製造する方法である。Normally, there are compression press method, injection press method, photocurable resin method, etc. for manufacturing signal recording carriers.The photocurable resin method is as shown in Figure 1.
A photocurable resin (3) is placed on the mold (2) on υ, a transparent substrate (1) is placed on the mold (2), and a C photocurable resin (1IivDI) and a transparent substrate ( 4) is pressurized with a press machine (6), and after the pressure is released, light is irradiated from the °C light source (7) through the transparent substrate (4) to harden the photocurable resin (3), and then the mold is removed. This is a method of manufacturing a signal recording carrier by removing (2).

する。第６に、コストが高い。This manufacturing method has seven points as follows. First of all,
If the resin is cured with the pressure released, the film thickness of the photocurable resin will become thick and uneven. Second, the signal recording carrier tends to warp due to shrinkage of the photocurable resin during curing. Eighth, when the pressure is released, the return of the photocurable resin tends to cause bubbles and other fires at the ends of the resin. Fourthly, when a thin mold is used, the signal surface will also warp due to the warp of the mold. Fifth, a large amount of photocurable resin is required. Sixth, the cost is high.

A transparent hinyl chloride plate was used as a mold (11) using a photocurable resin (6) and a curable resin of 10 degrees Celsius with a diameter of 8°C.
Using a mercury lamp of C1 type with light source 0I111, press the boiled glass plate of press machine 0 from above to pressurize it to 4kg/cyj, turn on the mercury lamp for 1 minute in that state, and cure with ultraviolet rays. The mold resin was cured. After curing, the copper mold was removed to prepare a signal recording carrier.

Furthermore, the uniformity could be improved from ±50 μm to ±10 μm.
本発明信号記録担体の製造法は以上述べたように実施し
得るもので次に述べるような効果が得られる。The method for manufacturing the signal recording carrier of the present invention can be carried out as described above, and the following effects can be obtained.
■ 加圧状態を保持したまま光硬化型樹脂を硬化させる
ので光硬化型樹脂の膜厚を半分以下にでき、更にその膜
厚分布も非常に均一にできる。(2) Since the photocurable resin is cured while maintaining the pressurized state, the film thickness of the photocurable resin can be reduced to less than half, and the film thickness distribution can also be made very uniform.
又光硬化型樹脂の硬化時の収縮による信号記録担体の反
りも起らない。Further, the signal recording carrier does not warp due to contraction of the photocurable resin during curing.
■ 厚みの薄い金型を用いＣも、金型の反りの影響を受
けないので信号記録担体の信号面の反りがない。(2) Since a thin mold is used, the signal surface of the signal recording carrier does not warp because it is not affected by warping of the mold.
■ 光硬化型樹脂が硬化するまで圧力を解除しないので
光硬化型樹脂の戻りがなく、気泡が生じない。■ Since the pressure is not released until the photocurable resin is cured, there is no return of the photocurable resin and no air bubbles are generated.
■ 装置を小型化できる。■ The device can be made smaller.
■ 光硬化型樹脂の種類により物理的な特性（特に粘性
）が変化しても容易に対応することができる。■ Easily adaptable to changes in physical properties (particularly viscosity) depending on the type of photocurable resin.
■ これらにより光硬化型樹脂の使用量を少なくでき、
行程も簡易化できるのでコストを下ケることが“できる
。■ These allow us to reduce the amount of photocurable resin used,
Since the process can be simplified, costs can be reduced.
