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 intertwisted together by a motor or the like which is connected to one ends thereof, so that the other ends of the slender rods are finely displaced against the force of a urging means, such as a coiled spring. Thus, it is easy to make the apparatus noise and motor capacity small.

Abstract: A head driving apparatus for displacing a magnetic head comprises a plurality of slender rods (2), the respective ends of which are fixed to one another. The slender rods are twisted together by a motor (7) or the like which is connected to one end thereof, so that the other end of the slender rods are finely displaced against the force of an urging means (14), such as a coiled spring. Thus, it is easy to make the apparatus noise and motor capacity small.
