Media having a recording capacity of MB has been put to practical use. However, the technology of image compression and the like has advanced, and media having several GB or more have been demanded. As for ROM (read only), DVD (digital video disk) has been put to practical use and has realized a large capacity of up to 9 GB. on the other hand,

A pit of recorded information is formed on the surface in a ring shape having a hole with a diameter of about 120 mm and a center with a diameter of about 15 mm. The bonded disk substrate 402 is a substrate on which no information is recorded. An adhesive 404 is applied to the information disk substrate 401 on the table 400 in a ring shape by the application nozzle 403 while rotating the information disk substrate 401 (see FIG. 7A). The bonded disk substrates 402 are superposed and rotated at high speed (for example, about 300
0 rpm) to spread the adhesive 404 over the entire substrate.
Rotate until it is about 0 μm (see FIG. 7B).
Thereafter, ultraviolet light is irradiated from the upper surface of the bonded disk substrate 402 at an illuminance of about 500 mW / cm 2 for 10 seconds to cure the adhesive (see FIG. 7C).

因となる。However, in the case of a DVD-RAM, since a recording film having no light transmission is formed, the DVD-RAM has no light transmission. Therefore, an ultraviolet adhesive cannot be used. Instead of an ultraviolet-curable adhesive, a two-component reaction type, an anaerobic reaction type, a slow-acting reaction type, an adhesive tape, and the like are being studied. Two-component reaction type: Two-component agent A on each of two substrates,
After applying the B agent, it is bonded and reacted and cured. Due to the reaction curing, curing time is required, and when the contact between the two liquids is incomplete, the reaction does not take place and may remain unreacted. Anaerobic reaction type: The reaction proceeds by shutting off the air, but the reaction speed is slow and the adhesive itself is corrosive, so the recording film and reflective film of the disk are damaged, so a protective film is required Becomes Slow-acting reaction type: An epoxy cationic resin is often used. After applying an adhesive to one of the substrates, the substrate is activated by irradiating ultraviolet rays. Thereafter, when the two substrates are bonded together, reaction hardening occurs. In this case, since the reaction time is long and corrosive like the anaerobic reaction type,
A protective film is required. Adhesive tape: A thermoplastic resin is applied as an adhesive to the base film, and a protective film is attached to the upper surface of the adhesive.
In the process, the protective film is peeled off and attached to one disk, then the base film is peeled off and the other disk is attached. Since a thermoplastic resin is used as an adhesive, heat resistance is poor, and there are many indirect members such as a base film and a protective film, which is disadvantageous in cost. Further, at the time of bonding, air bubbles are easily embraced, causing corrosion.

め、金属であればよい。The specific structure of the upper and lower suction plates 109 is shown in FIGS. 8 and 9 with the lower suction plate 109 as a representative. Since the upper suction plate 109 has the same structure as the lower suction plate 109, the description is omitted. The suction plate 109 shown in FIG. 8 has an entire suction surface formed of a single plane, and has a surface accuracy of at least 5 /
About 100 mm is required. As the suction surface, the entire suction surface does not need to be formed by one plane, but a plane is required at least in the center hole portion where no recording film is provided. For example, as shown in FIG. 9, an annular suction plane having suction holes 109a may be arranged at the center hole portion and the outer peripheral portion where there is no recording film. 290 is the suction hole 10
This is a suction device for driving suction from 9a. By driving this suction device 290, suction is performed from the suction hole 109a,
The disk substrate 102 can be sucked on the suction plate 109. The suction pressure depends on the shape of the suction plate 109, but if the suction pressure is too large, the hole shape or the groove shape will be transferred to the substrate. Therefore, the suction pressure is preferably -30 mmHg or more. The shape and density of the suction holes formed in the suction surface are not particularly limited, but are hardened while being sucked. If the edges of the holes are sharp, the substrate may be damaged, which is not preferable. Since the material of the suction plate may be deformed by heat due to ultraviolet rays, any metal may be used to prevent the deformation.

In the step (b), the curing is performed after laminating a plurality of disks 190 without curing the entire adhesive because it takes time to apply ultraviolet light from the lateral direction and to cure to the center of the disk. This is because if a plurality of sheets are laminated and then cured, the production efficiency can be improved. However, the reason for curing only a part first is to avoid deformation of the disks when stacked.
