Description of the invention (1) [Field of invention] (Please read the precautions on the back before filling out this page) The present invention is about a manufacturing device for optical storage media. More specifically, it is about the dielectric layer A manufacturing apparatus for laminating a film to produce a re-burnable optical storage medium. In particular, the present invention relates to an apparatus for manufacturing an optical storage medium, which can improve the manufacturing yield of optical storage media and reduce operating costs. [Related technical descriptions] CD-R, CD-RW, DVD-R, DVD-RW, etc. are currently widely used in music or information fields for playback-only, re-burning, and re-burning optical discs. The medium is to add an optical recording layer and a photoelectric magnetic recording layer on a transparent substrate such as glass or plastic to achieve the function of an optical storage medium. The optical and opto-magnetic information CD (Compact D1Sc), which has been rapidly spread in recent years, has two types: an additional recording type and a re-recording type. The CD-R is an optical information medium that can only be burned once. If it fails to burn once, it cannot be used because it cannot be corrected and must be discarded. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. To improve the above-mentioned shortcomings, the rewritable optical disc system appears to be well-known, including a photoelectric magnetic disc system, a phase change optical disc system, and an organic pigment optical disc system. Each of these optical disc systems has advantages and disadvantages. For example, CD-RW using electro-optical magnetic discs has disadvantages such as difficulty in overwriting and poor interchangeability with CD-ROM and CD-R. Therefore, the practical development of phase-change re-recording CD-RW discs that are relatively interchangeable in principle is very important. This paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) -4- 505920 A7 B7 V. Description of the invention (2) (Please read the precautions on the back before filling this page) Phase change disc When a recording film is formed by a sputtering method, the film is amorphous and has a low reflectance. If the film in this state is subjected to lower temperature heating-slow cooling, the portion will crystallize and exhibit a higher reflectance than that in the amorphous state. If this part is rapidly heated by laser light to the vicinity of the melting temperature of the recording film and rapidly cooled, it will not be crystallized, and will return to an amorphous state to form a hole (Pit). To eliminate it, use a laser pulse to heat it slowly, cool it down, and recrystallize it. Generally, the laser used in the phase-change optical disc system during burning and reading and the laser used for erasing are independent semiconductor lasers with different wavelengths. The recording, playback, and deletion are achieved by irradiation of a laser beam. Functional optical memory media utilize state transitions between crystalline-amorphous and crystalline-crystalline phases. Since this phase change type recording medium can use a single light beam to achieve the overwrite function (especially the photoelectric magnetic memory is difficult in this respect), a simpler optical system can be used in the recorder. Recently, research and development in practical applications have made considerable progress. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs, most of the above CD-R and other phase-change optical storage media are multilayered structures with dielectric layers sandwiched between the upper and lower sides of the recording layer. Generally, if these optical storage media are manufactured by using a plastic film such as a polycarbonate (polycarbonate) substrate or a glass substrate coated with plastic to make various layers into a thin film by a lamination method, the splash will occur. The coating method (hereinafter referred to as sputtering) is indispensable. Regarding the spray coating method, the inline method and the leaf-type spray coating device are used. -S ** This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 505920 A7 B7 V. Description of the invention (3 ) (Please read the notes on the back before filling this page). The former inline method has better productivity because it can be spray-coated on both sides, but the latter is the mainstream in recent years. Compared with the former, although the productivity is slightly worse, the installation area of the device only needs to be less than half, and the substrate can be directly transported without the need for a tray, and the film quality is easier to maintain. Because of its advantages such as high throughput, compactness, and low production costs, it has become the mainstream of manufacturing equipment. Regarding the yield of the above-mentioned optical storage medium, since different materials such as a recording layer, a reflective layer, and a dielectric layer (or a protective layer) must be laminated into a multilayer film on a substrate, there is a defect in the film formation process. If it does, it will cause poor quality and reduce the yield. In the film formation process, especially when the dielectric is formed by a spraying method, the yield rate is often caused by the peeling of the film-forming members attached to the inner periphery of the vacuum chamber on a non-target substrate, etc. decline. Therefore, in order to improve the yield and reduce the operating cost of the manufacturing equipment, how to try to prevent the film-forming materials that grow on the substrate and other parts from peeling off and fall off for a long time to make the manufacturing equipment run smoothly becomes a very important factor. . Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs for this purpose, the general practice is to install a guard plate to prevent the inner surface of the vacuum tank from being attached, and at the same time, replace the guard plate to prevent attachments from falling. Fall on the substrate. However, every time the attachment plate is replaced, the vacuum system must be released and returned to the atmosphere to perform the replacement work. This approach increases the down time of the device and increases the operating cost, which cannot fully meet the needs. In addition, in the operation of the device, except for the replacement of the anti-plate, it is just applicable to the Chinese paper standard (CNS) A4 specification (210 X 297 mm) -6- 505920 A7 ---_____ B7 V. Description of the invention (4) (Please read the precautions on the back before filling in this page) Except for the special case where the replacement timing of the plated target material is consistent, generally, in the case of dielectric film formation, the replacement cycle of the target material is far. Much longer than the replacement cycle of the attachment plate. Therefore, if it is necessary to replace the anti-plate at the time of replacement of the plating target material, it is not possible to sufficiently prevent the drop of the yield caused by the adherence of the anti-plate from falling off. In order to improve this problem, it is common to apply a blast treatment to the blocking plate, and increase the surface area to improve the adhesion so that peeling of the adhesion film can be suppressed. However, at present, it is impossible to improve the yield rate and the operating rate of the device. Explanation: Therefore, the object of the present invention is to improve an optical storage medium manufacturing device, to solve all the problems existing in the above-mentioned inherent technology, to improve the yield of optical storage media such as CD-RW in the manufacturing process, and to improve the operation of the device. Rate to reduce operating costs. As described above, in the process of laminating a reflective layer, a recording layer, a protective layer, a dielectric layer, and the like into a thin film on a substrate by using a thermal spraying device (especially a leaf spraying device that is widely used recently). There are various problems that must be resolved, and in the current situation, they have not been fully resolved. Printed by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs To solve the problems described above, the inventor of the present invention, after reviewing the results of intensive review, focused on the growth and separation of the fall, and invented a solution. That is, the present invention provides a manufacturing apparatus for an optical storage medium in which a reflective layer, a recording layer, and a dielectric layer are laminated and laminated on a disc substrate. It is characterized in that the vacuum film forming tank of the manufacturing device is equipped with plating -7- This paper size is applicable to Chinese National Standard (CNS) A4 (210 X 297 mm) 505920 A7 ——— B7 V. Description of the invention ( 5) Lamellar structure of the metal layer. (Please read the note on the back? Matters before filling out this page.) As mentioned above, the deposits generated during the deposition process due to attachment growth will be affected by the ambient temperature rising and falling during the deposition process. Thermal shock, thermal stress, and even mechanical vibration. If the anti-sticking plate with the coating layer having the metal layered structure described in the present invention is installed in the vacuum tank, these stresses will be mitigated by the layered structure, and the attached growths on the periphery will not easily peel off and fall off. . Compared with the inherent anti-sticking plate, the tendency of foreign matter to be mixed on the substrate is significantly reduced. As a result, the yield of the film formation and the operating rate of the manufacturing apparatus can be significantly improved. DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention applied to an apparatus for manufacturing an optical storage medium will be described in detail. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs The metal coating layer of the present invention for preventing plate surface and the like in a vacuum tank has a layered structure as shown in FIG. 1. The metal suitable for the present invention preferably has a shear modulus of 6 X 1 0 P a or less. In this way, in addition to the above-mentioned layered structure, in addition to its stress relaxation properties due to its structural properties, it is also possible to make the stress relaxation effect of the attached matter better. In the present invention, in addition to the aforementioned limitation of the metal shear modulus of elasticity, the film thickness of the metal layer having a layered structure is preferably more than 10 / im. If the film thickness is less than 1 0 // m, the above-mentioned stress cannot be sufficiently absorbed, and therefore, the relaxation effect cannot be fully exerted. If it can be further used to form the layered structure with the aforementioned film thickness, 2 paper sizes are applicable to the Chinese National Standard (CNS) A4 Regulation (210 X 297 mm) -8- 505920 A7 _— B7 V. Description of the invention ( 6) More than two kinds of metal layers with different elastic coefficients, the present invention will be able to exert its stress relaxation effect more. (Please read the note on the back? Matters before filling out this page) Using a multi-layer structure can avoid the rapid concentration of stress relaxation, and the staged relaxation can reduce the reaction force caused by the adhesion stress relaxation, and it is not easy to occur. Peeling due to breakage. In addition, with regard to the aforementioned stress relaxation, the smaller the coefficient of shear elasticity of the metal, the more effective and rapid it is. Although the present invention is not particularly limited, the magnitude of these shear elasticities and the order in which they are laminated may be appropriately selected as needed. When the present invention forms a layered structure of two or more metals with different shear elastic coefficients as described above, for example, in the order of lamination formation of the base material against the plate, the shear elastic coefficient preferably starts from the mother village. Order reduction is more appropriate. In this case, because the shear elasticity coefficient of the metal layer attached to the uppermost layer is the smallest, the stress occurring on the adherend can be quickly absorbed and eliminated. For the same reason, it is possible to reduce the reaction force caused by the stress relaxation of the adherend, and peeling and falling due to breakage is not easy to occur. If the consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs prints a method of gradually reducing the shear elasticity coefficient from the base material to form a metal with a different shear elasticity coefficient, it can not only disperse the stress of the attached film, but also make the peeling material Recycling becomes easier. At the same time, if metal layered structures with different shear elastic coefficients are formed into multiple layers, the first layer attached to the anti-sticking plate can be formed by using a metal layer with a relatively large shear elastic coefficient. Therefore, when preventing plate exchange, it is easy to use ballast treatment and other methods to peel off the attachments and the paper size applies the Chinese National Standard (CNS) A4 (210 X 297 mm) -9- 505920 A7 ______ B7 V. Description of the invention (7) Recycling and reducing the cost of stripping and recycling. < Please read the precautions on the back before filling this page) As stated above, "The metal layered structure implemented in the present invention is shown in Fig. 1" on the metal surface 1 of the base material of the anti-board, As if the playing cards are stacked and stacked, the scaly metal will be formed into a layered structure 2 as shown in FIG. According to the present invention, when a lamellar layer is formed on a base material, it may be formed according to need. 'It is better to blast the base material into a rough surface beforehand. From the viewpoint of adhesion, it will be more Suitable for. As for the material of the base material, generally, there are stainless steel, aluminum, aluminum alloy, and plastic ', but stainless steel and aluminum alloy are more suitable in terms of workability, stability, and cost. In addition, it is suitable that the elastic coefficient of the metal forming the layered structure is larger than that of the material formed on the substrate. Generally there are aluminum, aluminum alloys, copper, copper alloys, indium, zinc, gold, silver, rhenium, etc. From the perspective of cost, aluminum alloys and copper alloys are more suitable. In the present invention, as described above, one kind may be used or a combination of two or more kinds may be used for the lamination. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs In addition, it would be better if the shear elasticity coefficients of metals with different shear elasticity coefficients are gradually reduced from the base material and arranged. The smaller the elastic modulus of the metal layer with the layered structure, the better, but if it is too small, it will be difficult to peel using the gravel method, etc. It will take more time to recycle and damage the base material. In addition, during recycling, although there is also a method of using an acidic material to peel off, most of the dielectric on the phase change storage medium uses Z n S · S i 0 2 If the acid treatment is performed, hydrogen sulfide will be generated. It is difficult to apply the Chinese national standard (CNS) A4 specification (210 X 297 mm) to this paper size. -10-505920 A7 __.... B7 5. Description of the invention (8) Disposal will also harm the base material. (Please read the precautions on the back before filling out this page.) The method of forming the layered structure is most suitable for spray coating. The thermal spraying method used includes arc method (frac) method, plasma method (plasma method), and the like. From the viewpoint of cost and adhesion, the arc method is most suitable for the following embodiments. Examples further illustrate the present invention.

In this embodiment, both the first layer and the second layer are Z n S · S i 0 2 dielectric layers.

In Comparative Example 3, the surface of the first protective layer and the second protective layer of the leaf-type thermal spraying device is formed into a vacuum blasting chamber by sand blasting to a roughness R. After a = 8 μm anti-plate, make a disc substrate. Using the discs produced in the above examples and comparative examples, a defect rate inspection device made by SONY was used to measure the overall defect rate of the disc substrate at a rate of 3 pieces every 30 minutes, and the average of the defect rates of the 3 pieces was determined. The results of the comparison are shown in Table 1. Each time, the target and the blocking plate of each vacuum tank were replaced with new ones. The initial defect rate was 1 to 2 x 1 0 to 6. The examples and the comparative examples were the same.

Description of the invention (11) (Please read the precautions on the back before filling this page) The stress of the attachment is easily relaxed. Compared with the traditional, the peeling and falling of the attachment will be significantly reduced, so the defects of the disc will be reduced, and the yield rate will be increased. In addition, since the shear elastic coefficient of the metal layer forming the layered structure is set to 6 X 1 0 1 P a or less, the effect of stress relaxation can be exhibited more effectively. Similarly, the defects of the disc can be reduced, and the yield rate can be increased. In addition, since the film thickness of the metal layer forming the layered structure is set to 10 # m or more, the layered structure can fully exert the effect of stress relaxation. Similarly, the defects of the disc can be reduced, and the yield rate can be increased. In addition, because two or more metal layers with different shear elastic coefficients are used to form this layered structure, the stress is gradually concentrated on the metal layer with the smallest shear elastic coefficient, so it will be relaxed and no sharp reaction will occur. Force, the effect will be better. In the same way, it can reduce the defect of the disc and increase the yield rate. It is printed by the consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs and when two or more metal layered structures with different shear elastic coefficients are formed, the shear elasticity is determined. The magnitude of the rate gradually decreases from the anti-plate of the base material, that is, the shear elasticity coefficient of the uppermost layer is the smallest, so the effect of stress relaxation of the attached matter can be effectively exerted. In the same way, the defects of the disc can be reduced, and the yield rate can be increased. At the same time, since a metal layer with a large shear elastic coefficient is coated on the base material of the anti-sticking plate, it can be easily peeled by sandblasting or the like to reduce the cost of peeling and recycling. Brief description of the round form Figure 1 shows the size of the paper sheet of the metal layer with a layered structure applied on the anti-plate.
