Latest Patents

One of Ohe's latest patents focuses on an optical disk device designed to reproduce signals from a double-layer optical disc with two signal recording surfaces. This invention emphasizes the necessity of a quick focus jump, allowing the objective lens to shift from one recording surface to another efficiently. The process involves monitoring a focus error signal (FE) and supplying a deceleration signal to the actuator when the signal reaches a predetermined threshold. The deceleration pulse voltage is adjusted step by step based on the maximum value of a differential focus error signal. Additionally, the invention allows for simultaneous address seeking during the focus jump, which is performed according to a pre-measured layer-to-layer distance. The system also includes a mechanism to determine which layer is being accessed based on reflected luminous power, ensuring accurate signal reproduction.
