Abstract:
1. A suspension assembly for use in a magnetic disk drive, including a load beam and a flexure assembly, the flexure assembly comprising: a metal layer where there are formed a fixing portion fixed to the load beam, an arm portion extending from the fixing portion, and a flexure tongue having a moving-side limiter coupling portion defined thereon and supported by the arm portion, wherein the arm portion includes a first arm portion and a second arm portion formed symmetrically with respect to a longitudinal axis of the load beam, a first fixing-side limiter coupling portion is defined at the first arm portion, a second fixing-side limiter coupling portion is defined at the second arm portion, a first moving-side limiter coupling portion and a second moving-side limiter coupling portion are defined at the flexure tongue; an insulating layer including a wiring lower layer portion and laminated on the metal layer; and a dielectric limiter having a gross length larger than a between-coupling-portions distance between a fixing-side limiter coupling portion defined at a portion other than the flexure tongue of the flexure assembly and the moving-side limiter coupling portion and coupling the fixing-side limiter coupling portion to the moving-side limiter coupling portion, and the dielectric limiter is composed of a first dielectric limiter coupling the first fixing-side limiter coupling portion to the first moving-side limiter coupling portion and a second dielectric limiter coupling the second fixing-side limiter coupling portion to the second moving-side limiter coupling portion.
