Magnetic head driving apparatus

摘要

An apparatus for driving a magnetic head including a monolithic bimorph member. A first end of the monolithic bimorph member has the magnetic head fixed thereto, and the other end thereof is fixed to a support member to be supported by the support member. The monolithic bimorph member comprises a piezoelectric ceramic sintered body formed from a plurality of electrodes stacked alternately with ceramic layers. The plurality of electrodes includes first and second electrode groups which are electrically connected with each other by conductors in through holes. The through holes are provided in portions of the sintered body close to the end fixed to the support member.
