摘要： An optical pickup apparatus which reduces cross talk by adjacent tracks. The optical pickup apparatus divides light reflected from an optical recording medium as a spot into center and side portions defined with respect to the radial direction of the recording medium and provides electrical signals corresponding to the reflected light in divided form. An operation unit multiplies signals corresponding to the side portions by an operation constant, adds the multiplication results and the detected signal of the center portion, and outputs an information signal of a main track with reduced cross talk by adjacent tracks in real time. The optical efficiency is sufficient that recording of an information signal can be performed with the optical pickup.

摘要： An optical pickup compatible with optical discs having different formats. A first light source emits a first light beam suitable for a first format optical disc. An objective lens is optimized for a wavelength of the first light source. Light reflected from the first optical disc provides a reproduction signal. A second light source emits a second light beam suitable for a second format optical disc. A light splitter splits the second light beam and the objective lens focuses the split beams onto the second disc as a main light spot and a sub-light spot. Lights reflected from the main light spot and the sub-light spot are independently detected and then processed to correct for chromatic aberration caused by a difference in the wavelengths of the first and second light beams and/or spherical aberration caused by thickness difference between the first and second format optical discs.

摘要： An optical pickup assembly having an elastically supported tilt mechanism. The optical pickup assembly includes a bobbin at which an objective lens is mounted and an elastic support member which supports the bobbin in elastic motion with respect to a holder installed at a base. A focus coil and a tracking coil are installed at the bobbin and form a conducting path for driving the objective lens in a focusing direction and a tracking direction. Tilt coils are installed at one side of the bobbin and form a conductive path for driving tilt of the objective lens. A first magnet and a first yoke generate an electromagnetic force to driving the objective lens together with the current carrying focus coil and tracking coil. A second magnet and a second yoke generate an electromagnetic force to driving the objective lens together with the current carrying tilt coils. A position detecting sensor measures relative inclination of the objective lens with respect to a disk, and a balance member coupled to the bobbin to balance the weight of the tilt coils by applying weight corresponding to the weight of the tilt coils at positions symmetrically opposite to the positions of the tilt coils.
