As record reproducing mode for such dish, known CLV (Constant Liner Velocity: linear velocity is certain) mode, CAF (Constant Angular Velocity: rotating speed unanimity, past more outer circumferential side then linear velocity is fast more) mode, used ZCLV (Zone CLV) mode of CLV mode and CAV mode.
In the CLV mode,,, can guarantee big recording capacity though the control of data management and rotational speed is complicated a little owing to drive CD with certain linear velocity rotation.Conversely, when adopting the CLV mode, owing to need the interior circumferential portion of past more dish then to improve rotating speed more, so be difficult to make the optical disk high-speed rotation.In addition, owing to improve rotating speed, produce motor cost and improve, noise, vibration increase, the design of the servo-drive system problems such as difficulty that become.
In this respect, in the CAV mode, owing to drive CD with certain angular velocity (rotating speed) rotation, so the control of data management and rotational speed is easy.But in the CAV mode, recording capacity is slightly littler than CLV mode a little.In addition, in the ZCLV mode, CD is divided into a plurality of districts (zone) on radial direction, in each district, equally linear velocity is made as necessarily with the CLV mode.And, each district is changed rotational speed so that the outer circumferential side of past more CD then linear velocity is fast more.Thereby the ZCLV mode has the advantage of CLV mode and CAV mode.
But,, under the situation that will write down more at high speed, also limited as the output power of the semiconductor laser of the light source that uses in its optical disc apparatus even with ZCLV mode record.Therefore, for example under the situation of the CD that has used poor sensitivity, produce the situation that the required recording power of recording characteristic that obtains requiring surpasses the peak power output of semiconductor laser.
Therefore, usually, optical disc apparatus is before the record of beginning for CD, to becoming the CD examination write information of object.Then, optical disc apparatus is obtained optimal recording power based on the characteristic of the replay signal that the zone of writing by the examination of resetting is obtained, and undertaken this record by this optimal recording power.Thus, can obtain good recording quality.Afterwards, will obtain optimal recording power based on the replay signal in the zone of writing from examination and be called OPC (Optimum Power Control).Zone on the CD that examination when in addition, allowing OPC is write is called PCA (Power Calibration Area).
In recent years, developing recording layer is not the multiplayer optical disk that constitutes by one deck but by multilayer.As such multiplayer optical disk, except the playback special-purpose cd with concavo-convex hole (embossed pit) multiple stratification, known use organic pigment class material is as the CD of recording materials.Because organic pigment class material produces reaction because of the irradiation of light, and has the transparency (light transmission), be used as the material of multiplayer optical disk.
Following patent documentation 1) optical disc apparatus that is used for such multiplayer optical disk is carried out record reproducing is disclosed in.
Patent documentation 1) (Japan) spy opens the 2003-22532 communique
But, the multiplayer optical disk that is made of recording layer multilayer is being carried out under the situation of recording of information, the problem shown in following is being arranged.
For example, on same record surface, have in the dual layer discs of two recording layers, in the recording layer of the second layer under the situation of recorded information, see through ground floor recording layer and on the recording layer of the second layer recorded information.Thereby, be still recording status (antiradar reflectivity, high transmittance) of erase status (high reflectance, low transmittance) according to the recording layer of ground floor, thereby arrive the light beam light quantitative changeization of the recording layer of the second layer.Thus, follow the variation of light beam light quantity, be created in the problem of the optimal recording power variation that obtains among the OPC.The change of such optimal recording power becomes the reason of deterioration of recording characteristic of the recording layer of such second layer such as saltus step (jitter), error rate.

Embodiment
Referring to figs. 1 through Fig. 5 the first embodiment of the present invention is described.
The device for optical information recording of the first embodiment of the present invention is to having the cd-rom recording of information of the multiplayer optical disk of two recording layers as recordable rotary optical information recording medium.
Fig. 1 is the synoptic diagram of regional structure of the CD 100 of expression present embodiment.As shown in Figure 1, CD 100 has the double-decker that is made of recording layer (ground floor) 101 that is positioned at light picker 5 described later (with reference to Fig. 2) side and recording layer (second layer) 102, is to use the pigment medium of organic pigment class material.Fig. 1 represents to represent the section of CD 100 along the radial direction cut-out.CD 100 has information area, and this information area is by constituting with lower area: information recording area 104; Interior all PCA103 are arranged on the interior circumferential portion in the information recording area 104, and the examination when allowing OPC to handle is write; And periphery PCA105, being arranged on the outer peripheral portion outside the information recording area 104, the examination when allowing OPC to handle is write.In other words, the CD 100 of present embodiment has following state: the PCA that the examination in the time of will allowing OPC is write than information recording area 104 near the interior circumferential portion of rotation centers and more stacked away from the outer peripheral portion of rotation center for double-deck than information recording area 104.
Fig. 2 is the block scheme of expression to the structure of the disc drives apparatus 1 of CD 100 record reproducing information.As shown in Figure 2, disc drives apparatus 1 drives CD 100 by the rotary driving part rotation that comprises spindle motor 2.Spindle motor 2 is that angular velocity (rotating speed) is certain by motor driver 3 and servo component 4 drive controlling, so that can write by CAV mode or ZCLV mode.
The pulse width of setting in laser driver 7 also can be fixed, but in the present embodiment, sets pulse width by pulse configuration part 8 according to linear velocity and dish kind.Setting pulse width according to linear velocity and dish kind like this is owing to absorbed according to linear velocity and coil sensitivity different of each record mark length of kind.The dish kind can be by light picker 5 detects the replay signal during from the ad-hoc location of playback CD 100.If the dish kind is for example by any method can given disc manufacturer, then according to each manufacturer's classification, even same manufacturer also can further careful classification.More particularly, for each dish manufacturer manufacturer's identification code (dealer's sign indicating number (vender code)) of appointment is embedded in the CD 100 in advance.And then the sign indicating number embedding CD 100 that will be used for disaggregated classification is also passable.As other kind differentiating method, for example also can use the various parameters that embed CD 100 in advance.For example, under the situation that embeds recommendation power or pulse width etc., also can use it.Like this, can carry out optimum pulse width setup (Write Strategy) according to the various CDs of same manufacturer.
When data recording when receiving by I/F9 such as ATAPI or SCSI from data that main frame (not shown) transmits, data generating unit 10 outputs to laser driver 7 as the record data sequence via pulse set parts 8 with series form for the encoding process and the modulation treatment of the form of this data enforcement regulation.
When having the action that is used to control each part mentioned above, carries out optical disc apparatus 1 controller 11 of each function described later.Controller 11 is made of microcomputer, and this microcomputer comprises: the CPU of centralized control each several part (Central Processing Unit), write the fixed datas such as program that CPU carries out ROM (Read Only Memory), can write the RAM (Random Access Memory) of variable datas such as operational data etc. with freely upgrading.In addition, controller 11 is connected to nonvolatile memory 12.
The controller 11 of the optical disc apparatus 1 of present embodiment, except with track record on CD 100 before the OPC result in when record be stored in the situation in the nonvolatile memory 12, before data recording, carry out OPC among the PCA of CD 100 and handle, and ask the optimal recording power of semiconductor laser.OPC represents to obtain optimal recording power based on the replay signal in the zone of writing from examination.During execution that OPC handles, in interior all PCA103 and periphery PCA105 of CD 100, to the recording power of each piece (block) (each step) increase semiconductor laser, be equivalent to the examination write record of the specified block (for example, 10) of stipulated number simultaneously.
When such OPC handled, the examination of resetting was write the zone and is obtained replay signal RF, and obtains known opinion scale value β according to this replay signal RF.The symmetry of the amplitude up and down when this β is equivalent to that replay signal RF carried out the AC coupling.That is, if with reference to expression Fig. 3 according to the state of the replay signal RF of recording power, then (a) expression power is suitable, and (b) expression power is excessive, (c) the expression underpower.The downside of replay signal waveform is equivalent to the part that record mark forms.Although dutycycle is 50% in due course, because when power was excessive, the label side quilt is record longways, so dutycycle departs from this direction.It having been carried out AC when coupling, will be made as a by not shown crest and the detected upside amplitude of valley detection circuit, when the downside amplitude is made as b, opinion scale value β by
β=(a-b)/(a+b) expression.According to example shown in Figure 3, if as can be known suitably then β is almost 0, β becomes big if power is excessive, if underpower then β diminish.Therefore, in OPC, asking the value of β as optimal recording power is the recording power of desired value β target (for example, 0.04).
When this OPC processing execution, CD 100 is driven in rotation so that angular velocity (rotating speed) certain, tries to write by CAV mode or ZCLV mode.By such method calculating optimum recording power and the instruction of laser driver 7 being sent recording power.
Here, Fig. 4 represents the relation of recording power and opinion scale value β.Fig. 4 represents the example with the situation of variable power 10 progressive line items.The scope of recording power swing is called the OPC scope, the center power of the benchmark of this moment is called Pdef.The OPC scope has for Pdef, for example 10 grades of variations in+40% ,-30% scope, perhaps for Pdef+5mW ,-each method such as 1mW that changes in the scope of 4mW.
According to the β value of 10 points that obtain beta curve is carried out curve (secondary) and be similar to, obtain power P opc into β target.Carry out the condition in the moment that OPC handles according to temperature variation etc., Popc changes a little sometimes, asks Popc as far as possible so be preferably under usual conditions near Pdef.In addition, because Popc is many to the different situation of each CD, so also pulse width that can be corresponding with the kind of each CD (Write Strategy) is set simultaneously.
Handle with reference to the OPC in the such controller 11 of flowchart text shown in Figure 5.As shown in Figure 5, at first, the recording status (step S1) of the information recording area 104 of the recording layer (ground floor) 101 of the management information affirmation CD 100 of use replay signal RF or CD 100 before the information record.Under the situation of using replay signal RF, for example past from interior week toward interior Zhou Yidong light picker 5 on radial direction, and obtain replay signal RF, the storage positional information of light picker 5 and having or not of replay signal RF at this moment.Under the situation of the management information of using CD 100, the management information posting field to be reset (not shown), where confirmation is recorded to.
As mentioned above, after the recording status of the information recording area 104 of the recording layer (ground floor) 101 of having confirmed CD 100, carry out OPC in order to ask optimal recording power.
Record in the information recording area 104 of the recording layer (ground floor) 101 of CD 100 that (step S2 is a "Yes": the condition judgement parts) under the situation of information, interior all PCA103 to the recording layer (ground floor) 101 of CD 100 carry out OPC (step S3:OPC parts), afterwards, the interior all PCA103 to the recording layer (second layer) 102 of CD 100 carry out OPC (step S4:OPC parts).Then, the periphery PCA105 of the recording layer (ground floor) 101 of CD 100 is carried out OPC (step S5:OPC parts), afterwards, the periphery PCA105 of the recording layer (second layer) 102 of CD 100 is carried out OPC (step S6:OPC parts).
On the other hand, do not have in the information recording area 104 of the recording layer (ground floor) 101 of CD 100 that (step S2 is a "No": the condition judgement parts) under the situation of recorded information, interior all PCA103 to the recording layer (second layer) 102 of CD 100 carry out OPC (step S7:OPC parts), afterwards, the interior all PCA103 to the recording layer (ground floor) 101 of CD 100 carry out OPC (step S8:OPC parts).Then, the periphery PCA105 of the recording layer (second layer) 102 of CD 100 is carried out OPC (step S9:OPC parts), afterwards, the periphery PCA105 of the recording layer (ground floor) 101 of CD 100 is carried out OPC (step S10:OPC parts).
Like this, interior all PCA103 and the periphery PCA105 to CD 100 carries out the reasons are as follows of OPC respectively.As previously mentioned, when OPC carried out, rotation drives CD 100 made its angular velocity (rotating speed) certain, tries to write by CAV mode or ZCLV mode.Like this, under situation about necessarily writing down by angular velocity (rotating speed), the past more periphery of linear velocity then more at a high speed.But, under the situation that on-line velocity accelerates, the essential recording power that improves.Therefore, in the present embodiment, carry out OPC, obtain the optimal recording power of medium line speed by interior circumferential portion and outer peripheral portion at the information recording area 104 of CD 100.
In addition, record under the situation of information in the information recording area 104 of the recording layer (ground floor) 101 of CD 100, the recording layer (ground floor) 101 to CD 100 carries out the reasons are as follows of OPC at first.Promptly, in the information recording area 104 of the recording layer (ground floor) 101 of CD 100, record under the situation of information, carry out OPC by first recording layer (ground floor) 101 to CD 100, in the PCA (interior all PCA103 and periphery PCA105) of the recording layer (ground floor) 101 of CD 100, write under the state of information, carry out OPC for the PCA (interior all PCA103 and periphery PCA105) of the recording layer (second layer) 102 of CD 100, thus with the information recording area 104 of the recording layer (ground floor) 101 of CD 100 in record under the identical state of information and ask optimal recording power.Equally, in the information recording area 104 of the recording layer (ground floor) 101 of CD 100, do not have under the situation of recorded information, earlier the recording layer (second layer) 102 to CD 100 carries out OPC, thus with the information recording area 104 of the recording layer (ground floor) 101 of CD 100 in do not have to ask optimal recording power under the identical state of recorded information.Like this, when writing down under the identical state with information, can be in the hope of optimal recording power.
As mentioned above, after the OPC of interior all PCA103 of CD 100 and periphery PCA105 finishes, use the result who has carried out OPC at interior all PCA103 and periphery PCA105 to ask the recording power of medium line speed, thereby ask optimal recording power by method of interpolation.Then, this optimal recording power is set at the optimal recording power (step S11) of CD 100 and the record of start information (step S12).
Here, the service recorder layer be sandwich construction CD 100 with the information of angular velocity certain way record the time, with the information operation of recording time under the same terms, can use the result who has carried out OPC at interior all PCA103 and periphery PCA105, ask the recording power of medium line speed by method of interpolation, thereby ask optimal recording power.Thereby, even on-line velocity more toward periphery then under more at a high speed the situation, also can be in the hope of optimal recording power.Thus, the service recorder layer be sandwich construction optical information recording medium with the information of angular velocity certain way record the time, can keep stable recording quality.
To the information recording area 104 of the recording layer (ground floor) 101 of CD 100 midway till record under the situation of information, during to information recording area 104 recorded informations of the recording layer (second layer) 102 of CD 100, if will formerly carry out the optimal recording power set under the situation to the OPC of the recording layer (ground floor) 10 of CD 100, the best power that has carried out earlier setting under the situation to the OPC of the recording layer (second layer) 102 of CD 100 is stored in the nonvolatile memory 12 as parameter, then also can switch halfway.
Then, with reference to Fig. 6 present embodiment is described.For with first embodiment in the part that illustrates use same label with a part, and omit its explanation.The optical disc apparatus 1 of first embodiment uses CAV mode or ZCLV mode as the record reproducing mode for CD 100, but the optical disc apparatus 1 of the second embodiment of the present invention uses the CLV mode as the record reproducing mode for CD 100.
Using under the situation of CLV mode conduct for the device for reproducing recorded of CD 100, CD 100 is rotated driving definitely by linear velocity, when OPC carries out, tries to write by the CLV mode.In this case, because CD 100 and constant certain from the relative velocity of the laser beam of the semiconductor laser of light picker 5, if so record conditions such as recording power and recording impulse width once determine then needn't change in the whole surface of CD for best.Therefore, can carry out OPC, and use the optimal recording power of decision thus to carry out whole surface recording with identical linear velocity at interior all PCA103 of CD 100 or one of them of periphery PCA105.
Here, handle, describe with reference to general flowchart shown in Figure 6 for the OPC in the controller 11 of present embodiment.At first, the recording status (step S21) of the information recording area 104 of the recording layer (ground floor) 101 of the management information affirmation CD 100 of use replay signal RF or CD 100 before the information record.Under the situation of using replay signal RF, for example on radial direction, move light picker 5 and obtain replay signal RF, the storage positional information of light picker 5 and having or not of replay signal RF at this moment from interior week toward periphery.Under the situation of the management information of using CD 100, the management information posting field is reset (not shown), thereby where confirmation is recorded to.
As mentioned above, after the recording status of the information recording area 104 of the recording layer (ground floor) 101 of having confirmed CD 100, carry out OPC in order to ask optimal recording power.
Record in the information recording area 101 of the recording layer (ground floor) 101 of CD 100 that (step S22 is for being: the condition judgement parts) under the situation of information, interior all PCA103 (or periphery PCA105) to the recording layer (ground floor) 101 of CD 100 carry out OPC (step S23:OPC parts), afterwards, the interior all PCA103 (or periphery PCA105) to the recording layer (second layer) 102 of CD 100 carry out OPC (step S24:OPC parts).
On the other hand, do not have in the information recording area 104 of the recording layer (ground floor) 101 of CD 100 under the situation of recorded information that (step S22 is not for: the condition judgement parts), interior all PCA103 (or periphery PCA105) to the recording layer (second layer) 102 of CD 100 carry out OPC (step S25:OPC parts), afterwards, the interior all PCA103 (or periphery PCA105) to the recording layer (ground floor) 101 of CD 100 carry out OPC (step S26:OPC parts).
Like this, record under the situation of information in the information recording area 104 of the recording layer (ground floor) 101 of CD 100, the recording layer (ground floor) 101 to CD 100 carries out the reasons are as follows of OPC at first.Promptly, in the information recording area 104 of the recording layer (ground floor) 101 of CD 100, record under the situation of information, carry out OPC by first recording layer (ground floor) 101 to CD 100, in interior all PCA103 (or periphery PCA105) of the recording layer (ground floor) 101 of CD 100, write under the state of information, carry out OPC for interior all PCA103 (or periphery PCA105) of the recording layer (second layer) 102 of CD 100, thus with information recording area 104 at the recording layer (ground floor) 101 of CD 100 in record can be in the hope of optimal recording power under the identical state of the situation of information.Equally, in the information recording area 104 of the recording layer (ground floor) 101 of CD 100, not have under the situation of recorded information, carry out OPC by first recording layer (second layer) 102 to CD 100, can with information recording area 104 at the recording layer (ground floor) 101 of CD 100 in do not have to ask optimal recording power under the identical state of the situation of recorded information.Like this, when writing down, under the same terms, can obtain optimal recording power with information.
As mentioned above, after finishing for the OPC of interior all PCA103 (or periphery PCA105) of CD 100, the optimal recording power of obtaining is set at the optimal recording power (step S27) of CD 100 and the record of start information (step S28).
Here, the service recorder layer be sandwich construction CD 100 with the information of linear velocity certain way record the time, with the information operation of recording time under the same terms, can be in the hope of the optimal recording power of OPC action.Thus, the service recorder layer be sandwich construction optical information recording medium with the information of angular velocity certain way record the time, can keep stable recording quality.
Because in the CLV mode, inner more circumferential portion then needs to improve rotating speed more, so be difficult to make CD to reach high speed like that.And motor cost raises, and noise, vibration increase, and in addition, the design of servo-drive system is difficulty also.Therefore, replace not making rotating speed too high in interior week, and adopt the method that also not really reduces rotating speed in periphery.That is, in this case, the past more periphery of linear velocity is high more.Thereby, under these circumstances,, ask the OPC result of periphery and the OPC result in interior week, and the optimal recording power of medium line speed be set at the optimal recording power of CD 100 as illustrating among first embodiment.
Then, with reference to Fig. 7 the third embodiment of the present invention is described.Present embodiment is applied to desktop PC 50 with the present invention as signal conditioning package, except 3.5 inches floppy disks drive unit 51, also be built-in with foregoing optical disc apparatus 1 among each embodiment (can be the type that is built in one, also can be so-called internally-arranged type).Thereby main frame also is built in the personal computer 50.
According to such personal computer 50, a kind of personal computer 50 can be provided, owing to be built-in with aforesaid optical disc apparatus 1, so use as the CD 100 of multiplayer optical disk with double-deck recording layer with the recording of information action of linear velocity certain way or with the recording of information action of angular velocity certain way the time, the optical disc apparatus 1 that can be able to obtain the optimal recording power in the OPC action is as utilizations such as memory storages.
