Abstract: An apparatus for controlling an incident angle of reference beam and a holographic information recording/reproducing apparatus having the same are provided to change only the incident angle while maintaining the incident position of the reference beam. A reference beam incident angle control apparatus(30) comprises a first lens device(31) and a driving part(33). The first lens device projects reference beam to a holographic recording medium. The driving part is moved in the direction perpendicular to an optical axis to change the incident position of the reference beam in the radial direction on the first lens device. The incident angle of the reference beam projected to the holographic recording medium is determined by the incident position of the reference beam in the radial direction on the first lens device. The driving part includes a spot forming member for forming a spot by focusing the reference beam, and a mirror(32) for reflecting the reference beam into the first lens device in parallel to the optical axis.

Abstract: An apparatus and a method for recording data on a holographic storage medium are provided to form selectivity difference among the parts of an SLM(Spatial Light Modulator) surface by forming the tangential side of the SLM surface longer than the radial direction along which the reference light is scanned, thereby reducing the recording gap. A holographic recording and reproducing device comprises an optical processing part(510) in which a holographic storage medium(100) is inserted, a control part(520) for controlling the optical processing part to record data in the holographic storage medium or reproducing the data from the medium, and a memory(530) for storing the data to be recorded in the holographic storage medium temporarily. The optical processing part includes a laser light source(511), a beam splitter(512), a first reflection mirror(513), a spatial light modulator(514), a first lens(515), a second reflection mirror(516), a second lens(517), a third lens(518), and a detection part(519). The control part controls the optical processing part, generates a data page, and processes a signal reproduced from the optical processing part. The signal light is projected to the spatial light modulator. The signal light is modulated. The modulated signal light is focused on the holographic storage medium by the first lens. The reference light is reflected from the second reflection mirror. The tangential direction is longer than the radial direction in which the reference light is scanned on an SLM(Spatial Light Modulator) surface.
