Head supporting assembly, head driving assembly, and disk drive apparatus

摘要

A head supporting assembly having high flexibility, while applying a necessary and sufficient pressing force to a head, excellent in shock resistance, and providing a stabilized pressing force not affected by manufacturing variations, and a head driving assembly and a disk drive apparatus using the same. The head supporting assembly is configured to have a base arm provided with a rotation-supporting portion for supporting a head supporting member for rotation in a direction vertical to a disk surface and a resilient member having one end thereof connected to an end of a supporting arm and the other end connected to the base arm. The rotation-supporting portion of the base arm is provided at such a position that a head mount is allowed to be displaced thereto by pressing of the rotation-supporting portion in the pressing direction.
