Abstract
Embodiments of the present invention provide a suspension assembly having a dielectric limiter. According to one embodiment, the suspension assembly includes a load beam and a flexure assembly. The flexure assembly includes a metal layer where there are formed a fixing portion fixed to the load beam, main rings, and extending from the fixing portion, sub-rings, and a flexure tongue having moving-side limiter coupling portions defined thereon. Fixing-side limiter coupling portions are defined at the main rings. Dielectric limiters each have a gross length larger than a between-coupling-portions distance between a fixing-side limiter coupling portion and a moving-side limiter coupling portion, and couple the fixing-side limiter coupling portion to the moving-side limiter coupling portion.
