Embodiment Construction
[0040] Conventional HGAs have a large cantilevered tongue area and thus require a parallel gap. However, such a structure easily damages the piezoelectric element, as described above. Therefore, the present invention aims to reduce the size of the tongue area, reduce or even eliminate the need for gaps, and ensure the performance of the HGA even when vibrations occur.
[0041] Embodiments of the present invention will now be described with reference to the drawings. FIG. 2 a is a perspective view of a HGA with a thin-film piezoelectric microactuator according to an embodiment of the present invention. The HGA 200 shown in FIG. 2 a includes a load bar 204 , a flexible member 209 , a pivot member 213 and a substrate 212 . The magnetic head 210 is partially installed on the top area of the tongue of the flexible member 209 and the bottom area of the tongue of the flexible member 209 . Two piezoelectric elements 202 are installed in the middle area of the flexible member ...
