Description
Technical field
The present invention relates to device for optical information recording, optical information recording medium, light information recording method, program and computer-readable information recording medium, is sandwich construction and device for optical information recording, optical information recording medium, light information recording method, program and the computer-readable information recording medium that can carry out the information record to the optical information recording medium that its each recording layer writes down for recording layer particularly.
Background technology
Recording layer is the structure of recording medium and its recording/reproducing method of sandwich construction, for example is disclosed in (Japan) spy opens flat 11-195243 communique etc.
In addition, in the light medium of sandwich construction,, for example open in the 2002-50053 communique and be disclosed the spy to the record that each data Layer writes down the intrinsic information of this data Layer.
And then, about OPC (Optimum Power Control), for example open in the 2000-311346 communique and be disclosed the spy to the CD of sandwich construction.
Be accompanied by multimedia popularize, music CD, CD-ROM, playback dedicated medium (recording medium) such as DVD-ROM and information reproducing device be just in practicability recently.In addition, recently, except the Worm type optical disk that uses the pigment medium, use optomagnetic (MO) medium rewritable MO dish, also pay close attention to the inversion of phases medium, use the information recording/reproducing apparatus practicability of these recording mediums.In addition, rewritable dvd media is as next generation multimedia recording medium and large-capacity storage media and extensively attracted attention.
Thereby the inversion of phases medium makes recording materials reversibly become crystallization phase and no crystallization phase recorded information mutually.In addition, the inversion of phases medium is different with the MO medium, do not need the external magnetic field, can be only carry out recording of information, playback, and can carry out carrying out the record of primary information and the covered record of deletion by laser by the laser that comes the light source that free semiconductor laser constitutes.
As the general wave recording that is used in pigment type medium recorded information, for example, semiconductor laser luminescent waveform based on the monopulse of generations such as 8-16 modulation code is arranged, in monopulse record,, poultry heat produces the defective of the distortion of tears shape owing to existing record mark by this wave recording.Therefore, as the LD luminescent waveform standard that is used for recorded information on the pigment medium (scheme (strategy)), shown in Fig. 8 C, proposition passes through to form on the pigment medium based on the laser of the multiple-pulse waveform of record data such as EFM modulation code the mode of mark.The mode that the labeling section of this multiple-pulse waveform is made of front end heating pulse, follow-up a plurality of continuous heating pulse is proposed.Fig. 8 A represents channel clock, and Fig. 8 B represents the 8-16 modulation signal, and Fig. 8 C represents light wave shape.
Usually, the optimum value of the recording power when optical recording media is write down changes because of the kind of peripheral temperature or recording medium, linear velocity etc., therefore when the record that carries out for pigment medium and phase change medium, device for optical information recording is before recorded information, carry out the optimization of the recording power write by the examination that is called OPC (Optimum PowerControl, best power control).By be called the PCA of recording medium (Power Calibration Area, power calibration area) thus regulation regional record regulation information and it is reset carries out OPC.
Specifically, to the mark of 3 times of (3T)～14 times (14T) of channel clock (channel clock) period T and the test data of the compulsory figure that the space is constituted, luminous power is changed multiple class and record, this test data of resetting, thus asymmetric (asymmetry) that calculate the DC modulation of the RF signal in each power or the RF signal after the AC coupling is as metewand.Modulation M for example if the peak swing of RF signal is made as Ip-p, is made as Imax with the maximal value of RF signal, then can as
M＝Ip
-p/Imax …(1)
Calculate.
In addition, the asymmetric β after the AC coupling uses positive side wave peak level X1, the crest level X2 of minus side of the RF signal after the AC coupling, as
β＝(X1+X2)/(X1-X2) …(2)
Expression like this.Here, the positive negative peak level of RF signal is poor after ' X1+X2 ' expression AC coupling, ' X1-X2 ' expression AC coupling back FR signal peak-peak (Peak-to-Peak) value.
Then, ask best recording power based on the asymmetric β after this modulation M or the AC coupling.
In addition,, carry out under the situation of recording of information in the perhaps rewriting type medium, need to set record condition that should media type at Worm type.Here, record condition generally is meant the setting of the recording power when carrying out OPC and the setting of recording impulse shape.In the device for optical information recording side, under the situation of the kind (producing factory's name, type identification information etc.) of the medium that can determine to write down, as long as will remain in the storer in the device for optical information recording just passable in advance corresponding to these record conditions of this medium.In DVD+R or DVD+RW medium, in the swinging signal of record, what record this medium in advance produces factory's name, kind in the pre-groove (pregroove) that forms on the track record of the ADIP that is called the regulation zone (Address In Groove).
Can't determine at device for optical information recording under the situation of kind (unknown medium) of medium, owing to record the record condition of producing factory's name of specifying medium in the ADIP information in regulation zone, so determining recording power, recording impulse waveform when determining OPC based on this information.
As the method that is used for more in the past than the recorded information amount that increased optical recording media, the known technology that makes the record surface multiple stratification, in the DVD-ROM medium, record surface is that the medium of 2 layers of structure is practicability (is structure and its recording/reproducing method of the recordable media of sandwich construction about recording layer, can with reference to open flat 11-195243 communique above-mentioned spy).
And, under dielectric multi-layered situation about having changed, because recording characteristic difference in each recording layer, so need set record condition corresponding to this layer with Worm type or rewriting type.
But, can determine at device for optical information recording under the situation of kind of medium, as long as will be kept on the storer of device for optical information recording just passable in advance corresponding to the record condition of each recording layer of this media type, but can't determine at device for optical information recording under the situation of medium of the unknown of medium kind, can't carry out the setting to record condition that causes because of the difference of recording layer best, recording quality reduces.
This point, as disclosed technology in the patent documentation 2, so long as on each recording layer, record the record condition of this recording layer,, also can deal with by reading the record condition that is recorded on this recording layer even be defined as unknown medium by device for optical information recording.
But, if no matter the kind of medium, and carry out the setting of record condition by reading the record condition that is recorded on the recording layer without exception, even then be not unknown medium, under situation for the medium of the record condition that do not write down this recording layer on each recording layer, the defective that generation can't be tackled.
In addition, for example, under the situation of double deck type medium, under the situation of second layer recorded information, owing to light transmission ground floor recording layer carries out recording of information, so reaching the light quantity of the second layer is that erase status (high reflectance) or recording status (antiradar reflectivity) change according to ground floor, produce the defective that optimal recording power changes.

The following describes a mode of the best that is used to carry out an invention.
Fig. 1 is the key diagram of optical data recording/reproducing device 1 (below Fig. 2) medium (optical information recording medium) that writes down, reset of explanation one embodiment of the invention.As shown in Figure 1, this medium 101 is double-deck pigment media of recording layer 102 and 103, and the code data of DVD-ROM form uses the 8-16 modulation code to be labeled edge (mark edge) (PWM:PulseWidth Modulation) record as the data-modulated mode.Among Fig. 1,1. represent the zone that records medium information/record condition of ground floor, 2. represent the zone that records medium information/record condition of the second layer.
In addition, address information of track record etc. in the swinging signal that writes down in the pre-groove that medium 101 forms on the track record of each recording layer 102,103.
Fig. 2, Fig. 3 are respectively the block schemes of the structure of the one-piece construction of optical data recording/reproducing device 1 of explanation present embodiment and its system control device 10.
This optical data recording/reproducing device 1 is a device of implementing device for optical information recording of the present invention, uses medium 101 and record data with reference to Fig. 1 explanation, makes the semiconductor laser multiple-pulse luminous and form record mark, thereby carries out recording of information.
Optical data recording/reproducing device 1 is at the playback time of information, drive LD (laser diode) light source 2 by LD drive unit 6, make LD light source 2 luminous with playback power (reading power P r), in not shown light picker, optical element 3 via regulation, 4,5 layer 102 or 103 (with reference to Fig. 1) in the regulation of medium 101 go up and focus on the light of irradiation from the playback power of LD light source 2, and by the optical element 5 of photo detector 8 via regulation, 4,7 receive its reflected light and carry out light-to-current inversion, current signal after the conversion is carried out IV conversion and amplification by IC amplifier 9, thereby obtain replay signal (RF signal) 41.
And then, the part of the emergent light of LD light source 2 is injected via optical element 11 grades of regulation and is monitored PD (photodiode) 12, pass through IV amplifier 13 by the IV conversion with the proportional monitor electric current of luminous power, can carry out APC control by utilizing the power-monitoring signal 42 that amplifies.
When recording of information, by the pulse control signal 43 of master controller 21 generations based on the record data that constitute by the 8-16 modulation code, and drive LD light source 2 by drive current corresponding to this pulse control signal 43 by LD drive unit 6, thereby send multipulse light as shown in Figure 8, layer 102 or 103 the recording layer of the regulation by irradiation medium 101 forms record mark and carries out recording of information on medium 101.In addition, master controller 21 is in order to control the luminous level of space/peak power, and to LD drive unit 6 output offset current levels drive signals 44, crest current levels overlapped signal 45.
Then, carry out the process of recording of information processing before by optical data recording/reproducing device 1 with reference to the flowchart text of Fig. 4.
At first, master controller 21 (CPU) is in step S1, for the kinds of information that obtains identification medium 101 from the recording layer 102 of the ground floor of medium 101 record (medium information (being recorded in the zone of circle 1,2 (numeral of following such expression zone circle) of Fig. 1)), and the recording layer 102 or 103 as object is moved not shown light picker (step S1).As shown in Figure 1, in the medium 101, have the management information areas that is called the regional medium 101 of importings (Lead In) in interior all sides of the posting field of each layer 102,103,1 zone therein records swinging signal as the medium information of medium 101.Can obtain producing factory's name, being used to discern the medium information that has been endowed the media type of producing factory's name of optical data recording/reproducing device 1 by this swinging signal.Therefore, handle as the next one, in step 2,1 zone in the playback ingress area, thus from swinging signal, obtain the medium information (reading part, read step) (step S2) of medium 101.
Then, if the kind of the medium 101 by the identification of this swinging signal is by the known medium of optical data recording/reproducing device 1 (if registered in advance the ROM of master controller 21 etc.) (step S3 is a "Yes"), then with record condition (optical wavelength (optical maser wavelength) of the determining recording power when carrying out OPC, recording impulse shape set, recording light, dominant record speed etc.) decision for to each kind of medium 101 as the value (record condition obtaining section, record condition obtain step) (step S4) of table data storage in the memory storages such as ROM of master controller 21.The record condition of record is recorded in respectively on each recording layer 102,103 of this medium 101 for each kind of medium 101 among these ROM etc.
At medium 101 are not (step S3 are a "No") under the situation of the medium of the unknown of registered in advance among the ROM etc. of optical data recording/reproducing device 1, read out in the ingress area of medium 101 record condition with the swinging signal record (be recorded in Fig. 1 1., zone 2.) (record condition obtaining section, record condition are obtained step) (step S5).Record condition divide record in each recording layer 102,103 (zone that the record condition of recording layer 102 is recorded in identical recording layer 102 1., the record condition of recording layer 103 be recorded in identical recording layer 103 the zone 2. in).
Then, based on the record condition that obtains at step S4, S5, set OPC conditioned disjunction recording impulse waveform (step S6).Here, the OPC condition is meant the center performance number when changing power trace, and as the asymmetric β of target.These values, if known medium, then to each kind of this medium in advance sample plot ask the value that has most, in can the ROM of registered in advance in optical data recording/reproducing device 1 etc., but among the ROM in medium 101 is optical data recording/reproducing device 1 under the situation of the medium of unregistered the unknown, can be used as it is the value of obtaining according to the swinging signal that obtains in step 2, but preferably this is on dutyly determined with the coefficient of regulation.
Then, before recording of information action, in order to determine best recording power, and carry out OPC (step S7) at posting field and OPC zone (with reference to Fig. 1) of the recording layer 102 that will write down.
When carrying out this OPC, master controller 21 is when each handoff sectors, shown in Fig. 5 A, sector synchronizing signal 46 takes place, and when each sector synchronizing signal 46 takes place, upgrade bias level current drive signal 44, thereby shown in Fig. 5 B, the luminous power of phasic Chang LD light source 2.After the end of record (EOR) of this phasic Chang luminous power, the zone of resetting this record, and RF signal 41 is sampled in each sector, thereby carry out computing based on above-mentioned formula (2) etc. by master controller 21, calculate asymmetric β in each sector, the luminous power when deciding operation of recording by the asymmetric β that calculates.Fig. 5 A represents sector synchronizing signal 46, wave recording when Fig. 5 B represents OPC.
Like this, the execution by OPC has determined to carry out recording of information action (among the step S8) by known parts after the optimal recording power.
Like this, under the situation that the medium 101 to the unknown writes down (step S3 is a "No"), can from the ADIP information of medium 101, obtain each recording layer 102,103 pairing record condition respectively, so can in each recording layer 102,103, carry out record with the record condition of the best.But, in the ROM etc. that is optical data recording/reproducing device 1 during the known medium 101 of record (step S3 is a "Yes"), because the record condition of this medium 101 that writes down in advance among this ROM of use etc., even, also can tackle so this known medium 101 does not write down the record condition of this recording layer 102,103 in each recording layer 102,103.
In addition, also can replace the processing of Fig. 4 and carry out the processing shown in the process flow diagram of following Fig. 6.Promptly, as shown in Figure 7, as the medium 101 of the object of this situation according to the recording status of another layer 103,102 be erase status or recording status and the record condition that will be recorded in the ingress area of each recording layer 102,103 be recorded as two kinds (Fig. 7 1. ', 1. ", 2. ', 2. " each zone).In addition, the record condition of record writes down two kinds of record conditions for each recording layer 102,103 equally among the ROM of master controller 21 etc.Among Fig. 7,1. represent ground floor record the zone of medium information, 2. represent the second layer record the zone of medium information, the zone that records the multilayer record condition of the ground floor when 1. ' the expression second layer is erase status, the zone that records the multilayer record condition of the second layer when 2. ' the expression ground floor is erase status, the zone that records the multilayer record condition of the ground floor when 1. " the expression second layer is recording status, the zone that records the multilayer record condition of the second layer when 2. " the expression ground floor is recording status.
Then, under the situation of the information of carrying out record, in Fig. 6, be the processing identical with the step of Fig. 4 same numeral, so omit detailed explanation with the situation of Fig. 4.In the processing of Fig. 6, at first carrying out OPC (step S7) before, judge that another recording layer 102 in the zone of carrying out OPC or 103 same area are erase status or recording status (judging part, determining step) (step S9), corresponding therewith, one of them that use described two kinds of record conditions switched the setting content (step S6) of the conditioned disjunction recording impulse waveform of OPC.The judgement of step S9 records in ingress area etc. under the situation that the expression record finishes for example when each recording layer 102,103 has been carried out record, can judge by the information that is recorded in this ingress area etc.Perhaps, also can be undertaken by the signal level of master controller 21 judgement RF signals.
Then, when carrying out recording of information (step S8), judge that another recording layer 102 in the zone of writing down or 103 same area are erase status or recording status (this can be used as it is the judgement of step S9) (step S10), and switch recording power and led pulse waveform (step S11) in view of the above.In addition, also consider the irrelevant and certain situation of recording status of led pulse waveform and another recording layer 102 or 103, in this case, consider the action of only switching recording power.
In described explanation, be that double-deck medium 101 is that example is illustrated with recording layer, even but recording layer is three layers or its above sandwich construction, also can carry out and described same action.In addition, in described explanation, be that example is illustrated with medium 101 as the pigment medium that only can write afterwards, but for phase change medium of the rewriting that can carry out recorded information etc., thereby only also can similarly discuss, so can use the present invention by the project sequence of movement of change record condition.
