Description
Invention field
The present invention relates to a kind of label that is used for CD or light disk packing, relate in particular to a kind of method and apparatus of the visible indication that is used to provide relevant with the degenerate state of CD.
Background technology
Nowadays, optical disc is extensively used as data storage medium.Utilize CD as a major defect of data storage medium to be: be uncertain the serviceable life of CD.
The CD that has three kinds of fundamental types, promptly CD, DVD and BD (blue light) coil, and every type comprises ROM, R and RW form again.In these disc-types each has all been utilized different data layer material (for example being respectively molded aluminium, silver mirror, organic dyestuff or phase-change film).Suppose that in use the physical treatment to dish is correct, cause disk degeneration so, and finally to cause the main cause of " end-of-life " of coiling be exactly the deterioration of these materials.
When using CD and DVD, the user can not notice degeneration in early days, because build the mistake that error-detecting in the system and calibration capability can be proofreaied and correct some in by interior.Have only when error recovery coding fully during error recovery, the user just can notice and go wrong.
A kind ofly be used for determining that the method for the end-of-life of dish is: the quantity of the mistake before taking place according to error recovery on dish is determined the end-of-life of coiling.The chance that dish breaks down increases with the quantity of mistake, but limit for the number of errors that in dish, will cause performance issue (slight or serious) for certain, then be impossible, because the quantity that this depends on the mistake of leaving over after the error recovery also depends on its distribution in data.When the number of errors (before error recovery) on the dish increased to a certain degree, the chance (even very little) that dish breaks down can be considered to unacceptable, and had therefore shown the end-of-life of this dish.
The life-span of ROM dish is determined by the degree that the aluminium lamination that coils is exposed to oxygen.Oxygen (comprising pollutant) enters by moisture, and can move through layer of polycarbonate or hard varnish layer (CD label side and edge).Oxygen or moisture are more easy through the zone of cut, crack or leafing in the label.Oxygen also may be stayed in manufacture process in the dish.
If dish is placed in the very moist environment, moisture and oxygen finally can arrive aluminium so, cause its loss reflectivity.This is that reflectivity descends a lot because the aluminium of normally polishing (similar to silver) can become the oxide of passivation.The combination of the temperature of high humility and rising will be accelerated oxidation rate.
Therefore, its long-time environmental baseline that exposes is depended in the mean lifetime of ROM dish.Usually, preferably the ROM dish is kept in the environment of drying, low temperature.
For not coiling (R dish) by " one-time write " that CD or DVD driver are wiped, minute surface is made of silver under the normal condition.Silver is being exposed to corrosion-vulnerable under the condition of sulphuric dioxide, and sulphuric dioxide is air pollutants, and it can see through dish with moisture in the mode identical with oxygen.Similarly, when being exposed to oxygen or moisture, silver also can corrode.
The R dish will be used for record data based on the layer (organic dyestuff) of dyestuff.The organic dyestuff that in the data Layer of R dish, uses along with the time naturally but degenerate lentamente.High temperature and high humility will speed up this process.Long term exposure can make dye property degenerate in ultraviolet light, and data can not be read.Also will speed up dye degradation by daylight or the heat that causes, in dish, accumulate very much near heated light sources.
Manufacturer claims that CD-R and DVD-R dish had the shelf life in 5 to 10 years before record, but does not indicate expiration date on CD-R, DVD-R or DVD+R packing, does not announce that also test report confirms these statements.
About rewritable disk, generally do not consider these for long-term or filing use, and seldom average durability test for such medium such as RW and ram disc.Rewritable disk is used for record data with the phase-change metal alloy film, and aluminium or silver are used for the reflection horizon.Stable the dyestuff that alloy film uses in the R dish, because this material is under normal circumstances degenerated with fast speeds.In the RW dish, also find the silver of reflection or the degeneration of aluminium lamination easily.
In ageing process, the influence that phase-change film mainly is heated still also is subjected to the influence of ultraviolet light (UV).The combination of high temperature and ultraviolet light can further accelerated deterioration process.
Data on phase-change metal alloy rete can be wiped and rewrite by limited number of time ground (for the RW dish approximately is 1000 times, approximately is 100000 times for ram disc).But this rewriting has influenced the mean lifetime of dish really.In other words, RW that files after record for the first time or ram disc should have longer mean lifetime than living through several wiping-write down those dishes of round-robin.Having only under the situation of normal deterioration velocity, the mean lifetime of RW and ram disc will be shorter than the mean lifetime of R dish.Increase repeatedly and rewrite, mean lifetime even can be shorter.
Dish manufacturer offers some clarification on the expected service life of CD sometimes.Yet problem is to be very difficult to prediction the serviceable life of dish and to depend on many external factors, as the operation and the environmental baseline of dish.And, the not standard method in the serviceable life of prediction dish at present.
Manufacturer comes dish is tested by utilizing quick aging method, and described quick aging method has controlled ultimate temperature and humidity effect in relatively short a period of time.After the same method, test is exposed to the CD of ultraviolet light.But, may not always know how manufacturer explains its measurement result so that determine the end-of-life of dish.Have only minority (if any) independently to announce in the laboratory about the mean lifetime report quilt of these dishes.For CD, expectation value changed between 5 to 100 years.Reduced the user serviceable life of this unknown to CD being used as the confidence of storage medium.
JP 60-239927 discloses a kind of known system, and this system determines the degeneration of dish in playback procedure by monitoring catoptrical signal level, therefore can provide warning to the user, promptly data should be transferred on the new building.But this system has following shortcoming, and promptly warning system depends on actual device from this dish reading of data, and this can coil under the unexpected out-of-work situation at this and cause loss of data.
JP 03-119533 discloses another kind of known system, wherein place indicator near the periphery of dish, and wherein dyestuff fades in time.But this system has following shortcoming, and the true indication of CD degenerate state promptly can not be provided.
Except above mentioned shortcoming, if CD does not use for a long time, for example because only should coil and be used as back-up disk, this CD end-of-life phase that (for example in individual shown in Figure 1 makes an inventory of goods in a warehouse light disk packing 1 in 3) may pass through this CD when storage so.
Summary of the invention
The object of the present invention is to provide a kind of label that is used for CD or light disk packing, its be used for to the user provide CD degenerate state indication and do not have above mentioned shortcoming.
According to the present invention, provide a kind of label that is used for providing the indication of the aging or degenerate state of CD to the user.This label comprises transparent covering layer and is used to provide CD to wear out or the marker of the visible indication of degenerate state.This transparent covering layer and marker are configured to the array configuration effect, thereby make marker be exposed to environmental parameter via transparent covering layer, cause the aging of marker and pairing CD or degenerate to change visual appearance relatively.
The present invention has following advantage, promptly the degenerate state of dish can be sent to the user and do not have the shortcoming that is associated with prior art.
According to another embodiment of the invention, provide a kind of light disk packing, this packing comprises the label as limiting in the claim.
The present invention has following advantage, promptly allows the user to determine the degenerate state of CD and needn't take out CD from light disk packing.
According to another embodiment of the invention, provide a kind of CD that comprises as the label that limits in the claim.
Description of drawings
In order to understand the present invention better and clearly show that how to realize the present invention, only describe with reference to following accompanying drawing by way of example now, in the accompanying drawings:
Fig. 1 shows CD and how to be stored in the storehouse usually;
Fig. 2 has illustrated how to store CD according to the present invention;
Fig. 3 shows the label according to first embodiment of the invention;
Fig. 4 shows the label according to second embodiment of the invention;

Embodiment
Fig. 2 shows the example of the CD server 1 that is used to store light disk packing 3.Each light disk packing 3 all comprises label 5, and this label is used to provide about the degeneration of pairing CD or the visible indication of ageing state.The meaning of " pairing " CD provides the CD of packing 3, perhaps is stored at the CD in the packing 3.
Fig. 3 shows the label according to first embodiment of the invention.Label 5 comprises the marker 101 that is covered by transparent covering layer 103.Tack coat 105 is provided, is used for label 5 is fitted to the dish packing.Restraining barrier 107 is provided, is used for preventing that tack coat 105 is penetrated into marker 101.According to first embodiment, label 5 is covered by strip of paper used for sealing 109, and this strip of paper used for sealing must be removed (for example when being inserted into CD in the packing) by manufacturer, in case perhaps the user has bought this CD just by user's removal (for example for R or RW dish).
It will be understood by those skilled in the art that and various reactive dye and photobleaching agent can be used as marker 101.
For example, marker 101 can comprise the dyestuff that contains leucomethylene blue, and this is based on the known indicator in the redox titration.Therefore, coloring mechanism is according to leucomethylene blue (transparent) is oxidized to methylene blue (blueness).In other words, with this dyestuff as marker 101 will cause these reactive dye when oxidized from the transparent blueness that becomes.
Should be appreciated that must be as indicated layer 101 aging be that this mode of the aging actual measurement of pairing dish is adjusted the transparent covering layer 103 and the marker 101 that form label 5, perhaps be configured with array mode.In other words, marker 101 has when being exposed to similar environmental parameter and the expected life of pairing CD stops changing relatively the character of visual appearance.
Fig. 4 shows the second embodiment of the present invention.As the situation of Fig. 3, label 5 comprises the marker 101 that is covered by clear covering 103.Tack coat 105 is provided, is used for label 5 is fitted to the dish packing.Restraining barrier 107 is provided, is used for preventing that tack coat 105 is penetrated into marker 101.Fitting on the tack coat 105 is protective seam 111, and before fitting to label 5 on the light disk packing, the user can remove this protective seam utilizing tack coat 105.
According to this embodiment, label 5 is as one of light disk packing inside project and adding independently, and covered by the protective package (not shown).For example, this protective package should be opaque, and preferably comprises blanket gas (as N
2).Then, the user can determine when to place label 5 and where label 5 is placed on.In other words, when the user wanted to use indicating label, the user opened sack, peelled off bottom protective layer 111 and also this indicating label was sticked on the needed surface.The consumer also can buy a large amount of label 5 individually.
Preferably, marker 101 can be configured to and can adjust it.For example, reactive dye also can comprise 2 ethyl hexanoic acid tin (II) (Sn (II) 2-ethyl hexonoate), and this makes that adjusting coloring mechanism becomes possibility.In this manner, can control colour switching by another kind of oxidation reaction, described another kind of oxidation reaction relates to and converts 2 ethyl hexanoic acid tin (II) to 2 ethyl hexanoic acid tin (IV).Opposite with the methylene blue redox couple, the latter's conversion is not a balanced reaction.The oxidation potential of 2 ethyl hexanoic acid tin (II) is more much lower than the oxidation potential of leucomethylene blue.Therefore, oxygenant is being arranged (from oxygen, the H of environment
2O etc.) under the situation, all Sn (II) salt is all with at first oxidized and formation Sn (IV).
When all Sn (II) are depleted, the oxidation of leucomethylene blue and painted will the beginning.The concentration of 2 ethyl hexanoic acid tin (II) in dye coating will determine that this dish begins to become ferment the time (the incubation time) before the basket.This time can be controlled by the amount of 2 ethyl hexanoic acid tin (II) in the reactive dye.Therefore, in dye coating, add or deduct 2 ethyl hexanoic acid tin (II) and will increase or reduce label 5 respectively and begin to become blue fermenting the time before.
Being controlled at label 5, to begin to become the another kind of method of the time of fermenting before basket be for example to cover this dyestuff with oxygen diffusion barrier, and described oxygen diffusion barrier is such as silicon nitride (Si
3N
4) or polymkeric substance.There are many possible materials can be used as diffusion spacers.Oxygen is controlled by following equation by the diffusion of this diffusion spacers:
Therefore, adding oxygen diffusion barrier has increased and has been used to make painted the fermenting the time of dish.As finding out from equation (1), by this way can significant prolongation this ferment the time.
It is relevant that the time of fermenting before making the painted beginning of label and leucomethylene blue (transparent) are oxidized to methylene blue (blue).
Preferably, the degeneration in the pairing dish of simulation further can be clipped in marker 101 in the middle of polycarbonate substrate and the emulsion sheet, is similar to pairing dish.
Being controlled at label, to begin to become the another kind of method of the time of fermenting before basket be to adjust the oxygen permeability of transparent covering layer 103 (perhaps polycarbonate substrate or the emulsion sheet in the example that leading portion is described).The oxygen permeability of transparent covering layer 103 or polycarbonate substrate has been determined the oxygen diffusion by this transparent covering layer or polycarbonate substrate.
Above-mentioned proposed indicating device, promptly leucomethylene blue is a kind of useful material standed for, because it follows the tracks of the oxidation of being undertaken by oxygen or water.Oxidation is that serious risk is arranged for the performance of pairing dish, because it will make the specular layer deterioration, has been found that this is one of the problem in main serviceable life in climatic test.But this is not the sole cause that causes degeneration.This label also should monitoring temperature and the reduction of the dish performance that causes of uv-exposure.The ultraviolet sensitivity organic compound of variable color is known for those skilled in the art when exposure.Temperature indicator (TI) also is known, but for the application, preferably measures the watch-dog of a certain accumulated value (heat is exposed to temporal integration).Can be used for this purpose at the organic molecule that begins to resolve into colored fragment such as 50 ℃.
As can be understood from the above embodiments, label 5 provides visible indication about the CD degenerate state to the user.
According to a further aspect in the invention, as the replaceable mode that label is placed on the light disk packing, also this label can be placed on CD originally on one's body.This has following advantage, and the indication of the degenerate state of dish promptly can be provided by structure labelled rather than must change dish itself simply.Should be noted that fitting to relevant described each feature of light disk packing with label also can be applied to this label is fitted to CD itself.
When the CD that label is placed on the cover data layer region is partly gone up, should be appreciated that with this tag configurations to be to make it not hinder the operation of CD.
How the color that Fig. 5 shows label 5 changes in time, and the indication of CD degenerate state is provided thus.At moment T=
0, marker 101 is transparent, indicates pairing dish to be in good state thus.At moment T=T
1, color changes slightly, and indicating pairing dish just becoming thus has degeneration slightly.At moment T=T
2, color obviously changes, and indicates the data of storing on pairing dish to transfer on the new building as quickly as possible thus.By this way, marker 101 is configured to make it that indication of the degree that CD degenerating is provided.
Fig. 6 shows the reversible oxidation-reduction process that leucomethylene blue (transparent) becomes methylene blue (blueness).
The present invention has following advantage, promptly by watching the degeneration that the CD that is positioned at the restoration position place or light disk packing just can monitoring panel simply.
The present invention also has additional advantage, promptly can make a large amount of independent labels simultaneously in force, has reduced the cost of single label thus.
Should be noted that term " variable color " at first comprises from " transparent " state becomes particular color, becomes another kind of color or become another kind of bright-dark degree with a kind of color from a kind of a kind of bright-dark degree of color from a kind of color.
Although the description of the invention of describing in each embodiment relates to the color that changes indicating device 101 in response to environmental baseline, should be appreciated that also can be so that a certain other forms of visual characteristic changes.For example, indicating device 101 can be configured to when indicator changes in time, provide another kind of visual effect,, provide the indication that data should be transferred on the new building to the user thus as " foaming outward appearance " or " crannied outward appearance ".
Should be appreciated that the arbitrary position in the lamination that marker 101 can be placed in the label 5.
In addition, should be noted that, can omit the removable protective seam 111 among the embodiment of Fig. 4 so if in manufacture process, label 5 directly is attached on the packing.Equally, the label 5 of Fig. 3 can have the layer 111 similar protective seam with Fig. 4, so the user can stick the label that has removable strip of paper used for sealing 109.
Should be noted that the foregoing description to illustrate and unrestricted the present invention, those skilled in the art can design many interchangeable embodiment under the situation of the scope that does not deviate from the claim of enclosing.Speech " comprise " do not get rid of also exist with claim in listed element or different element or the steps of step.
