Design of a high performance linear head positioner fitted for an optical disk drive is reported. First, a flat and small positioner structure with a linear motor consisting of one coil and two magnetic circuits is invented. Next, a new design method to make drive force large, motor size small, and resonant frequency high is discussed by combining motor design with vibration analysis. Finally, the flat and small head positioner with 4.8 N at 1.6 A and about 6 kHz resonant frequency is developed by this design method.
