摘要： An optical pick-up apparatus and method incorporating a spherical aberration compensator is disclosed. The optical pick-up employs the spherical aberration device that comprises a wave plate for converting the phase of beams entering the wave plate and outputting the phase-converted beams; and a liquid crystal panel having a molecular structure for adjusting the phase of circularly-polarized beams, whereby it is possible to compensate for the spherical aberrations of the laser beams emitted from a light source and entering an optical recording medium, and the laser beams which are reflected from the optical recording medium and reenter the liquid crystal panel. As a result, jitter characteristic of the optical pick-up can be enhanced.
