Title: The Innovations of Tadashi Taniguchi
Introduction
Tadashi Taniguchi is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of optical technology, holding a total of 17 patents. His work primarily focuses on optical devices that enhance data recording and retrieval processes.
Latest Patents
Among his latest patents are the optical head device and the optical recording/reproducing device. The optical head device features a compact and lightweight flying head type magneto-optical head apparatus. This innovative apparatus includes a suspension fixed to the lower surface of an arm, a slider attached to the free end of the suspension, and both a magnetic modulation coil and an object lens mounted on the slider. The slider floats due to wind pressure generated by the rotation of a magneto-optical disk. Additionally, the device incorporates a collimeter lens that can be adjusted vertically along the optical axis, improving optical conditions between the light source and the object lens.
The optical pickup and optical disk drive patent introduces a diffraction element positioned between a semiconductor laser and a collimator lens. This design ensures that only the zero-order light is focused on the optical recording medium, allowing for variable diffraction efficiency. By adjusting the diffraction efficiency, the optical pickup device can utilize light with varying efficiency without requiring a larger design.
