A head gimbal assembly having a suspension and a read/write head is
provided. The read write head is attached to a flexure tongue of the
suspension. Heating elements on arms of the suspension, set on either
side of the suspension tongue, are used to alter flight characteristics
of the read/write read such as pitch and roll. Due to differences in the
coefficients of thermal expansion of the materials that comprise the
arms, the arms bend when heated. Varying the heat output of the heating
elements changes the temperatures of the arms, which changes the degree
to which the arms are bent. The heating elements can be portions of
traces in a trace layer. Control circuitry is provided to control the
heating of the heating elements to maintain desired values of the flight
characteristics.
