In this paper, we propose a new head positioning mechanism of a magnetic disk storage. The new positioning mechanism is designed for 2.5 inch single disk and single side drive on the basis of the concept of the in-phase positioning mechanism. natural frequency of it's primaly resonance mode is about 12.4kHz. This positioning mechanism is actuated by a voice coil motor attached on the middle of the arm, which is more reliable device than other positioners with micro-actuator. In order to improve the shock durability, we propose a supporting mechanism of the disk drive. Analytical results indicate that a disk drive supported by the proposed mechanism has enough shock durability for 200kTPI.
