Title: Innovations of Jin-Chuan Hsu
Introduction
Jin-Chuan Hsu is a prominent inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of optical storage systems, holding a total of 5 patents. His work focuses on enhancing the performance and reliability of optical disc recorders.
Latest Patents
One of his latest patents is a method and device for canceling a land-groove offset component of a focusing error signal in an optical storage system. This device includes first and second circuits, along with an adder. The first circuit processes a radio frequency ripple signal to obtain a first processed signal, which is then multiplied by a first gain value to produce a first signal. The second circuit processes a tracking error signal to obtain a second processed signal, which is also multiplied by a second gain value to create a second signal. The adder combines these two signals to generate a compensative land-groove offset component, enabling the focusing device to cancel out the offset component of the focusing error signal.
Another notable patent is a shock detector for optical disc recorders and a shock-proof recording method using a shock signal. This shock detector comprises a first detecting unit that measures the amplitude of a reference signal, a second detecting unit that assesses the level of another reference signal, and a third detecting unit that monitors the revolution of yet another reference signal. A judging unit processes these signals and activates a shock signal when all three detecting signals are simultaneously enabled, eliminating the need for an additional shock sensor.
