ABSTRACT:
Due to the raised operating rotation speed, it has become an important technical theme to reduce fluid vibrations caused by high speed air flows passing the wiring extension in a head gimbal assembly in order to raise the positioning accuracy for higher density recording. Embodiments of the present invention provide a spring structure to the wiring extension. In a wiring extension holding section formed on the carriage side, the wiring extension is retained at the center of the groove of the holding section by the repulsive force of spring members. By preventing the wiring extension from being directly subject to high speed air flows generated by a high-speed rotating disk, this structure is intended to suppress vibrations of the wiring extension caused by high-speed air flows passing the wiring extension.
