を取り去り信号記録担体を製造する方法である。Generally, methods for manufacturing signal recording carriers include compression press method, injection press method, photocurable resin method, and the like. The photocurable resin method is to place a photocurable resin on a mold, place a transparent substrate on top of it, apply pressure with a press, and press the photocurable resin uniformly between the mold and the transparent substrate. In this method, light is irradiated from the spreader C to cure the entire photocurable resin, and then the mold is removed to produce a signal recording carrier.
この製造法には次のようなでに点がある。先ず第１に、

一になることがある。第８に、これらにより不良が発生
し易く、コストも高くなる。This manufacturing method has the following advantages. First of all,
The signal recording carrier tends to warp due to contraction of the photocurable resin during curing, and furthermore, air bubbles tend to remain. Secondly, depending on the filling state of the photocurable resin, the film thickness of the photocurable resin after being pressurized and cured may become non-uniform. Eighth, these tend to cause defects and increase costs.
