特徴とする光情報記録媒体。 A pair of disk substrates, at least one of which has an information recording layer, and an annular inner circumferential spacer and an annular outer circumferential spacer that respectively support the inner and outer circumferential portions of the disk substrates and face each other in parallel so that the recording layer is on the inside. and an adhesive layer for bonding the disk substrate, the inner circumferential spacer, and the outer circumferential spacer to each other;
In an optical information recording medium comprising a bubbling layer formed between both disk substrates, a part of the disk substrate facing the spacer and/or a part of the upper surface or a part of the lower surface of the spacer or the like. An optical information recording medium characterized in that a portion of both surfaces is made of a material that has poor affinity for an adhesive used for forming an adhesive layer.
