Latest Patents

One of Hino's latest patents is an optical pickup position control device. This innovative device automatically adjusts tracking with precision and in a short time. It utilizes two deviation signals that express the deviation of a light beam projected by a pickup using the three-beam method from a target track of a disk. These signals are digitized by two AD converters. High-pass filters extract AC signals from the deviation signals, producing a tracking error signal. Additionally, low-pass filters extract DC signals and low-band signals containing DC components. A control circuit then calculates correction values to be applied to offset correcting circuits and gain/balance correcting circuits, allowing for collective and simultaneous corrections based on these values.
