て情報記録担体を製造する。In the above conventional example, the tangzu stun g1 is 200 to 30
Since it is as thin as 0 μm, the backing material 2 is bonded to the back surface and reinforced to maintain flatness. Next, apply ultraviolet curing resin 5 concentrically with the signal track of the stand 1. The transparent substrate 3 is then lowered in the direction of arrow a while being guided by the center gear 4 to roll the ultraviolet curing resin 5. Thereafter, the transparent substrate 3 and the ultraviolet curing resin 5 are integrated by irradiation with ultraviolet rays to produce an information recording carrier.
しかしながら上記のような方法では、紫外線硬化樹脂５

る。Figure 3 shows a specific example of superimposing a transparent substrate coated with an ultraviolet curable resin and a star/rig in the manufacturing method of the present invention. In the figure, 9 is a fulcrum, and 10 is a speed adjustment. Possible vertical mechanism, 11 rotates around the fulcrum 9 i
The transparent substrate 3 is held by the +J functional arm and is lowered by the vertical mechanism 10. Other details are the same as in Figure 1. The transparent substrate 3 coated with the ultraviolet curable resin 5 is turned over, held by an arm 11, and stacked on top of each other by a vertical mechanism 10 while adjusting the speed. The descending speed of the vertical mechanism 10 is as follows:
The contact start point 7a and the contact end point 71) are stun・'e1
The speed is set to low near the point where it touches the surface, and high speed is set in between.

になることを防止できるものである。FIG. 4 shows an example of applying an ultraviolet curable resin onto a transparent substrate in the manufacturing method of the present invention. Apply so that the amount applied is small. In this way, by setting the amount of coating near the contact starting point 7a to be small, the ultraviolet curing resin 5 flows toward the contact starting point 7a side due to the inclination of the transparent substrate 3 during stacking, and the transparent substrate 3 after rolling. This can prevent the amount of the ultraviolet curable resin 5 from protruding from being uneven.
