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.

摘要： An optical pickup device includes a light source to emit light, an objective lens to focus the light on a recording medium to form a light spot, an optical path changer on an optical path between the light source and the objective lens to change the path of incident light, a chromatic aberration correction lens disposed on an optical path between the light source and the objective lens, and a photodetector to receive light which is reflected from the recording medium and is then incident thereon through the optical path changer. The chromatic aberration correction lens corrects a chromatic aberration occurring due to a change in the wavelength and/or due to an increase in a wavelength bandwidth of the light. The chromatic aberration correction lens includes at least two lenses such that a lens having a positive power and a lens having a negative power are adjacent to each other.

摘要： A compatible optical pickup for recording and/or reproducing information on/from multiple kinds of optical discs having different thicknesses by selectively using source lights of respective different wavelengths corresponding to a kind of disc and using a common objective lens. At least one phase compensator, which compensates a phase of a light having a particular wavelength to correct for spherical aberration due to a thickness difference between the kinds of optical discs and/or chromatic aberration due to a wavelength difference between the required source lights, is positioned between the source lights and an entrance pupil of the objective lens. Each phase compensator compensates light of at least one wavelength and passes light of at least one other wavelength without significant relative phase alteration. By using two phase compensators, the optical pickup may be made compatible with at least three kinds of optical discs.
