填されていることを特徴とする情報記録媒体。 A pair of substrates having a recording layer on one side of at least one of the two disc-shaped substrates are bonded together with the recording layer facing inside through an inner circumferential spacer and an outer circumferential spacer arranged concentrically. In an information recording medium having an air sandwich structure, holes penetrating through at least one substrate are provided at positions corresponding to the bonding portions of the inner circumferential spacer and the outer circumferential spacer of both substrates, respectively,
On the other hand, the inner circumferential spacer and the outer circumferential spacer are provided with protrusions having the same cross section as the hole cross section at the contact surface between the substrate and the spacer at positions corresponding to the holes in the substrate. Each protrusion of the spacer is in a fitted state, and the gap between the hole and protrusion in each fitting part is filled with a filler so that the surface of the information recording medium is flat overall. An information recording medium characterized by:
