Title: The Innovations of Tosihiko Otomo
Introduction
Tosihiko Otomo is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of optical technology, particularly in the development of devices that enhance the functionality of optical disk apparatuses. With a total of 2 patents to his name, Otomo's work reflects a deep understanding of both engineering and practical applications in technology.
Latest Patents
Otomo's latest patents include a "Recording medium transducing light spot moving velocity detection circuit." This innovative circuit is designed to detect the moving velocity and direction of motion for an optical spot. The detectors provide sine wave signals that have periods inversely proportional to the moving velocity, with phases that are advanced or delayed opposite the direction of rotation. Deformed and differential signals derived from the detection signals are utilized to create half wave signals, which are then combined in a predetermined manner. The polarity of these signals indicates the direction of movement, while the absolute value indicates the velocity.
Another significant patent is the "Optical spot position detection device for an optical disk apparatus." This device is capable of detecting the track position of an optical spot on the recording tracks of an optical disk. It achieves this by dividing the space between the centers of adjacent recording tracks into four areas, indicating which of the four areas the optical spot occupies. This functionality allows for the provision of a control signal for the optical spot.
