摘要： In a dynamic electric test, a head slider is to be fixed positively to a suspension and to be removable easily from the suspension in accordance with the result of the test. In one embodiment of the present invention a head gimbal assembly includes a head slider, a gimbal and a load beam. The head slider is disposed on a gimbal tongue and is held with an urging force of a resilient clamp at a position between the resilient clamp formed on the leading side of the head slider and connecting terminals formed on the opposite side thereof.

摘要： Embodiments of the present invention relate to approaches to effectively let noise on a head slider bonded to a silicon substrate of a microactuator, escape to the ground. A head gimbal assembly (HGA) according to an embodiment of the present invention comprises a microactuator bonded to a gimbal tongue. The microactuator comprises a piezoelectric element and a movable part for moving in response to expansion or contraction of the piezoelectric element. The motion of the movable part causes a head slider to slightly move. The microactuator further comprises a conductive path including an impurity-containing silicon layer formed on the silicon substrate. The conductive path transmits electric charge of the head slider to a suspension. The conductivity of the impurity-containing silicon layer is lower than the one of the silicon substrate so that the noise charge of the head slider may escape to the suspension.
