Title: Yutaka Saito: Innovator in Optical Disc Technology
Introduction
Yutaka Saito is a notable inventor based in Kawaguchi, Japan. He has made significant contributions to the field of optical disc technology, holding a total of 3 patents. His work has been instrumental in advancing the functionality and efficiency of optical disc apparatuses.
Latest Patents
One of Saito's latest patents is an optical disc apparatus featuring an automatic gain control circuit. This innovative apparatus generates a tracking error signal and a focusing error signal for an objective lens. Additionally, it produces a tracking sum signal or a focusing sum signal for the objective lens. The apparatus multiplies the sum signal by the tracking error signal and the sum signal by the focusing error signal. Based on the results of these multiplications, the apparatus moves the objective lens in both the tracking and focusing directions.
Another significant patent is the laser beam control apparatus. This invention includes a photodiode that outputs a current consisting of high and low-frequency components, which correspond to the amount of laser beam emitted from a laser diode. The current from the photodiode is separated into high and low-frequency components using a CR filter. The low-frequency current is amplified, and this amplified current is added to the high-frequency current. The resulting sum current is then converted into a voltage, allowing for stable control of the laser beam output power across a wide range.
