Latest Patents

Mitsuhiko Oohta holds a patent for an "Optical disc apparatus and method for reading information from an optical disk having tracks and spaces between the tracks on which address information is recorded." This invention involves an optical disc apparatus that reads address information from an optical disc with tracks and track spaces. The apparatus features an optical head that irradiates the disc with light and includes tracking detectors. These detectors are divided into a first detector and a second detector in the track direction, which detect the light reflected from the disc and output detection signals. An adjusting circuit adjusts the amplitudes of these detection signals, while a differential amplifying circuit outputs a differential signal based on the adjusted signals. The address detecting circuit then detects the address information based on this differential signal. This technology significantly improves the accuracy of information recording on the correct track, enhancing reliability during the recording process. Mitsuhiko Oohta has 1 patent to his name.
