Description
(実施の形態1)
図1は、本発明の実施の形態1に係るホログラム情報記録再生装置の概略構成を示す図である。図中1は、情報記録又は再生用の光を出射する光源を示す。光源1の後段(光路における光の進行方向上の先行する位置)には、光源1から出射された光を2つのコヒーレントな光に分波して、後段に位置する記録媒体3に照射する第1光学系2が配置されている。記録媒体3の後段には、再生信号を受光する第2光学系4が配置されている。受光系4の後段には、記録媒体に情報を多重して記録する際に多重パラメータを変更する多重パラメータ変更手段である波長制御部5が配置されている。
本実施の形態においては、記録媒体3近傍の温度に基づいてレーザ波長を補正してデータ再生を行う場合について説明する。図4は、本発明の実施の形態2に係るホログラム情報記録再生装置の概略構成を示す図である。図4において、図1と同じ部分については、図1と同じ符号を付してその詳細な説明は省略する。
