Abstract

　情報記録層数が少ない旧規格の光情報記録媒体に対応している駆動装置でも再生可能とし、旧規格の光情報記録媒体にＲＯＭ層又はＲ層を追加することにより記録容量を向上させるため、再生光の入射側から順に、透光層（１０）、第１情報記録層（２０）、中間層（３０）、第２情報記録層（４０）及び基板（５０）が積層された構造となっており、第１情報記録層（２０）がＲＯＭ層又はＲ層であり、第２情報記録層（４０）がＲＥ層である。そして、第１情報記録層（２０）は、透光性を有し、第１情報記録層（２０）の再生光波長における反射率の値は、０．４％より大きく２．２％以下であり、ＲＯＭ層又はＲ層である第１情報記録層（２０）の第１情報記録領域には、再生光の入射方向に対して第２情報記録層（４０）の第２情報記録領域と重ならない第１情報記録層認識エリアが存在している。
