Latest Patents
Maeda's latest patents include innovative designs that enhance the performance of magnetic disc devices. One of his patents is titled "Head arm structure mounting a circuit element in a magnetic disc device." This invention features a head positioning system that includes data head arms for supporting a data head, support head arms for a support head, and a head actuator for moving the data and servo head arms as a unitary structure. The design allows for an amplifier to be mounted on at least one of the head arms, which adjusts the warping amount based on environmental temperature changes. A portion of the head arm with the amplifier is cut away but remains partially connected, ensuring that all head arms warp uniformly.
Another significant patent is the "Dual magnetic head mount." This invention involves a magnetic head that records and reproduces signals using cores incorporated in two sliders positioned on either side of a flexible magnetic disc. The sliders are supported by gimbal flexures that provide omnidirectional degrees of freedom. One slider is pressed against the disc by a loading spring, while the other is fixed in an optimal position relative to the disc's surface.
