Abstract
A DVDR optical disc structure is prepared for forming reflection layer by the first and the second as well as the third reflection layers, using gold layer as the first reflection layer and silver layer as the second reflection layer as well as copper layer as the third reflection layer.
Description
Technical field
The present invention relates to a kind of compact disk structure, especially the structure of optical data carrier such as DVDR CD (DVD-ROM, DVD9, DVD-R/RW, DVD+R/RW and other DVD form).
Background technology
DVD (Data Versatile Disc) CD because have that storage density height, volume are little, advantage such as storage period limit for length, height with low cost, compatible and error rate are low, having become the main flow of present optical information recording medium, is one of most popular optical storage media.Technically, DVD is newer generation CD storage technique.It is more much bigger on numerical capacity than CD, and read or write speed is faster, can hold the video than the better film class of CD audio frequency, picture and computer data.DVD is intended to cover home entertaining, computer and commercial information with a kind of single digital format.It has been substituted laser disc, is expected to replace video-tape and video-game TV, and might finally replace audio CD and CD-ROM.DVD has obtained from all electronic enterprises and computer hardware enterprise, and the support of film and music studio, and DVD has become the most successful storage medium on the CD storage technique history.
Along with popularizing of multimedia (Multimedia) technology, blank DVD, the application that is also referred to as DVDR is also more and more widely.Data and data such as phonotape and videotape that the user uses DVDR to preserve oneself have become a kind of custom and have selected.DVDR has one deck storage medium in the structure of blank DVD exactly, and the data loggings such as data tones picture that the method that can write by laser is thought that the user preserve when needs read, come reading of data by laser equally in storage medium layer.DVDR provides a kind of cheapness reliable data on file mode for the user, with other the paper medium, the comparing of magnetic medium with storage mediums such as semiconductors, have great advantage.Because cheap, the holding time is long, be highly suitable for small-scale data distribution and personalized collection.The output of blank DVDR is occupied increasing share above the DVD of traditional precompressed content on optical storage market in the world now.
As shown in Figure 1, DVDR CD of the prior art is divided into six layers from top to bottom by physical arrangement: printed layers 6, second substrate layer 5, bonding coat 4, reflection horizon 3, dye coating 2 and first substrate layer 1, described printed layers 6, second substrate layer 5, bonding coat 4, reflection horizon 3, dye coating 2 and first substrate layer 1 stack together from top to bottom in order, form a complete DVDR CD.
Wherein, ground floor is a printed layers 6, is used for printing and relevant information such as customer ID, capacity.
Promptly second substrate layer 5 is the thickest for the second layer, is generally made by PC (polycarbonate) plastics.It occupies volumes maximum in the whole disc, is the key that forms disc strength and shape.
The 3rd layer is bonding coat 4, is used for protecting reflection horizon and dye coating in the CD, and anti-stop signal is destroyed.Be used for bonding second substrate layer and two discs of first substrate layer simultaneously.Its material is generally light-cured acrylic class material, comprising the gummed part.
The 4th layer is reflection horizon 3, is used for reflecting the laser beam of CD-ROM drive or CD writer, reads data in the discs by the laser light reflected light beam.Its material is that purity is 99.99% fine silver metal.
From the structure that constitutes CD we as can be seen, the manufacture process of DVDR disc is in the prior art: at first produce first substrate layer; On first substrate layer, be coated with organic dye then, thereby form dye coating (recording layer); And then on dye coating, the mode by vacuum splashing and plating is added in argent on the dye coating, thereby forms the reflection horizon; And then on the reflection horizon, apply bonding coat; Be bonded together with second substrate layer afterwards; Make printed layers at last, finally finish the manufacturing of CD.Sum up, the manufacture process of DVDR disc comprises that mainly injection moulding substrate, dye-coating, vacuum splashing and plating, bonding, superficial layer print this five steps.
In five steps that disc is made, vacuum splashing and plating is a very part and parcel, it is by sputter layer of metal film on dye coating, is used for reflecting the laser beam of CD-ROM drive or CD writer, thereby reads data in the discs by the laser light reflected light beam.So want to read well the data in the discs, this metallic film must have high reflectivity, otherwise reflector laser may be too faint and can't be identified.Used metal material is essentially fine silver or silver alloy at present.Because the used laser radiation wavelength of DVDR disc is 650nm, and silver is the highest at this wavelength reflectivity, reaches 98.8%.By contrast, the reflectivity of gold is 95.5%, copper be 96.6%, and aluminium is 90.5%.Used silver has the high advantage of reflectivity, relatively is suitable as reflecting material.
Yet in the production run of DVDR disc, though the aridity of the dyestuff of employed dye coating is had very high requirement, it is impossible reaching absolute drying, and the solvent that more or less can contain part in the dyestuff inside.When sputter reflecting material on dye coating, because the chemical property of silver is more active, a small amount of solvent residual easily and in the dye coating reacts, and can cause like this and contain bubble, pin hole etc. in the disc of producing, thereby influence the quality of disc.Will cause the off quality or degradation processing of disc like this, increase optical disc production merchant's manufacturing cost, this obviously is disadvantageous concerning the production of CD.
Simultaneously, the bonding agent glue in the bonding coat also might produce chemical corrosion to argentum reflecting layer, and bonding agent self also can take place corrodes, thereby produces bubble in disc, and the air in the bubble can produce oxidation to silver, will form pin hole behind the certain hour.The CD that contains bubble can will influence the long-term stability in use of DVDR CD like this because the high speed rotating of disc itself produces huge centrifugal force and produces layering when reading of data, even directly causes coiling and scrap and damage fetch equipment.Therefore, seem and imperfect as reflecting material with fine silver (purity is 99.99%) in the conventional art, and also there is certain defective in traditional compact disk structure, is the major reason that causes above-mentioned various defectives.For improving the quality of CD, need improve reflecting material and compact disk structure.

Embodiment
Fig. 1 is the sectional view of the structure of DVDR CD of the prior art, and in this DVDR CD, it comprises single reflection horizon 3, serves as reasons and be formed on the film of the ag material on the dye coating 2 by the vacuum splashing and plating mode in this reflection horizon 3.
Fig. 2 is the sectional view of the DVDR disc structure of first embodiment of the invention.First embodiment of the invention, it comprises two reflection horizon, i.e. the first reflection horizon 3a and the second reflection horizon 3b, preferably, the first reflection horizon 3a is the film of gold copper-base alloy, can be referred to as the gold layer, the second reflection horizon 3b is the film of ag material, can be referred to as silver layer.
Wherein, dye coating 2 is formed on first substrate layer 1.The first reflection horizon 3a (gold layer) is by being formed on this dye coating 2 such as the vacuum splashing and plating mode.The thickness of this first reflection horizon 3a is between about 10-30nm.And this first reflection horizon 3a will cover dye coating 2 fully, and like this, the internal diameter of the first reflection horizon 3a is less than the internal diameter of dye coating 2, and its external diameter is greater than the external diameter of dye coating 2, and promptly the area of the first reflection horizon 3a is greater than the area of dye coating 2.
The second reflection horizon 3b (silver layer) is by being formed on such as the vacuum splashing and plating mode on the first reflection horizon 3a, and thickness can be decided according to the actual requirements between about 50-80nm.The internal diameter of the second reflection horizon 3b is greater than the internal diameter of the first reflection horizon 3a, but internal diameter less than dye coating 2, its external diameter is less than the external diameter of the first reflection horizon 3a, but external diameter greater than dye coating 2, promptly the area of the second reflection horizon 3b is between the first reflection horizon 3a and dye coating 2, greater than dye coating 2 but less than the first reflection horizon 3a;
In first embodiment of the present invention mode, the production technology of DVDR CD roughly is such:
1), spin coating dye coating 2 on first substrate layer 1;
2), on dye coating 2, plate the certain thickness first reflection horizon 3a earlier, thickness is in the scope of about 10-30nm, to cover dye coating 2 fully, promptly the internal diameter of the first reflection horizon 3a is less than the internal diameter of dye coating 2, external diameter that is to say that greater than the external diameter of dye coating 2 area of the first reflection horizon 3a is greater than the area of dye coating 2;
3), on the first reflection horizon 3a, the sputter last layer second reflection horizon 3b again, such as the argentum reflecting layer 3 of routine, thickness can be decided according to the actual requirements in the scope of about 50-80nm.The area of the second reflection horizon 3b is between the first reflection horizon 3a and dye coating 2, greater than dye coating 2 but less than the first reflection horizon 3a;
4), be bonded together, form complete DVDR CD by the bonding coat and second substrate layer 5.
Like this, in the DVDR CD in first embodiment of the present invention, the second reflection horizon 3b (silver layer) is spaced apart fully with dye coating 2 by the first reflection horizon 3a (gold layer), and in actual production, because the sputter first reflection horizon 3a (gold layer) at first, therefore also make the second reflection horizon 3b (silver layer) can not contact with the first reflection horizon 3a (gold layer), therefore just can prevent fully that the second reflection horizon 3b (silver layer) from directly contacting with dye coating 2, so just avoided owing to silver-colored and dye solvent generation chemical reaction produce bubble, the defective of the layering in pin hole and the use has solved the problem that the disc quality descends.
Simultaneously, the reading face from the DVDR CD from CD is seen over, can only see the first reflection horizon 3a (gold layer), so outward appearance seems similar gold dish, and is very attractive in appearance.
In addition, cause corrosion owing to the bonding agent glue in the bonding coat 4 also might produce chemical reaction with argentum reflecting layer, and self also can take place and corrode in bonding agent, thereby in disc, produce bubble, air in the bubble can produce oxidation with silver again, will form pin hole behind the certain hour like this.Further, the huge centrifugal force that the CD that contains bonding bubble can produce because of high speed rotating in use and produce layering can influence the long-time stability of DVDR CD, even directly causes disc to be scrapped and damage fetch equipment.Therefore, in order to overcome this defective, the present invention proposes second kind of embodiment.
Referring to Fig. 3, it shows the sectional view of the DVDR disc structure of second embodiment of the present invention.In second embodiment of the present invention, its basic structure is identical with first embodiment shown in manufacturing process and Fig. 2, and therefore identical structure and manufacturing process are omitted and described.
The DVDR in this second embodiment and the difference of first embodiment are, its reflection horizon is a three-decker, promptly comprise the first reflection horizon 3a, the second reflection horizon 3b and the 3rd reflection horizon 3c, preferably, the first reflection horizon 3a is the film of gold copper-base alloy, can be referred to as the gold layer, the second reflection horizon 3b is the film of ag material, can be referred to as silver layer, the 3rd reflection horizon 3c is the film of copper product, can be referred to as the copper layer.
In the reflection horizon of this three-decker, the same in the structure of the first reflection horizon 3a and the second reflection horizon 3b and second embodiment, the 3rd reflection horizon 3c is by being formed on such as the vacuum splashing and plating mode on the second reflection horizon 3b, the area of the 3rd reflection horizon 3c is greater than the second reflection horizon 3b, and is identical with the first reflection horizon 3a.
In manufacture process, behind the intact first reflection horizon 3a, the second reflection horizon 3b of sputter respectively, sputter the 3rd reflection horizon 3c again on the second reflection horizon 3b, the thickness of the 3rd reflection horizon 3c can depend on actual need and decide.The thickness in first, second and the 3rd reflection horizon can be decided according to concrete needs, and preferably, the gross thickness in first reflection horizon, second reflection horizon and the 3rd reflection horizon is 80nm-120nm.
Smear bonding coat again on the 3rd reflection horizon 3c, be bonded together with another one second substrate layer 5 then, the last printed layers 6 that comprises contents such as DVDR name of product of printing on second substrate layer forms a complete DVDR CD.
Because the 3rd reflection horizon 3c (copper layer) can not react with the glue in the bonding coat 4, the chemical corrosion that so just can prevent the second reflection horizon 3b (silver layer) glue direct and in the bonding coat 4 from contacting and cause, thereby overcome above-mentioned defective effectively, improve the structure of CD, improved the quality of CD.
The DVDR CD of Xing Chenging is seen over from the two sides of CD like this, and what see is first reflection horizon (gold layer) and the 3rd reflection horizon (copper layer), seems that from the outward appearance on two sides all similar gold coils.
With reference now to Fig. 4,, it shows the 3rd embodiment of the present invention.In the above-described 2nd embodiment, bonding coat 4 directly contacts with second substrate layer 5, and like this, the glue in the bonding coat can react with the makrolon material of second substrate layer 5, thereby the quality of CD is produced adverse influence.Directly contact with second substrate layer 5 for fear of bonding coat 4, the 3rd embodiment of the present invention has adopted a kind of novel disc structure.
In the 3rd embodiment, different with second embodiment is, the 3rd reflection horizon 3c (copper layer) is not formed on the second reflection horizon 3b, but such as being formed on second substrate layer 5 by the vacuum splashing and plating mode.Then, will be formed with second substrate layer 5 of the 3rd reflection horizon 3c and be formed with first, second reflection horizon 3a by the bonding coat 4 that is arranged on the second reflection horizon 3b, first substrate layer 1 of 3b is bonded together, thereby forms complete DVDR CD.Such second substrate layer 5 is spaced apart fully by the 3rd reflection horizon 3c and bonding coat 4, has avoided owing to directly contact the problem that is produced.
The area of the 3rd reflection horizon 3c is greater than the second reflection horizon 3b, and is identical with the first reflection horizon 3a.The thickness in first, second and the 3rd reflection horizon can be decided according to concrete needs, and preferably, the gross thickness in first reflection horizon, second reflection horizon and the 3rd reflection horizon is 80nm-120nm.
Should be realized that, description to the structure of the DVDR CD in the 3rd embodiment only relates to and the different place of aforementioned first, second embodiment above, and its something in common has been omitted such as the description of configuration aspects such as first, second reflection horizon and manufacturing process aspect etc.
The 3rd enforcement embodiment and second embodiment can reach the effect of protection dye coating equally; but also the makrolon material of bonding coat and first substrate layer and second substrate layer can be kept apart, make CD defective occur thereby avoid producing chemical reaction.
The 3rd by way of example and second embodiment have similar effects really in appearance, and promptly the outward appearance from the two sides seems similar gold dish, and easier realization on technology.
More than the present invention has been done exemplary description, what should be understood that is, under the situation of the scope that does not break away from the protection of spirit of the present invention and appended claims, any modification, revises or is equal to replacement and all fall within protection scope of the present invention.
