ABSTRACT:
A suspension for a rigid disk drive suspends a magnetic head over a recording disk in a cantilever fashion. The suspension includes a load beam and a spring assembly which are integrally formed together. The spring assembly includes a bonding tab suspended within the plane of the load beam by two flexible longitudinal arms connected to two flexible transverse arms. The flexible arms permit the bonding tab to roll about the longitudinal axis and pitch about the transverse axis, while preventing the bonding tab from sticking in an off-axis position. The suspension design also minimizes the effect of suspension torsional resonance on the magnetic head by positioning the bonding tab within the plane of the load beam. In addition, the bonding tab defines an aperture which receives a protuberance of the magnetic head to precisely index the magnetic head with the bonding tab, and thus center the magnetic head about a load support point.
