Abstract
A hologram recorder (A) records holograms in a selected unit recording area (B) of a hologram recording medium (B) by interference between a recording beam (Lr) which is applied vertically to the unit recording area (B) and a reference beam (Lr) which is applied obliquely to the unit recording area (B). The hologram recorder (A) includes a reference beam oblique applier (A,B) for application of the reference beam (Lr) obliquely to the unit recording area (B) by reflection, and a reference beam swing mechanism () for supporting the reference beam oblique applier (A,B) and for swinging the reference beam oblique applier (A,B) about a predetermined rotation axis which is perpendicular to an entering direction of the recording beam (Lw) that makes an entry into the unit recording area.
