Claims (1)
ペーサーにより２枚の円板状基板が対向して設け
られ、これら基板とスペーサーとが接着剤により
一体に結合されるとともに、少なくとも１枚の透
明な基板の内側に記録膜を有する光記録媒体にお
いて、内周スペーサーは同心円状に配置された複
数の内周スペーサーからなり、かつ隣接する内周
スペーサーには同心円の中心に対し９０°乃至１
８０°の角度の範囲に孔、スリツト等の間隙が設
けられていることを特徴とする光記録媒体。 Two disc-shaped substrates are provided facing each other by an inner circumferential spacer and an outer circumferential spacer arranged concentrically, and these substrates and spacers are integrally bonded with an adhesive, and at least one transparent substrate is provided. In an optical recording medium having a recording film inside, the inner circumferential spacer is composed of a plurality of inner circumferential spacers arranged concentrically, and adjacent inner circumferential spacers have an angle of 90° to 1° with respect to the center of the concentric circle.
An optical recording medium characterized in that gaps such as holes and slits are provided in an 80° angle range.
