摘要： An optical pickup capable of reducing cross-talk due to signal interference of adjacent tracks of an optical medium during playback of a radio frequency (RF) signal from a main track of the optical recording medium. In the optical pickup, optical spots can be converged on the main track and the adjacent tracks of the recording medium without a time lag, wherein different polarized component beams are focused as a primary optical spot and secondary optical spots on the main and adjacent tracks, respectively, of the optical recording medium. Thus, the primary optical spot and the secondary optical spots, which have different polarized components, can be separately received by different light receiving portions. Also, the optical spots are photoelectrically converted in the light receiving portions and are differentially amplified through multiplication using a predetermined operation constant, thereby reducing cross-talk from a detected RF signal. For the convergence of optical spots on the adjacent tracks without time lag relative to the optical spot formed on the major track, a beam shaping unit having a shield plate, or transmission or reflection type phase difference prism is adopted.

摘要： An optical pickup compatible with a plurality of optical recording media each using light of a different wavelength. The optical pickup includes at least one light source, an objective lens having a function of focusing light emitted from the light source into the optimal light spot on an information recording surface of one of the plurality of the optical recording media, and a light detector to detect light transmitted through the objective lens after being reflected from the information recording surface of the optical recording medium on which the light spot is formed. The objective lens has an inner area, an annular lens area and an outer area such that the annular lens area divides the inner area from the outer area and has a ring shape centered at a vertex. The inner area, the annular lens area and the outer area have aspherical surface shapes to focus light transmitted through the inner area and the outer area into a single light spot by which information can be read from the information recording surface of a relatively thin first optical recording medium and scatter light transmitted through the annular lens area located between the inner area and the outer area so that information cannot be read from the information recording surface of the first optical recording medium, during reproduction of the first optical recording medium. The inner area and the annular lens area transmit light into a single light spot by which information can be read from the information recording surface of a relatively thick second optical recording medium and scatters light transmitted through the outer lens area so that information cannot be read from the information recording surface of the second optical recording medium, during reproduction of the second optical recording medium.

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.
