| 20080219128 | OPTICAL PICKUP, OPTICAL INFORMATION RECORDING AND REPRODUCING APPARATUS AND METHOD FOR OPTICALLY RECORDING AND REPRODUCING INFORMATION - An optical pickup for recording a hologram by using an angle multiplexing method. An optical beam is separated into two beams, a signal beam and a reference beam having different convergence/divergence degrees, by using an optical component such as a diffraction lens. The signal and reference beams are made incident upon the same objective, and the optical component or the objective lens is moved in a direction perpendicular to an optical axis, to thereby realize angle multiplex recording. If an optical information recording medium is inclined, the optical component or the objective lens is moved along the direction along which the optical information recording medium moved to change an angle of the reference beam incident upon the optical information recording medium and compensate for degradation of a reproduction signal. | 09-11-2008 |
