Latest Patents

Osamu Itou holds a significant patent titled "Device for driving and controlling optical head for use in optical disk." This invention involves a sophisticated mechanism designed to drive and control an optical head by creating a spot of light on an optical disk featuring multiple tracks. The device utilizes a pair of optical detectors to detect light reflected from the spot on the disk, facilitating precise operations.

In detail, the device comprises a head actuator responsible for moving the optical head's movable portion radially across the disk. It also includes a speed detector that measures the track-crossing speed of the spot and a reference speed generator that produces a reference moving speed signal while accessing a target track. The speed of the movable head portion is regulated based on this reference speed signal, allowing for a smooth approach as the light beam spot nears the target track.

Moreover, a speed error detector identifies the difference between the outputs of the reference speed generator and the speed detector. An integral aspect of the invention is the magnification change circuit, which amplifies the outputs when the distance between the light beam spot and the target track becomes critical, ensuring enhanced control in real-time.
