摘要: A holographic data recording apparatus includes: a signal beam patterning unit for irradiating a signal beam onto a holographic medium, the signal beam including a data pattern to be recorded; a cylindrical optical body including a cylindrical reflective surface, by which a first and a second reference beams alternatively incident thereto at incident angles are reflected toward the holographic medium, alternatively; and an incident angle control unit for controlling the incident angles of the first and the second reference beams incident on the cylindrical optical body, wherein the data, pattern is recorded on the holographic medium by interfering the signal beam with the first and the second reference beams on the holographic medium. The holographic data recording apparatus do not require the replacement of the conventional conical mirrors while recording a plurality of data on a holographic medium, thereby increasing the recording speed and reducing the manufacturing cost thereof.

摘要: A holographic data recording apparatus includes: a signal beam patterning unit for irradiating a signal beam onto a holographic medium, the signal beam including a data pattern to be recorded; and a cylindrical optical body including a cylindrical reflective surface, by which a reference beam incident thereto is reflected toward the holographic medium at a predetermined angle, wherein the data pattern is recorded on the holographic medium by interfering the signal beam with the reference beam on the holographic medium. The holographic data recording speed is increased and the cost of the holographic data recording apparatus is reduced.
