Latest Patents
Ohtsuka holds a patent for a "Head positioning mechanism for magnetic disc memory device." This invention involves a magnetic head positioning mechanism that accurately positions a magnetic head carried on a carriage at a specific location on a magnetic disc. The mechanism utilizes the movement of a belt mounted to a motor spindle of a step motor. By pulling one end of the belt, which is wound or unwound around a motor pulley, the mechanism applies a constant rotation torque. This design effectively eliminates adverse effects caused by the dead zone due to the hysteresis phenomenon of the step motor. Additionally, the rotation torque is consistently applied to the step motor by pulling the carriage in an access direction, thereby improving the positioning accuracy of the head.
