An optical information recording medium characterized in that a recording plate, a substrate , or another recording plate and a spacer are bonded together with an ultraviolet curing adhesive.

Claims

[Scope of utility model registration request]

In order to integrate a recording plate with an information recording layer on one side with a substrate, a spacer member is attached to the inner periphery of the recording plate and the substrate, and a space is gradually formed between the recording plate and the substrate along the outer periphery of the spacer member. 1. An optical information recording medium characterized in that a tapered portion is provided so that the angle becomes larger, and a recording plate, a substrate, and a spacer are bonded using an ultraviolet curing adhesive.
