Latest Patents

One of his latest patents is an optical disk apparatus with a groove/pit area discrimination circuit. This innovative apparatus is designed for recording and reproducing data on optical disks. It features a pit area where data is recorded along a track by pits and a groove area where grooves are formed. The optical disk apparatus includes an optical head that projects a light beam onto the disk and a photodetector array that receives the reflected light. A preamplifier connected to the photodetector array produces a tracking error signal and an RF signal representing the pits. This tracking error signal serves as a clock signal in flip-flops, while the RF signal is used as an initial setting signal, allowing the flip-flop to indicate when the optical head is in the pit area.

Another notable patent involves a focusing control system for use in information recording and reproducing apparatuses. This system performs a focusing control operation to ensure that the beam for reproducing signals is accurately focused on the recording surface of the medium. It includes a differential amplifier that outputs a signal indicating the deviation between the beam's focus and the recording surface. The system also features an amplifier, an A/D converter, and a focusing control driver, all working together to maintain the appropriate focus on the recording surface.
