A piggyback actuator indispensables for a spin-stand system that evaluates high density magnetic recording, because magnetic recording head must follow a very narrow track precisely on a high speed rotating disk for a read-back signal evaluation. The authors had designed the Nano-Motion Actuator of 10nm spec, which was applied for the spin-stand. However, the actuator can not apply for a pre-write servo disk and a discrete disk, because when these types of disks are clamped on an air-spindle, eccentricity between the disk center and the center axis of the air-spindle occurs. Since the error of the eccentricity reaches to one handled micron meter, a new Nano-Motion Actuator of large work distance is required.
