Patent ID: 8472298

Claim:
An optical information recording and reproducing apparatus that irradiates a light beam emitted from a light source on to an optical information recording medium having a recording area for recording information by using a holography, the apparatus comprising: a recording process unit which irradiates a signal light beam and a reference light beam for recording information; at least one of a pre-cure process unit which irradiates a predetermined light beam on a desired position on the optical information recording medium prior to irradiating the reference light beam and the signal light beam on to the desired position thereof when information is recorded in the desired position of the optical information recording medium and a post-cure process unit which irradiates a predetermined light beam on to the desired position for making the desired position non-rewritable recordable after the information is recorded in the desired position thereof; and a first driving unit which moves the recording process unit relative to the optical information recording medium, and wherein the first driving unit functions also as a driving unit for moving the at least one of the pre-cure process unit and the post-cure process unit relative to the optical information recording medium, wherein a second driving unit is provided for driving the at least one of the pre-cure process unit and the post-cure process unit independently from moving of the at least one of the pre-cure process unit and the post-cure process unit performed by the first driving unit, and wherein the second driving unit moves in at least a portion of a circumference generally about a center of a lens in the recording process unit.
