DSA suspension for HDD (DAIKAKU)
■The parts are springs supporting magnetic heads in hard disk drives, and a height of 10 nanometers or less from the high-speed rotating disk is constantly maintained. Furthermore, the magnetic heads can be moved to a target data track at high speeds among data tracks that are tightly arranged with gaps of 0.1 micrometer or less. In order to make high-speed magnetic head positioning more precise and improve the recording density of hard disk drives, minute actuators that contain piezoelectric elements have been built-in.
■Furthermore, to realize this level of functionality, large amounts of technology and know-how, including patented technology, have been applied. This includes die machining technology that can bend or draw thin plates with a thicknesses of dozens of 10 microns in size, highly precise adhesive application and chip bonding technologies for mounting piezoelectric elements in complex shapes, as well as production line technology that enables automated high-speed operation across all processes.
●Product features
