), the MID that the system controller 32 of optical disc apparatus is judged the CD 10 that is inserted whether with the MID identical (S102) of the CD 10 of last registration.This judgement can be carried out according to the record data that send from system side.And, also can specify from now on the MID of the CD of producing 10 in advance in system side, system controller 32 short of changes of receiving MID from system-side, it is continuous just to be judged as MID.Certainly, itself record under the situation of MID, also can read this MID, judge whether consistent with the MID of last time at CD 10.For example, in the land pre-pit LPP of DVD-R (Land Pre-Pit), except the address, only read among the regional land pre-pit LPP and contain MID, also can read this MID, judge whether its MID with last time is identical.Data such as the manufacturer name that contains CD 10 among the MID and corresponding times speed are if above-mentioned data consistent then can be regarded its CD that comes down to identical type 10 as.
Under MID and last time MID condition of different, system controller 32 is carried out common processing.That is, the CD 10 that is transported into is carried out OPC, the optimal recording power that obtains is stored in storer (S105).The optimal recording power that is stored in the storer is used to calculate moving average as shown in Figure 3 and slope thereof.And, after having set optimal recording power, carry out and write in advance, record physical format information, disc manufacturer information (MID) are (S106) in the control data zone.When writing in advance,, can also adjust focus servo gain (Focus ServoGain) and tracking servo gain (Tracking Servo Gain) except the adjustment recording power.
On the other hand, under the MID situation identical with the MID of last time, next system controller 32 judges that the deviation of optimal recording power is whether in allowed band (S103).This judgement be through moving average that is stored in the optimal recording power in the storer or amount of movement average gradient variation whether threshold value with under carry out.Difference that also can be through moving average or moving average and last sub-value whether threshold value with under carry out.In the deviation of optimal recording power not under the situation in allowed band, even identical MID also likewise carries out OPC (S105) with common processing.On the other hand, under the situation of deviation in allowed band of recording power, and then judge OPC skip continuously number of times whether at pre-determined number with interior (S104).This judgement is from following consideration: skipping under the situation that number of times reaches pre-determined number, and optimal recording power change for some reason, but still carry out record with identical recording power, thereby preferably carry out OPC for the time being again.Pre-determined number for example can be set at 20 times.Skip continuously under the situation that number of times reaches pre-determined number, likewise carry out OPC (S105) with common processing.Skipping continuously under the situation that number of times do not reach pre-determined number, do not carry out OPC, it is skipped, directly keep current optimal recording power, be the optimal recording power of last time when CD 10 is write in advance, carry out and write (S106) in advance.
So, in this embodiment, to a plurality of CDs 10 successively, continuously during record data; Judge whether the CD 10 next time should write down has the MID identical with the CD of last time 10, has under the situation of identical MID, in the deviation of optimal recording power in allowed band under this condition; Skip the execution of OPC, carry out and write in advance, can omit the part of OPC; Correspondingly execution is write in advance rapidly, improves productivity.
In addition, in this embodiment, if not identical MID; Perhaps the deviation of optimal recording power is not under the situation in allowed band; The number of times of perhaps skipping OPC has reached under the situation of pre-determined number, just carries out OPC, but also can satisfy under the situation of other conditions; Do not skip OPC, but carry out OPC.For example; Preferably; Detect under the situation of the temperature variation more than the permissible value at the temperature sensor that the temperature that detects light picker 16 is set and by this temperature sensor, under the cut situation of power supply of optical disc apparatus or optical disk processing system, or under the situation that detects damage on the CD; Do not skip OPC, but carry out OPC.
More than embodiment of the present invention is illustrated, but the invention is not restricted to above-mentioned embodiment, variety of way can be arranged.For example, in this embodiment, skipping under the situation that number of times reached pre-determined number, ending for the time being to skip and carry out OPC, but also can with whether reach pre-determined number irrespectively, under identical MID and the situation of deviation in allowed band, skip OPC.
In addition, in this embodiment, under identical MID and the situation of deviation in allowed band, skip OPC; But also can be as shown in Figure 3; Because deviation diminishes when surpassing certain record number, therefore can, identical MID and record number (perhaps handling number) skip OPC after reaching predetermined number.In addition, also can pass through the schedule time at identical MID and from start-of-record after, skip OPC.
