Latest Patents
One of Nakazawa's latest patents is titled "Magnetic head actuator having finely movable tracking device." This invention features a magnetic head actuator equipped with a finely movable tracking device that incorporates a piezoelectric element. The design allows for easier wiring to the piezoelectric element, thereby reducing issues such as wire breakage and continuity defects. The actuator's construction includes a portion of an FPC board resin base that is removed to expose part of the feeding line extending onto a voltage impressing electrode. An electrical and mechanical connection is established between the electrode and the exposed feeding line using methods such as ultrasonic bonding, Au ball bonding, or stud bumping.
Another notable patent is "Magnetic-head gimbal assembly capable of reworking and its production." This patent outlines a method for mounting a flexible flexure, which has a slider fixed to it and an electro-magnetic conversion element integrated. The process involves joining a main flexure to a load beam, inspecting the characteristics by floating the electromagnetic conversion element onto a magnetic disc, and if necessary, removing the main flexure for reworking.
