Head suspension having a jumper configured with an escape recess for protecting an insulating cover layer of the jumper from being abraded by an edge of a base plate

Abstract

A head suspension including a base plate, a load beam, an actuator element to be deformed to move the load beam relative to the base plate, and a jumper having a first end electrically connected to the actuator element, an intermediate part extending over a base plate edge of the base plate, and a second end electrically connected to a flexure, to supply power from the flexure to the actuator element. The jumper is composed of an insulating cover layer, a conductor layer, an insulating layer, and a metal layer that are laid one on another. The conductor layer is diverged in a direction in which the layers of the jumper are laid one on another, to form an escape recess to avoid an edge of the base plate edge to protect the insulating cover layer of the jumper from being abraded by an edge of the base plate.
