Latest Patents

One of Adachi's latest patents is an optical pickup that includes a diffraction grating, a beam splitter, and laser beam guiding optical components. This invention changes the direction of laser beams placed on a light path constituted by a semiconductor laser that emits dual wavelength laser beams. A wavelength plate is provided on the light path between the diffraction grating and the semiconductor laser, allowing the laser beam to become an elliptically polarized beam or a beam with a polarizing plane at a specific angle relative to the radius direction of the optical disk.

Another significant patent is a rotary magnetic head inspection method designed for a double azimuth head. This method involves two magnetic heads of different azimuthal angles arranged on a head base. The process includes recording an inspection signal on a running tape, reproducing the signal to check the level, and verifying the correct assembly of the magnetic head onto the head base through the judgment of the reproducing signal.
