Latest Patents

Kato holds a patent for an "Optical record medium reading apparatus having a de-focussed light beam." This apparatus includes a semiconductor laser diode for emitting a laser beam, a collimator lens, a beam splitter, an objective lens, a converging lens, and a photodetector. The design allows the laser beam emitted from the laser diode to be incident upon the optical record medium through the collimator lens, beam splitter, and objective lens. The reflected light flux from the optical record medium is then directed to the photodetector via the objective lens, beam splitter, and converging lens. Notably, the laser diode and collimator lens are arranged to project the laser beam onto the optical record medium in a de-focused condition, while the objective lens remains in focus on the medium.
