摘要： A compatible optical pickup includes an optical disc, an objective lens, a diffractive device, and a divergent lens. The optical unit emits a short wavelength light beam corresponding to a high density optical disc and a long wavelength light beam corresponding to a low density optical disc. The objective lens forms a light spot on the high density optical disc and the low density optical disc and the diffractive device diffracts the short wavelength light beam to correct chromatism according to a change in a wavelength of the short wavelength light beam. The divergent lens refracts the long wavelength light beam toward the objective lens to increase a working distance with respect to the low density optical disc.

The active compensation device includes a plurality of transparent substrates, and at least one material layer, interposed between the plurality of substrates, having a refractive index which is actively switched according to an applied voltage. A holographic pattern, formed adjacent to the material layer on a surface of at least one of the transparent substrates, changes a divergence angle of the light by diffracting or transmitting without diffraction the incident light according to change of the refractive index of the material layer. The voltage applied to the material layer is adjusted according to the applied information storage medium that is adopted for the use in the data recording/reproducing operation.
