摘要：
A hologram recording apparatus includes an objective lens (7) for illuminating a hologram recording medium (B) with a recording beam (S) in a manner such that the recording beam overlaps a reference beam, thereby performing multiple recording of holograms at a portion illuminated with the reference beam and the recording beam (S). The objective lens (7) includes at least one rotationally symmetric lens (7A, 7B), and at least one rotationally symmetric lens (7A) is so arranged that the lens optical axis is inclined with respect to the direction (S1) in which the recording beam (S) travels.
