ABSTRACT:
A head driving apparatus for displacing a magnetic head comprises a plurality of slender rods, the respective ends of which are fixed to one another. The slender rods are twisted together by a motor or the like which is connected to ends of the rods thereof, so that the other ends of the slender rods are finely displaced against the force of an urging element, such as a coiled spring. Thus, it is easy to make the apparatus operating noise not noticeable and the motor capacity small.
