A head suspension assembly including a load beam having a rigid region, a
mounting region on a proximal end of the load beam, and a flexure on a
distal end of the load beam. The flexure has a read/write head attachment
region for supporting a read/write head on the distal end of the load
beam. Deformation of the head suspension assembly displaces the head
attachment region. A strain transducer circuit that acts as a strain
gauge is mounted on the head suspension assembly. The resistance of the
transducer circuit varies with strain in the circuit, which, in turn,
varies with displacement of the read/write head. The magnitude of
resistance change of the transducer circuit indicates the magnitude of
head off-neutral motion.
