Latest Patents
Jong-kook Lee holds a patent for an "Optical pickup apparatus and optical recording/reproducing system using the same." This invention includes an optical pickup apparatus that features at least two optical systems designed for different types of optical recording media. One of the objective lenses is offset from the central line of the optical recording medium. The optical system with the offset objective lens utilizes a diffraction grating that diffracts light emitted from a light source to create a main beam and sub-beams. The diffraction grating consists of first and second diffraction regions with different grating patterns arranged alternately, ensuring that the center of each sub-beam is positioned at the boundary of these regions. This design allows for the alignment of the center of the diffraction grating with the optical axis of the light source, effectively preventing the generation of an alternating current in the Push-Pull signal of the sub-beams.
