Abstract:
1. An assembly, comprising: a suspension including a flexure and a load beam disposed at an upper part of the flexure, the flexure including a first flexure body to which a slider is coupled, a second flexure body spaced apart from the first flexure body and a pair of bridges connecting the first flexure body to the second flexure body; and a piezoelectric microactuator coupled in its entirety to each of the bridges of the flexure and configured to control at least one of an angle between the load beam and the flexure in a pitching direction and an angle between the load beam and the flexure in a rolling direction by being extended or contracted when electrical current is applied thereto; and a plurality of traces disposed on a dielectric layer having a pair of outriggers that are supported by a pair of protrusion supporting portions that each extend from one of the pair of bridges of the flexure, the plurality of traces include traces for electrically connecting to a read/write head on the slider and traces for electrically connecting to the pair of piezoelectric microactuators; and wherein the traces that electrically connect to the pair of piezoelectric microactuators extend from the dielectric layer along the protrusion supporting portions to the piezoelectric microactuators located on the bridges.
