Abstract

　レーザ光源から出射されたレーザ光を２つに分割し、分割された２つのレーザ光の一方に対して、記録情報に基づいて２次元の空間変調を施し、これを信号光として記録媒体に照射するとともに、他方を参照光として記録媒体に照射して、記録媒体に記録情報を記録し、一方、記録媒体を透過又は反射したレーザ光に基づいて記録媒体に記録された記録情報を再生するホログラム記録再生装置であり、レーザ光の照射光路上には記録処理過程において光源から出射されたレーザ光の通過を遮断する遮光手段が設けられている。該遮光手段には、少なくとも１つのスリットが形成されてなる通過領域と、該スリットが形成されていない領域に対応する遮光領域とからなるスリットパターンが形成され、これが回転駆動することにより該通過領域と該遮光領域とが交互にレーザ光の照射光路をよぎる。
