Latest Patents

One of Isato's latest patents involves an optical storage device designed to be thinner by substituting electrical means for the capabilities of sensors. This invention allows for the positioning of a lens carriage and objective lens without the need for position sensors, thereby reducing the thickness of the optical disk unit. The device ensures that when a seek operation begins, the carriage accelerates and decelerates smoothly, positioning itself accurately on the target track. Additionally, it minimizes vibrations of the lens actuator during the seek process and locks the actuator in the center of the carriage. A false lens signal is generated during the seek operation, which helps maintain the actuator's position effectively.
