本発明は、スタンパと基板とを液状の樹脂を介して対接
させ、この樹脂を硬化させて基板に接着させることによ
って情報記録媒体を複製する装置に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention makes it possible to reproduce information recording media by bringing a stamper and a substrate into contact with each other via a liquid resin, and by curing the resin and adhering it to the substrate. This relates to a device for
本発明は、上記の様な情報記録媒体の複製装置において
、スタンパに対する基板の心出しを行う軸部材に大径部
と小径部とを設け、更に大径部の一部に突出部を設ける
ことによって、高品質の情報記録媒体を高い生産性で複
製することができる様にしたものである。The present invention provides an information recording medium duplication apparatus as described above, in which a shaft member for centering a substrate with respect to a stamper is provided with a large diameter part and a small diameter part, and further a protruding part is provided in a part of the large diameter part. This makes it possible to copy high-quality information recording media with high productivity.
スタンパを用いて情報記録媒体を複製する方法には、2
P法(光重合法)、コンブレフジョンモールド法、イン
ジェクションモールド法等の各種の方法がある。There are two methods for duplicating an information recording medium using a stamper.
There are various methods such as P method (photopolymerization method), combination mold method, and injection mold method.
しかしその中でも、2P法等の様に液状の樹脂を硬化さ
せる方法は、スタンパのパターンが微細でも樹脂が液状
であるためにこの樹脂がパターンに十分に充填されるの
で、信号の転写性が格段に優れている。However, among these methods, methods such as the 2P method in which liquid resin is cured have significantly improved signal transferability because even if the stamper pattern is minute, the resin is liquid and the pattern is sufficiently filled with the resin. Excellent.
第2図は、上述の様な2P法の原理を示している。この
2P法では、第2A図に示す様にまずスタンバ11上に
紫外線硬化樹脂12を載せ、次に平坦な透明基板13を
スタンパ11へ接近させることによって、第2B図に示
す様にスタンパ11と透明基板13との間に紫外線硬化
樹脂12を充填する。FIG. 2 shows the principle of the 2P method as described above. In this 2P method, as shown in FIG. 2A, an ultraviolet curable resin 12 is first placed on a standber 11, and then a flat transparent substrate 13 is brought close to the stamper 11, and then the stamper 11 is attached as shown in FIG. 2B. An ultraviolet curing resin 12 is filled between the transparent substrate 13 and the transparent substrate 13 .
そして、この状態で透明基板13側から紫外線を照射す
ることによって紫外線硬化樹脂12を硬化させ、その後
、紫外線硬化樹脂12が接着した透明基板13を第2C
図に示す様にスタンパ11から剥離する。この様にして
、信号を転写された情報記録媒体14が複製される。Then, in this state, the ultraviolet curable resin 12 is cured by irradiating ultraviolet rays from the side of the transparent substrate 13, and then the transparent substrate 13 to which the ultraviolet curable resin 12 is bonded is transferred to the second C.
It is peeled off from the stamper 11 as shown in the figure. In this way, the information recording medium 14 onto which the signal has been transferred is duplicated.
ところで、2P法で使用する透明基板13の形状には、
大きく分けて次の二種類がある。そのうちの一つは、最
終製品の形状に予め加工されている基板であり、例えば
コンパクトディスク用では、外径120關、中心孔径1
5龍の円盤である。また他の一つは、信号の転写後に後
加工を行うことを前徒としている基板である。By the way, the shape of the transparent substrate 13 used in the 2P method is as follows:
There are two main types: One of them is a substrate that is pre-processed into the shape of the final product.For example, for compact discs, the outer diameter is 120 mm and the center hole diameter is 1.
It is a disk of five dragons. The other type is a substrate that requires post-processing after signal transfer.
しかし後者の基板を用いる場合には、後加工として切削
等が必要であり、生産性が低い。また切削屑の付着等に
よって、*調製品に損傷が発生することもあり、この複
製製品の品質は必ずしも高くない。However, when using the latter substrate, cutting and the like are required as post-processing, resulting in low productivity. Furthermore, the prepared products may be damaged due to the adhesion of cutting chips, etc., and the quality of these replicated products is not necessarily high.
一方、前者の基板を用いる場合には、後加工を行わない
ので、スタンパに対する基板の心出しが必要である。し
かし従来の複製装置では、この心出しが容易でな(、複
製製品に偏心等が発生する要因となっていた。このため
に従来の複製装置では、予め加工されている基板を実用
的には用いることができなかった。On the other hand, when using the former type of substrate, no post-processing is performed, so it is necessary to center the substrate with respect to the stamper. However, in conventional duplicating machines, this centering is not easy (and causes eccentricity in the duplicated products).For this reason, in conventional duplicating machines, it is difficult to perform this centering easily (this causes eccentricity in the duplicated products). could not be used.
また上述の何れの基板を用いる場合でも、従来の装置で
は、第2C図に示した様に基板13の周辺部を反らせて
基Fi13の剥離を行っていた。従って、この剥離が容
易でなく、生産性向上にも限界があった。In addition, no matter which of the above-mentioned substrates is used, in the conventional apparatus, the base Fi 13 is peeled off by warping the peripheral portion of the substrate 13 as shown in FIG. 2C. Therefore, this peeling is not easy, and there is a limit to productivity improvement.

いる基板34を使用することができる。In the information recording medium duplication apparatus according to the present invention, the shaft member 22
Since the substrate Fi 34 is centered with respect to the stamper 33 by the steps shown in FIG.
また、樹脂12の硬化後に軸部材22の突出部27で基
板34を突き上げる様にしているので、基板34をスタ
ンパ33から容易に剥離することができる。Further, since the substrate 34 is pushed up by the protrusion 27 of the shaft member 22 after the resin 12 is cured, the substrate 34 can be easily peeled off from the stamper 33.
しかも、軸部材22の大径部26のうちの小径部25と

基板34を用いる複製時にその基板34に悪影響を及ぼ
すこともない。Moreover, the stamper 33 and the base +ff 134 are connected to the liquid resin 1 with the end face 26a of the large diameter part 26 of the shaft member 22 at the boundary with the small diameter part 25 brought into close contact with the stamper 33.
2, the resin 12 is prevented from adhering to at least the small diameter portion 25 of the shaft member 22. For this reason, the substrate 34 is smoothly peeled off by pushing up the protrusion 27 of the shaft member 22, and there is no adverse effect on the new substrate 34 during duplication.
以下、本発明の一実施例を第1図を参照しながら説明す

する。In this state, the ultraviolet curing resin 12 is placed on a predetermined part of the stamper 33.
, and then insert the center hole 34a of the transparent substrate 34 into the shaft member 22.
The transparent substrate 34 is fitted onto the large diameter portion 26 of the stamper 33.
By approaching the stamper 33 and the transparent substrate 34, the ultraviolet curing resin 12 is filled between the stamper 33 and the transparent substrate 34 as shown in FIG.

軸部材23の突出部27に当接することはない。そして
、この状態で透明基板34側から紫外線を照射すること
によって、紫外線硬化樹脂12を硬化させる。As described above, the edge of the center hole 34a of the transparent substrate 34 has been subjected to a large chamfering process in advance, so even if the transparent substrate 34 approaches the stamper 33, the transparent substrate 34 will not protrude from the shaft member 23. It does not come into contact with the portion 27. Then, in this state, the ultraviolet curing resin 12 is cured by irradiating ultraviolet rays from the transparent substrate 34 side.

される。When this curing is completed, the cylinder 24 moves the shaft member 22 in the six directions of the arrows, and at the same time, high-pressure air is blown out from the opening 31a via the tube 32, the connector 23, and the hollow passage 31. Then, the ultraviolet curing resin 12 is cured and the adhered transparent substrate 34 is peeled off from the stamper 33 due to the push-up by the protrusion 27 of the shaft member 22 and the high-pressure air.
以上の様な本実施例の複製装置では、突出部27による

ー等が発生しにく い。Further, since the stamper 33 is attracted by the flat electromagnet 21 and is pressed by the end face 26a of the large diameter portion 26 of the shaft member 22, even if the stamper 33 is subjected to stress, the stamper 33 can be placed on a smooth flat surface. It is kept in the same condition. Therefore, the signal from the stamper 33 is transferred to the duplicated product in a positive direction, making it difficult for skew to occur.

、後加工を必要とする場合もある。If the ultraviolet curing resin 12 protrudes from the transparent substrate 34, this protruding portion is likely to remain on the stamper 33 when the transparent substrate 34 is peeled off. If the protruding portion remains on the stamper 33, the portion that should be bonded to the transparent substrate 34 may also remain on the stamper 33. If the ultraviolet curing resin 12 remains on the stamper 33 in this way, the number of media that can be copied from one stamper will be small, and the life of the stamper 33 will be shortened. On the other hand, if the protruding portion is adhered to the transparent substrate 34, the protruding portion may become flaky and require post-processing.
