Latest Patents
One of Iwamoto's latest patents is a charge remover for magnetic disks. This invention involves a loading/unloading type magnetic disk unit that includes a magnetic disk rotated by a motor and a head slider bearing a magnetic head. The head slider is designed to be movable above the magnetic disk due to a driving mechanism. A key feature of this invention is the inclusion of at least one projection made of a highly conductive material on the surface of the head slider. When the magnetic disk unit operates, conduction to the spindle motor is discontinued after a predetermined time, allowing the head slider to float lower and make contact with the magnetic disk. This contact enables the removal of any charge on the magnetic disk through the housing of the unit via the head slider.
Another significant patent involves the design of the head slider itself. This head slider comprises a slider body with an air bearing surface and a tapered surface adjacent to the air introducing end of the air bearing surface. The design features an adhesion-free slider structure, including at least one first pad and one second pad, strategically placed to optimize performance. The distance between these pads is carefully determined to enhance airflow and functionality.
