Abstract

A hinge plate is bonded to a base plate and a load beam in a head suspension assembly. The load beam includes a wide section and a narrow section extending forward from the front end of the wide section. The head suspension assembly allows the load beam to have a narrower width based on the narrow section. The load beam is thus allowed to enjoy a reduced weight. The mass is reduced at a position distanced from the centerline of the load beam. This results in a reduction in the inertial force around the centerline in the load beam. The inventors have demonstrated that the resonance frequency of the first torsion mode is allowed to fall in a higher frequency range. The resonance of the head suspension assembly can be reduced.
