ABSTRACT:
A lightweight assembly for suspendingly supporting a pair of magnetic read/write heads and associated sliders from a head-positioning arm, for use in disk type mass storage units. The assembly is formed entirely of aluminum and is intended for mounting to an aluminum arm. A single, unitary flexure supports both head/slider assemblies. The middle of the flexure is secured to the arm, with the longitudinal axis of the flexure transversely spanning the arm so as to support each head in cantilevered fashion, one on each side of the arm's longitudinal axis. A single unload needle can be inserted in a channel running parallel to the longitudinal axis of the flexure for removing the pre-load force from both slider air bearings.
