Latest Patents

Jong Jun Lee's latest patents focus on methods and apparatuses for judging data writing density on discs. One of his patents describes a data writing density judging method that improves the ability to assess writing density by detecting cross talk and tracking error signals. Cross talk is identified when a disc track is scanned by a beam, while a tracking error signal is noted when a pick-up member jumps a specific track during its movement across a disc track. The improved apparatus computes a ratio between the minimum and maximum values of an envelope signal based on the detected cross talk, allowing for accurate determination of writing density. Additionally, it converts high-frequency analog tracking error signals into digital signals to compute the time required for the pick-up member to jump tracks, further refining the assessment of writing density.
