摘要： A head positioning system includes data head arms for supporting a data head, support head arms for supporting a support head, and a head actuator for rigidly moving the data and servo head arms as a unitary structure. When there is mounted an amplifier or the like is mounted on at least one of the head arms to change the warping amount depending upon the change in the environmental temperature, a portion of the head arm on which the amplifier is mounted is cut away therefrom but is left partly connected thereto, so that the head arms are all warped in nearly the same amount.
