Description
Technical field
The present invention relates to have the record regenerator of thin compact disc of the mechanism of the optics correction that in the posture that keeps thin compact disc, is used for record regenerating, more detailed theory, relate to have by keep along thin compact disc configuration posture with and/or the tabular component used of optics correction, the record regenerator and the record regeneration method of the thin compact disc of the mechanism of generating plane swing when being suppressed at the record regenerating of thin compact disc.
Background technology
Always, in the enterprise that handles important and huge quantity data etc., be to adopt the data management system that only relies on tape or hard disk.But tape need carry out to preventing the regular maintenance of the adhesion between the tape, and this kind safeguarded the expense that cost is very high.In addition, for hard disk because driver and magnetic recording media are a pair of, thus if driver breaks down, just can not regenerate with the paired magnetic recording media of this driver on the information that writes down.Therefore, must carry out to carry out data in advance the countermeasure of mirror image etc. for the fault of defence driver, but, even take such countermeasure, in the occasion that fault has been taken place simultaneously by the dish of mirror image and original dish, or the occasion of fault has been taken place again by the dish of mirror image before the recovery of data finishes when fault takes place, the recovery of data becomes can not.
Therefore, recently, part utilization is safeguarded the data management system easy and optical recording media (CD) that reliability is high, is causing people's attention.Utilizing in the management system of CD in part, people are realizing by every means: about frequently carrying out the data of the rewriting of data, use hard disk, about visit require less the information long preservation data, use the method for CD.For CD, if can prevent because the characteristic degradation that causes of dust then need not to safeguard basically, different with the occasion of hard disk, even the driver that the supposition record regenerating is used breaks down, there is not any problem on other driver if CD moved to yet.Promptly, the needed time of malfunction elimination can be greatly shortened, the danger of losing significant data can be significantly lowered simultaneously by using CD.
Like this, CD is as safeguarding easily and the high recording medium of reliability has occupied important position, still, because the development of nearest ICT (information and communication technology) pumps up and improves the easiness of using more and increase memory capacity.Here, for increasing memory capacity, need dwindle orbital spacing (track space) and dwindle the interval of record mark.But, if the interval of orbital spacing or record mark is than some footpath λ/NA (λ: optical maser wavelength of laser, NA: the numerical aperture of aperture lens) little, because in a luminous point, enter a plurality of record marks, become and can not carry out the identification of each record mark.That is the recording capacity of CD determines its boundary by Wavelength of Laser and numerical aperture, as not taking special method, surpass this boundary and realize that high capacity is impossible.
As surpassing such upper limit, the method for high capacity CD, carried out optics supersolution picture, magnetic supersolution as mode or various trials such as super lens, holographic photography, but, as effective method, can enumerate the thickness attenuation that makes optic disc base board, increase the method for the recording capacity of unit volume.For example, as putting down in writing in the patent documentation 1～3, made up thin compact disc and for not making thin compact disc face swing stablize the record regenerator of the stabilizator that rotates by formation, can realize comparing the record regenerator of the big thin compact disc of the recording capacity several times of unit volume with CD always.Below, the CD of being made up of the thin substrate about the thickness 100 μ m that here use is called " floppy disk ".
As the additive method that uses floppy disk, remove above-mentioned such use the stabilizator, can also enumerate the size shape that uses the plane and the method for floppy disk disk-shaped glass plate support floppy disk much at one.Above-mentioned glass plate is done with the optics glass, makes laser that record regenerating uses by this glass plate irradiation floppy disk, can carry out the record regenerating interchangeability of the optical system of always optical disc recording/reproducing apparatus (guarantee and) equally with always CD.For example, present inventors confirm: if use the regeneration of commercially available DVD driver to make the center almost put the dish of the thick discoid optical flat of 500 μ m overlappingly on the thick floppy disk of the 100 μ m that duplicated the DVD pit pattern, just can carry out on above-mentioned floppy disk the regeneration as the information of pit pattern inscription.Former plate-like optical flat used herein, when supporting floppy disk, also the laser of using for record regenerating carries out the optics correction, so be called " ability of posture control hold concurrently optics revision board " below.
In using the record regenerator of floppy disk, because use the hold concurrently method constructing system more easily of optics revision board of the latter's ability of posture control, so overwhelming advantage is arranged.

But people's the checking according to the present invention is because the floppy disk rigidity is low and have static easily, so distinguished the behavior different with optic disc base board always of expressing.Here, consider that hold concurrently either party or both sides of optics revision board of floppy disk or ability of posture control have the occasion of static.When on ability of posture control is held concurrently the optics revision board floppy disk being set under such state, floppy disk all can be not smooth fully, to being in the zone (this phenomenon is called the generation gas cut) that floppy disk and ability of posture control are held concurrently and can be produced occluded air between the optics revision board.
Such gas cut can be considered to generate as following substantially.
(I) because static causes that certain part of floppy disk is bonding with the ability of posture control optics revision board of holding concurrently.
(II) because than other zones bigger electrostatic forcing is arranged at this bonding portion, its peripheral part is also bonding in succession, and bonding region is expanded gradually.
(III) along with the expansion of bonding region, floppy disk deforms, and produces because this is out of shape the part of the power of generation greater than the power that produces owing to electrostatic force.
(IV) around the part of big distortion, do not produce bonding portion, produce bonding region again in the position of leaving a little.
The following describes the occasion of gas cut such more than producing, the problem that in recording of information regeneration, produces.Under the state of common thick substrate rotation, the displacement y (t) of the z direction of principal axis of a bit (direction vertical with base plan) on substrate is represented as y (t)=δ sin ω t (δ: maximum displacement, ω: angular velocity, t: the time).
The axial acceleration a of z of this moment is commonly referred to as the face oscillating acceleration, is represented as a=y (t) "=-δ ω
2Sin ω t (getting the second differential of displacement y (t)) to time t.
Here as with decibel represent maximum displacement δ, be represented as δ=20log (a/ ω
2The 40log of)=-(f)--40log (2 π)+20log (a) (f: frequency).
About common slab substrate, the figure line of Figure 11 is represented the relation (representing with solid line among the figure) of frequency and face oscillating quantity.In the driver of record regenerator, by focus servo mechanism, follow the face of aforesaid substrate by actuator and object lens and swing (face oscillating acceleration), be controlled to be laser and correctly focus on the information faces.Above-mentioned focus servo mechanism follows face swing, the sufficient servo characteristic (representing with dot-and-dash line among the figure) that is designed to have respective frequencies in order to make actuator and object lens with having surplus.
On the other hand, be floppy disk (thin base) about 100 μ m and the ability of posture control occasion of optics revision board of holding concurrently using substrate thickness, because the face deviation of part takes place " gas cut ".Have, this gas cut remains in floppy disk even disc spins does not also disappear and ability of posture control is held concurrently between the optics revision board again.Displacement y (t) on the z direction of principal axis of any on the floppy disk of this moment is represented as:
Y (t)=δ sin ω t+ (because high order displacement that the swing of local face causes).
Because newly add on axial oscillating acceleration a of z at this moment the key element behind second in the following formula (because high order displacement that the swing of local face causes) second differential, so the face oscillating quantity of floppy disk is just expressed and the different frequency characteristic (for example representing with the dotted line in the figure line among Figure 11) of occasion of using above-mentioned common slab substrate.Therefore, using the occasion of floppy disk, than the occasion of the common slab substrate of use, the difficulty that becomes is followed in the focusing of using focus servo mechanism to carry out.
As mentioned above, using floppy disk and ability of posture control to hold concurrently in the record regenerator of optics revision board, for carrying out stable focusing, carrying out with static is that the reply of the gas cut of reason becomes important problem.Therefore, the present invention is the technology that will be provided at the face swing of the part of having used floppy disk and ability of posture control to hold concurrently to lower floppy disk in the record regenerator of optics revision board.

With reference to the accompanying drawings, describe in detail and be the record regenerator of implementing thin compact disc of the present invention, the best example of record regeneration method.
Fig. 1-a to Fig. 1-d, Fig. 2-a to Fig. 2-d, Fig. 3-a is the figure of configuration example of the rotating mechanism part of the summary record regenerator of representing thin compact disc to Fig. 3-d, Fig. 4 to Fig. 6.Rotating mechanism shown in the above-mentioned figure comprises diskette 1 01, ability of posture control plate 102, clip 103, turntable 104.Diskette 1 01 and ability of posture control plate 102 and partition 105 are held between clip 103 and turntable 104, by the rotation driven in rotation of turntable 104.
In it, Fig. 1-a is illustrated on the ability of posture control plate 102 state that has the blow vent of perforation near the excircle of position the position that is provided with of the partition 105 prepared in addition to Fig. 1-d.Fig. 1-a represents from following arranged in order (turntable)-(ability of posture control plate)-(partition)-(floppy disk)-(clip), Fig. 1-b represents from following arranged in order (turntable)-(floppy disk)-(partition)-(ability of posture control plate)-(clip), Fig. 1-c represents that from following arranged in order (clip)-(floppy disk)-(partition)-(ability of posture control plate)-(turntable), Fig. 1-d represents from following arranged in order (clip)-(ability of posture control plate)-(partition)-(floppy disk)-(turntable).By such configuration partition 105,, also can between the slit of partition 105, enter air even partition 105 is pressed onto under the state on the diskette 1 01.Have again, when disc spins, between diskette 1 01 and ability of posture control plate 102, from flowing of inner circumferential edge circumferential edges generation outward air.Can effectively remove face swing thus by the part of generation of static electricity.In addition, the diameter of above-mentioned through hole, number etc. are got the degree of the intensity of not damaging ability of posture control plate 102, but preferably are provided with a plurality of with rotation center symmetry circle-shaped.
Then, Fig. 2-a be illustrated in to Fig. 2-d integrally formed protuberance be set on the ability of posture control plate 102, with it as partition and then near the excircle of the convex position of above-mentioned partition, have the state of the blow vent of perforation.Fig. 2-a represents from following arranged in order (turntable)-(ability of posture control plate)-(partition)-(floppy disk)-(clip), Fig. 2-b represents from following arranged in order (turntable)-(floppy disk)-(partition)-(ability of posture control plate)-(clip), Fig. 2-c represents that from following arranged in order (clip)-(floppy disk)-(partition)-(ability of posture control plate)-(turntable), Fig. 2-d represents from following arranged in order (clip)-(ability of posture control plate)-(partition)-(floppy disk)-(turntable).With above-mentioned identical, when disc spins, between diskette 1 01 and ability of posture control plate 102, from flowing of inner circumferential edge circumferential edges generation outward air.Can effectively remove face swing thus by the part of generation of static electricity.
Then, Fig. 3-a represents to Fig. 3-d, prepares to be provided with the anchor clamps of protuberance and through hole, and it as partition 105, is had the state of the blow vent of perforation near the excircle of the convex position of above-mentioned partition.Bonding partition 105 on ability of posture control plate 102.And then Fig. 3-a represents from following arranged in order (turntable)-(ability of posture control plate)-(partition)-(floppy disk)-(clip), Fig. 3-b represents from following arranged in order (turntable)-(floppy disk)-(partition)-(ability of posture control plate)-(clip), Fig. 3-c represents that from following arranged in order (clip)-(floppy disk)-(partition)-(ability of posture control plate)-(turntable), Fig. 3-d represents from following arranged in order (clip)-(ability of posture control plate)-(partition)-(floppy disk)-(turntable).With above-mentioned identical, when disc spins, between diskette 1 01 and ability of posture control plate 102, from flowing of inner circumferential edge circumferential edges generation outward air.Can effectively remove face swing thus by the part of generation of static electricity.
Fig. 4, except the structure shown in Fig. 1 a, also the upside at diskette 1 01 disposes ability of posture control plate 102.In the face of on the face of diskette 1 01, configuration is along the partition 105 of inner periphery edge at ability of posture control plate 102.When disc spins, diskette 1 01 and between the ability of posture control version 102 of two sides up and down of this floppy disk configuration separately in flowing from inner circumferential edge circumferential edges generation outward air.Thus, can effectively remove face swing by the part of generation of static electricity.Have again, in this structure,, can more effectively stablize the posture of diskette 1 01 thus because the almost equal negative pressure that caused by airflow takes place in the both sides of diskette 1 01.For example, if the part of diskette 1 01 is sagging,, the power effect that lift sagging part is arranged downwards then because bigger negative pressure takes place at an upper portion thereof.It is big more that piece effect is more rotated in this effect.In addition, partition can obtain with aforesaid and the ability of posture control plate is integrally formed or have the same effect of form of protuberance and through hole.
Fig. 5 represents to dispose a plurality of fan-shaped partitions 105 along the inner periphery of ability of posture control plate 102.In addition, on clip 103, through hole is set.Can near the turning axle that coils, guarantee the inflow entrance of air thus, so can expect the effect of high stable posture.
Fig. 6 is the structure that has made up Fig. 4 and method shown in Figure 5.
In addition, at above-mentioned Fig. 1-a to Fig. 1-d, Fig. 2-a to Fig. 2-d, in the configuration example of Fig. 3-a to Fig. 3-d, Fig. 4 to Fig. 6, by in the ability of posture control plate 102 at least one and also at least information area make transparently in advance, so also can make it have the record regenerating function of carrying out the optics correction with laser for the irradiation thin compact disc.For example, when the thick floppy disk of 100 μ m of DVD pit pattern has been duplicated in regeneration,, then can use the optical system record regenerating thin compact disc of existing DVD etc. if the thick glass plate of 500 μ m is used as the ability of posture control plate.In addition, in Fig. 4 and structure shown in Figure 6, if as above-mentioned two sides up and down that make at ability of posture control plate 102 all have the optics debugging functions, then can use the floppy disk of double-sided recording modes form.
[embodiment]
Will thickness be on the polycarbonate film of 100 μ m lamination the pigment recording layer, with silver be major component metallic reflector, protective finish can record regenerating diskette 1 01 external diameter make the annular slab that φ 120mm, internal diameter make φ 15mm.
Abide by above-mentioned example, make the rotating mechanism part of thin compact disc record regenerator, carried out to estimating the various experiments of its performance.The gas cut that produces when using floppy disk is observed for swinging as face, as long as the generation of the focus error signal in the inspection record regenerating unit.
At first, in the existing recorded regenerating unit, the CD and the floppy disk of the thick substrate of 1.2mm have been used in regeneration, have observed the situation occurred of the focus error signal in the occasion separately.Its result is illustrated respectively among Fig. 7 and Fig. 8.From these figure as can be known, using the occasion of floppy disk, than the occasion of the thick CD of uses 1.2mm, focus error signal greatly takes place, so a large amount of gas cuts has taken place in judgement.
Then, observed the situation occurred of the focus error signal in the thin compact disc record regenerator of abideing by above-mentioned example making.As shown in Figure 9, as can be known: abide by the thin compact disc record regenerator that above-mentioned example is made, can significantly suppress the generation of focus error signal than the regenerating unit of it existing floppy disk.That is, in the thin compact disc record regenerator of this example, by making it flowing of air taken place between floppy disk and ability of posture control plate, can lower gas cut and take place, simultaneously, even the occasion that takes place at gas cut also can effectively be eliminated it.
Then, prepare the ability of posture control plate of external diameter φ 120mm and φ 125mm, and to observing separately.It the results are shown in Figure 10.From this figure as can be known, bigger slightly as if the external diameter of ability of posture control plate is made than the external diameter of floppy disk, can access bigger stable posture effect.Can envision,, then follow the rotation of floppy disk and ability of posture control plate, the turbulent flow of air has taken place if note the floppy disk outer circumference portion.Therefore, can think that it is the face oscillating quantity increase of floppy disk as a result because non-constant power takes place the turbulent flow of this air on floppy disk.Can think: the external diameter at the ability of posture control plate is the occasion of φ 120mm, than outside the footpath be the occasion of φ 125mm, suffer stronger turbulence effect, and that face is swung quantitative change is big.
Then, in the two sides sputter of ability of posture control plate 102 that obtains like this and diskette 1 01 the thick SiN film of 3nm.(calling ability of posture control plate A's) this ability of posture control plate 102 is fixed with partition 105, diskette 1 01 as shown in Figure 1a.With 4000rpm rotation player, measured the maximal value of focus error signal, maximal value is 440mV.On the other hand, use and the same plate (being called ability of posture control plate B) of above-mentioned ability of posture control plate except that the formation of having omitted the SiN film, measured the maximal value of focus error signal equally, maximal value is 550mV.Therefore, as can be known: can be obtained big stable posture effect by what same composition formed by overlay film by on ability of posture control plate and thin compact disc facing surfaces, forming.Can think, on ability of posture control plate A, can make the surface of the subtend separately of floppy disk and ability of posture control plate become the electriferous state of same-sign and make it that static reacting force take place mutually, so both can not adsorb, relative therewith, ability of posture control plate B is because static is unsettled former thereby make focus error signal become big.
More than to the record regenerator of thin compact disc of the present invention, represent and concrete example be described, but the invention is not restricted to this.So long as the insider, in the scope that does not break away from aim of the present invention, just can be to the structure and the function various changes and the improvement in addition of the invention of above-mentioned each example or other examples.
