Latest Patents

Ogura holds a patent for a "Timing signal recording system of a magnetic disk apparatus." This invention involves a timing control method and system that performs recording and reproducing operations using timing signals and servo signals that are prerecorded on a magnetic disk. The system identifies timing signals through a detection circuit, which responds to a pulse generated by a pulse generator that is sensitive to the revolution speed of the magnetic disk. The servo signals are then extracted based on the timing signal as a reference, allowing for the generation of various signals necessary for read/write operations. Notably, the timing signals are recorded with a single feed quantity smaller than the track width, utilizing a timing signal recording system that features an incrementally movable mechanism for the head and a recording circuit for capturing timing signals at respective stop positions. He has 1 patent to his name.
