Head suspension assembly including a flexure having rails arranged for interfacing with a head ramp

摘要

An improved head suspension assembly employs a wider and stiffer load beam and flexure having univeral lateral stiffness and a higher natural frequency. The flexure is a unitary configuration having a pair of rails positioned along opposite sides of the flexure. These rails are produced by bending a portion of the flexure material into a bend to form a projecting member arranged to project toward a surface of the load beam to which the flexure is mounted. In this way, the bend faces away from the load beam for interfacing with a ramp to move a head mounted to the flexure away from a disk. This configuration prevents flexure etched edge contact with the ramp and subsequently chipping or other damage to the head suspension assembly.
