本発明は、情報記録層を有する円盤状の情報配録ディス
クの製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method of manufacturing a disk-shaped information recording disk having an information recording layer.
従来から情報記録ディスクの貼り合わせ方法では、紫外

、気密性及び接合力に優れ、変形の少ないディスクを提
供することが要求されている。Conventionally, methods of bonding information recording disks using ultraviolet curing or thermosetting resin adhesives have been known (Figure 4).These methods ensure that the bonding layer is uniform and airtight. There is also a need to provide a disk with excellent bonding strength and less deformation.
そこで、均一な接合層を得るために、貼り合わせ時ディ
スクの外周に厚さ規制部材を用いたり（特開昭５９−４
０３４０）、貼り合わせ後変形させないように恒温槽で
常温にて長時間かけて硬化させる方法がよく知られてい
る（第５図）。Therefore, in order to obtain a uniform bonding layer, a thickness regulating member was used on the outer periphery of the disk during bonding (Japanese Patent Laid-Open No. 59-4
0340), a well-known method is to cure the materials at room temperature over a long period of time in a constant temperature bath to prevent deformation after bonding (FIG. 5).
しかしこのような従来の方法では、硬化に時間を要する
ために、生産性が低く、しかも厚さ規制部材はディスク
の給１［Ｊに支障を生じさせるという間組点を有してい
た。However, in such a conventional method, productivity is low because hardening takes time, and furthermore, the thickness regulating member has a set point that causes a problem in the feeding of the disk.
本発明は、従来のこのような問題点を解決するもので、
その目的とするところは、接合層を早く均−にでき、し
かも硬化に要する時間を大幅に短縮できる製造方法を提
供することである。The present invention solves these conventional problems,
The object is to provide a manufacturing method that allows the bonding layer to be quickly leveled and to significantly reduce the time required for curing.

とする。The information recording disk manufacturing method of the present invention includes the steps of filling two disk substrates having an information recording layer on at least one side with the recording layer inside and filling an adhesive between the substrates, and then bonding them together to create an information recording disk. , a heating mechanism is provided in at least one of the pressure mechanisms, and has a function of applying pressure while heating the adhesive according to a heating program that keeps the viscosity of the adhesive constant, and further changing the pressing force in stages.

いディスクが得られ、しかも接着剤の硬化に要する時間
を大幅に短縮できる。According to the method of the present invention, a disk with a uniform bonding layer and no deformation can be obtained, and the time required for curing the adhesive can be significantly shortened.

貼り合わされる。FIG. 1 is a main sectional view of a bonding apparatus according to an embodiment of the present invention. Upper disk 11 and lower disk 12,
This is a device for bonding the disks together using a thermosetting adhesive 13, and a heater 15 is incorporated inside the upper disk holder 14. The two disks are bonded together by a pressure cylinder 16.
ここでヒーター１５は接着剤１３の粘度を最適状態にし
て、一定に保持するように、接着剤１３の温度を変化さ
せる。Here, the heater 15 changes the temperature of the adhesive 13 so that the viscosity of the adhesive 13 is optimized and maintained constant.
圧着用のシリンダ１６は、接着剤１３を早く均一につぶ
すために、加圧力を段階的に変化させる。The pressure cylinder 16 changes the pressing force in steps in order to crush the adhesive 13 quickly and uniformly.

剤の粘度を最適状態に保つ。FIG. 2 is an example of a heating program for the heater 15 to maintain the viscosity of the adhesive 13 at an optimum level. As the adhesive 13 hardens, the temperature is accelerated, maintained, and lowered to maintain the viscosity of the adhesive at an optimal state. Keep it.
これにより接着剤１３は、加速硬化する。As a result, the adhesive 13 is acceleratedly cured.

。FIG. 3 shows an example of a pressure program for the cylinder 16 to quickly and uniformly crush the adhesive 13. In order to prevent the load applied per unit area from decreasing as the adhesive 13 collapses and the area increases, The applied load is increased as time passes. This makes it possible to shorten the adhesive pressure bonding time. Furthermore, since the load applied initially is small, the bonding deviation is reduced. Furthermore, since the diffusion rate of the adhesive 13 is constant, air bubbles are less likely to enter.
