Latest Patents

Woo-min Jung's latest patents include a method and apparatus to detect land/groove switch position in seek mode. This innovative method involves measuring information about the land/groove switch generation timing of a disc. It utilizes a first signal with a frequency that varies in proportion to the rotation speed of the disk during normal playback. Additionally, a second signal with a predetermined frequency higher than the first signal is employed to calculate a predicted land/groove switch generation position in seek mode. Another notable patent is for high-speed focus pull-in controllers that adaptively respond to disk surface vibration in optical disk devices. This technology detects and stores upper and lower limit values of disk surface vibration while a signal is reproduced. If the focus deviates from an initially set allowable range, a focus repull-in operation is performed based on the previously stored vibration values.
