Magnetic head apparatus with microactuator having function of short-circuiting both electrodes of epiezoelectric elements and method of manufacturing the same

摘要

The supersonic cleaning of a magnetic head apparatus is executed while the control conductive pattern and the conductive leaf spring are electrically connected by means of soldering, and the conductive leaf spring is grounded. This makes it possible to prevent the accumulation of electrostatic charges in the piezoelectric elements on the magnetic head apparatus, thereby preventing the development of surge current or reducing the intensity thereof, and reducing the damage to the reproducing elements and the recording element mounted on the slider of the magnetic head apparatus.
