5. A suspension comprising:
a flexure including:
a slider tongue with a proximal end and a distal end, the slider tongue including a leading edge at the proximal end,
a magnetic read/write head slider attached to the slider tongue at the distal end,
at least one actuator affixed to the slider tongue, between the proximal end and the distal end, and
a set of dampening devices extending outwardly from the leading edge of the slider tongue along a same plane as the slider tongue, the set of dampening devices including at least one dampening device at each corner of the leading edge and at least two dampening devices positioned between the dampening devices at each corner of the leading edge, each of the set of dampening devices are configured with an end formed to soften an impact of the at least one dampening device against the load beam to reduce an impulse during a non-operational shock event; and
the load beam including:
a mounting surface configured to receive the flexure, and
one or more damping material positioned at a location of where the slider tongue contacts the mounting surface of the load beam during the non-operational shock event.
