Title: Mitsuyuki Kimura: Innovator in Optical Disc Technology
Introduction
Mitsuyuki Kimura is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of optical disc technology, holding a total of 3 patents. His work focuses on enhancing the functionality and precision of optical disc devices.
Latest Patents
One of Kimura's latest patents involves an optical disc device that features a circuit designed to form a focus error signal for focus servo control. This signal is generated based on reflection light from an optical disc that is exposed to laser light. The device includes a data processing unit that can control the position of an objective lens moved by a focusing actuator, utilizing feedback based on the focus error signal. In the context of label printing, the data processing unit employs feedforward control to adjust the position of the objective lens based on control data for label printing. Notably, the operational resolution of the focusing actuator in feedforward control is enhanced compared to feedback control, achieving greater position control accuracy. For instance, during feedforward control, the gain of the driver circuit for the focusing actuator is switched to a smaller value compared to that used in feedback control.
