Overlap the protective boards without aligning them on the center axis. This is left to stand naturally, and the weight of the protective substrate allows the adhesive to fill the entire surface between the two substrates, allowing the adhesive to harden and bond the two substrates together. This method has the disadvantage that air bubbles are mixed in when the adhesive is applied or when the protective substrates are stacked together and tend to remain in the adhesive layer until after the adhesive has hardened. For example, Japanese Patent Laid-Open No. 61-50231 is proposed to solve this drawback.

Since it twists deeply, it comes out of the two disk boards. Also, depending on the type of adhesive, viscosity, and amount of application, it is necessary to change the speed at which the disk substrates are stacked and the degree of inclination. It can be arbitrarily selected and set using the angle adjustment means.

後、常温で接着剤を硬化させた。In a normal pressure environment, place the disk substrate (1) with a diameter of 130 mm horizontally on the support stand (4) through the center axis (5), and apply adhesive (3) to the disk substrate (1).
) was applied in a donut shape on a circumference with a radius of 40 mm. From above, place the disk substrate (2) opposite to the disk substrate (2) through the center shaft (5) and place one end on the disk substrate <1).
2) was tilted. The axis (60) is tilted toward the disk substrate installation side from being approximately parallel to the side connecting the other end of the disk substrate <1) and the other end of the disk substrate <2. In other words, the disk substrate (1) The degree of engagement between the protruding piece (71) and one of the disk substrates (2) will be the same as the degree of engagement at the start when both substrates are overlapped. It behaves in such a way that it becomes the same or shallower compared to others. Therefore, the above disk substrate (2)
While holding the other end with the protruding piece (71) of the holding means 7) provided on the driving means <6), lower the two disk substrates H), (2) at a speed of 1 mm/sec. are placed one on top of the other, and the protruding piece (71) is retracted to release the engagement with the disk substrate. At this time, after confirming that the intervening adhesive was spread throughout the disk substrate (2) under its own weight, the adhesive was cured at room temperature.
