Abstract

　３次の球面収差を補正する際に発生する波面収差の影響を抑制し、良好な情報の記録及び／又は再生を実現する。 　コリメータレンズ４は、第１の対物レンズ６に平行光が入射した時に残存する３次の球面収差が最小となる第１の光情報記録媒体３０の光透過層厚を第１の対物レンズ６の最適基材厚とし、第１の対物レンズ６の最適基材厚に対応する第１の光情報記録媒体３０の面から所望の情報記録面までの光透過層の厚さに応じて発生する３次の球面収差を補正し、第１の光情報記録媒体３０の第１の対物レンズ６から最も遠い情報記録面において３次の球面収差補正時に発生する波面収差の変位量と、第１の光情報記録媒体３０の第１の対物レンズ６から最も近い情報記録面において３次の球面収差補正時に発生する波面収差の変位量とが同等となるように、第１の対物レンズ６の最適基材厚が定められる。
